人员聚集场所的拥挤踩踏事故，往往与意外事件造成的人群恐慌有很大的关系。在恐慌情绪的支配下，个体对环境的思考能力、对行为的决策能力都会降低，同时恐慌情绪会放大个体对危险源的排斥程度，个体会降低甚至放弃平时的一些运动特征，例如选择插队、推搡、对碰撞拥挤的忍耐程度提高等。个体的无序行为会导致人流的局部失稳，进而引发踩踏事故并最终蔓延影响整个群体。因此研究恐慌行人流的疏散对安全管理很有意义。然而，目前对恐慌行为的研究局限于对恐慌因子的人为设定和定性研究，缺乏对疏散人群恐慌心理的客观、定量分析。本项目从生理数据入手，通过采集疏散过程中的脑部信号，间接得到个体的心理状态，结合实验前后的问卷调研，实现对疏散过程中恐慌情绪的定量化研究，并在此基础上研究恐慌情绪的动力学作用机理和个体间的恐慌情绪传播机制，提出行之有效的恐慌情绪传播阻断方式，用于实际的疏散管控。

Crowded stampede accidents are often associated with crowd panic caused by accidents. Under the control of panic, individuals' ability to think about the environment and their ability to make decisions will be reduced. At the same time, panic will amplify their rejection of the source of danger. Individuals will reduce or even give up some of the usual evacuation characteristics, such as choosing to cut the queue, pushing, increasing tolerance for collisions and so on. The disordered behavior of individuals can lead to local instability of the flow of people, which in turn leads to stampede accidents and eventually spreads affecting the entire group. Therefore, studying the evacuation of panic pedestrian flow is very meaningful for safety management. However, the current research on panic behavior is limited to the artificial setting and qualitative research of panic factors, and lacks objective and quantitative analysis of panic psychology of evacuated people. This project starts from the physiological data, indirectly collects the mental state of the individual by collecting the brain signals in the evacuation process, and combines the questionnaire survey before and after the experiment to realize the quantitative research on the panic emotion in the evacuation process, and on this basis, research the dynamics mechanism of panic and the mechanism of panic sentiment between individuals to propose an effective way to block the spread of panic emotions for practical evacuation control.
