Bicyclists vs. Right Turn Vehicles: Optimizing Design Based on Conflict Risk Data
While protected bike lanes are very safe for users while cycling behind the protection, cyclists must cross intersections where there is no physical protection. Between 2014 and 2016, 44% of bicyclist fatalities in urban areas occurred at intersections. Of the intersection fatalities during that period, vehicle right turn vs bicyclist in the same direction ("right hook" crashes) were listed in the Top 7 most common crash types. There is a lack of data on crashes and on near-misses to inform facility design. This project is seeking to quantify the safety effects of intersection design treatments recommended in national guidance and evaluate other key contextual elements known to impact bicyclist safety by studying the frequency and severity of detected conflict events. This study is being done in collaboration with other North American cities to conduct similar, parallel studies so that findings can be shared and generate a database for future research.
