Abstract:

When drivers make left turns during a permissive turn phase, they must yield to pedestrians as well as oncoming through vehicles. Left-turning drivers sometimes overlook pedestrians in the crosswalk while watching the opposing intersection approach. Implementing a protected left-turn phase can reduce or eliminate the potential conflict between pedestrians and left-turning vehicles, but is likely to increase vehicular delay. The potential benefit of reduced pedestrian-vehicle crash costs must be weighed against the expected increase in delay costs. The Traffic Signal Operations Handbook, Second Edition contains guidelines for choosing left-turn operational mode (protected, protected-permissive, or permissive) based on considerations of both pedestrians and vehicles. A spreadsheet program called Texas Signal Coordination Optimizer (TSCO) is available to assist practitioners in the application of these guidelines by automating the complex calculations. A training course was developed to facilitate implementation of these tools, and seven presentations of the course were provided at various TxDOT venues.
