(September 18) Effective Countermeasures to Reduce Pedestrian Crashes with Turning Vehicles at Signalized Intersections

This seminar presents research findings and practical strategies for reducing pedestrian conflicts with turning vehicles at signalized intersections. It examines leading pedestrian intervals, No Turn on Red treatments, restrictions on permissive left turns, and automated pedestrian detection technologies. Drawing on a comprehensive literature review, interviews with transportation professionals, and field testing at seven intersections, the seminar highlights the safety effectiveness of individual and combined countermeasures. It also presents implementation guidelines and a practical toolbox to help transportation agencies select appropriate, site-specific treatments for improving pedestrian safety and advancing the FDOT Target Zero Initiative.
