Gawd this would be nice.

This needs to become the standard. Protected bike lanes are a solved problem, we just need to install them already
Posted 11 years ago and we have exactly zero of these in my city still.
Cars would be hitting and driving over those 4 lens shaped bits of curb all day.
Are you talking about the bit past the parking lane?
No, thw rounded corners of the intersection
I mean if they are like the triangle islands they sometimes use for pedestrians and dedicated right turns it might. Just have to make it to thin for a car. They are way to far out in his picture and for some reason even the bike lanes come away from the curb at the corners. I think it might just be bad drawing.
Would be pointless in a place like Alberta that’s for sure. Unless you add a lot of deep sunken bollards. Pickup trucks will just ride right over those curbs and plow into anything as they currently do.
Jersey barriers work in these cases.
We have one of these in Seattle! We could use a lot more.
Please don’t reinvent the weel and just install a Turbo Roundabout. It’s much safer for everyone, incuding cars.
They just put in like six of these on the main street of my parent’s town in Washington. For a route that would otherwise be a stroad they beat the heck out of a traditional signaled intersection, but do little to make the area any more hospitable for biking and walking as they still take up so much space and feature continuous traffic. So, quite good for through routes but not great for density or street “completeness”.
Turbo-roundabouts aren’t really urban infrastructure though, nor are they are one size fits all solution to traffic.
They take significantly more space than an intersection would, and are generally used to improve traffic flow for cars, not bikes. Even in the Netherlands they are generally only used outside of cities on main routes for cars, with segregated bike infrastructure to keep cyclists out of the roundabout.
It’s car infrastructure, not bike infrastructure.
Edit: I also feel the need to point out that this intersection is not reinventing any wheels.
Protected intersections for cyclists like this are common all over the Netherlands, and are a proven piece of infrastructure when used in the appropriate way.All bike infrastructure is car infrastructure.
We wouldn’t need any bike infrastructure if we just limited all roads to 30kph.
That looks more complicated then the average U.S.A. driver can navigate. Hell they struggle with bike lanes and stop signs. We need more stringent driving tests
The average US driver can’t navigate anything and is crashing at signaled intersections all the time already. This at least gives them more guardrails and contains the carnage better.
They are easier to navigate than a regular multi-lane roundabout. The only thing you need to take into account is to sort into the right lane before the roundabout (which requires proper signage) and then it reduces risk on the roundabout itself by eliminating the possibility for lane changes.
It helps keep the flow of cars going smoothly, which is their main benefit.
Source: I live in the Netherlands and turbo-roundabouts are all over the place here.
Easier than a regular roundabout and they looks wonderful. The problems are not its design. The average intelligence of people in the U.S.A. is a bewildering thing. So many people truly and well do not understand traffic rules. They do not understand whay should be basic understanding. I have had people argue with me how stop signs work, how lane end merges work, Ive had people argue to me that it is mean to teach children not to randomly touch people.
The turbo roundabout looks amazing and I would love the opertunity to experience it, many Americans ar incapable of using it. They will blame thier ineptitude on it. We are still fighting for pedestrian walkways, maybe bike accessible infrastructure in more liberal left cities. The people allowed in cars right now are not all ready for a roundabout, no matter how good it is. It is so sad I know they cannot drive in a circle that is too advanced…
People ignore stop signs and bike lanes not because they don’t understand them, but because they willfully ignore them (and the bike lanes are not physically separated). There would be a learning period, but if they were common enough, Americans would learn to use a turbo roundabout, though the same conditions that make them blow through stop signs (or red lights!) would also affect turbo roundabouts some way. I have been in regular roundabouts in the US that people seemed to understand just fine.
Certainly there are people that willfully ignore them which is a big problem. There also alot who actually do not understand stop signs. 10% of the time there is at least one person seemingly mystified on how to proceed through a stop sign. And 50% of the time a lane beside me ends I have to be careful not to get sideswiped.
These two groups of idots are why protected bike and pedestrian lanes are essential and why roundabouts will be difficult.
Those people that blow through stop signs and lights will do so in roundabouts and then blame the roundabouts for thier idiocy. Then other idots will nod along saying its the roundabouts fault.
Perhaps with an adjustment period it can work but any politician greenlighting one will get attacked and once there are accidents any politician still supporting them will be attacked.
The idiots are loud and sway way too much politicians, like gestures vaguely at current USA federal administration
