Transmission Mechanism of Sudden Large Passenger Flow in Urban Rail Transit Network

According to the nature and characteristics of work on sudden large passenger flow in the urban rail transit stations,the stations in the urban rail transit network are divided into starting stations,transfer stations and intermediate stations.Based on this,considering the factors of passenger density in the station’s waiting area,surplus capacity for passengers of the arrived trains,the number of waiting passengers on the platforms and passengers’ boarding efficiency,the model of passenger density effect in the station’s waiting area and the model of delay time of train operation are built,and the transmission mechanism of sudden large passenger flow in the urban railway network is concluded.From two respects of station’s service level and effect of train operation,this paper analyzes the influencing factor of the transmission of the sudden large passenger flow and the corresponding adjustment measures.
