Developing Guidance on Leading Pedestrian Intervals and Curb Extensions to Improve Pedestrian Safety at Signalized Intersections

Improving pedestrian safety continues to be critically important to Oregon Department of Transportation's (ODOT's) mission to provide a safe and reliable multimodal transportation system. Approximately 920 pedestrians were injured, and 78 pedestrians were killed in Oregon each year between 2016 and 2020. Some of these pedestrian-vehicle crashes occur at intersections, where agencies have installed either geometric or operational countermeasures to improve pedestrian safety. Leading Pedestrian Intervals (LPI) allow pedestrians to start their crossing prior to conflicting vehicles. Curb extensions improve the visibility of pedestrians to drivers, shorten the crossing distance, and slow turning vehicles. ODOT uses both options to improve pedestrian safety but guidance is lacking to optimally evaluate and select these options (separately or in combination).
