The overall goal of this project is to provide appropriate safety performance functions for different types of restricted crossing U-turn (RCUT) intersection for use by Florida Department of Transportation (FDOT) planners and engineers at various levels of project development and safety analysis. Consistent with this goal, the main objectives of this project are: (a) to collect geometric, traffic and crash data from a sufficient number of existing RCUT intersections in the United States; (b) to determine significant factors influencing the RCUT intersection safety; and (c) to develop, calibrate, and validate safety performance functions (SPFs) for RCUTs with different characteristics (urban/rural, unsignalized/signalized, etc) base don the collected data. |
