摘　　要：应用系统仿真的方法,建立了突发事件下的城市轨道交通列车运行仿真模型,并应用北京地铁亦庄线的实际数据进行了案例分析。基于离散事件模型的仿真方法,使用Processing和G4P控件库开发仿真软件,实现列车的超速防护、移动闭塞系统生成列车移动授权、列车运行控制和列车停站控制。通过系统仿真,针对城市轨道交通单线多列车的运行场景,对突发事件下的全线运行、延误情况进行模拟和评估。结果表明,故障发生的不同位置和持续时间会对列车延误情况造成不同影响,并且通过运行调整手段如发车调整和停站调整可以有效缓解突发事件下列车的延误情况。In this paper,a system simulation method is established to simulate urban rail transit operation in the event of an emergency.Based on the actual data of Beijing Subway Yizhuang Line,we developed a simulation software by using discrete event model,Processing and G4P library.Functions include overspeed protection,train speed authorization generation,train movement control and train station control are realized.We simulated and evaluated the running scenarios of multiple-train operation on a single urban rail line and its delay conditions in an emergency event.Results showed that urban rail transit had different delay consequences when an emergency event happened at different positions or different time intervals;furthermore,those delay consequences could be relieved effectively through different operation adjustments like changing train departure and dwelling intervals.
