It has great practical significance for optimizing emergency measures and enhancing urban rail transit system's operation to analyze the impact level of passenger flow under emergency. The preprocessing process of AFC card swiping data is given to facilitate the study on the disruption impact patterns. Two evaluation indicators, namely the deviation rate of inbound and outbound passenger flow and the deviation rate of OD(i.e. origin and destination) passenger flow, as well as their calculation methods, has been proposed. Analysis model based on passenger flow deviation rate was constructed by identifying affected stations and OD pairs. Based on practical cases, the impact level of affected stations and the spatiotemporal impact under emergencies at other stations were analyzed. Small emergencies have a relatively small impact on inbound passenger flow, but a significant impact on outbound passenger flow. The OD passenger flow at the terminal located in the commercial and work areas is more significantly affected. There is a significant correlation between the passenger flow deviation rate and the location of the station where the emergency occurred.
