Carmel is internationally known for its roundabout network. Since the late 1990’s Carmel has been building and replacing signalized intersections with roundabouts. Carmel now has more than 125 roundabouts, more than any other city in the United States.

Roundabouts move traffic more efficiently and reduce the number of fatalities and serious-injury accidents. They work because of their safety record, their compatibility with the environment, their aesthetics and their ability to make it easier for pedestrians and bicyclists to navigate.

The number of injury accidents in Carmel have 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.
