Traditionally, a highway isn't even a particular road... It is a route often including multiple different roads. The US has limited.access freeways, of course. But we do a pretty poor job at that thing between a street with direct access to places and freeways.
@@flinx There may be a difference in how we call our roads and I just felt the need to point it out since it sounded so weird to me. In Poland highways and expressways are basically the same thing, the former having a speed limit of 140 kph and the latter of 120 kph. Both usually lead around and not through cities. They always have hard shoulders (except for the older parts of the motorways) and never have any at-grade intersections,. There are only interchanges that can only be stituated a few kilometers apart (further apart in the coutryside and closer together near cities, additionally the expressways have shorter required spacings than motorways have). Their begining and end is always marked by a special sign, as in all of Europe. The expressways also differ very slightly in the width of lanes and hard shoulders, which are narrower, they can also have one lane in each direction in some cases (it's rather rare and the speed limit is changed to 100 kph then, as there isn't usually a median in that case). Other than those we have national roads, which are state-maintained, but are almost always single-lane with no median, although there are exceptions and the speed limit is then raised to 100 kph, as opposed to the usual 90 kph. They often lead through the centers of towns and villages or even cities, where the speed limit is 50 kph, as they are usually built-up areas, that is however often not obeyed by the drivers in smaller towns without speed cameras. Voivodeship roads function similarly to national roads, although they are maintained by the voivodeships. Medians and higher amounts of lanes are even rarer on them (with some notable exceptions, like the DTŚ in Upper Silesia).
Indianapolis has warmed up to modern roundabouts and have been replacing stops with roundabouts. I live near on on the far west side. Also, the other Indy suburbs have been adding massive amounts of roundabouts. Also, the state of Indiana has been building them on some state highways.
The Carmel mayor was basically the first importer of roundabouts, before there were even federal guidelines on how to build them. Indianapolis, and so many cities after him have been building them because the federal traffic guidelines strongly recommend them, and they are far cheaper than installing traffic signals.
Traffic lights are a big failure because 60% of people drive like theres an acceleration speed limit and take 4 business days to piddle up to speed. Once you factor this annoying behaviour in traffic lights move even less traffic than they do on paper and ultimately people warm up to roundabouts after initial hesitation because they realize they hated sitting at lights way more
@@P7777-u7r There is an American Couple spending a few years in the UK with the armed forces (Daydreamers Barn) and their latest video (in the Peak District) they said they are going to miss the roundabouts when they go back to the US. Maybe they will end up somewhere where they are being built so will not miss them as much.
The roundabout phobia is a real problem that we need to cure. I love driving in Carmel and would like to see roundabouts in more cities I drive in. Just one hundred and forty miles to the north of Carmel in my hometown where I grew up the state wanted to remove an interchange at the junction of two state highways and replace it with a roundabout. The public opinion was totally against the roundabout, so the state is building a grade intersection with Michigan left turns. I see that as a nightmare. The state gets rid of the cost of the bridges, and the automobile insurance companies get the cost of accidents in the unsafe Michigan Left Turn intersection.
It is, the cure to this is to start small. Find a 4-way stop and replace it with a roundabout. Also, your hometown is going to hate the Michigan Left Turn even more. The one at 96th and Allisonville rd is hated by everyone. I think it may have been a failed experiment as they've been doing construction on it already despite the pavement being in good shape.
Roundabout addiction is a real problem. We have too many roundabouts being put in without proper design with regards to things like visibility and heavy truck traffic. All for a realistically marginal increase in traffic flow and increase in accidents.
Here in Phoenix, people have no idea how to use them. Folks will just stop in the middle of the roundabout to try to let someone in not realizing that the traffic that's in the traffic circle has the right of way.
Been traveling that section of Keystone for almost 30yrs now. These roundabouts were a huge God send. Complete night and day difference. Every where I have been throughout Indianapolis (Marion County) that has put in roundabouts, the traffic moves much more consistent and fluidly... .. minus the handful of people that just can't wrap their heads around them and use them like stops.
10:30 this bit of psychology is pretty interesting because the same thing tricks people into thinking that bike and bus lanes are useless they dont see anyone queued up in them(because theyre free flowing) so it looks like there isnt anyone using it
In the Netherlands there are a lot of intersections with a lot of lanes that only exist around the intersection. The biggest example I know are three light-controlled roundabouts on N220, N223 and N213 which are all less than a mile apart from each other. In one case there's just one lane that turns into five lanes before the intersection (1 left, 3 straight on, 1 right). Then between two intersections (about 2,000ft apart) the three lanes continue and turn into seven lanes (2 right, 2 straight on, 3 right). And if you continue to go straight on, the two lanes just turn into a single one again. All that capacity is necessary, because most of this area is covered by greenhouses, which are very important for the Dutch economy, so there's a lot of freight traffic in this area
Thanks Rob for doing a video series in my area. The roundabouts and construction in the Fishers, Noblesville, Carmel area for the past decades are paying off. Thanks again Rob!
I couldn't afford to stay in Carmel. My cheaper hotel was up toward Westfield/Fishers/Noblesville. If I ever moved there, I likewise couldn't afford Carmel, but would look at that area (not planning to move there, but if I did...)
The real solution would be a single commuter lane walled off from the rest of the road that never stops, but local businesses despise them for bypassing their stores and they can be expensive to build (due to the necessary overpasses/underpasses to be built for cross traffic to pass over.
