      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).

      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.

          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.
