    人群拥挤事件中的一种情绪感染仿真模型研究

    An Emotion Contagion Simulation Model for Crowd Events

    • 摘要: 随着我国城市化进程的推进,制定人员密集场所的非常规应急预案具有重要的现实意义.在人群拥挤事件发生时,事发人群的行为特征有别于正常的人群,容易导致人群陷入消极情绪.已有的人群仿真方法未能充分考虑人群个体之间的情绪感染,对人群拥挤的极端后果缺少研究.以火车站站台人群拥挤情景为研究对象,采用智能体的思想,提出了个体在情绪影响下的行为描述,根据人群中是否存在管理人员,提出了一种情绪感染计算方法.在计算机上编制了人群情绪感染仿真演示原型系统,对人群中的情绪感染、避碰、跌落等行为实现了三维情景仿真演示.实验结果表明,人群的消极情绪不仅与初始的情绪分布有关,也与管理人员的数量以及分布位置有关,控制人群中的消极情绪感染是避免人群拥挤事件的重要环节.

       

      Abstract: With the advancement of the process of urbanization in China, making unconventional emergent plan for dense crowd has important practical meanings. In a crowd event, the behavior of crowd is different from usual crowd movement, which can easily lead to a panic crowd trample. Emotion contagion among individuals is considered insufficiently in current crowd simulation methods; there is little research on extreme consequences for human crowd. A train station is selected as the example of study, and individual behavior with emotion is modeled in intelligent agent method. The details of calculation methods of emotion contagion are presented depending on whether there are administrators in the crowd. A prototype system of crowd emotion contagion is built, the 3D scene simulations for emotion contagion, collision avoidance and fall behavior are realized. The experimental results show that the negative emotion of crowd is related to not only the initial emotion distribution, but also the numbers and locations of administrators, so controlling the crowd negative emotion contagion is an important method of preventing crowd events. Users can adopt the model to reveal the emotion contagion in visualization manner, and the model can be further extended to other simulations of crowd scenes.
