Differences between Traffic Circles and Roundabouts

A Traffic Circle is a circular intersection usually found in residential areas. It is designed to slow traffic and help reduce crashes  Traffic Circles are often used for traffic calming and are usually smaller than roundabouts. Traffic Circles have a center island, but they typically do not have splitter islands or other design features found in  roundabouts.
