An Active Transit Signal Priority Method Considering Short-Term Prediction Error

Abstract:

To improve the competitiveness of public transport， and aimed at eliminating the parking and waiting time in the intersection of buses， an active TSP （transit signal priority） method for short distance intersections is proposed， which takes the bus arrival prediction error into consideration， and fairly shares green losses or gains according to the criterion of the minimum signal deviations. Simulation experiments are designed and conducted to verify the effectiveness and applicability of the method. The results of the effectiveness experiments show that the proposed method decreases the parking and waiting time of buses by 90.8%， and outperforms the other three control methods with a 3.01% drop in per capita delays. The results of applicability experiments show that the proposed method is applicable for signalized intersections with a degree of saturation of no more than 0.8.
