地铁站出口宽度对人员疏散时间影响的仿真分析

利用Anylogic行人库,通过建立火灾发生时的行人疏散微观仿真模型,考察地铁站安全出口的宽度设置与人员疏散时间之间的对应关系.研究发现,同一到达速率下,人员疏散时间随安全出口宽度的增加呈现递减趋势;出口宽度增加到临界安全出口宽度时,再增加出口宽度,疏散时间趋向一定值;不同到达速率下,人员密度较高的情况下,出口宽度的增加对疏散时间的影响比人员密度较低的情况下更加明显.

Simulation Analysis on the Influences of Subway Exit Width on Pedestrian Evacuation Time

To analyses the corresponding relations between subway station exit width and pedestrian evacuation time, a microscopic simulation model of pedestrian evacuation when the fire broke out is established based on Anylogic pedestrian library. Studies found that under the same arrival rate, personnel evacuation time decreasing with the increase of safety exit width; and when exit width increases to a critical safety exit width, then increase the exit width, evacuation time tends to a certain value;under different arrival rate, influence of the increase of exit width on evacuation time is more obvious than low density case in the condition of high personnel density.
