Safety Evaluation of Turning Maneuvers at California Intersections

This research will provide an evaluation of the safety of California intersections in a context-sensitive manner. Specific objectives of this project include: Analyze statewide collision data to identify infrastructure and/or community context(s) that contribute to conditions leading to crashes in intersections, including left turns, right-turns on red, etc. Based on the analysis of collision data, and deeper investigations using Google Street View, the research team will identify context-sensitive strategies based on the safe systems approach that can address the safety concerns. The strategies would include a prohibition of the maneuver and installation of protected intersections based on NACTO recommendations, among others.
