Optimization Method for Public Transport Priority Control at Signalized Intersection Influenced by Upstream Stop 2020-01-5160

With the increase in the number of cars in cities, traffic jams occur frequently, especially between upstream stops and intersections. As a means of transportation, public transport can effectively improve the efficiency of travel. However, the current research on the optimization of bus priority signal timing at intersections does not systematically consider the impact of the upstream bus stops at the intersection. In this regard, the article starts from the impact of upstream bus stops on the priority control of intersections, uses total passenger delay as the control standard, and builds an intersection bus priority signal timing model that considers the influence of upstream stops to extend the time by optimizing the green light to achieve the optimization of the bus priority signal timing scheme at the intersection. On this basis, the article selects the Qingliangmen Street-Nenjiang Road intersection and the Zhanjiang Road bus station as the control area, and conducts data collection. Using the measured data, the control area intersection bus priority signal control optimization model is calibrated and verified, and VISSIM software is used for simulation to verify the applicability of the model. The results show that after the optimization of the new model, the total delay of passenger travel is effectively reduced by 11.02%, which improves the travel efficiency of public transport vehicles at intersections. The research results will provide support for the improvement of the relevant theories for the optimal signal control of public transportation at intersections, and will also provide a reference for scientific and effective urban traffic signal management.
