Road Guy Rob comes to my city! Roundabouts are not magic and can fill up during peak hours. They work best when traffic is low or is balanced. Traffic still clogs up at Carmel High during peak hours with Lexington and RIchland being one lane roundabouts and Main St congestion with only one lane each direction. How ironic that on 136th St, they put a traffic light in the middle of the roundabout only active during peak times going to the school. Even though they can clog during rush hour (Spring Mill and Main in the mornings), it is definitely an improvement over 4 way stops.
Sedona, AZ tried roundabouts as a replacement for most of the traffic lights in their downtown area. I will say it's a major improvement over the old traffic lights, but 12pm on a Saturday in July still means it takes over 30 minutes to drive 2 miles (down from 45 minutes) because of all the congestion. Roundabouts are wonderful for many uses but throwing in too many cars along with confused tourists stopping in the middle of the road negates a lot of what makes them great.
@@blazertundra I think where roundabouts shine the most are entry and exit ramps for highways. In Carmel on Keystone Parkway, we have “dogbone” roundabouts on overpasses. It allows cars to enter and exit to and from the highway without any lights. DDI exchanges are great as they eliminate left turn lights for entering a highway, but the dogbone roundabout overpass could be superior to DDIs.
The problem with Sedona is no public transit. You have private transit for the tourists but public bus lines going down US-89A or SR-260 would be a major improvement. What really sucks are the employees who have to travel from Cottonwood to work there since no one can afford to live close by to where they work.
@@garcjr They need low cost park and ride lots in Cottonwood and Oak Creek, with shuttle busses regularly going to and from Sedona. Also have tour busses that run predictable routes and times, like Grand Canyon. The best fix would be to get cars off the street by making busses more convenient without making life miserable for the people trying to pass through to reach Oak Creek Canyon.
In Sacramento, a lot of roundabouts _still_ have stop signs on only _two_ entrances. I wish the 'roundabouts are the same in California' comment was actually true. Massachusetts and Pennsylvania have particularly weird and dangerous ones everywhere.
I swear that Road Guy Rob should be required viewing for all transportation graduate students. He brings the great real world examples out of the textbook in the most refreshing and compelling way!
These videos are very encouraging, too! I love the fact that we got to see some of the politics behind the scenes and the responses. I don't appreciate not being able to left turn, but not being able to left turn means having to left turn, which is liberating.
No, you don't understand, your expensive landscaping proposal is going to block my ability to make a turn across traffic into the church! You are stepping on my freedom!
I grew up in Fishers, IN (the town right next to Carmel) and its absolutely insane what Carmel has done in terms of vehicle infastructure! Fishers now as well. Both cities are great examples of tax dollars actually going to good use.
James Brainard is an under-the-radar key to the future of suburbia if it's going to have a future in this country. I've long figured his success was that he talked like a Republican but walked like an urbanist. The rest of that town is pretty cool as well, compared to most other places in its category.
I nearly got caught out by one of the rotaries in the US. Coming from the UK you basically assume any doughnut shaped junction is a roundabout. Turns out it was really just a 4 way junction with an island in the middle, with stop signs on two of the roads.
We have a double roundabout in our neighborhood. When there’s low traffic I like to go around the two circles and then around the whole thing at least once. Yeah, it doesn’t take much to entertain me😀
I'll be the roundabout The words will make you out and out I spend the day your way Call it morning driving through the sound And in and out the valley
One roundabout is okay. 160 is way better!! The little roundabouts next to the freeway on-ramps which you will get to next video, are so convenient. All these roundabouts in town encourage you to stay and and not leave to towns with lights. Stop lights are so ridiculously wasteful.
That's true. Neighboring Noblesville and Fishers have quite a few roundabouts, too. They've seen how well it's worked in Carmel, and are taking a page from their book. It also makes traveling into Noblesville and Fishers a bit more comfortable, since it's not a stark change coming from Carmel. I've read that Noblesville and Fishers are definitely not zealots in the way that Jim Brainard is, so they're not aiming to be stop light/sign-free. But they are strategically adding roundabouts where their research shows it will help with traffic the most.
I don't hate traffic signals (stoplights). But I do see that when *ALL* the intersections are roundabouts, something pretty magical happens. Which I'll go into deeper detail over the next 2 videos.
My city put a roundabout at the intersection where one of my best friends was killed in a car accident.He was pulling out from a street next to the business he just left and got t-boned by a 15 yr old doing 20+ over the speed limit.(you could get a license at 15 back then) Yea they put one in. About 22 years later. In 2022
The first roundabouts I've driven on used to be the rotaries in Gardner, MA. They are at the on/off ramps for a smaller state highway. When I was a kid in the 1970's, all vehicles had to stop before entering the rotary. When they transitioned it to a roundabout, all they did was narrow the lane by adding sidewalks and some grass between the sidewalk and the pavement, then tore out the stop signs, replacing them with yield signs.
They recently redid/repainted at least the western one too, implementing in a sliplane into the westbound offramp into downtown (if I'm getting the directions correct...) but then right up the road is a GIANT "rotary" around the Hannafords, which got a signage flip at one point of the "traffic triangle" about 5 years ago so that the *triangle* has to yield rather than those entering the triangle. Now if only they removed the traffic lights about 50 miles east of there along that same highway...
@@Roccondil Of course then you get bad execution like in northern Princeton on Rt 140 where the rotary is so tight that tractor-trailers end up rolling the trailer over the low decorative median.
@@MonkeyJedi99 That low median/hub I am pretty sure is MEANT to accommodate the tractor-trailers because they knew that curve was going to be too tight, while still keeping regular traffic at the correct radius. Over in Fitchburg near Crocker Field there's an even SMALLER rotary that's got a similar low median as its hub, not even any bush to decorate the center, as it too is meant to allow large trucks to navigate it over that hub.
Persuading people is more than data. We think we're rational creatures --- but we're also very emotional. And once people can try a roundabout and realize it isn't scary, they don't feel the need to fight.
Americans (and Canadians where I am) seem to think our way is better since we are the new world....but alas, the roundabout is one idea from the old world that is better and we are now figuring it out. Now this said, Rob, you need to go to Swindon England and take a look at that Pentagon 5 ring roundabout. The Brits call to a mix master. I think that is a level of crazy we can say no to
We need more.local officials that have spent time abroad like that mayor did in college. Being exposed to different ways of doing things sparks curiosity and inventiveness. The guys was a lawyer but ended up with the traffic engineering bug.
@@PrograErrorYep. His law background is probably more useful being mayor, but his curiosity and looking for how to improve things... That's the key mindset and very 'engineer'.
We need more PEOPLE who have traveled abroad and realized not every place that isn't middle America is a 3rd world country. Too many in general seem to think any idea that isn't their own or person/place that isn't exactly like them is somehow evil.
Travelling to Melbourne, Australia completely changed my mind on trams. I used to think they had no place in modern cities but now I'd force every politician to visit their downtown. Was literally bummed when I got home and had to drive myself everywhere.
Yes, to different (better) ways of doing things! I went to Europe in 1973 with people from my high school. The adults in particular were commenting on how both men and women shared the same restrooms. But all the stall doors had little red/green markers on the latches indicating whether they were occupied or not. Here it is, 2024, and I consider my self lucky if I find a stall with such a latch. Except on portable toilets--all of those have them. And these days, it seems like half the people don't even know to knock before trying to open the door.
Seen a few videos on this Mayor and I absolutely love what this guy has done. I spend every day yelling at my city's traffic light system (all of which are out of sync) often asking "Why is there even a light here" as I'm stopped for 2 or 3 full minutes waiting for an unnecessary light turn green again. America needs MORE ROUNDABOUTS and FAR LESS LIGHTS!
Because old people and folks towing large trailers have basically zero hope of navigating a roundabout built on the dimensions of a former intersection. Roundabouts are great for roads handling low to mid volume traffic, but atrocious at high traffic roads in the US. Partly due also to the brilliance of the EPA and it's CAFE requirements essentially encouraging the production of larger automobiles in the states.
Myth busters did a thing about roundabouts which proved that they are better than lights. I live in the UK so got used to roundabouts and agree, they are safer and move more traffic than lights
They're better until you hit a certain level of traffic density in which case they turn into bottlenecks and get lights installed anyway, I also live in the UK and that's the case for the roundabout built at the northern end of where I live.
Putting roundabouts on either end of school roads are brilliant. I live in England and we have a bunch schools set up like that, and it’s usually a great system. There are limitations and drawbacks sometimes, but they’re excellent a lot of the time.
As a Traffic Engineer I absoletly love your channel Rob!! I really enjoyed this video, the story of James Brainard bringing roundabouts to Carmel is one of my favorites!
I grew up in a small town that had no traffic and no stoplights and one ornamental traffic circle. So I grew up knowing how to use them, but thinking they only worked when there wasn't any traffic. Then I moved to a large city with a big traffic circle at a major intersection except that it had 4 lanes going through the middle of it and stoplights all over the place. Really gave traffic circles a bad name, and it was removed in favor of an eight-lane-wide intersection with poorly timed lights. So when the idea of "roundabouts" was brought up years later, everyone who remembered that 💩-show of a traffic circle came out in droves against anything that resembled it (I admit being skeptical myself). Instead we got a bunch of flyovers and grade-separated intersections. Then I visited the UK and saw how they're *supposed* to work and now I vote for them whenever I can.
While roundabouts are great under the right conditions, there are a LOT of intersections where the conditions are right. We should have a lot more of them in our town. The problem is that in our town, people want to funnel all the traffic onto the street-level state highway that runs through town, but then that highway gets congested and people race down all of our side streets as an alternative. It would be better if we had many trafficways parallel to the state highway with roundabout intersections. Keep traffic moving. Keep traffic calm and safe. Everyone would win.
The Carmel roundabout disease has metastasized its way northeast - we now have a large number of them in Fort Wayne, and TBH, I do like them way better than signalized or 4-way stop intersections. We also have the bizarre diverging diamond interchange at a few of the interstate junctions here as well. This area of the country in 2024 is a great place and time to be a road geek.
