Understanding the Nature of Broadside Crashes at Signalized Intersections and Developing Strategies to Address Them

The intent of this project is to develop better understanding of broadside crashes and develop strategies to reduce them. The work will include development of Safety Performance Functions (SPF) for broadside crashes at signalized intersections and network screening of all intersections using new SPFs. Following network screening using new broadside SPFs it would become possible to identify which intersections experience unusually high (LOSS-IV) or unusually low (LOSS-I) number of broadside crashes. The aim here is to identify factors that contribute to broadside crashes at signalized intersections by examining their operational and geometric characteristics.
