Coordinated control method for trams on urban arterial

Abstract

To improve the operation efficiency of the trams on the arterial, a green-wave coordinated control scheduling method for trams at intersections is proposed. The influence of the tram on the green wave programming model is analyzed, and the calculation formula of the intersection distance in the programming model is amended. Tram priority signal control system is introduced, including the absolute priority and the relative priority. Combined with these two priority schemes, according to the type of intersection and the time when the tram arrives at the intersection, the tram priority control strategy is designed. Then the position of the tram detector is studied. According to the regularity of tram's operation, the appropriate interval between the departure times of trams is proposed to prevent multiple trams arriving within the same traffic signal period. Finally, the microscopic traffic simulation software VISSIM is used to establish the coordination control model of the tram line in Huaian city, in order to validate the proposed method.
