This professional paper reviews current research on the safety of modern roundabouts and studies the recent, widespread use of them in the Las Vegas valley of Southern Nevada. A roundabout is a form of intersection control (as opposed to a traffic signal or stop sign) that is common in Europe and Australia. Only recently have they been used significantly in the United States. A safety analysis of roundabouts in the Las Vegas Valley was conducted. The study reviewed accident data and hard copy accident reports, obtained average daily traffic counts, and compared these operational aspects of the roundabouts with intersections serving similar traffic volumes controlled by the more traditional traffic signal or stop sign. It is the goal of this paper to fill a void that exists within the available research that has been done on roundabouts throughout the world. Specifically, the roundabouts studied in this paper are all roundabouts that were built during initial construction of new roadways whereas prior research has focused on roundabouts that have replaced other forms of intersection control at existing intersections. In addition, this paper adds to the limited research that has been done on roundabouts operating in the United States.
