Wow. I am aware we have excellent roads and city planning here, but i never thought of our signals to be particularly smart. We have so called "green waves" where the traffic lights on a road are all connected so they turn green at an interval corresponding to their distance, so that when you drive at about the speed limit, you will have all green lights. Those are only in a few places though. I am still hoping someday (soon preferably) someone starts developing actual smart systems where signals in an entire city are connected so that basically every street has a green wave and crossing streets with green waves can be in sync. I would imagine this should be especially feasible for US cities with the squared design. Just imagine all lights to be in sync, with waves of cars moving on the intersecting streets in a way everyone can almost always have green lights.... (id make every read 1-way in such a grid as well, but i imagine that is already being done a lot. I saw it a lot in central american grid design cities)

Traffic signals are a science. Not just the road design, but the timing, prioritization of traffic directions according to time of day, having slower cycles when traffic is heavier, having more short cycles for pedestrians and cyclist and fewer and longer cycles for cars in the same intersection. And more.

It was such a weird feeling to be the only non-homeless person walking through a city center, having to constantly check over my shoulder to make sure no one was about to run a red light and hit me, and even then I actually had to stare down an SUV because its driver apparently couldn't see my 6' tall runners frame crossing the street when I was given the crossing light. It all felt especially odd coming off of an internship in Washington, DC, where pedestrian traffic is much more normal and while the infrastructure still clearly favors cars, the laws and policies are at least catching up with where they should be. There, I could at least pretty comfortably walk across a street without fear that some distracted driver wouldn't notice me doing arguably the most human activity ever.

Roundabouts or traffic circles definitely don't scale to large sizes and fast speeds. There is a gnarly one in Chicago that has claimed many casualties.

Amazing video! The issue in America of roundabouts being added as a response rather than a precaution is very much true. Near me there was an intersection exiting a school that saw a very high number of collisions constantly. It was redesigned as a 2 lane roundabout. While the number of collisions has decreased, the risk for pedestrians stays nearly the same. People drive straight through it without slowing down, ignoring the painted lanes. It's as if the roundabout isn't even there!

US traffic engineers mistake multi-lane traffic circles for true roundabouts. They like them for supposedly being able to allow more traffic to pass through, until someone causes a collision in a traffic circle. Another mistake with implementation of roundabouts in the US is lack of accommodation for pedestrians, people on bikes, wheelchairs, etc. There are so many examples of safe and well-functioning roundabouts but we fail to simply re-apply what has been proven to work.

Multilane roundabouts (called turbo roundabout in The Netherlands) in America should get raised medians instead of painted lines, that would prevent speeding on roundabouts. If drivers aren’t behaving, they should be guided instead, between raised medians you can’t switch lanes like with painted separations. And why on earth doesn’t America use smart traffic lights? Waiting times for traffic lights will decrease massively. It seems that America is so backwards with road infrastructure, they can only think in more car lanes, dumb traffic lights and stop signs. Our roads of 2 lanes (one in both directions) with lower speed limits flow much better and with higher average speeds than 10 lane stroads in America. Don’t muddle through or invent something new, just copy and adjust the scientific CROW guidelines of The Netherlands. It is that easy, to get higher average speeds and less traffic casualties.

Add the time it takes to get to and from the trainstations as well as the money needed for those busses and i need about an hour less time and 10 less euros to use the car instead of the train. And that includes maintenance and value loss on the car. And then you need to realize that the car is heavily taxed in every way imaginable and the train is subsidized.

I think flow types will only be able to be separated once land-use types (I don't mean separation of uses, I mean suburban style development vs traditional development) are separated. A grid system like those in the Midwest and the southwest would be fine as long as it looked more like the traditional core of a city. You can have your long roads in rural areas but once you reach a town or city that is where you have something like a roundabout, and then from there you could still have a grid but the city blocks must become smaller. Driving lanes are narrowed and separated from sidewalks and bike paths, and transit exists. The key is to build a place where driving doesn't have to be your main option for moving around. The future of stroads lies in whether they should be turned into a road or a street. Remove signalized intersections and limit access? Or remove/narrow lanes and intensify surrounding land-use? I feel like it depends on the particular development.

