Why Do We Have Roundabouts?

Why do we have roundabouts? According to the Federal Highway Administration, roundabouts can increase traffic capacity by 30 to 50 percent, compared to traditional intersections. According to a study by the Insurance Institute for Highway Safety, roundabouts also reduced injury crashes by 75 percent at intersections, where stop signs or traffic signals were previously used.