Not to spoil your next video, but having grown up in Carmel just before all these roundabouts were put in, and living right next to the highway you are going to talk about I know exactly which highway you are talking about. It was not crossable by foot at all. When I show my relatives what they did to that particular intersection I think you are going to talk about in you next video, they are blown away (as am I) by the way roundabouts changed that intersection. Also, growing up in Carmel is why I continue to pronounce Caramel as Carmel and I refuse to change.
Fomer Indy northsider (south of 96th, though). Brainard has worked a genuine miracle, and it's great to see the roundies bleed into Indy, Noblesville/Fishers, and Zionsville. There's even a few now over in my old home neighborhood in Geist/Castleton.
When I visited Iceland in 2017, the capital city Reykjavik had only stop signs on narrow streets; but once you crossed into Hafnafjordur, that city used roundabouts along its principal roads. That combo made driving around Hafnafjordur a joy.
The Australian Roundabout Specs are fine for Australian roads, the reason they were inadequate for the USA is because your roads are wider than ours are. Even just half a foot per lane adds up with multi-lane highways.
Nice! I look forward to seeing roundabouts from the perspective of pedestrians and cyclists in future videos! The one thing Carmel probably needs is a bus service; it does not really have public transport at all. Buses probably won't get in as bad of traffic with roundabouts but a dedicated bus way would keep ridership up even during rush hour.
I definitely want see how a pedestrian crosses at a roundabout. I see them in South Bend, so I know doing it right at the roundabout can't be the right way.
I'm not sure Carmel has the density to support it, though, aside from a commuter bus into Indy, as that's pretty much what Carmel is. It's *alright* for peds/bikes, but it can still be a bit rough when crossing through busier streets, as the drivers are still mostly suburban car-dependent/screw-bike-rider soccer mom types.
Every time I’m stuck waiting for a long time at a stoplight and too often having to stop and wait at every single one I think about how bad it sucks and they could all be roundabouts!
I live in west Suburban Indianapolis. The other suburbs in the Indy area have also been adding roundabouts. Even the city of Indianapolis is adding them. They really work much better than a signal or 4-way stop.
12:38: If you've ever driven around inside Stanford university, the entire campus is full of stop signs. If you drive a manual car, that's going to be a huge pain in the ass to traverse.
When I moved to the US from the UK a long time ago I scoffed at the idea of driving a car with an auto box and bought a car with a stick shift. After driving that around US roads, I was like "never again!" and all my cars since have been autos. Roundabouts are much more efficient over stop lights.
In the last 10 years, Stanford has added 4 roundabouts (which each replaced 4-way stops with 2 lanes per direction - what a mess that was) which have really improved things. Hopefully they'll add even more.
I have. Stanford is a beautiful, frustrating campus -- who yells at you when you try to walk inside the library, apparently. (At my less prestigious university, visitors to campus could walk freely inside the library)
@@RoadGuyRob I can maybe excuse it by saying if it's a college campus and the roads should be pedestrian-first (since roundabouts are notably worse for pedestrians, as you've said in your previous videos), but from my few times visiting there, the campus is huge and is full of cyclists so stops signs seem very inappropriate.
Sounds a lot like Arizona State University’s Tempe campus. The main roads going through campus have a lot of signalized intersections, while the side streets tend to have a lot of all-way stops.
Great, great video! You are the best at what you do, and that is saying something. I am currently in Egypt. The govt. is spending huge amounts on road building, and roundabouts are a big part of the plan. The difficulty is lack of driver training (like in the U.S.) The People are confused and don't know what to do about right of way. You are 1000% correct that it lowers the stakes. If someone is wrong, at worst it is a bump. Nobody gets killed.
there are basically only two rules to understand: Everything turns counter-clockwise (which is very intuitive, because you never _cross_ other directions) and traffic within the ring has priority (else it would clog up). Usually people get this relatively quick.
@@kailahmann1823 I'd like to add a third step which I never understood: double lanes. You MUST be in the correct lane before entering the roundabout. The right lane can only turn left and go straight. The left lane can only go straight, left, or u turn. There are no other options. Knowing those rules is key to not getting 'stuck' inside the circle and also not crashing into the driver to your right.
I love every roundabout I've ever had to navigate, except 1. That 1 is in my neighborhood. The roundabout is only 4 car lengths from a traffic light so cars waiting for that light get backed up into the roundabout.
I've seen the evidence first hand. I live near a somewhat busy intersection, especially in the summer*. At one point, it was a simple stop sign. But about 20 years ago, they upgraded to a traffic light. And, a few years ago, they started converting it into a roundabout and have since completed it. One of the roads parallels an interstate, and the section where the new roundabout is is where the interstate climbs a mountain (by Appalachian standards) so weather can be a bit dicy, fog has caused major pileups before, trucks go slow, vehicles catch on fire, etc. So, wrecks and other road hazards that cause the interstate to slow to a crawl or completely shutdown are a common occurrence. When that happens, drivers detour onto the road that goes through this new roundabout. When it was a traffic light, traffic would always back up for miles as the intersection just couldn't handle the volume of cars of a modern interstate. But now, with the roundabout, the backup is much smaller. Extending maybe half a mile. The intersection is still overwhelmed and can't handle the volume of a modern interstate, but the length of the backup is night and day. So, yes, roundabouts are that much better at handling traffic flow compared to a traffic light. *(There's a US highway with interstate exits in either direction, 2 National Park sites just 5 minutes away, and there's a state primary route with dozens of breweries, wineries, cideries, distilleries, and even meaderies. Not to mention the people who live in the area and commute through the intersection.)
Carmel Indiana doing the most. They are showing that we can in fact have safe roads in the US. It just takes effort to undo the damage they have caused.
If we truly wanted safer roads in the US we would make our drivers license examinations much harder similar to Finland's. It's just there are too many lobbyists and voters opposed to such restrictions
@@Mcfunface I totally agree. Getting a license should be way harder. It should also be a lot easier to revoke a license. If someone drinks and drives twice ever it should be permanent revocation imo.
I'm rural, about 35 minutes northwest of Carmel and my god do I absolutely love the roundabouts. I do most of my business in Carmel and anytime I have to drive somewhere else that doesn't have them it's enraging. Of course I hated them when I first moved up here, but that changes pretty quickly. Honestly, having fellow citizens that understand them is a major contributing factor; little bit of mutual trust makes them all the more seamless. The nuances discussed regarding center diameter, angles, etc. are very important. There are some that have popped up in other places in the state and I don't think had the thoughtful engineering put into them that comes from having built hundreds, so are a touch sketchy. Glad they are spreading (even have a couple coming to my teeny town) and happy to see Carmel getting recognition; it's a lovely place.
And in other parts of the country, cities have been adding roundabouts on roads with median transit lines, especially light rail. In Salt Lake City, there’s one at the University of Utah campus. In the Phoenix area, there’s one in Mesa along Main Street, between the Mesa Dr and Stapley Dr stations, and the city of Phoenix is building a few more along south Central Ave. There’s even a roundabout built for a streetcar in downtown Tempe (Rio Salado Pkwy/Ash Ave). The advantage of roundabouts for those transit lines is that you can guarantee priority for transit vehicles, as with light rail, you can add railroad gates.
Carmel is arguably the wealthiest town in the state, and the high school reflects it. I went to a nearby school, and students definitely had posters saying "your dad works for our dad"...
Good stuff about roundabouts! And good on the Mayor of Carmel! As someone in Australia, I'm curious as to how the roundabouts here were "not up to snuff". I do know of some dodgy ones, come to think of it.
An intersection I have to go through quite often recently was converted into a roundabout a couple of years ago. I would frequently have to wait for no traffic or it would back up and I’d have to wait for a second cycle of the light. Especially when turning left from one of the roads. I’ve only had to wait a few seconds at a time since the conversion and most of that is because of drivers that don’t know how to use it. My horn has educated a couple of them.
So instead of your city fixing the intersection by installing sensored lights to replace the timed lights, you have to jam your brakes in front of drivers anyway informally? Doesn't sound like much of an improvement
@@Michael-ex9uoI dunno if Rob is on travel, but his native time zone is California / pacific. So if anything he probably worked on it all night and uploaded it before bed.
Thank you Mayor Brainard to have the vision for these. Last summer we just had a modern roundabout built at Glendale Ave and York Rd in Niagara-on-the-Lake, Ontario Canada. They have 2 slip lanes built in and once it opened up, the wait times are so little, even at a Friday afternoon rush hour, compared to the old traffic light.
Funny thing is at a lot of the intersections that don't see as much traffic narrower lanes and sharper corners would suffice to slow vehicles and it would be a lot cheaper. But because Carmel is so spread out from following the suburban development pattern for so long (even if they are trying to intensify their downtown) their focus is on keeping cars moving even in places where it doesn't make sense to spend that kind of money.
I live in Carmel. I think roundabouts are great specifically for a type of place that Carmel is. An affluent suburb with space to spare, money to burn, and a predictable amount of traffic flow. As Rob hints at for the next video, there are two north/south limited access highways that keep most thru traffic off of Carmel's streets. This leads to a predictable amount of traffic throughotu nearly all times of days. In the suburbs, particularly when Carmel was growing, space doesn't cost much. But in dense urban centers, eminent domaining nearby parcels for a roundabout quickly adds up. Finally, I think the pedestrian aspect on roundabouts, at least as Carmel does them, is mixed. In Indiana, pedestrians do not have the right of way until they STOP, look both ways, then cross unless they have an affirmative pedestrian signal. Which roundabouts lack. And because pedestrians are supposed to follow a roundabout with the flow of traffic, that could mean a pedestrian has to stop and yield up to 7 times in some of the figure 8 roundabouts.
It looked like the next video hint had him crossing 37 & greenfield, but he may be using that to illustrate the previous form of meridian/31 & keystone. In Indiana pedestrians only have to yield to cars at unmarked crossings (jay walking) and signalized crossings, in unsignalized crosswalks (the kind at roundabouts) they do have the right of way and motorists are required to yield. This is actually why there are stop signs for pedestrians & cyclists on the monon, nickel plate & midlant trace trails; otherwise the cars would have to stop & yield to pedestrians and municipalities would have to clean/clear the sightlines for drivers.