In the Netherlands towns and villages usually developed along a road, waterway or at a place for crossing waterways. The fisrt two are stretch out through the middle and when road traffic became too busy, a road was constructed around the community. So this system developed over time until it got official policy in 1995. If you have to change a large grid system around, that is going to cost a tremendous amount of disruption and capital. In short : COUNTRIES WITH A PREVAILING GRID SYSTEM ARE TOO LATE!

There are more categories than that. Roads are divided into highways (marked with a letter A), with speeds between 100 and 130km/h, then there are the long roads (marked with a letter N) that are between 60 and 100 km/h, then there are the short roads that are 50-80, then we have streets, that are 30-50. And we have bike streets where bikes have priority and cars are only allowed for people living in that street who are commuting home, other cars have to make a detour, and then there are pedestrian/bike only streets. These last two categories are one of the main ways cycling is promoted in the Netherlands by having the most direct ways in and out of city centers be bike only and making cars take detours to get there. As well as extremely limited and very expensive parking in the city centers. A few hours in Amsterdam could easily cost you 30 euro for parking alone, so its cheaper and faster to take the train and rent a bike. In most towns you can commute from your home to the town center, or the train station in the town center, faster on a bike than in a car, and due to traffic its usally faster to take the train as well unless you need to go to a very remote area. This all helps to drive down car use, sadly our public transport is underfunded, understaffed and overcrowded since covid, so people are driving more now than they did a few years ago.

This was quite informative, as an American who doesn’t really understand why traffic is so bad here. Thank you for the lesson!

One of the (many) issues with roundabouts in Canada is drivers do not know how to drive through them. There were zero roundabouts in Nova Scotia when I got my license.

And people complain, because of course, that's insane. No effort was made to rethink how to cut down the number of intersections for this high-volume arterial.

With this solution, speed is reduced, transition to the side and service streets made easier and it looks nice... Not a traffic necessity, but serves its purpose.

One Easter, we rode our tandem with a camping trailer across Flanders and the Netherlands to visit my brother, who was stationed at RAF Laarbruch on the Dutch/German border. Our most recent trip involved a tour by converted barge from Amsterdam, cycling between each night stop. I can confirm that, though the scenery is less than stellar, the cycling facilities and the people more than make up for it. On one longish trip from Rotterdam east almost to the German border we were glad to be able to use a cycle track alongside a motorway to cross the many waterways near the coast. That's very rare in the UK. I just wish the UK would adopt this method and take non-motorised travellers into account when building roads.

It seems the crux of the problem is scope; projects are often limited in scope to a single intersection or perhaps a handful.

Still, my city is currently trying to figure out where to install 25 miles of protected bike lane because of their vision zero plan, and my main road is definitely one of the contenders!

I learned while living in Nairobi that just as there may be a minimum traffic density under which roundabouts are unnecessary, there is a maximum traffic density above which roundabouts just cause traffic snarls. Many times, I have seen a small roundabout brought to a standstill by gridlock, compounded by failure to yield right of way by any of the drivers in the roundabout.

I've found from my interactions with north american engineers that they don't have a scientific bone in their bodies. They are more like monks who can only memorize and recite their holy scripture. They never question scripture, if it's in the manual, it's truth. They don't even care about the results. You can show how deaths at a poorly designed intersection have gone up, how congestion is worse, but they don't care. "The design followed the standards to the letter" thus it is perfect. If people are being killed and injured, its their own fault because the standards are perfect so the users must be the problem.

This was great. I would have liked to have seen more mention of UK style mini roundabouts, which solve a problem common there - the meeting of streets with equal precedence. With unequal precedence you would have a give way, but the UK does *not* have priority to a direction by default! Most of Europe does, the USA does, but the UK doesn’t, so meetings of equal roads cannot be uncontrolled.

I have yet to find a single hobby that isn’t niche The only one that’s kind of pushing that definition for me is music Also, great video

One US state, Michigan, seems to love to rebuild intersections as roundabouts. Because Michigan is not a through state it can get away with it, I have seen this even in rural areas. They greatly slow speeds and reduce accidents at the expense of speed.

