This project examines the safety aspects of modern roundabouts with respect to pedestrians. Since the emergence of modern roundabouts in the US, safety has been recognized as a major concern for the effectiveness of roundabout performance. Pedestrians may be more prone to unsafe crossings at roundabouts due to new geometries, signalization (or lack of it), right of way assignments for pedestrians and vehicles, and visual and auditory cues. This project documents case study, statistical, and simulation analyses regarding pedestrian safety at roundabouts. The results suggest that roundabouts are safe with respect to pedestrians. This report includes the following topics: Literature review summarizing international and US experience with roundabouts and pedestrians, alternative research approaches, case study analysis of a candidate roundabout intersection in Raleigh, NC, statistical analysis for pedestrian crashes at the case study intersection, and simulation of the case study intersection vehicle and pedestrian movements with the original intersection and with the candidate.
