人员恐慌行为下闸机和自动扶梯疏散效率研究

介绍人流恐慌行为模拟模型社会力模型,分别分析人员恐慌行为对闸机疏散效率和自动扶梯疏散效率的影响,认为期望速度为约1.5m/s时,闸机疏散时间最短,随着期望速度的增大,疏散时间增加,闸机通行能力降低,若人员表现出恐慌行为,闸机和自动扶梯口的疏散效率分别为有序疏散的50%和70%。该结果对地铁设计规范的制定及地铁站设计具有指导意义。

Study on evacuation efficiency of ticket gate and escalator under panic behaviour

The social force model, which is a simulating model of people flow under panic behavior, is introduced. The evacuation efficiencies of ticket gate and escalator are analyzed separately. Results show that the evacuation time of ticket gate is shortest when the expecting speed is 1.5 m/s, and the evacuation time increases as the expecting speed increases, while the traffic capacity of the ticket gate depresses; the evacuation efficiency of ticket gate and escalator under panic behavior is 50% and 70% of that ...
