This research compared the performance and safety characteristics of roundabouts to signalized intersections. Accident records by type and severity, traffic delays and traffic volumes for conditions before and after were obtained from the Department of Transportation in Keene, New Hampshire in order to analyze data for the comparison of the two traffic control systems. Following this research, further analysis should be carried out to ascertain the real benefits of roundabouts over traffic signals.
