Improved Safety and Efficiency of Protected/Permitted Right Turns for Bicycles in the Pacific Northwest

The goal of the research is to develop an understanding of the safety and operational implications of using the FYA to indicate a permitted right turn, and to provide general guidance as to when Protected/Permitted Right Turn (PPRT) phasing should be used to maximize the safety of non-motorized road users and the overall efficiency of signalized intersections in the Pacific Northwest. This goal is consistent with the PacTrans theme of Safe Travel on Mixed-Use Roads as the primary focus is to improve the safety of pedestrians and bicyclists in close proximity turning vehicles at signalized intersections. This project is also of regional importance as the Pacific Northwest has been an early adopter of the FYA for Protected/Permitted Left Turns (PPLT), with states like Oregon installing hundreds and hundreds of FYAs since the early 2000s. Based on the positive outcomes of PPLT phasing states in the Pacific Northwest are beginning to experiment with PPRT alternatives.
