Proactive Assessment of Pedestrian and Bicycle Safety at Intersections Through Video Analysis of Right Turn on Red Maneuvers

Intersections are critical points in urban traffic systems where different modes of transportation converge, including vehicles, pedestrians, and cyclists. However, despite efforts to improve safety measures, intersections remain sites of significant risk, particularly for vulnerable road users such as pedestrians and cyclists. One significant contributing factor to this risk is the practice of right turn on red (RTOR) maneuvers, which can introduce conflicts between turning vehicles and pedestrians or cyclists crossing the intersection. RTOR maneuvers at intersections represent a convenience for motorists but often pose significant safety risks for pedestrians and cyclists. Therefore, there is a pressing need to develop innovative strategies that leverage advanced technology, particularly video data analysis, to better understand and mitigate the risks associated with RTOR maneuvers at intersections. Utilizing safety surrogate measures, such as post-encroachment time (PET), offers distinct advantages over relying solely on crash history data. These measures provide real-time insights into potential safety risks, offering a more comprehensive understanding of near-misses and risky behaviors, and enabling a proactive approach to intersection safety management that can effectively mitigate hazards and improve overall safety outcomes. By utilizing PET, extracted from continually collected video data available to the research team, this research also seeks to capture the severity of RTOR-related near misses, providing valuable insights for targeted safety interventions.