I’ve learned way more about how Roundabouts are better than red lights in these two videos alone than I ever did. Normally the red light intersections i’ve been in are not in congested areas so I’ve not had to think about the logistics too much.
Rob, I've been watching your videos for a while. I used to wonder if you'd come to the Midwest, but now you've made multiple videos right by and about my home town! Nobody else makes great road content the way you do. Keep up the great work!
I truly believe you have the best channel on all of TH-cam. The quality, the concepts, and your personality all make this such an amazing watch each and every time. Great work!
Awesome to see a mayor willing to go through a jurisdictional transfer. Its' really frustrating that the city where I work we have great ideas for state routes, but no one seems to want to pull the trigger and have that discussion. So we keep pointing the finger at who's to blame when it comes to fatal crashes and design. Well done Carmel!
A strong part of the solution is the grade separation of the busy highway from the rest of the intersection. As most of the traffic is moving straight, it does indeed make little sense to stop everyone from moving just to open up for a little cross traffic. Instead, with the through traffic eliminated, all the low-speed traffic and pedestrians can coalesce up in the barbell.
That's because people there are uncivilised. Come on a trip to Europe and rent a car anywhere and you'll see how much better not having stopsigns is. I come across 4 or 5 in my 30 min commute and it's already almost too annoying.
I used to not be a fan of roundabouts, but I now am. People still drive through them too fast, and some are a bit tight for my semi truck. Crossing as a pedestrian or cyclist can be sketchy at a time's. Even with the flashing pedestrian lights, drivers don't always stop.
Awesome video as always Rob! When that lady asked if you were with the news, you should have answered "much more useful, educational videos on TH-cam". We appreciate you man.
@@RoadGuyRobI dunno if it's intentional or not, but you nail the reporter "accent", if that makes sense. It's actually a huge reason that I love your videos though I have no idea why.
Driving up Keystone/37 in Carmel is awesome for everyone. My Doctor is one intersection north of where the roundabouts and 37 going under ends. Traffic is slower there and no sidewalks. It is jarring. Taking a strode under the cross streets seems simple, but is genius. The Carmel/Fishers area is booming because of this and other things. I would surmise that the GDP increase more than covers the costs for an infrastructure project like this.
I recognized this Rob. They did the same thing on Hwy 41 and 141 (Underpass triple roundabout) and Hwy 41 and 32 (triple roundabout overpass) in Green Bay, WI.
I am always trying to educate people in my community how we can avoid building wide roads if we use roundabouts instead of traffic lights. Thank you so much for making this excellent video that explains why!
For an upcoming project one of my city engineers touted the benefits to local traffic, citing platoons. They will have more opportunities to turn out of their neighborhood since the cross traffic will be "better distributed into platoons" and I knew what he meant thanks to this TH-cam channel. Good work, Rob!
Here before someone comments "90% of all planners quit one lane before fixing traffic forever". But yeah it is a good thing that we recognize that road widening doesn't actually fix traffic, it just accommodates more cars. The way to fix traffic is to find ways to make best use of the road space that is available, instead of just widening.
Yes, but also making it easier for people NOT to drive is an important part of what Carmel did - allowing for more biking and walking. For bigger cities, investing in public transportation would be necessary. Most trips in the US are short and don't require cars, even in the suburbs. If we designed cities for people, not cars, we'd get a lot less traffic.
@@louiszhang3050 Yeah and cars use a huge ton of space. There is a reason in the olden days not everyone in the city owned a horse. Not that we don't want cars at all, we just want fewer of them, and we want there to be options for those in the city. People in the countryside may always have to drive, and that's fine, but for people in a city a car is a hassle. People may commute to work by car still, but for shorter trips, if those options are available, they will probably walk, cycle, or take public transit, and the few times they will need a car, they will face decreased traffic congestion and less aggressive drivers.
And alternatives to driving so not everyone needs a massive rolling living room to do anything. The people who just wanna go to the store close by can just take a bicycle and get some exercise in while they're at it.
As an Aussie who grew up just across the tracks from Canberra/ACT - roundabouts made walking my 60kph/37mph residential home streets to/from school (that often had busses going up/down them) safe and comfortable, whilst also allowing the traffic on the main road through town flow smoothly to peal-and-pack at like 80kph/50mph once outside the residential and semi-residential areas. What Memorial Circle was was a (Controlled) Traffic Circle and not a proper Roundabout due to the stop-start nature of the signaled segments it was built with, whilst proper Roundabouts are at-worst a Give Way intersection (though it seems Americans don't know how to use those from what I've seen and read) in terms of traffic control.
We Australians call Give Way the Americans call Yield. Roundabouts work better in Australia because of our "give way to the right" rule which maps into roundabouts. Americans also have "give way to the right" at intersections but roundabouts would need "give way to the left" for the same effect.
Oh and I used to live near the worst intersection in Queensland (corner of Albert St and Station Rd, Bethania) according to RACQ. There was a mix of Give Way and Stop signs and no one could read it. I wish they replaced it with a large roundabout but instead they installed a stupid set of traffic lights. It's ridiculous for a relatively quiet intersection to have to wait 5 minutes at an empty red light!
@@lztx Americans have a "first come, first served" rule. "Priority to the right" is a thing only in some states, and it generally only applies when multiple vehicles arrive at the same time.
