Model considering panic emotion and personality traits for crowd evacuation

Chinese Physics B 2023年第5期32卷 321-336页

作者：孙华锴陈长坤 Institute of Disaster Prevention Science and Safety Technology Central South UniversityChangsha 410075China

Panic is a common emotion when pedestrians are in danger during the actual evacuation, which can affect pedestrians a lot and may lead to fatalities as people are crushed or trampled. However, the systematic studies and quantitative analysis of evacuation panic, such as panic behaviors, panic evolution, and the stress responses of pedestrians with different personality traits to panic emotion are still rare. Here, combined with the theories of OCEAN(openness, conscientiousness,extroversion, agreeableness, neuroticism) model and SIS(susceptible, infected, susceptible) model, an extended cellular automata model is established by the floor field method in order to investigate the dynamics of panic emotion in the crowd and dynamics of pedestrians affected by emotion. In the model, pedestrians are divided into stable pedestrians and sensitive pedestrians according to their different personality traits in response to emotion, and their emotional state can be normal or panic. Besides, emotion contagion, emotion decay, and the influence of emotion on pedestrian movement decision-making are also considered. The simulation results show that evacuation efficiency will be reduced, for panic pedestrians may act maladaptive behaviors, thereby making the crowd more chaotic. The results further suggest that improving pedestrian psychological ability and raising the standard of management can effectively increase evacuation efficiency. And it is necessary to reduce the panic level of group as soon as possible at the beginning of evacuation. We hope this research could provide a new method to analyze crowd evacuation in panic situations.

基于模拟创伤研究范式，采用道路交通事故影片对159名健康大学生进行模拟创伤，考察PTSD易感性人格特质(特质焦虑、特质分离和神经质)、工作记忆能力(注意控制和工作记忆容量)和创伤期间认知加工(数据驱动加工和概念加工)对模拟创伤后... 详细信息

基于模拟创伤研究范式，采用道路交通事故影片对159名健康大学生进行模拟创伤，考察PTSD易感性人格特质(特质焦虑、特质分离和神经质)、工作记忆能力(注意控制和工作记忆容量)和创伤期间认知加工(数据驱动加工和概念加工)对模拟创伤后不同时段闪回的影响。运用结构方程模型分析数据，结果发现：(1)数据驱动加工正向预测不同时段闪回(即时闪回、一周闪回和触发闪回)的数量、生动性、痛苦度以及一周侵入频率；(2)神经质正向预测触发闪回痛苦度，注意控制和工作记忆容量负向预测一周侵入频率；(3)概念加工在注意控制与即时闪回痛苦度之间起中介作用。研究结果提示：数据驱动加工是创伤后不同时段闪回的主要影响因素；概念加工主要作用于早期急性应激反应，注意控制是其保护因素；神经质和工作记忆能力对闪回具有较长期的影响，且工作记忆能力具有一定的保护作用。
