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.
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
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.
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.
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!
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.
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
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
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.
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.
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.
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.
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.
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!
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.
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.
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.
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.
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!
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.
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.
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.
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.
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.
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.
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
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.
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.
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.
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.
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.
*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]_
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.
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.)
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.
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.
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.
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.
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.
@@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.
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.
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!
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.
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.
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.
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
Hey Rob, I've got an idea for a future video for you! Rumble Strips!! I don't know why but ever since I've been a kid, I've been kinda fascinated with them... and I'm not just talking about the ones on the shoulders... I'm talking about Transverse Rumble Strips. The ones that go across lanes. Minnesota had a study done on the effectiveness, and they do help reduce crashes at stop lights and/or stop signs. But it's mainly in rural areas they use them, because the rural areas here in MN are the areas where crashes at intersections due to someone not stopping have higher fatality rates. Rumble strips are kinda controversial but they are an effective device! Would be cool to see you investigate them and talk about them!
There aren't a lot of good things I have to say about Carmel, I work there M-F and then leave... happily. But the roundabouts... They mostly nailed them. Driving in Carmel is generally great. Although the roundabouts that were added to the rework on US 31, turning it into an interstate-class highway, with peanut roundabouts underneath... Those struggle at peak times.
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.
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
1:33 “but a roundabout, you have to slow down for those” No, I’ve seen idiots speed right through them ignoring those already in flow, completely stop when completely unnecessary, and the entire gambit in between.
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
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"...
Great vid Rob! Yeah, there’s a few roundabouts in back-roads Florida that can cause mile-long backups in rush hour because they’re so tight; ugh! Those tight circles aren’t semi-truck friendly! Suddenly, I feel compelled to play some ‘70’s Yes music! Thanks again Rob!
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.
The one thing that always confuses the discussion when non-US folks look at our roundabouts is the YIELD on entry. My understanding is that European roundabouts require drivers to switch lanes inside the roundabout to exit, and therefore, if the outer lane of the roundabout is empty, you can merge in. US roundabout DO NOT WORK that way. US roundabouts "lock the driver in" to an exit when they enter--there is no changing lanes inside a US roundabout. And the flip side is that instead of attempting to determine if the vehicle in the roundabout is going to change lanes to exit so is it safe to enter?--you simply yield to ALL LANES when entering.
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.
Living in the Indianapolis area since 1991, with Carmel being the area where I drive nearly 50% of the time, the roundabouts work very well. One of the nice things about them is that you can easily pass slowpokes on two lane roundabouts.
@@mikebronicki8264 occasionally it’s the people going 5 to 10 under the limit. Most often it’s the clueless people who come to a full stop before entering the roundabout, even when there is no one around.
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!
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.
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.
That drone collision. Been there. Glad I'm not the only one -- ironically, I was thinking "What a beautiful drone shot" as we went around the flower, "I wonder if that's stock footage..." and then got my answer. lol. Great video.
I drove hours out of my way on a multiple day trip last week just to try out the roundabouts in Carmel, IN. It was awesome and there is a stark and disappointing change as you pass into the stop signs and traffic lights of neighbouring towns.
I've also noticed more roundabouts popping up in my home state of Florida and when I was in Las Vegas in 2022, I noticed many roundabouts so it's good to know the inception of the concept for the US kind of originated there!
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.

I love roundabouts. Great to hear how well they've done in Carmel.
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😀

@@MonkeyJedi99in and around the lake
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.
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.
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.
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!)
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.
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
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 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
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.
Im from Malaysia but I love watching your video! It have that mid 2000s american tv show vibe!
Yeah your right it does feel like watch a 2000s PBS Documentary
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.
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.
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.
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.
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!
It's so strange seeing "shark teeth" on the road in the USA. I'm so used to seeing them here in The Netherlands.
funny swamp
@@longiusaescius2537get outta my swamp!
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.
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.
Indy did? I thought they were staunchly against roundabouts?
@@evancombs5159 They're coming around to it. lol slowly but surely.
@@cortburris9526 at least they know to drive in circles in Indianapolis ;)

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.
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.
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
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.
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 absolutely adore your implementation of BeamNG for crash sequences!
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.
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.
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))
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.
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
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
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.
Road Guy Rob visited my county!
Also Keystone and SR-37 need the round-a-bouts.
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.
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.
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.
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
*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
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.
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.)
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.
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.
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.
Hey where you're in Indiana you got to check out the red line and purple line brt in Indianapolis too
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.
I am overjoyed you're finally taking a look at dumbbell roundabouts! I commented about that years ago. Excited for part two.
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.

