A Data Driven Safety Assessment of Various Left Turn Phasing Strategies

This research will use a data-driven methodology to assess the safety of the aforementioned signalization strategies. The results of this research will help decision makers to select a more suitable signal phasing plan/display under various operational conditions. Specific objectives are: Compare the safety of protected left turns to protected-permissive left turns with FYA, Compare the safety of doghouse displays to four section vertical displays with Flashing Yellow Arrow (FYA), and Assess the safety of including FYA phases in protected-permissive left turns at different times of the day to identify if it creates driver confusion.