Hey, I just saw your podcast episode with NotJustBikes and was curious if you know anything about the 'latest and greatest' diamond intersection. They just opened one up last year in Niagara, Ontario, and apparently the first one was in Calgary, Alberta 6 years ago. It would be cool to see whether this type of intersection exists elsewhere in the world, what its purpose is by definition vs. how people actual behave around it, and whether it actually improves anything or if it's just another stroad accessory. I am also a civil engineer that was pretty disappointed in the transportation engineering courses and industry here in Ontario, but my line of work is outside the transportation industry. I am continuously disappointed with how Canadians approach transportation engineering lol.

What you state in the video is correct, I think. But don't forget that the move in the Netherlands to a more science and safety based road design started in the '70ies .. Still it is not ideal. I mention that fact to indicate that it will take a very long time so see real improvement in road safety, not to complain. The achievments are clear and it's an ongoing process. Don't forget that every long journey starts with the first step.

well thanks for showing my birthplace in the first few seconds , 2nd is den bosch 0:13 ! 🙂 ......... btw roundabouts are usefull , howmany times in the past i almost got runover by crossing a street ........ where it fails is when drivers lack the money for "blinker"fluid !

Spain loves roundabouts to the point where they've replaced nearly all intersections. And they just haphazardly install the dual lane version basically everywhere. Add to that the widespread bad habit of not using indicators and you can imagine what happens in many Spanish towns and villages. As a Dutchman I still don't know how to use these roundabouts properly and I've already had several months of practice.

Keep seeing London Ontario in these videos makes me laugh 😂

Yes, there is so much to the humble roundabout! Here in the UK there are still all sorts of design 'issues' such as direct (not tangential) entry lanes that have little central roundabout area so drivers often look ahead and just rush across as there is little to 'physically' slow them down. Another issue is with pedestrian crossings just on the outgoing lane of a roundabout where the driver is looking far ahead and accelerating! Or those that feed specifically busy roads so become clogged (against the Highway Code I believe) impeding all through flow. And of course the wonderful Traffic Circle where a roundabout has traffic lights added to it, and not always on all lanes! Yes design and some kind of future proofing needs careful thought!

I really find it funny how American City planers are seem less expirienced in building roads than me in Citites Skylines.

As a Dutch guy here's my two cents: Trying to implement this in (for instance) the US would go way deeper than only changing traffic-, housing-, and commercial infrastructure, effectively splitting current large city centers up into a lot of small ones. You'd need to change people's mindsets, and there's a big chunk of the challenge. Also the "15 minute city" concept might be interesting for you to check out, but you probably already did! 🙂

A good and interesting video! It was interesting all the things one need to take into consideration for the roundabout. One thing that could be improved, both for this video and in general, is sources. There must be some source for all this interesting information!

Much of America was rather undeveloped at times when European cities were already built and ready for planning. During that time, the focus in America was on creating arterials to connect over vast distances. The problem started when development occurred along the arterials rather, due to a need of "quick access" by business owners (like Breezewood, PA). There was no impetus at the time for separate collectors. This occured in unincorporated areas before any municipal planning could take place. So we were stuck with arterials trying to do the job as a collector as well, creating a grid of stroads, and failing at both.

"... at times when European cities were already built and ready for planning" 3 mistakes in this sentence. Firstly, most American cities existed before the car, used to be walkable and to have transit. Secondly, a city don't need to be big in order to be planned. On the contrary, the earlier a city start, the better it is. Thirdly, American cities started to be planned at the same time than European ones. Actually, modern urban planning started in the 19th century in Europe, with Barcelona and Paris being great inspirations for some US city late 19th century. In 1900, the share of people living in urban area was nearly the same between North America and Western Europe (arond 40%), with some American cities, such as New York, being bigger than European ones. Yet older, European cities were not bigger. So, litteraly, US cities were in same position than European ones when car became more accessible. For that reason, the US have no excuses for having bad city planning. They choose it. Actually, it's well documented that the petrol industry influence a lot American governments in favor of pro-car regulations: interstates, parking minimums, to dismantle streetcars, etc. You should check Not Just Bikes videos on KZread (if you are interested in the subject).

