Improving Transportation Network Efficiency Through Implementation of Transit-Supportive Roadway Strategies

This report documents the research conducted by TCRP Project A-39, Improving Transportation Network Efficiency Through Implementation of Transit-Supportive Roadway Strategies. This project conducted an extensive review of transit preferential treatments used in the U.S. and internationally, including information on when these treatments are applied and how they are designed. The project interviewed a number of transit and roadway agencies to identify lessons-learned and best practices from actual project implementations, with a particular focus on successful techniques for transit agencies, roadway agencies, and project stakeholders to work together toward outcomes that benefit all parties involved. This report also presents findings from a series of gap-filling research efforts on (1) innovative international strategies not yet in common use in the United States; (2) a simulation study of the effects of stop location, transit signal priority, and queue jumps on bus and general traffic travel times and travel time variability; (3) an evaluation of selected strategies implemented in the Seattle area; and (4) identifying conditions when the delay benefit produced by a strategy at an upstream intersection is lost at the next downstream signal, resulting in no net benefit. Finally, this report presents recommendations for changes to the next edition of AASHTO’s Guide for Geometric Design of Transit Facilities on Highways and Streets, based on the findings of this project.