With that rule, how are pedestrians supposed to cross the road in rush hour, when there's a nearly constant flow of traffic? In my country we have the same rule, and it sucks. Some drivers think we're supposed to step foot in the roadway to show our intentions, but that's uncomfortable and sometimes dangerous.
@@NewBuildmini The busiest road traffic in Carmel is often away from areas where pedestrians are common. But yes I've stood at the roundabout at US-31 and 116th and it can take a good long time for traffic to clear to make for a safe crossing. In the more pedestrianized, urban core where Rob is for most of the video, there is a lot of courtesy stopping from drivers.
I love your stories, Rob. Speaking of roundabouts, we have a set of intersecting streets here in Colorado Springs, Colorado that has a statue in the middle of the road and it’s a big accident always happening. They finally are starting to talk about putting a roundabout in to solve a lot of the problem.
Very interesting video, looking forward to part two! Living in California, they were a bit late to the whole roundabout thing, but recently it's been getting more and more popular which helps with traffic flow and safety.
This Roundabout deep dive nails it! From their history to the true reason - saving lives. If anyone tells me that they "hate roundabouts", I'll share this video. BTW, smaller roundabouts are a PITA for truckers. Getting around a roundabout and exiting in any direction means said truck must take up the whole width of the road. I drive 18 wheelers. I know. And I still love "roundys", to coin a nickname.
It may be prudent for truckers to go back to using the same sized trailers as Europe. They never increased their maximum length in part due to the amount of roundabouts.
Imagine getting a wind turbine blade around one they put on a bypass that was meant for truckers and oversized loads. They did that locally and now those loads are forced onto far a busier road, but in the next town over technically so the city that put it in doesn't have to deal with the consequences.
Some roundabouts have skirts to let truckers pass through. Not sure if that is the official term: but a raised paved area around the circle that allows trailers to roll over top.
@@jamesphillips2285 This one does, but it isn't enough because the turn is way too tight. Most of the truck traffic now avoids it and has made a already busy through fare far worse or they go straight through downtown of this city which the bypass was design to stop that particular flow. In short the city did not think what they were doing through.
Down here in The Villages, Florida. About once a year a senior citizen goes straight through a round about at full speed, which sends their car into the air Dukes of Hazzard style.
The more you study all these roadway accidents, the more you realize most people simply should never be allowed to operate two tons of steel operating at high speeds. Cities need to return to walking and cycling as being the primary modes of transportation.
I never quite understood the general opposition present in the US against roundabouts. Although there are cases where traffic lights are a better fit (ex. a medium traffic load road perpendicularly crossing an extremely high traffic load road*) in most cases roundabouts are clearly superior by pretty much any metric. * In that case, because people on the roundabout have right of way, the high traffic road would keep occupying the roundabout giving no space for the side road to drain, clogging that one up. And in such a case there's no easy way to build a (cheap) slip road either.
At the low end the same effect on traffic flow rate could be achieved with yield signs in place of stop signs, without any of the pedestrian benefits but in that use case they realistically aren't much different. Medium flow or high flow you have very specific use cases where they improve traffic flow but they can very easily get locked if a new development happens and traffic patterns change. My observation and experience has been in most cases they are a band aid for previous poor planning, or a vanity project and they have a short term placebo effect.
If you grew up in NJ and then moved to another state, that pretty much explains it. NJ would intersect highways with traffic circles, and it was literally a free for all. There was one particular circle intersecting Rt 70 and Rr 73 on Marlton that was both a circle and a regular intersection. It took NJ 4 or 5 decades, but they finally put an overpass in. And NJ has this other oddity called jug handles. They are a way to turn left and come in two varieties. First, go past the intersection and loop back right onto the intersecting road. Second, turn right like an offramp before the intersection and turn left onto the intersecting road away from the main intersection. The first one kind of works. The second is just a disaster because you're still turning left but without the benefit of a light in many cases. So it becomes a dangerous free for all. If you want to understand how to cause crashes with roundabouts, go to Oshkosh, WI, not having the experience with one. They use multilane configurations. You have to carefully watch the road signs and surface markings in order to be in the correct lane. Otherwise you'll end up side swiping other cars trying to exit the roundabout, especially during rush hour.
The only opposition I've personally encountered was from my grandparents. They had never seen a roundabout until their 70s when our city started building them. Stop signs and stop lights were familiar, but roundabouts were too new and chaotic.
If you have an extremely high traffic load road it should be grade separated and made into a highway rather than having traffic lights slowing down that high load of traffic.
Great video! As someone who’s very familiar with Carmel's roundabouts (Moved here in 2021), I really appreciate the detailed history and educational background you provided. It’s fantastic to see how these roundabouts have positively impacted traffic safety in our city. While I do have some critiques regarding Carmel's roundabouts being a bit too focused on speed and the throughput of cars, I want to highlight that roundabouts demand compliance from motorists, whereas traditional intersections technically only request it. Properly designed roundabouts are safer for everyone, not just motorists, by slowing down traffic and providing clearer, safer crossings for pedestrians and people on bikes. Your video does a wonderful job showcasing the progress Carmel has made.
My biggest problem with round-abouts are not that they are inherently flawed, its that people are inherently stupid. To quote Tommy Lee Jones; "a person is smart. People are dumb, panicky, dangerous animals, and you know it." We've gotten a few in the great state of Minnesota, and it boggles my mind how inept people are at traversing them. Was going through a major highway, old fart who shouldn't even have his license, was in the roundabout and slammed on the brakes to let someone enter the roundabout. He had no preconception that he had the right of way, he's not supposed to stop, hes supposed to keep going. This caused me to slam on my brakes, and get rear ended, because the traffic was too complex for someone else to understand. And this isn't even taking into account that large vehicles such as semi trucks and buses have a difficult time navigating these roundabouts.
i mean what do you expect i never even driven on a roundabout either. seen one in Colorado once but that was about 10 years back there not even in schools books still i'm betting you
2 things: first, not all roundabouts are built to the same specs. I just had one built near me that requires 7 turns of the steering wheel to complete a straight passage. Second, roundabouts are a bad idea for snow plows and winter traffic in general. Carmel is fine, anything south of Kokomo is fine, building them in the lake effect snow band is stupid. They reduce accidents 9 months out the year and then double them the other 3 months.
It's crazy to me to think that the USAs first roundabout was built in the 90s. Here in the UK we have almost none of the typical American 4 way intersections, they are all roundabouts. Every single motorway junction has a roundabout or 2. They are just so so so much better.
There is a "round about" here in Portland, OR; on Cesar E Chavez Blvd. And far as I know it has been there before I was born; 1975. The "round about" is NOT a yield sign, but a STOP sign; controlled area.
Begging to differ on the first roundabout thing: Just consulting Google Maps, I would get it if the road system on the D.C. side of the Arlington Memorial Bridge isn't maybe technically a roundabout, but it certainly functions as one, I think. Unless it's change in the several decades since I came upon it. I was a tourist from Canada doing touristy things, and had never used a roundabout before. I had a lot of trepidation when I saw the traffic flow signs on the bridge, but after getting through it I was "WHERE HAVE YOU BEEN ALL MY LIFE!" It's been a long wait, but roundabouts are making a welcomed appearance where I live now.
Great video Rob! I wish we had more roundabouts where I live (suburban Virginia Beach), I'm in the Air Force and have made several trip to the UK and I love their road network. Like you said you just keep moving rather than spending so much time sitting at traffic lights.
They replaced a traffic light with a 5 point, 2 lane roundabout here in Cheyenne WY in the last 10 years. I like it, though, it is a bit scary with it being a 2 lane and people not following the signs. Multiple occasions seeing people cut across a lane they are not allowed to in order to exit. For what it's worth I don't hear of many accidents regardless. That alone says something about the increased safety at roundabouts.
Last 10 years my community has been following suit as well, people still gripe about them but they do help .. just getting people to actually learn how to use them correctly is the trick.. I swear some people are stuck in their ways
When I was learning to driver, NJ had several "circles" that just worked. However with congestive and traffic growth, most were removed for Jug Handles and signals. Then those became congestive, so they tried bridges...talk about costly...then...circles or roundabouts have come back.
"I'll be the roundabout The words will make you out and out You spent the day your way Call it morning driving through the sound And in and out the valley" - Yes, 1971. I had to do it. Nobody else stepped up. I regret NOTHING.
One issue with rotaries with double lanes are drivers that refuse to stay in their lanes! The next issue are drivers that refuse to yield! The concept works with cooperation from all drivers. Thanks Rob. Delightful episode.
9:05 as an Aussie, that hurts my pride a little bit. We're ripping way too many roundabouts out these days, I wish we could take a page out of Carmel's book
True, but as an Aussie who knows how arrogant Aussie engineers can be, it's kind of satisfying that someone who's had such a big impact on the US can takea big dump on them!
Australia are REMOVING roundabouts? That's a shame. In fairness to AUS, he was talking about standards in 1998. Back when the U.S. had NO standards at all. I'm sure the designs have gotten much better over the years.
@@RoadGuyRob don't worry, we're still installing plenty of roundabouts! It's just that sometimes they outlive their usefulness under certain conditions. In some scenarios traffic lights can be a better option.
@@traffic.engineer I have to disagree. Traffic lights operate better for about 2 hours out of every whole day. The rest of the time they cause unnecessary delays.
In every city in the United States, the hardest thing about building a roundabout is building the first one. People are so afraid of them until they drive on one, then they realize that they're much better.
I used to work overseas in the Middle East, and in Qatar, they used to have so many roundabouts! In the Middle East, you take your life in your hands driving on roads there, and roundabouts were common sites for fatal collisions. Eventually, the roundabouts were removed and replaced with traffic signals...which you didn't dare run the red lights on! The traffic deaths plummeted as a result...roundabouts work best on smaller roads like the ones pictured in Indiana, not 8 lane behemoths begging to become freeways.
