Study On The Large-scale Passenger Flow Distribution Organization Of Urban Rail Transit Transfer Station Based On LEGION Simulation Technology

As an important note of rail transit network,transfer stations of urban rail transit have many characteristics,such as complex building structures,high and concentrated passenger volume etc.Effect of passenger organization directly affects transfer stations’ ability to transport in the face of peak passenger flow,the efficiency of operation and management and the level of services.It is of practical significance to organize passenger flow and transportation in a safe,efficient,stable,and orderly manner.In this paper,based on the characteristics of pedestrian traffic,the structure of transfer stations and the characteristics of passenger flow during peak hours,combined with the actual operation of large transfer stations,this paper proposes a regional passenger transfer organization method for mass passenger flows.(1)This paper studies selectivity of pedestrian routes and selection probability and conditions for stairs and escalators at super-large transfer stations with special building structures.(2)Based on the traffic characteristics of pedestrians in the super-large transfer station,a simulation model of large-scale passenger flow and evacuation organization during peak hours based on LEGION simulation technology was established.(3)This paper analyzes and compares the organization plan of large passenger flow evacuation during peak hours at transfer stations,and proposes a method that for evacuation.(4)Using the constructed simulation model of large-scale passenger flow transportation organization,by comparing the output data of passenger flow density,passenger number of congestion at key nodes,transfer time during peak hours,the applicability of the new passenger transfer organization method which take different transfer plan according to characteristics of different regions is qualitatively analyzed and verified.(5)The results of simulation show that the new passenger transfer organization method can effectively improve the service level of large-scale passenger traffic during peak hours in areas of transfer stations.It can provide a reference for the organization and operation management of large passenger flow of transit stations.There are 63 figures,16 tables,and 67 reference documentations in the article.
