Title: Efficiency Analysis of Transit Signal Priority Strategies on Isolated Intersection
Abstract: Giving buses priority at isolated intersections is an efficient and realizable approach to decrease bus delay. Three bus priority strategies were proposed: green extension, red truncation and phase insertion. The delay triangle was used to build bus delay models and no-priority phases delay models under different priority strategies. Two indexes: bus delay and no-priority phases delay were adopted to evaluate the efficiency of each bus priority strategies. And a series simulation was done to validate the resolutions. The results of the models and simulations show that delay of buses can be decreased by the three priority strategies while increasing delay of no-priority phase movements. The efficiency of red truncation is much higher than that of green extension. And the efficiency of phase insertion is relevant with the proper inserting time, saturation of bus lane and other factors.