Rob, I have been watching your content for a couple months, and I've thoroughly enjoyed it and learned a lot! I was blown away when I realized you don't have a million subscribers. I just watched your video from three years ago about highway on ramp traffic lights in California, and it has all the same style, content, and humor that your new stuff does. I think youre going to just explode one of these days. I wish you all the best, and will be sharing your stuff with friends. Keep it up!
I live on the far north side of Indianapolis, just a few blocks south of Carmel. I love what Jim Brainard did there. It took real vision. It's such a nice place to be. Now, the downside of Carmel is it's very expensive (for Indiana) and not very diverse. Carmel is kind of a playground for the rich, but there's no reason a real city like Indianapolis couldn't be at least as urban as Carmel. I can't believe my city sued to prevent roundabouts. There's so much evidence that they're safer and make traffic flow better. I drive on 96th Street fairly regularly these days, and the roundabouts are great.
Grade separation is so incredibly powerful its why we still have minimum spec 2 lane freeways in some very busy cities. yeah they back up, but once the bottleneck is cleared the rest of the freeway clears fast. Unfortunately grade separation is deeply unpopular in urbanist circles, most are just hoping that the efficiency of transit and bikes can make up for the inefficiency of traffic lights.
0:45 Sorry Rob but that title belongs to my home city Saint-Herblain in the suburb of Nantes, Western France (which is technically in the western hemisphere). We have 180 roundabouts for a population of only 50000. Stop signs and traffic lights are a rarity here.
Great video, you touched on a lot of different topics in the engineering world that I had not heard of before. Platoons? Such a cute name for something so inefficient!
4:20 : Coors is an interesting place I’ll just put it at that. Coors traffic is mostly from Paseo Del Norte people, and when Paseo is blocked it usually doesn’t take all that long. When I drive down coors to go somewhere it’s usually not too bad. It’s only when people get off work around 7:00 PM when it starts to get bad. Also the fact that it is 45 through that part is let’s just say … Interesting.
This was a really great video dude! Follow a lot of urbanist youtubers and roundabouts aren't a huge topic so these videos have been really great to watch. I would have loved to see more of the simulation and also would have liked to know what happened to all of the $100 million, if the roundabout bridge was only a fraction of that. Imagine being a mayor that said, "Oh hey btw I just made our city $80+ million."
We had a traffic circles ("roundabouts") in north Phoenix at Happy Valley Rd. on either side of the I-=17 freeway. During rush hours, one direction of traffic dominated control of the circle, blocking all other directions. A few years ago, the roundabouts were replaced with a Divergent Diamond Interchange, and traffic moves much more smoothly now (although there are a couple of intersections to the frontage roads that have long-wait lights.
Lived in Fishers for three years and drove thru Carmel regularly. SR 37 from 116th northward in Fishers looks quite nice now (well, once they finish 37/141st that is...) but US 31 & Keystone in Carmel are wonderful drives.
The dumbbell (I believe that is the 'official' term) roundabout is a brilliant idea (if it is designed like 9:41), not only it is cheaper it is also safer than oval roundabout. Oval roundabout is quite dangerous because cars could accelerate at the two bridges because they are in straight lines (like in 9:31) so there are two potential high speed collisions at the roundabout.
10:19 this is so true. This entire video gives so much great insight and I feel like everyone in civil engineering should watch these (and the politicians that control the decisions made by the DOT). We could make our roads so much more safe, efficient, and pleasant for ALL users, not just cars, if we started doing things like this. And the new highway in Carmel looks so much more aesthetically pleasing.
Just south of Indy on SR 37, it's getting upgraded to I-69, and every single new interchange is a roundabout (including a peanut shaped one right near me). I'd never seen a roundabout interchange before and was wondering how INDOT knew they'd work so well, and this seems to be the answer! Thanks RGR!
As a resident of Indy, the Indy gov needs to get over themselves and build more roundabouts. I would love to have them. I think the north side anyway would appreciate them. The only people who don’t like them are ones who encounter them infrequently.
Rob, you made a critical point, and that is that overpasses can actually improve the quality of life. NY Route 347 could have had a plan like this, but NYSDOT caved in to pressure to create an urban boulevard, rather than use a modified freeway. Our group urged NYSDOT to rethink its plan by adopting what we called a greenway approach using overpasses similar to those on NY parkways. NYSDOT did take on the idea of using overpasses and instead widened the road to three lanes, and widened intersections to accommodate two left turning lanes in each direction. An opportunity missed due to anti-highway hysteria.
I know it’s expensive for them to do these roundabouts, but it’s like the interstates, it’s expensive to do it the first time but then it’s just maintenance from then on.
Rob, this has been a great series so far, I absolutely love this stuff! Next time I'm passing through Indiana I'm going to make my way to Carmel just to see all this great stuff in action.
If you think about it, a traffic light basicly cuts the time at which traffic can pass down to a bit below 50% (if traffic in both directions is similar). So to keep the same amount of traffic passing the lights as the road can handle, you'ld need more than double the lanes at the intersection. So a two lane road, would need 5 lanes at the traffic light. After the light it can go back to two lanes.
Valparaiso, Indiana did something very similar with Indiana State Rd 49 at Vale Park Rd on a smaller scale, and it definitely helps with traffic flow and you frequently see people walking or biking over the freeway bridge and across the roundabouts. I hope the city eventually does the same thing at the two busy intersections north of it and the busy intersection at LaPorte Rd/Indiana SR-2 as well.
