Abstract:
For intersections with a permissive or protected-permissive left-turn mode, pedestrians cross during the permissive period. This operation requires the left-turn driver to yield to both opposing vehicles and pedestrians, prior to accepting a gap and completing the turn. Pedestrian crash risks are increased in these complicated driving conditions because left-turn drivers sometimes fail to yield to pedestrians. Guidelines for the selection of left-turn mode (e.g., permissive, protected, and protected-permissive) have historically focused mainly on vehicular traffic conditions at the intersection. These workshop materials provide guidelines for selecting left-turn operational mode based on consideration of pedestrian safety and vehicle operation. These considerations include the road-user costs associated with pedestrian-vehicle crashes and vehicle delay. The workshop materials also provide guidelines for identifying pedestrian safety treatments. An updated edition of the Traffic Signal Operations Handbook, which provides guidance for timing and designing traffic control signals at intersections that operate in isolation or as part of a coordinated signal system, is included with the materials