I didn't know there was a difference between Roundabouts and Traffic Circles. Oklahoma City has two of what must be traffic circles, there is a stop sign at every entrance and I think they are undersized to be useful. These are on NW 10th St. at the NW and NE corners of Saint Anthony's Hospital. The NW one works fine, it's easy to enter and get to your preferred exit, however there is not much traffic on this side. The NE one is a different story. Not only is there a lot more traffic, as it connects to the hospitals main entrance and a lot of other businesses, mostly restaurants, on the streets around it, this side also has 5 streets conjoining at this spot. Since the traffic circles are already too small to handle heavy traffic the addition of a fifth street makes this one dangerous. In some places there is barely a car length between inlets/outlets and since you are coming out of a stop sign you must yield to traffic coming the opposite direction if you want to turn left. Since it's so small it's very hard to determine if another car is going to turn before your inlet which causes many people to hold at the stop sign longer than they should. I've always thought these traffic circles needed to be larger but after watching this I think they need to also be turned into roundabouts. I always thought having to come to a stop before entering the circle was pointless and this video pretty much confirms that. If you're going to make people stop at a stop sign and yield to oncoming traffic before turning left you might as well just have a straight through intersection.
*Rob:* "Nobody's gonna just nail on the gas coming out of the first roundabout here when they see a block down the street there's a second roundabout, right?" *Me:* _[Laughs in Motorcycle]_
From the uk here (having over 10000 roundabouts), it nice to see the US start to take the roundabout in its pride! (Maybe even the ‘magic’ roundabouts lol)
Too bad you're still not in the Indy area, Rob. Right down the road in Beech Grove they just announced they're going to install a "peanut roundabout" and lots of people are up in arms about it LOL
I'm almost 100% certain he's going to discus those in the next video. The preview shows him crossing the intersection of SR37 & Greenfield. I'm betting he's going to show peanut roundabouts on the overpasess there on 37 and others on keystone.
@@RoadGuyRob It used to be a road that you could drive straight through. Little traffic, and the occasional stoplight when someone was coming onto the road from a side street. Now, it's a constant series of chicanes, and the site lines are terrible. All for the five people per hour that turn onto 96th street. Roundabouts have their place, but 96th street was a much better road prior to the roundabout obsession.
@@RoadGuyRob BTW, I love that you're such a road nerd that you asked me for more detail about a random road on the northside of Indy. You and Control City Freak need to collaborate on a project some time.
I grew up in Carmel. The hundreds of roundabouts have only helped with traffic. I remember when it used to take 20-30 minutes to cross the city. Now it takes half the time and feels safer by a large margin
Its a wild feeling where one of my favorite youtubers and the place i live collide...Im currently sitting less than half a mile from where this video was filmed!
It's not odd, it is simply a different time in each time zone. Someone always sees a fresh release in the 3 am hour. It is, what it is, but perhaps, next time, it will be high noon for you.
Much easier to install a roundabout in new construction. Retrofit projects have issues with property acquisition that may shift the roundabout toward a particular quadrant to avoid taking park lands, etc., which can create some nasty curves resulting in signs being knocked down repeatedly and landscaping demolished by trailers. Another problem with retrofits is that many intersections are on a hill. And those directly on a small hilltop create some interesting sight distance issues for drivers unfamiliar with the area. Of course you can install warning signs, but many drivers suffer from signing fatigue and simply tune out excess signage - the yellow ones in particular. There are complex intersections, such as MO I-70 Exit 125, which has two roundabouts and a traffic signal, as there are access roads and exit ramps on both sides of the overpass. I think this example is especially challenging to drivers the first few times they go thru it. The dog bone at Mo I-70 and Range LIne Street, Exit 127, is also challenging, as its a two lane design, but I don't think its quite as bad as Exit 125. Both make me nervous enough to avoid whenever possible. Both are located in Columbia, MO, home of the Mizzou Tigers.
New Jersey use to be the Roundabout capital. When I was a kid, there were roundabouts everywhere. Then in the 70/80's they started to tear them out. There are still a few left but I remember the roundabout days.
Those are technically traffic circles, not roundabouts. They range from pretty efficient (like the one in Lakehurst) to pure chaos (the nightmare at 202 & 206 in Somerville)
Traffic circles are much smaller in diameter, and not at all the same as a roundabout. Here in my Orange County (CA) neighborhood, there are several traffic circles, but if you hit the right angle, you don't even need to slow down while going through them. It's basically just a yield sign.
Rob, a city I would love for you to do is Savannah somebody's comment made me think about it, but you should do a video on Savannah squares. Which work as a traffic calming measure themselves.
Always nice to see a place embrace roundabouts (tho I don't necessarily think they belong in every intersection), just wish it didn't require essentially tricking people into putting them there in the first place..
I used to hate roundabouts. Coming from NY where people didn't know how to use them, people would just blindly blow through them thinking "no stop sign, I can go". I moved to Carmel in 2020, after watching the city grow over 15 years (wife's family is from here). I now like the roundabouts and appreciate them. Approaching the intersection to exiting has never been more than minute and, more often than not, just barely a pause before entering. When traveling outside of Carmel and I get to a red light with no cross traffic, I wonder "why isn't this a roundabout?"
Traffic Circles are nice, until you get to a point of chaining multiple right off the highway. If you happen to be cruising on I-75 in Ohio, take Exit 181 into Bowling Green. We be making chains out of traffic circles
I used to live in Carmel,and now I live in Fishers next door. The roundabouts are spreading, but for low-capacity intersections, they are absolutely wonderful 95% of the time. Any time there is a large number of cars going through, my 20-min commute to Carmel for work turns to 40 minutes. Timing versus traffic is the true key to using them around here. And Brainard, while no longer in office, loved to talk about these roundabouts with anyone he can. He slao helped to revitalize downtown Carmel to a place better than downtownm Indy.
Roundabouts are great in low to medium constant flow traffic areas but once you get to high traffic flow or have inconsistent traffic flow, they become nightmares to traverse. Another thing to think about is traffic lights also give pauses in traffic that allow people to turn out of parking areas or streets. So no roundabouts are not magical wonders but they do give city planners another tool to manage traffic. side note: the point of roundabouts is to keep traffic moving but once vehicles have to stop, for whatever that reason maybe, it defeats the purpose of a roundabout. Also some roundabouts are pita to cross for larger vehicles such as school buses.
Awesome video Rob! As an American driver living in Europe now, I *love* roundabouts. They are so much more efficient and better than 4-way stops (especially) and traffic light intersections! That's why I made a video about them on my channel a couple years ago...they're just great!
I was first confronted with roundabouts 60 years ago in England and Ireland. My first reaction was it’s a crazy way to drive. After negotiating my first three or four I realized how efficient and safe roundabouts can be. I’m 100% in favor of roundabouts!!!
Our high school in Shakopee, MN needs like FOUR roundabouts. The intersection I use every day leaving my neighborhood has people across from me departing the high school 24-7-365. SO frustrating.
Rob, I grew up in Cherry Hill, NJ, where we had a number of traffic circles, all built in the 50’s and 60’s, I believe. Elisburg Circle, Racetrack Circle, Airport circle… and countless others, all along the length of our state highways through the greater Cherry Hill region. (70, 73, 38, 30, 130) All of them were intact when I started driving in 1987 and I loved them. But over the years most of them were destroyed by traffic engineers attempting to address capacity concerns. Some received signals, others were cut in half. Every attempt failed and now all or most of them are gone. OF NOTE: I am told that Route 30, which crosses the USA from the Jersey shore to the other coast out left somewhere (Cali, Oregon, Washington? Who can say) used to have a traffic circle at both ends. We moved to southern West Virginia 16 years ago, and every time we go back to visit family, it makes me sad to see the monstrosities that replaced my beloved circles over the years. They were ahead of their time.
Road Guy Rob comes to my city! Roundabouts are not magic and can fill up during peak hours. They work best when traffic is low or is balanced. Traffic still clogs up at Carmel High during peak hours with Lexington and RIchland being one lane roundabouts and Main St congestion with only one lane each direction. How ironic that on 136th St, they put a traffic light in the middle of the roundabout only active during peak times going to the school. Even though they can clog during rush hour (Spring Mill and Main in the mornings), it is definitely an improvement over 4 way stops.
Sedona, AZ tried roundabouts as a replacement for most of the traffic lights in their downtown area. I will say it's a major improvement over the old traffic lights, but 12pm on a Saturday in July still means it takes over 30 minutes to drive 2 miles (down from 45 minutes) because of all the congestion.
Roundabouts are wonderful for many uses but throwing in too many cars along with confused tourists stopping in the middle of the road negates a lot of what makes them great.
@@blazertundra I think where roundabouts shine the most are entry and exit ramps for highways. In Carmel on Keystone Parkway, we have “dogbone” roundabouts on overpasses. It allows cars to enter and exit to and from the highway without any lights.
DDI exchanges are great as they eliminate left turn lights for entering a highway, but the dogbone roundabout overpass could be superior to DDIs.
The problem with Sedona is no public transit. You have private transit for the tourists but public bus lines going down US-89A or SR-260 would be a major improvement.
What really sucks are the employees who have to travel from Cottonwood to work there since no one can afford to live close by to where they work.
@@garcjr Carmel doesn’t have public transit neither. And we have an affordability issue too (not as bad as Sedona).
@@garcjr They need low cost park and ride lots in Cottonwood and Oak Creek, with shuttle busses regularly going to and from Sedona. Also have tour busses that run predictable routes and times, like Grand Canyon. The best fix would be to get cars off the street by making busses more convenient without making life miserable for the people trying to pass through to reach Oak Creek Canyon.
I used to commute to work along a route that included multiple roundabouts. They all had stop signs on each entrance. Facepalm.
Around here there are several roundabouts that have trafic lights on them some peaktime only some permanent.( West Yorkshire)
My own city has a roundabout with 4 sets of traffic lights!
@@jamesphillips2285 There is one particular roundabout that has EIGHT of them one set on each entrance and one set every 90^ as you progress round.
There's a "roundabout" in Northeast Portland called Coe Circle that has stop signs at each entrance.
In Sacramento, a lot of roundabouts _still_ have stop signs on only _two_ entrances. I wish the 'roundabouts are the same in California' comment was actually true. Massachusetts and Pennsylvania have particularly weird and dangerous ones everywhere.