@@rouphile That is not what I was talking about. This is beyond modern urban planning and not just cars. The major European cities were largely established in 10th-13th centuries. While there were urban areas in the 17th-18th century, many US had many cities in mid-America developed in 19th and 20th century, as the US was still expanding. While European cities already had forms of transport between cities for centuries and established country borders, America was developing and expanding within the past two. With the advent of rail, many US cities were developed as a result of them and not prior. Much of the 20th was focused on connecting these US cities with the new highway systems. This also resulted in newer cities being established along the transcontinental system. Because of the hundreds of miles between these communities, car access was deemed essential. Hence why vehicular access was a staple in urban design. The mistake was all roads would be designed similar to transcontinental highways and not as separate local roads. One reason I do not fully promote "Not Just Bikes" is that it would not fully apply to the America landscape due to different histories of development. That is not to say the Dutch cities has a great form of urban planning/design, nor is that to say car culture had no impact on American urban design standards. There is improvement necessary without a doubt. Due to America's very large and diverse terrain, and connection to the vast rural communities, such a band-aid would not fix the issues. But this diversity has also shown areas where urban planning and design has greatly transformed places to walkable communities, as America is anything but a monolith. Many US cities do show the mistakes of bad urban design standards.

​@@rouphile thank you, that is a very clear explanation. US cities just bulldozer led their old towns to make room for multi lane roads. Its a choice. One that we in the Netherlands also started to make somewhere in the 1960's, but fortunately, there was a lot of protest against these plans, so not too many where actually executed.

Thanks for this video. I personally think for my city of Kitchener-Waterloo does a better job in newer developments to distinguish roads vs streets. However, those rules are thrown out near shopping centres. I honestly think many of the region roads going through the city need to be 2 lanes instead of 4 lanes. And add turn lanes when needed. In tighter an older sections this will free space up for trees and bicycle infrastructure. In newer areas this can lead to more space for trees. Most newer regional roads have a right of way of 40 metres. In that right away there are 4 lanes, a median or grass boulevard, plus 3 metre multi-use paths on either side. When bicycle traffic increases there is more than enough space for 1.8m sidewalks. My city claims to be innovating the roundabout but they need to stop their attempts of innovation like their attempt of a Dutch roundabout. They have signs telling cyclists to yield to cars but cars need to yield to pedestrians. They even use shark teeth before the pedestrian and cyclist crossings. This should cleary saw who needs to yield to who but they complicate that with signs. I am hopeful for where I live but these few things annoy me. 😜

I am glad roundabouts exists in the Netherlands. I literally lived near places that prior to roundabouts dozens of people died on and hundreds of car collisions happened. Like as a Dutch I am glad we care and invest so much in roundabouts it saves lives and traffic time.

I have trouble with two-lane roundabouts. Getting into and out of the correct lane gives me too many cars to yield to. I've never driven in the UK, but they rely a lot on painted lane info rather than overhead signs. The lane info gets worn, and it's hidden by the car ahead until it might be almost too late to get in the proper lane. I know overhead signs are ugly, intrusive and expensive, but stupid drivers like me need them.

As a general rule, signal right a few moments before the preceding turn so you have some time to merge. Every single instructional video I've seen from North America gets this wrong.

I like our smart intersections. Even if the light for my direction is red by default, when there's no intersecting traffic, I can just calmly roll up towards the red light, and it'll jump to green. It'll go orange as soon as I pass, so that the lights for the bigger throughfare can default back to green. How is this not used everywhere? I mean if you can make traffic lights on a timer, how much more work is it to install some sensors?

