Carmel has become internationally known for its roundabout network. Since the late 1990’s Carmel has been building and replacing signalized intersections with roundabouts. Carmel now has 100 roundabouts, more than any other city in the United States.
Carmel builds roundabouts because of their safety record, their compatibility with the environments, their aesthetics and their ability to make it easier for pedestrians and bicyclists to navigate. In Carmel, where roundabouts have replaced signals or stop signs at intersections, the number of injury accidents has been reduced by about 80 percent and the number of accidents overall by about 40 percent. Our numbers are similar to those reported by the Insurance Institute for Highway Safety.