I grew up in Fishers, IN (the town right next to Carmel) and its absolutely insane what Carmel has done in terms of vehicle infastructure! Fishers now as well. Both cities are great examples of tax dollars actually going to good use.
That mayor singlehandedly created the roundabout fad in an entire developed first world country that was devoid of it prior. Props to him.
Bicycle Dutch covered a lot of the new cycling infrastructure the city recently built.
When I heard he was in office since *1996* (before ANY roundabouts), I got excited to interview him. And even more excited when he said YES.
Fad is definitely the right word for it.
James Brainard is an under-the-radar key to the future of suburbia if it's going to have a future in this country. I've long figured his success was that he talked like a Republican but walked like an urbanist. The rest of that town is pretty cool as well, compared to most other places in its category.
@@jishani1 But at least it's beneficial unlike most fads in the US
I nearly got caught out by one of the rotaries in the US. Coming from the UK you basically assume any doughnut shaped junction is a roundabout. Turns out it was really just a 4 way junction with an island in the middle, with stop signs on two of the roads.
people like you make it look easy to teach people in a fun and great manner.
Thanks!
I love roundabouts. Great to hear how well they've done in Carmel.

Indiana is the only place I've seen a roundabout with nothing in the center to denote it was higher.
During a rain storm that's a fun time.
One roundabout is okay. 160 is way better!! The little roundabouts next to the freeway on-ramps which you will get to next video, are so convenient. All these roundabouts in town encourage you to stay and and not leave to towns with lights. Stop lights are so ridiculously wasteful.
That's true. Neighboring Noblesville and Fishers have quite a few roundabouts, too. They've seen how well it's worked in Carmel, and are taking a page from their book. It also makes traveling into Noblesville and Fishers a bit more comfortable, since it's not a stark change coming from Carmel.
I've read that Noblesville and Fishers are definitely not zealots in the way that Jim Brainard is, so they're not aiming to be stop light/sign-free. But they are strategically adding roundabouts where their research shows it will help with traffic the most.
I don't hate traffic signals (stoplights). But I do see that when *ALL* the intersections are roundabouts, something pretty magical happens. Which I'll go into deeper detail over the next 2 videos.
My city put a roundabout at the intersection where one of my best friends was killed in a car accident.He was pulling out from a street next to the business he just left and got t-boned by a 15 yr old doing 20+ over the speed limit.(you could get a license at 15 back then)
Yea they put one in. About 22 years later. In 2022
rip to your friend
16 year olds driving is already bad enough, 15 year olds driving is literally psychotic and asking for homocide
The first roundabouts I've driven on used to be the rotaries in Gardner, MA.
They are at the on/off ramps for a smaller state highway.
When I was a kid in the 1970's, all vehicles had to stop before entering the rotary.
When they transitioned it to a roundabout, all they did was narrow the lane by adding sidewalks and some grass between the sidewalk and the pavement, then tore out the stop signs, replacing them with yield signs.
They recently redid/repainted at least the western one too, implementing in a sliplane into the westbound offramp into downtown (if I'm getting the directions correct...) but then right up the road is a GIANT "rotary" around the Hannafords, which got a signage flip at one point of the "traffic triangle" about 5 years ago so that the *triangle* has to yield rather than those entering the triangle.
Now if only they removed the traffic lights about 50 miles east of there along that same highway...
@@Roccondil Of course then you get bad execution like in northern Princeton on Rt 140 where the rotary is so tight that tractor-trailers end up rolling the trailer over the low decorative median.
@@MonkeyJedi99 That low median/hub I am pretty sure is MEANT to accommodate the tractor-trailers because they knew that curve was going to be too tight, while still keeping regular traffic at the correct radius.
Over in Fitchburg near Crocker Field there's an even SMALLER rotary that's got a similar low median as its hub, not even any bush to decorate the center, as it too is meant to allow large trucks to navigate it over that hub.
This just shows you that no matter how much evidence there is for something, people will always beat it down for no reason
True. And cost savings always wins anyway in the long run.
Persuading people is more than data. We think we're rational creatures --- but we're also very emotional. And once people can try a roundabout and realize it isn't scary, they don't feel the need to fight.
Americans (and Canadians where I am) seem to think our way is better since we are the new world....but alas, the roundabout is one idea from the old world that is better and we are now figuring it out. Now this said, Rob, you need to go to Swindon England and take a look at that Pentagon 5 ring roundabout. The Brits call to a mix master. I think that is a level of crazy we can say no to
We need more.local officials that have spent time abroad like that mayor did in college.
Being exposed to different ways of doing things sparks curiosity and inventiveness.
The guys was a lawyer but ended up with the traffic engineering bug.
Well... his lawyering did saved his arse on his crusade to put roundabout in the manual...
@@PrograErrorYep. His law background is probably more useful being mayor, but his curiosity and looking for how to improve things... That's the key mindset and very 'engineer'.
We need more PEOPLE who have traveled abroad and realized not every place that isn't middle America is a 3rd world country. Too many in general seem to think any idea that isn't their own or person/place that isn't exactly like them is somehow evil.
Travelling to Melbourne, Australia completely changed my mind on trams. I used to think they had no place in modern cities but now I'd force every politician to visit their downtown. Was literally bummed when I got home and had to drive myself everywhere.
Yes, to different (better) ways of doing things! I went to Europe in 1973 with people from my high school. The adults in particular were commenting on how both men and women shared the same restrooms. But all the stall doors had little red/green markers on the latches indicating whether they were occupied or not. Here it is, 2024, and I consider my self lucky if I find a stall with such a latch. Except on portable toilets--all of those have them. And these days, it seems like half the people don't even know to knock before trying to open the door.
It's so strange seeing "shark teeth" on the road in the USA. I'm so used to seeing them here in The Netherlands.

@@longiusaescius2537get outta my swamp!
Seen a few videos on this Mayor and I absolutely love what this guy has done. I spend every day yelling at my city's traffic light system (all of which are out of sync) often asking "Why is there even a light here" as I'm stopped for 2 or 3 full minutes waiting for an unnecessary light turn green again. America needs MORE ROUNDABOUTS and FAR LESS LIGHTS!
I'm glad you finally got to do a video of this town Carmel
I love roundabouts as much as the next Carmel resident, but Rob has got to be the 5,283rd TH-camr to do a video on Carmel roundabouts.
My town put in roundabouts 15-20 years ago and people are still complaining... Those same people just stop and wait for traffic to clear before going.
Because old people and folks towing large trailers have basically zero hope of navigating a roundabout built on the dimensions of a former intersection. Roundabouts are great for roads handling low to mid volume traffic, but atrocious at high traffic roads in the US. Partly due also to the brilliance of the EPA and it's CAFE requirements essentially encouraging the production of larger automobiles in the states.
It's nearly impossible to enter a busy roundabout with a semi-truck without stopping and waiting for traffic to clear.
@@Mcfunface old people have no business to transact outside of retirement homes
@@Mcfunfaceoh yeah and roudabouts have aprons for larger vehicles. School busses navigate the round abouts here.
Myth busters did a thing about roundabouts which proved that they are better than lights. I live in the UK so got used to roundabouts and agree, they are safer and move more traffic than lights
They're better until you hit a certain level of traffic density in which case they turn into bottlenecks and get lights installed anyway, I also live in the UK and that's the case for the roundabout built at the northern end of where I live.
And cheaper since they have zero operating cost. And maintenance is just standard road maintenance.
Putting roundabouts on either end of school roads are brilliant. I live in England and we have a bunch schools set up like that, and it’s usually a great system. There are limitations and drawbacks sometimes, but they’re excellent a lot of the time.
As a Traffic Engineer I absoletly love your channel Rob!! I really enjoyed this video, the story of James Brainard bringing roundabouts to Carmel is one of my favorites!
Glad to hear it! (And that you aren't seeing major errors I need to correct!)
I grew up in a small town that had no traffic and no stoplights and one ornamental traffic circle. So I grew up knowing how to use them, but thinking they only worked when there wasn't any traffic. Then I moved to a large city with a big traffic circle at a major intersection except that it had 4 lanes going through the middle of it and stoplights all over the place. Really gave traffic circles a bad name, and it was removed in favor of an eight-lane-wide intersection with poorly timed lights. So when the idea of "roundabouts" was brought up years later, everyone who remembered that 💩-show of a traffic circle came out in droves against anything that resembled it (I admit being skeptical myself). Instead we got a bunch of flyovers and grade-separated intersections. Then I visited the UK and saw how they're *supposed* to work and now I vote for them whenever I can.
While roundabouts are great under the right conditions, there are a LOT of intersections where the conditions are right. We should have a lot more of them in our town. The problem is that in our town, people want to funnel all the traffic onto the street-level state highway that runs through town, but then that highway gets congested and people race down all of our side streets as an alternative. It would be better if we had many trafficways parallel to the state highway with roundabout intersections. Keep traffic moving. Keep traffic calm and safe. Everyone would win.
The solution for your town probably is a commuter lane, but only rich communities get that
The Carmel roundabout disease has metastasized its way northeast - we now have a large number of them in Fort Wayne, and TBH, I do like them way better than signalized or 4-way stop intersections. We also have the bizarre diverging diamond interchange at a few of the interstate junctions here as well. This area of the country in 2024 is a great place and time to be a road geek.
Not to spoil your next video, but having grown up in Carmel just before all these roundabouts were put in, and living right next to the highway you are going to talk about
I know exactly which highway you are talking about. It was not crossable by foot at all. When I show my relatives what they did to that particular intersection I think you are going to talk about in you next video, they are blown away (as am I) by the way roundabouts changed that intersection.
Also, growing up in Carmel is why I continue to pronounce Caramel as Carmel and I refuse to change.
Fomer Indy northsider (south of 96th, though). Brainard has worked a genuine miracle, and it's great to see the roundies bleed into Indy, Noblesville/Fishers, and Zionsville. There's even a few now over in my old home neighborhood in Geist/Castleton.
When I visited Iceland in 2017, the capital city Reykjavik had only stop signs on narrow streets; but once you crossed into Hafnafjordur, that city used roundabouts along its principal roads. That combo made driving around Hafnafjordur a joy.
The Australian Roundabout Specs are fine for Australian roads, the reason they were inadequate for the USA is because your roads are wider than ours are.
