From Wikipedia, the free encyclopedia
A roundabout or rotary is a type of road junction (or traffic calming device) at which traffic streams circularly around a central island after first yielding to the circulating traffic. The first actual modern roundabout was constructed in New York City in 1904, but the widespread use of roundabouts began when British engineers re-engineered the traffic circle in the mid-1960s to overcome its limitations of capacity and for safety issues. Roundabouts are statistically safer than both traffic circles and traditional intersections, though they do not cope as well with the traffic on motorways or similar fast roads.
