Abstract: For the passenger evacuation problem of urban rail transit stations under emergencies, considering the incomplete rational decision-making behavior of passengers, an evacuation passenger flow assignment method based on prospect theory is proposed. The internal structure of the station is first networked into a directed graph, and the effective path set is obtained by the depth-first-search algorithm in turn. Then, considering the incomplete rational behavior of passengers, an evacuation passenger flow assignment model based on prospect theory is established, and the method of successive averages is used to solve the model. Finally, taking the Chengdu Taisheng South Road subway station as an example, an emergency evacuation scenario is set up for model application, and AnyLogic is used to simulate the distribution results based on the prospect theory, and the distribution results based on the user equilibrium theory, which assumes passengers are completely rational. The results show that the distribution results obtained by the passenger flow assignment method based on the prospect theory are more in line with the actual emergency evacuation results.