Even just half a foot per lane adds up with multi-lane highways.
Nice! I look forward to seeing roundabouts from the perspective of pedestrians and cyclists in future videos! The one thing Carmel probably needs is a bus service; it does not really have public transport at all. Buses probably won't get in as bad of traffic with roundabouts but a dedicated bus way would keep ridership up even during rush hour.
I definitely want see how a pedestrian crosses at a roundabout. I see them in South Bend, so I know doing it right at the roundabout can't be the right way.
pause the video at 1:35. you can see the pedestrian crossing
@@gavrielbaron1597 Yeah but this video still takes a driver POV of roundabouts. Seeing how pedestrians feel is going to be great as well.
Most locals don’t want buses. If it was dressed up like a trolley or something it might pass
I'm not sure Carmel has the density to support it, though, aside from a commuter bus into Indy, as that's pretty much what Carmel is.
It's *alright* for peds/bikes, but it can still be a bit rough when crossing through busier streets, as the drivers are still mostly suburban car-dependent/screw-bike-rider soccer mom types.
Every time I’m stuck waiting for a long time at a stoplight and too often having to stop and wait at every single one I think about how bad it sucks and they could all be roundabouts!
Same
I live in west Suburban Indianapolis. The other suburbs in the Indy area have also been adding roundabouts. Even the city of Indianapolis is adding them. They really work much better than a signal or 4-way stop.

12:38: If you've ever driven around inside Stanford university, the entire campus is full of stop signs. If you drive a manual car, that's going to be a huge pain in the ass to traverse.
When I moved to the US from the UK a long time ago I scoffed at the idea of driving a car with an auto box and bought a car with a stick shift. After driving that around US roads, I was like "never again!" and all my cars since have been autos. Roundabouts are much more efficient over stop lights.
In the last 10 years, Stanford has added 4 roundabouts (which each replaced 4-way stops with 2 lanes per direction - what a mess that was) which have really improved things. Hopefully they'll add even more.
I have. Stanford is a beautiful, frustrating campus -- who yells at you when you try to walk inside the library, apparently. (At my less prestigious university, visitors to campus could walk freely inside the library)
@@RoadGuyRob I can maybe excuse it by saying if it's a college campus and the roads should be pedestrian-first (since roundabouts are notably worse for pedestrians, as you've said in your previous videos), but from my few times visiting there, the campus is huge and is full of cyclists so stops signs seem very inappropriate.
Sounds a lot like Arizona State University’s Tempe campus. The main roads going through campus have a lot of signalized intersections, while the side streets tend to have a lot of all-way stops.
Great, great video! You are the best at what you do, and that is saying something.
I am currently in Egypt. The govt. is spending huge amounts on road building, and roundabouts are a big part of the plan. The difficulty is lack of driver training (like in the U.S.) The People are confused and don't know what to do about right of way. You are 1000% correct that it lowers the stakes. If someone is wrong, at worst it is a bump. Nobody gets killed.
there are basically only two rules to understand: Everything turns counter-clockwise (which is very intuitive, because you never _cross_ other directions) and traffic within the ring has priority (else it would clog up). Usually people get this relatively quick.
@@kailahmann1823 I'd like to add a third step which I never understood: double lanes. You MUST be in the correct lane before entering the roundabout. The right lane can only turn left and go straight. The left lane can only go straight, left, or u turn. There are no other options. Knowing those rules is key to not getting 'stuck' inside the circle and also not crashing into the driver to your right.
I love every roundabout I've ever had to navigate, except 1. That 1 is in my neighborhood. The roundabout is only 4 car lengths from a traffic light so cars waiting for that light get backed up into the roundabout.
I've seen the evidence first hand. I live near a somewhat busy intersection, especially in the summer*.
At one point, it was a simple stop sign. But about 20 years ago, they upgraded to a traffic light. And, a few years ago, they started converting it into a roundabout and have since completed it.
One of the roads parallels an interstate, and the section where the new roundabout is is where the interstate climbs a mountain (by Appalachian standards) so weather can be a bit dicy, fog has caused major pileups before, trucks go slow, vehicles catch on fire, etc. So, wrecks and other road hazards that cause the interstate to slow to a crawl or completely shutdown are a common occurrence. When that happens, drivers detour onto the road that goes through this new roundabout.
When it was a traffic light, traffic would always back up for miles as the intersection just couldn't handle the volume of cars of a modern interstate.
But now, with the roundabout, the backup is much smaller. Extending maybe half a mile. The intersection is still overwhelmed and can't handle the volume of a modern interstate, but the length of the backup is night and day.
So, yes, roundabouts are that much better at handling traffic flow compared to a traffic light.
*(There's a US highway with interstate exits in either direction, 2 National Park sites just 5 minutes away, and there's a state primary route with dozens of breweries, wineries, cideries, distilleries, and even meaderies. Not to mention the people who live in the area and commute through the intersection.)
Carmel Indiana doing the most. They are showing that we can in fact have safe roads in the US. It just takes effort to undo the damage they have caused.
If we truly wanted safer roads in the US we would make our drivers license examinations much harder similar to Finland's. It's just there are too many lobbyists and voters opposed to such restrictions
@@Mcfunface I totally agree. Getting a license should be way harder. It should also be a lot easier to revoke a license. If someone drinks and drives twice ever it should be permanent revocation imo.
I'm rural, about 35 minutes northwest of Carmel and my god do I absolutely love the roundabouts. I do most of my business in Carmel and anytime I have to drive somewhere else that doesn't have them it's enraging. Of course I hated them when I first moved up here, but that changes pretty quickly. Honestly, having fellow citizens that understand them is a major contributing factor; little bit of mutual trust makes them all the more seamless.
The nuances discussed regarding center diameter, angles, etc. are very important. There are some that have popped up in other places in the state and I don't think had the thoughtful engineering put into them that comes from having built hundreds, so are a touch sketchy. Glad they are spreading (even have a couple coming to my teeny town) and happy to see Carmel getting recognition; it's a lovely place.
And in other parts of the country, cities have been adding roundabouts on roads with median transit lines, especially light rail. In Salt Lake City, there’s one at the University of Utah campus. In the Phoenix area, there’s one in Mesa along Main Street, between the Mesa Dr and Stapley Dr stations, and the city of Phoenix is building a few more along south Central Ave. There’s even a roundabout built for a streetcar in downtown Tempe (Rio Salado Pkwy/Ash Ave). The advantage of roundabouts for those transit lines is that you can guarantee priority for transit vehicles, as with light rail, you can add railroad gates.
The most advantage of using roundabout: save lots of money for traffic light for traffic flow control and lots of time of waiting for drivers.
High Schools were designed like that but my high school wasn't, that is legit nice & fascinating ime.
Carmel is arguably the wealthiest town in the state, and the high school reflects it. I went to a nearby school, and students definitely had posters saying "your dad works for our dad"...
Good stuff about roundabouts! And good on the Mayor of Carmel!
As someone in Australia, I'm curious as to how the roundabouts here were "not up to snuff". I do know of some dodgy ones, come to think of it.
The old roundabouts didn’t have enough deflection on approaches.
@@petergreenson Thanks.
An intersection I have to go through quite often recently was converted into a roundabout a couple of years ago. I would frequently have to wait for no traffic or it would back up and I’d have to wait for a second cycle of the light. Especially when turning left from one of the roads. I’ve only had to wait a few seconds at a time since the conversion and most of that is because of drivers that don’t know how to use it. My horn has educated a couple of them.
So instead of your city fixing the intersection by installing sensored lights to replace the timed lights, you have to jam your brakes in front of drivers anyway informally? Doesn't sound like much of an improvement
Drunk AF & still up. Glad I caught this!
Lol same

Pure gold
@@Michael-ex9uoI dunno if Rob is on travel, but his native time zone is California / pacific. So if anything he probably worked on it all night and uploaded it before bed.
Thank you Mayor Brainard to have the vision for these.
Last summer we just had a modern roundabout built at Glendale Ave and York Rd in Niagara-on-the-Lake, Ontario Canada.
They have 2 slip lanes built in and once it opened up, the wait times are so little, even at a Friday afternoon rush hour, compared to the old traffic light.
Funny thing is at a lot of the intersections that don't see as much traffic narrower lanes and sharper corners would suffice to slow vehicles and it would be a lot cheaper. But because Carmel is so spread out from following the suburban development pattern for so long (even if they are trying to intensify their downtown) their focus is on keeping cars moving even in places where it doesn't make sense to spend that kind of money.
I am overjoyed you're finally taking a look at dumbbell roundabouts! I commented about that years ago. Excited for part two.
I live in Carmel. I think roundabouts are great specifically for a type of place that Carmel is. An affluent suburb with space to spare, money to burn, and a predictable amount of traffic flow. As Rob hints at for the next video, there are two north/south limited access highways that keep most thru traffic off of Carmel's streets. This leads to a predictable amount of traffic throughotu nearly all times of days.
In the suburbs, particularly when Carmel was growing, space doesn't cost much. But in dense urban centers, eminent domaining nearby parcels for a roundabout quickly adds up.
Finally, I think the pedestrian aspect on roundabouts, at least as Carmel does them, is mixed. In Indiana, pedestrians do not have the right of way until they STOP, look both ways, then cross unless they have an affirmative pedestrian signal. Which roundabouts lack. And because pedestrians are supposed to follow a roundabout with the flow of traffic, that could mean a pedestrian has to stop and yield up to 7 times in some of the figure 8 roundabouts.
It looked like the next video hint had him crossing 37 & greenfield, but he may be using that to illustrate the previous form of meridian/31 & keystone.
In Indiana pedestrians only have to yield to cars at unmarked crossings (jay walking) and signalized crossings, in unsignalized crosswalks (the kind at roundabouts) they do have the right of way and motorists are required to yield. This is actually why there are stop signs for pedestrians & cyclists on the monon, nickel plate & midlant trace trails; otherwise the cars would have to stop & yield to pedestrians and municipalities would have to clean/clear the sightlines for drivers.
