摘要
为了反映恐慌情景下行人疏散的变化规律,基于Anylogic软件进行仿真分析.通过引入情绪因子和信息因子,量化恐慌传播系数和信息传播系数,建立群体恐慌动力学模型,运用蒙特卡洛等方法进行群体心理的量化分析,划分恐慌程度等级为Ⅰ级、Ⅱ级、Ⅲ级、Ⅳ级、Ⅴ级.运用该模型分析不同密度、不同恐慌等级下的恐慌人员疏散规律.研究结果表明:低密度情景下恐慌对疏散效率的影响较低,中、高密度情景下,适度恐慌可以降低疏散时间,超出临界范围会导致疏散的延缓.场景模拟可以看出,适度恐慌下人员疏散迅速有序,相反,过度恐慌下人员疏散缓慢混乱.
Abstract
In order to reflect the changing pattern of pedestrian evacuation in panic scenarios,simulation analysis was conducted based on the AnyLogic software.By introducing emotional fac-tors and information factors,quantifying panic transmission coeffi-cients and information transmission coefficients,establishing a group panic dynamics model,and using Monte Carlo methods for quantitative analysis of group psychology,the panic level is di-vided into five levels:Level I,Level II,Level III,Level IV,and Level V.This model is used to analyze the evacuation pattern of panic-stricken people under different densities and panic levels.The results show that panic has a low impact on evacuation effi-ciency under low-density scenarios,and moderate panic can re-duce evacuation time under medium-and high-density scenarios.Exceeding the critical range can lead to a delay in evacuation.The scene simulation shows that under moderate panic,the evacuation of people is rapid and orderly,while under excessive panic,the evacuation of people is slow and chaotic.
