Road design, safety and Vision Zero

[tomh009]

I do also wonder if some of these problems are just inherent to the large 2 lane roundabouts we almost exclusively build. My impression of the Netherlands is that at-grade roundabouts are almost all a single lane, and multi-lane roundabouts are usually grade separated. This would suggest that cheaper engineering solutions being suggested here aren't adequate for multi-lane roundabouts.

UK is full of roundabouts, and many of them with two (or more) lanes. But grade separation is exceedingly rare, at least where I have driven or walked there.