With that rule, how are pedestrians supposed to cross the road in rush hour, when there's a nearly constant flow of traffic? In my country we have the same rule, and it sucks. Some drivers think we're supposed to step foot in the roadway to show our intentions, but that's uncomfortable and sometimes dangerous.
@@NewBuildmini The busiest road traffic in Carmel is often away from areas where pedestrians are common. But yes I've stood at the roundabout at US-31 and 116th and it can take a good long time for traffic to clear to make for a safe crossing.
In the more pedestrianized, urban core where Rob is for most of the video, there is a lot of courtesy stopping from drivers.
I love your stories, Rob. Speaking of roundabouts, we have a set of intersecting streets here in Colorado Springs, Colorado that has a statue in the middle of the road and it’s a big accident always happening. They finally are starting to talk about putting a roundabout in to solve a lot of the problem.
Very interesting video, looking forward to part two! Living in California, they were a bit late to the whole roundabout thing, but recently it's been getting more and more popular which helps with traffic flow and safety.
This Roundabout deep dive nails it! From their history to the true reason - saving lives. If anyone tells me that they "hate roundabouts", I'll share this video.
BTW, smaller roundabouts are a PITA for truckers. Getting around a roundabout and exiting in any direction means said truck must take up the whole width of the road. I drive 18 wheelers. I know. And I still love "roundys", to coin a nickname.
It may be prudent for truckers to go back to using the same sized trailers as Europe. They never increased their maximum length in part due to the amount of roundabouts.
Imagine getting a wind turbine blade around one they put on a bypass that was meant for truckers and oversized loads. They did that locally and now those loads are forced onto far a busier road, but in the next town over technically so the city that put it in doesn't have to deal with the consequences.
Some roundabouts have skirts to let truckers pass through.
Not sure if that is the official term: but a raised paved area around the circle that allows trailers to roll over top.
@@jamesphillips2285Roundabout apron
@@jamesphillips2285 This one does, but it isn't enough because the turn is way too tight. Most of the truck traffic now avoids it and has made a already busy through fare far worse or they go straight through downtown of this city which the bypass was design to stop that particular flow. In short the city did not think what they were doing through.
Down here in The Villages, Florida. About once a year a senior citizen goes straight through a round about at full speed, which sends their car into the air Dukes of Hazzard style.
The more you study all these roadway accidents, the more you realize most people simply should never be allowed to operate two tons of steel operating at high speeds. Cities need to return to walking and cycling as being the primary modes of transportation.
I never quite understood the general opposition present in the US against roundabouts. Although there are cases where traffic lights are a better fit (ex. a medium traffic load road perpendicularly crossing an extremely high traffic load road*) in most cases roundabouts are clearly superior by pretty much any metric.
* In that case, because people on the roundabout have right of way, the high traffic road would keep occupying the roundabout giving no space for the side road to drain, clogging that one up. And in such a case there's no easy way to build a (cheap) slip road either.
At the low end the same effect on traffic flow rate could be achieved with yield signs in place of stop signs, without any of the pedestrian benefits but in that use case they realistically aren't much different. Medium flow or high flow you have very specific use cases where they improve traffic flow but they can very easily get locked if a new development happens and traffic patterns change. My observation and experience has been in most cases they are a band aid for previous poor planning, or a vanity project and they have a short term placebo effect.
If you grew up in NJ and then moved to another state, that pretty much explains it. NJ would intersect highways with traffic circles, and it was literally a free for all. There was one particular circle intersecting Rt 70 and Rr 73 on Marlton that was both a circle and a regular intersection. It took NJ 4 or 5 decades, but they finally put an overpass in.
And NJ has this other oddity called jug handles. They are a way to turn left and come in two varieties. First, go past the intersection and loop back right onto the intersecting road. Second, turn right like an offramp before the intersection and turn left onto the intersecting road away from the main intersection. The first one kind of works. The second is just a disaster because you're still turning left but without the benefit of a light in many cases. So it becomes a dangerous free for all.
If you want to understand how to cause crashes with roundabouts, go to Oshkosh, WI, not having the experience with one. They use multilane configurations. You have to carefully watch the road signs and surface markings in order to be in the correct lane. Otherwise you'll end up side swiping other cars trying to exit the roundabout, especially during rush hour.
The only opposition I've personally encountered was from my grandparents. They had never seen a roundabout until their 70s when our city started building them. Stop signs and stop lights were familiar, but roundabouts were too new and chaotic.
If you have an extremely high traffic load road it should be grade separated and made into a highway rather than having traffic lights slowing down that high load of traffic.
@@major__kong Are those multilane configurations not standardized?
Great video! As someone who’s very familiar with Carmel's roundabouts (Moved here in 2021), I really appreciate the detailed history and educational background you provided. It’s fantastic to see how these roundabouts have positively impacted traffic safety in our city.
While I do have some critiques regarding Carmel's roundabouts being a bit too focused on speed and the throughput of cars, I want to highlight that roundabouts demand compliance from motorists, whereas traditional intersections technically only request it. Properly designed roundabouts are safer for everyone, not just motorists, by slowing down traffic and providing clearer, safer crossings for pedestrians and people on bikes.
Your video does a wonderful job showcasing the progress Carmel has made.
I knew I'd find you in the comments!
My biggest problem with round-abouts are not that they are inherently flawed, its that people are inherently stupid.
To quote Tommy Lee Jones; "a person is smart. People are dumb, panicky, dangerous animals, and you know it." We've gotten a few in the great state of Minnesota, and it boggles my mind how inept people are at traversing them. Was going through a major highway, old fart who shouldn't even have his license, was in the roundabout and slammed on the brakes to let someone enter the roundabout. He had no preconception that he had the right of way, he's not supposed to stop, hes supposed to keep going. This caused me to slam on my brakes, and get rear ended, because the traffic was too complex for someone else to understand.
And this isn't even taking into account that large vehicles such as semi trucks and buses have a difficult time navigating these roundabouts.
i mean what do you expect i never even driven on a roundabout either. seen one in Colorado once but that was about 10 years back there not even in schools books still i'm betting you
2 things: first, not all roundabouts are built to the same specs. I just had one built near me that requires 7 turns of the steering wheel to complete a straight passage. Second, roundabouts are a bad idea for snow plows and winter traffic in general. Carmel is fine, anything south of Kokomo is fine, building them in the lake effect snow band is stupid. They reduce accidents 9 months out the year and then double them the other 3 months.
It's crazy to me to think that the USAs first roundabout was built in the 90s. Here in the UK we have almost none of the typical American 4 way intersections, they are all roundabouts. Every single motorway junction has a roundabout or 2. They are just so so so much better.
The modern roundabout was developed in the late 1980s, modifying the antiquated traffic circles in Europe used for decades.
There is a "round about" here in Portland, OR; on Cesar E Chavez Blvd. And far as I know it has been there before I was born; 1975. The "round about" is NOT a yield sign, but a STOP sign; controlled area.
We have a Cesar E Chavez Blvd in Salt Lake City. Not the best area of town lol
The one on Glisan and 33rd(?) worked a lot better. Rode my bicycle through that one quite a bit when I lived there 20 years ago.
@@RoadGuyRob Correct; area. It's on 39th (renamed Cesar E Chavez Blvd (2009))
Begging to differ on the first roundabout thing: Just consulting Google Maps, I would get it if the road system on the D.C. side of the Arlington Memorial Bridge isn't maybe technically a roundabout, but it certainly functions as one, I think. Unless it's change in the several decades since I came upon it. I was a tourist from Canada doing touristy things, and had never used a roundabout before. I had a lot of trepidation when I saw the traffic flow signs on the bridge, but after getting through it I was "WHERE HAVE YOU BEEN ALL MY LIFE!" It's been a long wait, but roundabouts are making a welcomed appearance where I live now.
Great video Rob! I wish we had more roundabouts where I live (suburban Virginia Beach), I'm in the Air Force and have made several trip to the UK and I love their road network. Like you said you just keep moving rather than spending so much time sitting at traffic lights.
They replaced a traffic light with a 5 point, 2 lane roundabout here in Cheyenne WY in the last 10 years. I like it, though, it is a bit scary with it being a 2 lane and people not following the signs. Multiple occasions seeing people cut across a lane they are not allowed to in order to exit. For what it's worth I don't hear of many accidents regardless. That alone says something about the increased safety at roundabouts.
Last 10 years my community has been following suit as well, people still gripe about them but they do help .. just getting people to actually learn how to use them correctly is the trick.. I swear some people are stuck in their ways
When I was learning to driver, NJ had several "circles" that just worked. However with congestive and traffic growth, most were removed for Jug Handles and signals. Then those became congestive, so they tried bridges...talk about costly...then...circles or roundabouts have come back.
"I'll be the roundabout
The words will make you out and out
You spent the day your way
Call it morning driving through the sound
And in and out the valley" - Yes, 1971. I had to do it. Nobody else stepped up. I regret NOTHING.
One issue with rotaries with double lanes are drivers that refuse to stay in their lanes! The next issue are drivers that refuse to yield! The concept works with cooperation from all drivers. Thanks Rob. Delightful episode.
9:05 as an Aussie, that hurts my pride a little bit.
We're ripping way too many roundabouts out these days, I wish we could take a page out of Carmel's book
True, but as an Aussie who knows how arrogant Aussie engineers can be, it's kind of satisfying that someone who's had such a big impact on the US can takea big dump on them!
Australia are REMOVING roundabouts? That's a shame.
In fairness to AUS, he was talking about standards in 1998. Back when the U.S. had NO standards at all. I'm sure the designs have gotten much better over the years.
@@RoadGuyRob don't worry, we're still installing plenty of roundabouts! It's just that sometimes they outlive their usefulness under certain conditions. In some scenarios traffic lights can be a better option.
Roundabouts have a capacity limit. Once they reach that limit, they are no longer efficient. At that point they will have to install a signal.
@@traffic.engineer I have to disagree. Traffic lights operate better for about 2 hours out of every whole day. The rest of the time they cause unnecessary delays.
In every city in the United States, the hardest thing about building a roundabout is building the first one. People are so afraid of them until they drive on one, then they realize that they're much better.
