基于交叉口信号优先的有轨电车车速引导控制模型及实现方法的研究

摘要

针对有轨电车运行效率受城市道路交叉口影响的问题,在分析交叉口多种交通方式混行的复杂性基础上,考虑有轨电车特性、道路环境以及交叉口信号优先控制等因素,以减少有轨电车交叉口的停车延误为目标,构建有轨电车车速引导控制模型,并提出对应的实现方法.通过VISSIM及对COM口的二次开发,将提出的模型嵌入仿真系统,并对实际控制效果进行仿真验证分析.结果表明,该模型能有效减少有轨电车交叉口的停车比例和停车延误,对社会车辆的影响较小.%In response to the impact of the urban road intersection on the operation efficiency of trams,based on the analysis of the complexity of mixed various traffic modes at intersections,considering tram characteristics,road conditions and signal priority control at intersections.A tram speed-guidance algorithm and corresponding implementation method was proposed,with the reduction of tram stop and delay at intersections as the objective.A simulation platform was constructed through the use of VISSIM and extended development of its COM interface to verify its practical control effects.The simulation results showed that the model can effectively reduce the delay time and stopping proportion of tramcars at intersections while having little impact on other vehicles.
