How to provide the bridge service for the affected passengers from the existing bus stations or the first and last stations to the interrupted railway stations is the necessary means to improve the emergency management level and the service reliability of the urban public transport system. This paper mainly analyzes how to transfer the nearby public transportation in the time of the interruption of the rail transit operation and quickly evacuate the passenger flow at the interruption point and establish the optimization model of the bus connection.