@NewBuildmini

8 ай бұрын

America already has them, and had them for a very long time. But unlike the Netherlands, they are less efficient in the US due to them attempting to minimise costs wherever possible. "Semi-actuated" signals with detection only on the side roads and in left-turn lanes, resting in green on the main road, are a common example. If there is barely any traffic on the main road, side road traffic will still have to wait for the light to change. In the Netherlands on the other hand, all movements have detectors, allowing each movement to be given an appropriate amount of green. This also allows the traffic light to rest in all-red when there is nobody around, allowing the traffic light to immediately change as soon as a user is detected. Also, the US tends to have 1 detector per lane, mostly at the stop line, both for requesting a green light and for extending a green light. When the light is green, this means that when the last car passes the detector, the light will change a few seconds after that car has already left the intersection. In the Netherlands, a movement usually has multiple detectors for different tasks, allowing each of them to be positioned at an optimal distance. There is always a "calling" detector, and an "extending" detector". There are often 2 calling detectors, the first being positioned before the extending sensor, and the second being positioned at the stop line like in the US. The extending detector is positioned a few meters before the stop line, allowing the green light to change just a second before the last car crosses the stop line. And the most important part, is that American signal controllers operate on an outdated "phase-based" structure. While a "phase-based" structure is more flexible than a "stage-based" structure (in which signals may only be green in designated parts of the cycle called "stages"), it's still less flexible. The "flexibility" generally only applies to left-turn phases, both of which can start and end at different times. The through phases generally must end at the same time, even if one of the through phases has no traffic. Also the all-red clearance period is fixed for every phase, often causing unnecessary delays. Dutch signal controllers operate on a "group-based" structure, where each movement operates independently from other movements. A request for a green light can be serviced immediately as long as this group would not conflict with other groups currently green. The all-red clearance period can differ depending on the group starting and the group ending. This allows different groups to be combined based on the users present, which is significantly more efficient than a phase-based structure.

I think it’s also important to consider social context as well. There’s a reason why France has so MANY roundabouts and mostly gigantic (50m - 100m diameter in builtup areas and 150m - 250m in rural areas is standard) multilanes ones. In France running red lights is almost like a national sport and therefore, even multilanes fast moving roundabouts r still safer than a traffic light intersection. It’s to the point where I feel safer on rural roundabouts with country roads intersecting with traffic moving at an avg of 85-100 km/h than a traffic light intersection! So they build them absolutely everywhere.

To be fair, I feel like French drivers have bettered themselves a lot in the last two decades. I'm from Germany and French drivers had always have the stereotype of being bad and dangerous drivers (just like Italian, Belgian, Eastern European,... the Germans definitely have a superiority complex when it comes to driving skill). It is still a notable difference when you drive in France versus in Germany (passing on the right, cutting people of, not yielding) but it is a lot less than back in the day, where it seemed that things like speed limits, stop signs, red lights and line markings were all just rules that were meant to be broken in France. But something changed, probably connected to the quite high fines for traffic violations.

It is also important for the placement of a roundabout to know about traffic patterns. If there is high traffic frequency taking the last exits it will cause the entire roundabout to be jammed. Also roundabouts remove almost all of your speed so some roads are better left with a 'green wave' of smart lights than with a roundabout. Traffic jams on a roundabout can get far worse than a traffic light. Some road users cause it to jam up too much, in the Netherlands we also have roundabouts with traffic lights, allowing for massive throughput and controllability of the main arteries.

I prefer roundabouts almost every time. It makes traffic much calmer. Simpy coast towards it, merge into traffic and gently start to accelerate on the outward turn. No Formula 1 start when the light get's green so you can reach the speed limit quickly and get the next light on yellow. No slamming the brakes after entering the intersection at yellow just to make the 90 degree turn afterwards. And if you have to give right of way, you just loose a few seconds, not minutes. Saves so much time, energy and reduces noise emissions.

Nice video :)

I live in an area (outside the USA) where there are a lot of new roundabouts. The best use of these are the small size circles in residential areas where intersections between 2 low-traffic streets have become a lot safer and easier to move through, since the roundabouts replace stop signs. Stop signs should be outlawed since there is no reason to stop if there is no cross traffic, and really bad accidents occur when you legally cross an intersection hoping/praying the distracted (or dui) driver coming at you broadside will actually stop. Some roundabouts have replaced traffic lights, significantly improving throughput for higher-traffic streets, allowing smaller cross streets to enter and cross or turn left without issue. I would say that roundabouts (even as retrofits) should be the primary tool in the road designer toolbox, resorting to lights and overpasses only when really no other option works.

@Landrassa1

There are situations where stop signs are useful. In the Netherlands they are typically used when visibility at an intersection is so limited (in some cases intentionally so) that coming to a full stop is necessary. However, this only works because they are used so sparsely that when you do see one, you know it is there for a damn good reason.

There are a lot of small roundabouts in France, notably, where vehicles can go up the center of the roundabout slightly higher. These are good solutions for streets intersection. Moreover, for Public Transportation, roundabouts allow buses to turn around at the end of a line instead of passing through small streets do to so, or worse to make inefficient and confusing for customers, big one way loops !

I appreciate the Haarlem content
