” When America began to aggressively expand its highway network after World War II, engineers dropped the rotary in favor of signalized intersections. But other countries stuck with the roundabout concept. Over the years, they developed improvements that led to today’s smaller, slower and safer roundabouts.
Roundabouts “are not just some Scandinavian social-science program,” .. “They’re based on a lot of traffic engineering science, developed primarily out of the U.K. and Australia.”
So highways engineers in Minnesota are trying to reassure drivers about them with the video below. It’s slightly weird to see a familiar concept here treated as something odd on the other side of the Atlantic…