Your videos are worth the wait!! Do I wish you posted every few days and had this same quality and time on each? YUP! But that would take a big team and you doing nothing but reading scripts while your team does editing, camera, and scripts. lol... Your research for every video is awesome and the way you explain everything is great. I've always been facinated with roads and roadway engineering since I was a kid. I just had no idea how to get into that industry.
I drove Lyft in Indianapolis for 5 years, the biggest issue I ever had with the roundabouts in Hamilton county was almost getting hit by people who had no idea how they worked. I have had at least 15 separate incidents of grandmas driving the wrong way in the roundabout and almost hitting me head on
As a pedestrian I hate Roundabouts (especially with no proper sidewalk crossings) As a cyclist I hate roundabouts (people never notice you, or try to overtake you in the circle) As a motorist I love roundabouts. As a part time Bus driver I hate roundabouts, especially multiple lane ones when you need to go to the inner lane to make an exit.
we've got a peanut roundabout over an interstate here too! now i know why they chose the peanut shape. thanks! (our new diverging diamond totally sucks tho. just as slow as before. they are planning on making a bunch of other modifications.)
Thanks for making this video and explaining it so clearly. I mean this just describes city driving to a T. Half of the road is full, half is empty, half of your trip is moving, half is stopped in a parking lot at a red light. Making more lanes when you don't or can't fix the obstructions to the flow is just making bigger parking lots at bigger and more complex traffic lights that they program to stay red longer and longer. The conversations around the width of the roads just pits people against each other when the "solution" doesn't even work (except if you happen to own a road construction company).
An interesting topic I would recommend is what North Texas has been doing to some of the traffic heavy junctions to improve flow. Check out the junction of Texas 635 and 121, how going east bound, 121 splits into two roads, the right road where the ramp from 625 joins, then the right road splits again with the left half going north, and the right half travelling around the second junction to rejoin 121. At first it seemed like it would be a nightmare, but it made merging from 635 to 121 so safe and simple. Before, you'd have to fight people trying to leave 121, to go North, if you were coming from 635 trying to get on 121, to go East.
Yeah. Around here, all of the permanent span wire signals are old, and they don’t do much with long-term temporary signals (they even have a portable signal at an intersection in place of the mast arm that got knocked out by a truck, and have no plans of fixing it). I honestly wish they still installed them. with the kind of wind we get here (can get pretty strong, but not hurricane level), they can actually be better if done right. The lower anchor wire is definitely essential (otherwise, the electrical wires will get bent around and break).
Indianapolis hating traffic circles seems ironic given ‘cars driving round a left turning oval’ is their whole thing.
Biggest export is irony

As a Pole it blows my mind that a road with traffic lights and at-grade intersections can be called a highway or an expressway.
Well if those traffic lights weren't there you'd be out of a job!
Does Poland have freeways as a separate category from highways? Or are Polish highways what Americans call freeways?
Interstates must be grade separated, but US/State/County Routes (also sometimes called Highways) can be at-grade.
Traditionally, a highway isn't even a particular road... It is a route often including multiple different roads.
The US has limited.access freeways, of course. But we do a pretty poor job at that thing between a street with direct access to places and freeways.

Other than those we have national roads, which are state-maintained, but are almost always single-lane with no median, although there are exceptions and the speed limit is then raised to 100 kph, as opposed to the usual 90 kph. They often lead through the centers of towns and villages or even cities, where the speed limit is 50 kph, as they are usually built-up areas, that is however often not obeyed by the drivers in smaller towns without speed cameras.
Voivodeship roads function similarly to national roads, although they are maintained by the voivodeships. Medians and higher amounts of lanes are even rarer on them (with some notable exceptions, like the DTŚ in Upper Silesia).
Indianapolis has warmed up to modern roundabouts and have been replacing stops with roundabouts. I live near on on the far west side. Also, the other Indy suburbs have been adding massive amounts of roundabouts. Also, the state of Indiana has been building them on some state highways.
Crazy what one mayor can do, he started a chain of events of roundabouts
The Carmel mayor was basically the first importer of roundabouts, before there were even federal guidelines on how to build them. Indianapolis, and so many cities after him have been building them because the federal traffic guidelines strongly recommend them, and they are far cheaper than installing traffic signals.
Traffic lights are a big failure because 60% of people drive like theres an acceleration speed limit and take 4 business days to piddle up to speed. Once you factor this annoying behaviour in traffic lights move even less traffic than they do on paper and ultimately people warm up to roundabouts after initial hesitation because they realize they hated sitting at lights way more
@@coherentpanda7115 They still work when the power goes out 😉
@@P7777-u7r There is an American Couple spending a few years in the UK with the armed forces (Daydreamers Barn) and their latest video (in the Peak District) they said they are going to miss the roundabouts when they go back to the US. Maybe they will end up somewhere where they are being built so will not miss them as much.
Thanks for keeping the public informed on infrastructure!
Happy to! And thanks for your support, @XxXenosxX! (Hope I types that right! A lot of Xs!)
The roundabout phobia is a real problem that we need to cure. I love driving in Carmel and would like to see roundabouts in more cities I drive in. Just one hundred and forty miles to the north of Carmel in my hometown where I grew up the state wanted to remove an interchange at the junction of two state highways and replace it with a roundabout. The public opinion was totally against the roundabout, so the state is building a grade intersection with Michigan left turns. I see that as a nightmare. The state gets rid of the cost of the bridges, and the automobile insurance companies get the cost of accidents in the unsafe Michigan Left Turn intersection.
