This study attempted to provide insight on causes of left turn crashes at signalized intersections with special attention to protective, permissive, protective/permissive, and permissive/protective left turn phasing schemes. The approaches used in this study involved collecting and analyzing crash data and conducting traffic conflict studies at selected intersections. Although the traffic crash database proved to be reliable for certain applications, it is inadequate to establish statistical correlation between traffic crashes and the traffic signal indication. The traffic conflict studies conducted in this project showed that this technique appears to be promising and could be used as a safety surrogate. Furthermore, the results indicated that the permissive/protective scheme appears to provide safer traffic conditions than the protective/permissive scheme.
