考虑旅客跨车厢行为的动车组人员疏散仿真

Simulation on High-speed Train Carriage Evacuation Considering Passengers Moving to Adjacent Carriages

为研究旅客跨车厢行为对动车组人员疏散情况的影响,建立考虑出口选择的元胞自动机模型。以CR400BF型动车组二等车为研究对象,使用疏散效率、冲突次数和过道拥堵程度等指标,研究旅客跨车厢现象对车厢疏散的作用,并讨论旅客座位分布、相邻车厢转移旅客数量与车门开启方式等因素对疏散情况的影响。仿真结果表明:离散的位置分布使冲突次数减少约44.7%;旅客跨车厢疏散会降低本车厢旅客疏散效率;相邻车厢转移旅客数量与本车厢旅客疏散时长呈先线性增大后趋于稳定的关系;相邻车厢不同车门开启方式对本车厢旅客疏散效率的影响不同。

To study the influence of passengers moving to adjacent carriages on high-speed train carriages'evacuation,a cellular automata model considering export selection is established.Taking the CR400BF second-class carriage as the research object,some analytical indexes such as evacuation efficiency,number of conflicts and the congestion degree are used to study the effect of passengers moving to adjacent carriages on carriage evacuation,and the passenger seat distribution,the number of passengers transferred from adjacent carriages and the opening door modes of adjacent carriages are discussed.The simulation results show that the discretized seat distribution reduces the times of conflicts by approximately 44.7%.Evacuations of passengers moving to adjacent carriages reduce the evacuation efficiency of the carriage.The evacuation time of passengers in the carriage first increases linearly with the increase of the number of the number of moving passengers from adjacent carriages and then tends to be stable.Different door opening modes of adjacent carriages have different effects on evacuation efficiency.
