(The case for more traffic roundabouts)
From Priceonomics: “The roughly 3,700 circular traffic intersections in the U.S. are feared, avoided, and even loathed…Australia has more than 10,000. France features 32,000. The U.K. boasts 25,000, the most in the world as a proportion of total road space.
In every single metric, roundabouts outperformed intersections in terms of efficiency. Average delays were cut by 65%; no more than one-third of vehicles were not in motion at any given time, and the circle never went over 22% of its full capacity.”
From Discover: “The roundabout is the single most important device ever created to help control traffic safely and smoothly.”
