基于Vissim仿真的有轨电车应急方案设计

The Design of the Tram Emergency Plan Based on the Vissim Simulation

文章借鉴有轨电车运行问题已有成果,分析突发事件对有轨电车运行情况的影响,并在此基础上提出突发事件下有轨电车运行控制方法。在控制模型中,根据应急车辆的到达时间和消散时间估计来选择最优控制策略;对有轨电车,根据每一辆车的当前运行状态来确定不同的控制策略。根据文章建立的模型结合Vissim软件对案例进行模拟仿真,验证方法的有效性。

The achievement based on streetcars running problems, analyzing the emergency influenced on streetcars running situa-tion, and basing on this, advances the streetcars running under emergency control method, the control model adopted the principleof absolute release of emergency vehicle; For trams, determined different control strategies based on the current operating state ofeach vehicle. Based on the model set up in this paper, Vissim software is used to simulate the case and verify the effectivenessof this method.
