Development and Evaluation of Transit Signal Priority Strategies

Research on the effectiveness of providing signal priority to transit vehicles is presented in this report. Results from previous studies indicate the effectiveness of transit signal priority depends on a number of factors, including the type of transit route, the level of transit usage, and the time of day priority is used. This research describes and evaluates several methods for providing transit signal priority during both peak and off-peak times.
Results indicate that providing signal priority during off-peak times is often justified, due to the excess capacity available within the transit network. However, during peak times, use of transit signal priority is only justified when the level of transit usage is high.
