Abstract:

The use of roundabouts is gaining popularity in North America for their safety, capacity and environmental benefits. Studies have shown that roundabouts can significantly reduce injury collisions compared to stop controlled and signalized intersections. As more roundabouts are constructed, there will be an increased need for a detailed analysis of their safety performance. Traditional road safety analysis of roundabouts has relied on the use of historical collision records. This approach offers less complete understanding of roundabout safety issues and their effects on the behaviour of drivers, pedestrians and cyclists. This paper presents a case study where automated video-based traffic conflict analysis techniques are used to diagnose safety issues at a roundabout in Vancouver, British Columbia. Traffic conflicts are automatically identified and analyzed to develop an in-depth understanding of the behaviour of road users and the causes of traffic conflicts. Conflicts contributing factors were identified and several safety countermeasures were presented.