I know what you’re talking about! The U.S. 12/M-51 intersection in Niles…
It is, the cure to this is to start small. Find a 4-way stop and replace it with a roundabout.
Also, your hometown is going to hate the Michigan Left Turn even more. The one at 96th and Allisonville rd is hated by everyone. I think it may have been a failed experiment as they've been doing construction on it already despite the pavement being in good shape.
Roundabout addiction is a real problem. We have too many roundabouts being put in without proper design with regards to things like visibility and heavy truck traffic. All for a realistically marginal increase in traffic flow and increase in accidents.
Here in Phoenix, people have no idea how to use them. Folks will just stop in the middle of the roundabout to try to let someone in not realizing that the traffic that's in the traffic circle has the right of way.
@@photoniccannon2117That means they're treating it like a rotary then.
That peanut shaped roundabout is actually quite genius. It indirectly also acts as a chicane to slow down the traffic.
Your channel is top notch. Thank you for not incorporating ads into your videos! Excellent work.
Yeah i really love how he only incorporates 2 ads max in his videos
It's a privilege made possible by the 600 contributors on Patreon and viewers like you. Thank you, @thatjpwing!
Yes, TH-cam ads still run (they need to be paid for the video hosting they provide). But I try to limit them as much as I can.
Been traveling that section of Keystone for almost 30yrs now. These roundabouts were a huge God send. Complete night and day difference. Every where I have been throughout Indianapolis (Marion County) that has put in roundabouts, the traffic moves much more consistent and fluidly... .. minus the handful of people that just can't wrap their heads around them and use them like stops.
Wonderfully presented, thank you Rob!
You're welcome. Glad you liked it.
10:30 this bit of psychology is pretty interesting because the same thing tricks people into thinking that bike and bus lanes are useless
they dont see anyone queued up in them(because theyre free flowing) so it looks like there isnt anyone using it
It's insane how nobody talks about this mayor guy. Never heard of him before now, but he's a genuine genius.
In the Netherlands there are a lot of intersections with a lot of lanes that only exist around the intersection. The biggest example I know are three light-controlled roundabouts on N220, N223 and N213 which are all less than a mile apart from each other.
In one case there's just one lane that turns into five lanes before the intersection (1 left, 3 straight on, 1 right). Then between two intersections (about 2,000ft apart) the three lanes continue and turn into seven lanes (2 right, 2 straight on, 3 right). And if you continue to go straight on, the two lanes just turn into a single one again.
All that capacity is necessary, because most of this area is covered by greenhouses, which are very important for the Dutch economy, so there's a lot of freight traffic in this area
Thanks Rob for doing a video series in my area. The roundabouts and construction in the Fishers, Noblesville, Carmel area for the past decades are paying off. Thanks again Rob!
I couldn't afford to stay in Carmel. My cheaper hotel was up toward Westfield/Fishers/Noblesville. If I ever moved there, I likewise couldn't afford Carmel, but would look at that area (not planning to move there, but if I did...)
That was a very clever fix. Carmel, IN is doing stuff right. They've got some great engineers and urban planners.
The real solution would be a single commuter lane walled off from the rest of the road that never stops, but local businesses despise them for bypassing their stores and they can be expensive to build (due to the necessary overpasses/underpasses to be built for cross traffic to pass over.
I’ve learned way more about how Roundabouts are better than red lights in these two videos alone than I ever did. Normally the red light intersections i’ve been in are not in congested areas so I’ve not had to think about the logistics too much.
Rob, I've been watching your videos for a while. I used to wonder if you'd come to the Midwest, but now you've made multiple videos right by and about my home town! Nobody else makes great road content the way you do. Keep up the great work!
I truly believe you have the best channel on all of TH-cam. The quality, the concepts, and your personality all make this such an amazing watch each and every time. Great work!
dogbone roundabout! so happy to see this one
Awesome to see a mayor willing to go through a jurisdictional transfer. Its' really frustrating that the city where I work we have great ideas for state routes, but no one seems to want to pull the trigger and have that discussion. So we keep pointing the finger at who's to blame when it comes to fatal crashes and design. Well done Carmel!
“Just one more lane bro”
"Induced Demand" aka economic growth 😅
@@McfunfaceNo.
@@mcrichards694 Great refutation. Really persuasive.
@@Mcfunface Thx I agree.
Finally part two is here🥳🎉
Up next: PART THREE. (It's accidentally turning into the "summer of roundabouts," but I've got so much material to still share!)
@@RoadGuyRobWhatever it takes to give the subject well “rounded” coverage.
We have done this circle up in the air in Auckland New Zealand - seems to work quite well in tight locations!
Drove across the country alone the roundabout highway interchanges were wonderful
A strong part of the solution is the grade separation of the busy highway from the rest of the intersection. As most of the traffic is moving straight, it does indeed make little sense to stop everyone from moving just to open up for a little cross traffic. Instead, with the through traffic eliminated, all the low-speed traffic and pedestrians can coalesce up in the barbell.
roundabouts are basically the simplest intersection type ever, i really dont get why people hate them so much
If poorly designed, they don't work well. A previous video described some important design aspects to make them work well.
for the same reason zipper mergers work best but people hate them; humans don't play by the rules
That's because people there are uncivilised. Come on a trip to Europe and rent a car anywhere and you'll see how much better not having stopsigns is. I come across 4 or 5 in my 30 min commute and it's already almost too annoying.