I used to work overseas in the Middle East, and in Qatar, they used to have so many roundabouts! In the Middle East, you take your life in your hands driving on roads there, and roundabouts were common sites for fatal collisions. Eventually, the roundabouts were removed and replaced with traffic signals...which you didn't dare run the red lights on! The traffic deaths plummeted as a result...roundabouts work best on smaller roads like the ones pictured in Indiana, not 8 lane behemoths begging to become freeways.
I drive those rotaries in Cambridge all the time. They are a hot mess, and yet far superior to the lights up the road in each direction.
round abouts can be a huge pain for trucks tho. It can be very hard to merge into one when there isn't a chance for traffic to stop
I absolutely adore your implementation of BeamNG for crash sequences!
I didn't know there was a difference between Roundabouts and Traffic Circles. Oklahoma City has two of what must be traffic circles, there is a stop sign at every entrance and I think they are undersized to be useful. These are on NW 10th St. at the NW and NE corners of Saint Anthony's Hospital. The NW one works fine, it's easy to enter and get to your preferred exit, however there is not much traffic on this side.
The NE one is a different story. Not only is there a lot more traffic, as it connects to the hospitals main entrance and a lot of other businesses, mostly restaurants, on the streets around it, this side also has 5 streets conjoining at this spot. Since the traffic circles are already too small to handle heavy traffic the addition of a fifth street makes this one dangerous. In some places there is barely a car length between inlets/outlets and since you are coming out of a stop sign you must yield to traffic coming the opposite direction if you want to turn left. Since it's so small it's very hard to determine if another car is going to turn before your inlet which causes many people to hold at the stop sign longer than they should.
I've always thought these traffic circles needed to be larger but after watching this I think they need to also be turned into roundabouts. I always thought having to come to a stop before entering the circle was pointless and this video pretty much confirms that. If you're going to make people stop at a stop sign and yield to oncoming traffic before turning left you might as well just have a straight through intersection.
*Rob:* "Nobody's gonna just nail on the gas coming out of the first roundabout here when they see a block down the street there's a second roundabout, right?"
*Me:* _[Laughs in Motorcycle]_
i mean if that’s the way you wanna go out lmao….. i’ve seen high speed motorcycle accidents up close… wouldn’t be fun
raised crosswalk btw two roundabouts: [smiles and licks lips]
@@wyw876 Dood basically just designed a short track with moguls.
It's like he's never met a high school student driver? :P
Safer for drivers, but did I see un-signalled pedestrian crossings on dual-carriageways?!
Yes, but they're typically protected crossings with places to stop mid intersection. Though, some aren't wide enough for a bicycle.
American DOTs hate putting traffic lights at pedestrian crossings for some reason. It's weird because Canada has them everywhere without issues.
From the uk here (having over 10000 roundabouts), it nice to see the US start to take the roundabout in its pride! (Maybe even the ‘magic’ roundabouts lol)
Too bad you're still not in the Indy area, Rob. Right down the road in Beech Grove they just announced they're going to install a "peanut roundabout" and lots of people are up in arms about it LOL
I'm almost 100% certain he's going to discus those in the next video. The preview shows him crossing the intersection of SR37 & Greenfield. I'm betting he's going to show peanut roundabouts on the overpasess there on 37 and others on keystone.
Carmel is a nightmare to drive through. 96th street, just south, is the worst roundabout hell on Earth.
How so? Curious what trouble you've experienced on 96th.
@@RoadGuyRob It used to be a road that you could drive straight through. Little traffic, and the occasional stoplight when someone was coming onto the road from a side street.
Now, it's a constant series of chicanes, and the site lines are terrible. All for the five people per hour that turn onto 96th street.
Roundabouts have their place, but 96th street was a much better road prior to the roundabout obsession.
@@RoadGuyRob BTW, I love that you're such a road nerd that you asked me for more detail about a random road on the northside of Indy. You and Control City Freak need to collaborate on a project some time.
With each passing video Road Guy Rob takes another step towards full Orange pilled urbanist ;)
I grew up in Carmel. The hundreds of roundabouts have only helped with traffic. I remember when it used to take 20-30 minutes to cross the city. Now it takes half the time and feels safer by a large margin
Its a wild feeling where one of my favorite youtubers and the place i live collide...Im currently sitting less than half a mile from where this video was filmed!

Much easier to install a roundabout in new construction.
Retrofit projects have issues with property acquisition that may shift the roundabout toward a particular quadrant to avoid taking park lands, etc., which can create some nasty curves resulting in signs being knocked down repeatedly and landscaping demolished by trailers. Another problem with retrofits is that many intersections are on a hill. And those directly on a small hilltop create some interesting sight distance issues for drivers unfamiliar with the area. Of course you can install warning signs, but many drivers suffer from signing fatigue and simply tune out excess signage - the yellow ones in particular.
There are complex intersections, such as MO I-70 Exit 125, which has two roundabouts and a traffic signal, as there are access roads and exit ramps on both sides of the overpass. I think this example is especially challenging to drivers the first few times they go thru it. The dog bone at Mo I-70 and Range LIne Street, Exit 127, is also challenging, as its a two lane design, but I don't think its quite as bad as Exit 125. Both make me nervous enough to avoid whenever possible. Both are located in Columbia, MO, home of the Mizzou Tigers.
Personally, I think intersections on hills need roundabouts the most. Those intersections are often the most dangerous either way.
New Jersey use to be the Roundabout capital. When I was a kid, there were roundabouts everywhere. Then in the 70/80's they started to tear them out. There are still a few left but I remember the roundabout days.
Those are technically traffic circles, not roundabouts. They range from pretty efficient (like the one in Lakehurst) to pure chaos (the nightmare at 202 & 206 in Somerville)
Not the same. Those are traffic circles, not roundabouts. Roundabouts are like what you see here in the video.
Traffic circles are much smaller in diameter, and not at all the same as a roundabout. Here in my Orange County (CA) neighborhood, there are several traffic circles, but if you hit the right angle, you don't even need to slow down while going through them. It's basically just a yield sign.
Rob, a city I would love for you to do is Savannah somebody's comment made me think about it, but you should do a video on Savannah squares. Which work as a traffic calming measure themselves.
I've never heard of a Savannah square. Will have to check it out.
I could watch endless videos on Carmel Indiana
Traffic lights turn cars into "pods" and round-a-bouts keep them nicely spaced
they sure do - the technical term is a Platoon by the way - for your next pub quiz :)
Rob your channel is brilliant. I love how you combine video footage with descriptive graphics to get your point across.
Always nice to see a place embrace roundabouts (tho I don't necessarily think they belong in every intersection), just wish it didn't require essentially tricking people into putting them there in the first place..
They needed to be tricked because they were too stubborn to see sense
@@marklittle8805 Ik, and I wish it wasn't that way -.-
I used to hate roundabouts. Coming from NY where people didn't know how to use them, people would just blindly blow through them thinking "no stop sign, I can go". I moved to Carmel in 2020, after watching the city grow over 15 years (wife's family is from here). I now like the roundabouts and appreciate them. Approaching the intersection to exiting has never been more than minute and, more often than not, just barely a pause before entering. When traveling outside of Carmel and I get to a red light with no cross traffic, I wonder "why isn't this a roundabout?"
Traffic Circles are nice, until you get to a point of chaining multiple right off the highway. If you happen to be cruising on I-75 in Ohio, take Exit 181 into Bowling Green. We be making chains out of traffic circles
I used to live in Carmel,and now I live in Fishers next door. The roundabouts are spreading, but for low-capacity intersections, they are absolutely wonderful 95% of the time. Any time there is a large number of cars going through, my 20-min commute to Carmel for work turns to 40 minutes. Timing versus traffic is the true key to using them around here.
And Brainard, while no longer in office, loved to talk about these roundabouts with anyone he can. He slao helped to revitalize downtown Carmel to a place better than downtownm Indy.
Roundabouts are great in low to medium constant flow traffic areas but once you get to high traffic flow or have inconsistent traffic flow, they become nightmares to traverse. Another thing to think about is traffic lights also give pauses in traffic that allow people to turn out of parking areas or streets. So no roundabouts are not magical wonders but they do give city planners another tool to manage traffic.
side note: the point of roundabouts is to keep traffic moving but once vehicles have to stop, for whatever that reason maybe, it defeats the purpose of a roundabout. Also some roundabouts are pita to cross for larger vehicles such as school buses.
Awesome video Rob! As an American driver living in Europe now, I *love* roundabouts. They are so much more efficient and better than 4-way stops (especially) and traffic light intersections! That's why I made a video about them on my channel a couple years ago...they're just great!
I was first confronted with roundabouts 60 years ago in England and Ireland. My first reaction was it’s a crazy way to drive. After negotiating my first three or four I realized how efficient and safe roundabouts can be.
I’m 100% in favor of roundabouts!!!
Love your videos man, keep up the energy
Our high school in Shakopee, MN needs like FOUR roundabouts. The intersection I use every day leaving my neighborhood has people across from me departing the high school 24-7-365. SO frustrating.
damn that outro got me all pumped up haha
Mission accomplished 😃
(I worked in radio forever, so a punchy promo to get a listener to stay tuned is right up my alley!)
Rob, I grew up in Cherry Hill, NJ, where we had a number of traffic circles, all built in the 50’s and 60’s, I believe. Elisburg Circle, Racetrack Circle, Airport circle… and countless others, all along the length of our state highways through the greater Cherry Hill region. (70, 73, 38, 30, 130) All of them were intact when I started driving in 1987 and I loved them. But over the years most of them were destroyed by traffic engineers attempting to address capacity concerns. Some received signals, others were cut in half. Every attempt failed and now all or most of them are gone.
OF NOTE: I am told that Route 30, which crosses the USA from the Jersey shore to the other coast out left somewhere (Cali, Oregon, Washington? Who can say) used to have a traffic circle at both ends.
We moved to southern West Virginia 16 years ago, and every time we go back to visit family, it makes me sad to see the monstrosities that replaced my beloved circles over the years. They were ahead of their time.
90% reduction in traffic accidents? Its bizarre that not every single intersection in the country is not being converted now…
The benefit is on low volume roads that do not meet signal warrants. They are innefficient on high-volume roads.
