Abstract:

A roundabout was defined by the Florida Department of Transportation as "any intersection of two or more streets that is designed around a central island." Roundabouts are designed as an effective traffic control measure to resolve conflicts between two competing traffic movements. The basic principle is to channelize the vehicle paths in order to disperse the conflicts that are concentrated at a conventional intersection and resolve each one in an appropriate manner. Roundabouts allow continuous flow of traffic while slowing down vehicular speed. There are three main differences that distinguish roundabouts from traffic circles: yield-at-entry, deflection, and flare. Traffic circles are ideally designed to operate within the geometric constraints of the intersection and are also designed to cause vehicles to come to a complete stop before entering the circle.