I used to not be a fan of roundabouts, but I now am.
People still drive through them too fast, and some are a bit tight for my semi truck. Crossing as a pedestrian or cyclist can be sketchy at a time's. Even with the flashing pedestrian lights, drivers don't always stop.
Bad design is usually the culprit, especially if it's in a place that hasn't built many (or any) roundabouts
As a hoosier, I'd like to thank you Rob for coming to our great state and continuing to produce high quality content for us road geeks.
Awesome video as always Rob! When that lady asked if you were with the news, you should have answered "much more useful, educational videos on TH-cam". We appreciate you man.
I feel like I'm a low-wage local TV reporter - except my market is a TOPIC instead of a CITY.
@@RoadGuyRobI dunno if it's intentional or not, but you nail the reporter "accent", if that makes sense. It's actually a huge reason that I love your videos though I have no idea why.
Great video. Roundabouts work so much better than stoplights in so many cases, wish they were more common everywhere in the USA!
Driving up Keystone/37 in Carmel is awesome for everyone. My Doctor is one intersection north of where the roundabouts and 37 going under ends. Traffic is slower there and no sidewalks. It is jarring. Taking a strode under the cross streets seems simple, but is genius. The Carmel/Fishers area is booming because of this and other things. I would surmise that the GDP increase more than covers the costs for an infrastructure project like this.
Never would have thought to see you right next to my home town Rob! Thanks for sharing the stories and history about it that I never knew!
That's one great mayor!
This man is the only one who can make road engineering fun! 🤩
I’ve been watching TH-cam basically nonstop for the past ten years. This is one of the best videos I’ve ever seen.
I recognized this Rob. They did the same thing on Hwy 41 and 141 (Underpass triple roundabout) and Hwy 41 and 32 (triple roundabout overpass) in Green Bay, WI.
I just love the roundabout way Rob makes these videos...
Another Banger, Robert! Thank you for always including a holistic perspective and the pedestrian experience!
I am always trying to educate people in my community how we can avoid building wide roads if we use roundabouts instead of traffic lights. Thank you so much for making this excellent video that explains why!
Rob, I liked how, at the end, you teased what you'd have in your next video. Great work as always.
For an upcoming project one of my city engineers touted the benefits to local traffic, citing platoons. They will have more opportunities to turn out of their neighborhood since the cross traffic will be "better distributed into platoons" and I knew what he meant thanks to this TH-cam channel. Good work, Rob!
Everyone talking about how good of a person the mayor is (he definitely seems it) but DAMN his voice is amazing!
Here before someone comments "90% of all planners quit one lane before fixing traffic forever". But yeah it is a good thing that we recognize that road widening doesn't actually fix traffic, it just accommodates more cars. The way to fix traffic is to find ways to make best use of the road space that is available, instead of just widening.
That or "just one more lane bro"
Yes, but also making it easier for people NOT to drive is an important part of what Carmel did - allowing for more biking and walking. For bigger cities, investing in public transportation would be necessary. Most trips in the US are short and don't require cars, even in the suburbs. If we designed cities for people, not cars, we'd get a lot less traffic.
@@louiszhang3050 Yeah and cars use a huge ton of space. There is a reason in the olden days not everyone in the city owned a horse. Not that we don't want cars at all, we just want fewer of them, and we want there to be options for those in the city. People in the countryside may always have to drive, and that's fine, but for people in a city a car is a hassle. People may commute to work by car still, but for shorter trips, if those options are available, they will probably walk, cycle, or take public transit, and the few times they will need a car, they will face decreased traffic congestion and less aggressive drivers.
And alternatives to driving so not everyone needs a massive rolling living room to do anything. The people who just wanna go to the store close by can just take a bicycle and get some exercise in while they're at it.
Just one more interchange bro
Your voice of typical american accent gave me nostalgia of my youth days watching Discovery Channel.
As an Aussie who grew up just across the tracks from Canberra/ACT - roundabouts made walking my 60kph/37mph residential home streets to/from school (that often had busses going up/down them) safe and comfortable, whilst also allowing the traffic on the main road through town flow smoothly to peal-and-pack at like 80kph/50mph once outside the residential and semi-residential areas.
What Memorial Circle was was a (Controlled) Traffic Circle and not a proper Roundabout due to the stop-start nature of the signaled segments it was built with, whilst proper Roundabouts are at-worst a Give Way intersection (though it seems Americans don't know how to use those from what I've seen and read) in terms of traffic control.
We Australians call Give Way the Americans call Yield.
Roundabouts work better in Australia because of our "give way to the right" rule which maps into roundabouts. Americans also have "give way to the right" at intersections but roundabouts would need "give way to the left" for the same effect.
Oh and I used to live near the worst intersection in Queensland (corner of Albert St and Station Rd, Bethania) according to RACQ. There was a mix of Give Way and Stop signs and no one could read it. I wish they replaced it with a large roundabout but instead they installed a stupid set of traffic lights. It's ridiculous for a relatively quiet intersection to have to wait 5 minutes at an empty red light!
