Abstract:

To evaluate the operational efficiency and emergency strategies of the trail transit under different passenger flow conditions, also simulate and analyze the emergency strategies quantitatively, a simulation platform for urban rail transit was proposed. This system modeled four main objects that consisted of the kinetic model of train, the Automatic Train Control (ATC), the trackside equipment and the moving block system. On this basis, the whole simulation system was designed and implemented based on VC〖KG-*3〗+〖KG-*3〗+ development platform combined with computer network and database technology. Finally, the operation of the train was able to be automatically implemented on this simulation platform driven by the train timetable. The system was assessed by using the data of the rail transit of Shanghai 8th line and the simulation results show good consistency with the real timetable.

Key words: rail transit, simulation platform, modeling, object oriented, Automatic Train Control (ATC)

摘要：

为研究不同客流状况下轨道交通的运行效率和应急方案效率评估,以及突发事件下应急策略的仿真和定量分析,提出了一种城市轨道交通运行仿真平台。该系统从列车运动模型、自动列车控制(ATC)系统结构模型、轨旁设备对象功能模型和移动闭塞系统模型等4个方面对城市轨道交通运行仿真系统进行建模。在此基础上,以VC++作为开发平台,结合计算机网络以及数据库技术,设计并实现了完整的地铁运行仿真平台。在时刻表的驱动下,仿真平台可以实现列车的自动运行。该系统以轨道交通8号线数据进行验证,仿真结果与真实时刻表达一致。