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.
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!
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!
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.
Awesome video. I love roundabouts too! Next best thing If I can't have proper public transport!
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 your channel is brilliant. I love how you combine video footage with descriptive graphics to get your point across.
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
6:15 Those two Cambridge rotaries by Fresh Pond are kinda terrifying. Traffic there is always totally snarled up during rush hour.
Round about done right. Amazing. I have a story about it down absolutely wrong
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!)
Hey Rob, I've got an idea for a future video for you! Rumble Strips!! I don't know why but ever since I've been a kid, I've been kinda fascinated with them... and I'm not just talking about the ones on the shoulders... I'm talking about Transverse Rumble Strips. The ones that go across lanes. Minnesota had a study done on the effectiveness, and they do help reduce crashes at stop lights and/or stop signs. But it's mainly in rural areas they use them, because the rural areas here in MN are the areas where crashes at intersections due to someone not stopping have higher fatality rates.
Rumble strips are kinda controversial but they are an effective device! Would be cool to see you investigate them and talk about them!
There aren't a lot of good things I have to say about Carmel, I work there M-F and then leave... happily. But the roundabouts... They mostly nailed them. Driving in Carmel is generally great.
Although the roundabouts that were added to the rework on US 31, turning it into an interstate-class highway, with peanut roundabouts underneath... Those struggle at peak times.
I freaking love this video!! And roundabouts!
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.
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
Love your videos man, keep up the energy
1:33 “but a roundabout, you have to slow down for those” No, I’ve seen idiots speed right through them ignoring those already in flow, completely stop when completely unnecessary, and the entire gambit in between.
Excited your doing this series, in indiana! My state. So fascinating! Thank yiu!
It's really amazing how over and over people prove that they don't know what they really want and they don't know what's good for them.
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
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"...
In some of the towns traffic moves like a ball through a pachinko machine. Enough with the roundabouts already.
Look forward to your video on the Keystone Parkway
Great vid Rob! Yeah, there’s a few roundabouts in back-roads Florida that can cause mile-long backups in rush hour because they’re so tight; ugh! Those tight circles aren’t semi-truck friendly! Suddenly, I feel compelled to play some ‘70’s Yes music! Thanks again Rob!
Very cool graphics now, good work with this one!
With each passing video Road Guy Rob takes another step towards full Orange pilled urbanist ;)
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.
The one thing that always confuses the discussion when non-US folks look at our roundabouts is the YIELD on entry. My understanding is that European roundabouts require drivers to switch lanes inside the roundabout to exit, and therefore, if the outer lane of the roundabout is empty, you can merge in. US roundabout DO NOT WORK that way. US roundabouts "lock the driver in" to an exit when they enter--there is no changing lanes inside a US roundabout. And the flip side is that instead of attempting to determine if the vehicle in the roundabout is going to change lanes to exit so is it safe to enter?--you simply yield to ALL LANES when entering.
I love round abouts. Its basically a chicane so i can apex the corner late and launch myself out with maximum cornering speed 🤣
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 could watch endless videos on Carmel Indiana
Living in the Indianapolis area since 1991, with Carmel being the area where I drive nearly 50% of the time, the roundabouts work very well.
One of the nice things about them is that you can easily pass slowpokes on two lane roundabouts.
Easily, until you hit one. And some people consider doing 30 in a 30 as a "slowpoke."
@@mikebronicki8264 occasionally it’s the people going 5 to 10 under the limit. Most often it’s the clueless people who come to a full stop before entering the roundabout, even when there is no one around.
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!
My favorite channel. Thank you Mr. Rob.
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.
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.
That drone collision. Been there. Glad I'm not the only one -- ironically, I was thinking "What a beautiful drone shot" as we went around the flower, "I wonder if that's stock footage..." and then got my answer. lol. Great video.
Fascinating stuff!
I drove hours out of my way on a multiple day trip last week just to try out the roundabouts in Carmel, IN. It was awesome and there is a stark and disappointing change as you pass into the stop signs and traffic lights of neighbouring towns.
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.
Here in Phoenix, AZ people don’t know how to use them 😂.
I've also noticed more roundabouts popping up in my home state of Florida and when I was in Las Vegas in 2022, I noticed many roundabouts so it's good to know the inception of the concept for the US kind of originated there!
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.
