Evaluating pedestrian considerations for transit advantage at roundabouts Status: ActiveProject Start Date: 09/16/2025Subscribe for Updates Summary: Roundabouts have proven to be an efficient approach to intersection control for medium-volume roads and generally provide greater capacity than an equivalent stop-controlled intersection. They are often selected due to the observed reduction in fatal crash risk and reduced operational costs. However, some evidence suggests that drivers exiting a roundabout are less likely to yield to pedestrians than drivers at other controlled intersections (e.g., stop-controlled). When considering transit operations, transit advantage treatments such as dedicated bus lanes are often implemented to reduce conflicts between transit vehicles and other traffic. These treatments, however, can widen the overall driving surface, making it more difficult for pedestrians to cross the road. Limited data exists to evaluate how such transit-only lanes impact pedestrian behavior and safety. When transit and roundabouts are combined, both of these issues are present, potentially introducing new hazards for pedestrians. This is particularly relevant near bus or other transit stops, where pedestrian volumes are generally higher. Therefore, understanding the interactions among pedestrian–roundabout, pedestrian–transit advantage treatment, and transit–roundabout is essential to designing and implementing safe and efficient transit advantage roundabouts with pedestrian considerations in mind. The key question is: What considerations and best practices should be applied when designing transit advantage roundabouts? Final Deliverables: Related Materials: Related Research:
