ROUNDABOUTS
This set of roundabout (traffic circle) visualisations show a deficit of domestic roundabouts in the U.S. compared with countries like France, where motorists are 25 times more likely to curve through one than in America. U.S. roundabouts are not spread evenly throughout the land, but amass in certain places like Florida (1,283 roundabouts) and virtually disappear in others like the Roundabout Bermuda Triangle of Wyoming/South Dakota/North Dakota (not even 50 among the three).
This project was prepared for City Lab in 2016.
