Study on Information Release of Urban Rail Transit Passenger Flow Induced under Emergencies

Urban rail Transit system is a dynamic, uncertain and complex system, it will seriously affect the traffic capacity of road network, and the convenience of people's travel in the event of emergencies. So the timely and accurate release of information is an important guarantee of the safe and efficient operation of rail transit. At first, the problems, which existed in the process of releasing information of the rail transit passenger flow guidance under emergencies are analyzed,. Then the functional structure of the system is designed. Based on the structure, this paper does a research on the process of the information release, and puts forward the calculation method in a general influencing scope. Combined with examples, the detail processes of the information release of urban rail transit passenger flow under emergencies are illustrated.
