基于VISVAP的有轨电车信号优先控制仿真

Priority Control Simulation of Tram Signal Based on VISVAP

为避免有轨电车通过交叉口时对其他交通方式产生干扰,可采用有轨电车优先信号控制的方法。以VISSIM仿真系统中的VISVAP模块作为仿真信号控制工具,在交叉口对未运行有轨电车、运行有轨电车和设置有轨电车信号优先的3种状态进行仿真,并以延误作为主要参数来评价有轨电车信号优先控制对交叉口运行产生的影响。仿真结果表明,用VISVAP模块对有轨电车进行优先信号控制仿真较为可靠,能为有轨电车线路规划及项目实施的可行性分析提供技术支持。

In order to avoid obstruction of other modes of transport when the tram passes through the intersection, the method of priority control of tram signal can be adopted. The VISVAP module in VISSIM simulation system is used as the simulation signal control tool to simulate the three states of the tram not operating at the intersection, the tram operating at the intersection, and the tram under signal priority respectively. Delay is then taken as the main parameter to evaluate influence of priority control of tram signal on the operation of the intersection. The simulation results show that it is reliable to use the VISVAP module for the priority control of tram signal, and the simulation can be a source of reference for technical support for tram route planning and the feasibility analysis of implementation of tram project.
