在地铁突发事件的背景下,从信息视角分析了群体恐慌情绪的产生和传播过程;之后借鉴经典的SIS传播模型构建了一个恐慌情绪传播模型,以进一步分析突发事件中群体恐慌情绪形成的动力学规律。模型分析得到了恐慌情绪传播的临界值,发现提高政府公信力,提高应急信息发布的及时性、准确性和有效性,提高乘客的应急信息利用能力对控制恐慌情绪扩散有重要作用。
In the background of subway emergency, this paper analyzes the process of the generation and spread of panic in the perspective of information. Then, a model of panic transmission is constructed based on the classic SIS transmission model to further analyze the formation of panic in the emergency Dynamic laws. The model got the critical value of panic spread, and found that improving the credibility of the government, improving the timeliness, accuracy and effectiveness of emergency information release and improving the ability of passengers to utilize emergency information have an important role in controlling the spread of panic.
