从网络层面出发,将列车运行过程仿真与客流出行过程仿真结合在一起,研究城市轨道交通正常运营及故障应急处置过程的微观仿真问题。通过分析仿真系统的类结构、事件驱动模型的建立和仿真算法的总体流程等内容,设计开发了应急处置微观仿真系统,并以列车故障救援为例,对其处置过程的影响和效率进行了对比评价。采用微观仿真技术,可将完整的网络客运过程再现,实现精细化统计列车运行和乘客出行相关的时间和效率指标,为轨道交通突发事件应急处置方案的分析、决策和评价奠定坚实的基础。
Setting the view of network level, and combining train operation process simulation with passenger travel process simulation together, this paper researched the microcosmic simulation problem of urban rail transit normal operation and emer- gency treatment process. By analyzed the simulation system' s class structure, the event-driven model and the system' s algo- rithm process, this paper developed the urban rail transit emergency treatment microcosmic simulation system, and took train breakdown rescue for example to evaluate the disposal process' s effect and efficiency. The microcosmic simulation technology, could recur the whole network passenger transport process, achieve fine statistical train operation and passenger traveling time and efficiency index, and to lay a solid foundation for urban rail transit emergency treatment scheme' s analysis, decision- making and evaluation.
