With the rapid economic development of China's big cities and the continuous increase of urban passenger flow, how to guide the safe and efficient evacuation of personnel in the case of large passenger flow，it has become the focus of attention in the industry. The evacuation behavior of passengers is affected by their own physical and psychological factors as well as the external environment. During the evacuation process, panic factors are an important factor affecting people's behavior, people's panic state is not just a static fixed value, but a transitive and iterative process. Firstly，logistic regression was performed on the data in the social questionnaire, and get the coefficients of various impact indicators; Secondly, based on system dynamics, established a panic diffusion model during the evacuation of the bus passenger station, and the degree of influence of various factors on the evacuation capacity of the bus passenger station is obtained using this model; Finally, the sensitivity analysis of the model is carried out to obtain suggestions for the evacuation process of the station, which provides a reference for optimizing emergency evacuation in the future.
