Nearly all transportation agencies will tell you that safety is their absolute top priority, but if you look more closely, you’ll discover that—in practice—i...
It does lower speeds, you can’t just fly through a roundabout even if you’re going straight through. You can easily blast through a regular intersection at 100mph if you want.
They have higher throughput though, so it’s “faster” in that sense. Lower peak speeds, higher average speeds (as you’re not stopped for a long time).
But to be fair… putting down a single sign at the start of every red divider even if it’s still under construction would have prevented most of that insanity.
That’s only if you are crossing through a roundabout, which I’ve never seen for pedestrians. Pedestrians have to walk around the roundabout as well, crossing the two way streets that leads up to it and still having to look both ways for cars leaving and entering the roundabout. This is usually helped by a median but a regular intersection can have a median as well to accomplish the same thing. These medians will also usually create a slip though like the author says in the video, which allows cars to take right turns at speed, if the roundabout is empty, without checking for the crosswalk they’re turning into.

Disagree
That’s the point of a roundabout. It lowers speed at the crossing while also increasing throughput compared to a regular crossing.
So you can indeed lower speed at a crossing area while not lowering the speed of traffic overall, just by eliminating the waiting times.
Yeah, but then us Americans have to learn how to drive in circles and that’s really hard apparently.
Where do you live? Roundabouts are pretty common in much of the US anymore.

Roundabouts exist in the oldest parts of the US. Go east and you’ll find them everywhere.
They lower speeds, just not to a stop which is good for traffic throughput and emissions.
Plus pedestrians don’t have to look both ways to cross, since traffic is only coming from one direction

Alex, what is a “pedestrian bridge” for $500?