@@lztx Americans have a "first come, first served" rule. "Priority to the right" is a thing only in some states, and it generally only applies when multiple vehicles arrive at the same time.
Come a little south, to Evansville, IN and help out the Lloyd Expressway!
Rob, I have been watching your content for a couple months, and I've thoroughly enjoyed it and learned a lot!
I was blown away when I realized you don't have a million subscribers. I just watched your video from three years ago about highway on ramp traffic lights in California, and it has all the same style, content, and humor that your new stuff does. I think youre going to just explode one of these days. I wish you all the best, and will be sharing your stuff with friends. Keep it up!
I live on the far north side of Indianapolis, just a few blocks south of Carmel.
I love what Jim Brainard did there. It took real vision.
It's such a nice place to be. Now, the downside of Carmel is it's very expensive (for Indiana) and not very diverse. Carmel is kind of a playground for the rich, but there's no reason a real city like Indianapolis couldn't be at least as urban as Carmel.
I can't believe my city sued to prevent roundabouts. There's so much evidence that they're safer and make traffic flow better.
I drive on 96th Street fairly regularly these days, and the roundabouts are great.
Decisions like this that quietly save lives are under appreciated
This is a very well prodiced video! Thanks for making it.
Fun fact Carmel is the first place in the United States to have a traffic light. You can find a little placard on Main Street
Watch Rob's video before this one, Part 1 of this series.
They need to do this in my city im tired of the traffic!
Grade separation is so incredibly powerful its why we still have minimum spec 2 lane freeways in some very busy cities. yeah they back up, but once the bottleneck is cleared the rest of the freeway clears fast. Unfortunately grade separation is deeply unpopular in urbanist circles, most are just hoping that the efficiency of transit and bikes can make up for the inefficiency of traffic lights.
5:54 in Croatia we call it "Green Wave".
0:45 Sorry Rob but that title belongs to my home city Saint-Herblain in the suburb of Nantes, Western France (which is technically in the western hemisphere). We have 180 roundabouts for a population of only 50000. Stop signs and traffic lights are a rarity here.
Fantastic video!
Pacing, cinematography, details - and most importantly content were great!
Didn't know I could be so enraptured it!
Great video, you touched on a lot of different topics in the engineering world that I had not heard of before. Platoons? Such a cute name for something so inefficient!
4:20 : Coors is an interesting place I’ll just put it at that. Coors traffic is mostly from Paseo Del Norte people, and when Paseo is blocked it usually doesn’t take all that long. When I drive down coors to go somewhere it’s usually not too bad. It’s only when people get off work around 7:00 PM when it starts to get bad. Also the fact that it is 45 through that part is let’s just say … Interesting.
This was a really great video dude! Follow a lot of urbanist youtubers and roundabouts aren't a huge topic so these videos have been really great to watch.
I would have loved to see more of the simulation and also would have liked to know what happened to all of the $100 million, if the roundabout bridge was only a fraction of that. Imagine being a mayor that said, "Oh hey btw I just made our city $80+ million."
We had a traffic circles ("roundabouts") in north Phoenix at Happy Valley Rd. on either side of the I-=17 freeway. During rush hours, one direction of traffic dominated control of the circle, blocking all other directions. A few years ago, the roundabouts were replaced with a Divergent Diamond Interchange, and traffic moves much more smoothly now (although there are a couple of intersections to the frontage roads that have long-wait lights.
Lived in Fishers for three years and drove thru Carmel regularly. SR 37 from 116th northward in Fishers looks quite nice now (well, once they finish 37/141st that is...) but US 31 & Keystone in Carmel are wonderful drives.
We live just north of Carmel. Live the roundabouts. Sure it's a learning curve. But once you know where to go it's great.
The dumbbell (I believe that is the 'official' term) roundabout is a brilliant idea (if it is designed like 9:41), not only it is cheaper it is also safer than oval roundabout.
Oval roundabout is quite dangerous because cars could accelerate at the two bridges because they are in straight lines (like in 9:31) so there are two potential high speed collisions at the roundabout.
Yeah, a standard oval is for single-point intersections, not for interchanges like this. I’m sure this costs a bit more, but it’s definitely safer.
i think i just fell in love with a public official! a competent mayor😮😮😍😍
10:19 this is so true. This entire video gives so much great insight and I feel like everyone in civil engineering should watch these (and the politicians that control the decisions made by the DOT). We could make our roads so much more safe, efficient, and pleasant for ALL users, not just cars, if we started doing things like this. And the new highway in Carmel looks so much more aesthetically pleasing.
Just south of Indy on SR 37, it's getting upgraded to I-69, and every single new interchange is a roundabout (including a peanut shaped one right near me). I'd never seen a roundabout interchange before and was wondering how INDOT knew they'd work so well, and this seems to be the answer! Thanks RGR!
I live in greenwood and we love roundabouts! We need more of them
Each and every video you make Road Guy Rob is better than the one before
Keep up the roadwork!
Love this guy
That section of Mission Blvd in Fremont is also a de facto freeway interchange. It is the closest that 880 and 680 get. 6:24
As a resident of Indy, the Indy gov needs to get over themselves and build more roundabouts. I would love to have them. I think the north side anyway would appreciate them.
The only people who don’t like them are ones who encounter them infrequently.
I love the new roundabouts they installed along my commute home. but ask my family, and "?? I don't get them, theys so confusing!!"
