城市轨道交通车站大客流疏散方法研究

Study on Evacuation Method of Large Passenger Flow in Urban Rail Transit Station

在我国城市人口不断增多、地面交通压力不断增加的背景下,城市轨道交通系统因为拥有独立路权逐渐成为城市交通的主动脉,然而城市轨道交通车站在面对日常高峰情况和突发紧急情况时的疏散能力还明显不足。针对上述问题,本文设计了常态大客流疏散模型和突发大客流紧急疏散模型,并运用AnyLogic软件对济南地铁创新谷站进行仿真,在常态大客流疏散模型中,通过添加事件智能体,可以同时模拟出候车区的乘客上车完成疏散和列车内的乘客下车产生大客流这一过程;在突发大客流紧急疏散模型中添加新的板块,添加自动寻找自动出口函数和设置突发事件按钮来模拟乘客进行正常进出站流程。通过案例分析可以看出,在常态化大客流情况下,添加新模块的客流疏散模型,疏散效率较既有疏散方案有着显著提升,同时为应对突发性大客流情况提出了相应措施,进而保证济南城市轨道交通更加平稳有序运行。

Under the background of increasing urban population and increasing ground traffic pressure in China,urban rail transit system has gradually become the main artery of urban traffic because of its independent right of way.However,the evacuation capacity of urban rail transit stations in the face of daily peak and emergency situations is still obviously insufficient.To solve the above problems,this paper designs the normal large passenger flow evacuation model and the emergency large passenger flow evacuation model,and uses AnyLogic software to simulate the innovation valley station of Jinan Metro.In the normal large passenger flow evacuation model,the process of passengers getting on the train to complete evacuation and passengers getting off the train to generate large passenger flow can be simulated simultaneously by adding event agents;A new section is added to the emergency evacuation model to simulate the normal flow of passengers in and out of the station by adding the automatic exit finding function and setting the emergency button.It can be seen from the case analysis that in the case of large normalized passenger flow,the passenger flow evacuation model with new modules has significantly improved the evacuation efficiency compared with the existing evacuation plan.At the same time,relevant measures have been proposed to deal with sudden large passenger flow,so as to ensure a more stable and orderly operation of Jinan urban rail traffic.
