As noted in the US Department of Transportation Federal Highway Administration's publication Roundabouts: an Informational Guide, modern roundabouts were developed in the 1960s to address problems associated with traffic circles. However, there still may exist some confusion between the roundabout and similar circular intersections. This confusion may lead to opposition in considering a roundabout as a viable alternative for intersection-related projects. There are safety, operational, environmental, and economic benefits associated with roundabouts. Hence, it is important that the differences between roundabouts and other circular intersection forms be communicated accurately. To illustrate the differences between roundabouts and other circular intersections, this case study was performed using data from the state of New Jersey. The aim of the study was to show the differences between roundabouts and traffic circles as they relate to safety and operational performance metrics and geometric features. Defining safety, operational, and geometric characteristics may help promote the implementation of roundabouts by eliminating the confusion that exists between roundabouts and traffic circles.