Don't get why people get confused by a roundabout. Not sure what's there to be confused by 😂
Once one figures out how they work they arn't confusing at all.
moreso if they are 2 lanes or less.
It is pretty fun to see little bloopers left in. keeps you human instead of just a TH-cam video.
Rob, you made a critical point, and that is that overpasses can actually improve the quality of life. NY Route 347 could have had a plan like this, but NYSDOT caved in to pressure to create an urban boulevard, rather than use a modified freeway. Our group urged NYSDOT to rethink its plan by adopting what we called a greenway approach using overpasses similar to those on NY parkways. NYSDOT did take on the idea of using overpasses and instead widened the road to three lanes, and widened intersections to accommodate two left turning lanes in each direction. An opportunity missed due to anti-highway hysteria.
nice vid, keep up the good work.
Will do, thanks!
I know it’s expensive for them to do these roundabouts, but it’s like the interstates, it’s expensive to do it the first time but then it’s just maintenance from then on.
Rob, this has been a great series so far, I absolutely love this stuff! Next time I'm passing through Indiana I'm going to make my way to Carmel just to see all this great stuff in action.
If you think about it, a traffic light basicly cuts the time at which traffic can pass down to a bit below 50% (if traffic in both directions is similar).
So to keep the same amount of traffic passing the lights as the road can handle, you'ld need more than double the lanes at the intersection.
So a two lane road, would need 5 lanes at the traffic light. After the light it can go back to two lanes.
The 5 lanes is excluding turning lanes.
But on the other side, a 2 lane road is not often used at full capacity.
I love love love your videos, i hope you collaborate with some other road youtubers at some point as well
Valparaiso, Indiana did something very similar with Indiana State Rd 49 at Vale Park Rd on a smaller scale, and it definitely helps with traffic flow and you frequently see people walking or biking over the freeway bridge and across the roundabouts. I hope the city eventually does the same thing at the two busy intersections north of it and the busy intersection at LaPorte Rd/Indiana SR-2 as well.
Your videos are worth the wait!! Do I wish you posted every few days and had this same quality and time on each? YUP! But that would take a big team and you doing nothing but reading scripts while your team does editing, camera, and scripts. lol... Your research for every video is awesome and the way you explain everything is great. I've always been facinated with roads and roadway engineering since I was a kid. I just had no idea how to get into that industry.
You should check out the intersection of California Sate Highway 76 and College Boulevard in Oceanside at rush hour.
I drove Lyft in Indianapolis for 5 years, the biggest issue I ever had with the roundabouts in Hamilton county was almost getting hit by people who had no idea how they worked.
I have had at least 15 separate incidents of grandmas driving the wrong way in the roundabout and almost hitting me head on
1:27 lol, that gave me a good laugh. Well done! :D
As a pedestrian I hate Roundabouts (especially with no proper sidewalk crossings)
As a cyclist I hate roundabouts (people never notice you, or try to overtake you in the circle)
As a motorist I love roundabouts.
As a part time Bus driver I hate roundabouts, especially multiple lane ones when you need to go to the inner lane to make an exit.
That peanut-looking intersection is actually really elegant! I hope they start doing that around here too.
Super cool design and a great video!
I would love to see a video about the Downs-Thomson-Paradox and how it affects the traffic.
Thanks for coming to my hometown and highlighting this incredible suburban experiment :)
we've got a peanut roundabout over an interstate here too! now i know why they chose the peanut shape. thanks! (our new diverging diamond totally sucks tho. just as slow as before. they are planning on making a bunch of other modifications.)
Thanks!
You're welcome, @SubatomicLaundry! Thanks for your support!
This is a great way to take advantage of the time invested into videos. Great work as always Rob!
Thanks for making this video and explaining it so clearly. I mean this just describes city driving to a T. Half of the road is full, half is empty, half of your trip is moving, half is stopped in a parking lot at a red light. Making more lanes when you don't or can't fix the obstructions to the flow is just making bigger parking lots at bigger and more complex traffic lights that they program to stay red longer and longer. The conversations around the width of the roads just pits people against each other when the "solution" doesn't even work (except if you happen to own a road construction company).
An interesting topic I would recommend is what North Texas has been doing to some of the traffic heavy junctions to improve flow. Check out the junction of Texas 635 and 121, how going east bound, 121 splits into two roads, the right road where the ramp from 625 joins, then the right road splits again with the left half going north, and the right half travelling around the second junction to rejoin 121. At first it seemed like it would be a nightmare, but it made merging from 635 to 121 so safe and simple. Before, you'd have to fight people trying to leave 121, to go North, if you were coming from 635 trying to get on 121, to go East.
the title and thumbnail should maybe be more about the new bridge type
like "This bridge changes EVERYTHING you know about intersections"
100%
The same great video, just now with 100% more clickbait!
Something I didn’t understand about Indiana was how every traffic light are up on wires. Here in Kansas they do that only for temporary lights.
Wire span prevails in New York State too. They look janky as hell. Embarrassing.
Yeah. Around here, all of the permanent span wire signals are old, and they don’t do much with long-term temporary signals (they even have a portable signal at an intersection in place of the mast arm that got knocked out by a truck, and have no plans of fixing it). I honestly wish they still installed them. with the kind of wind we get here (can get pretty strong, but not hurricane level), they can actually be better if done right. The lower anchor wire is definitely essential (otherwise, the electrical wires will get bent around and break).
