Simulation And Optimization Of Transfer Capacity Of Large Passenger Flow In Tianjin Urban Subway Traffic

With the continuous development of China’s large and medium-sized cities,the passenger flow of urban subway has shown an upward trend,and the subway transfer station has become a key node affecting the service level and operation efficiency of urban rail transit.Especially for the organization and management of large passenger flow in the peak period of subway transfer station,it is regarded as the key factor affecting its service ability and service quality.How to carry out the adjustment of passenger flow organization method on the basis of existing hardware facilities and improve the service capacity of transfer station is of great significance.This paper starts with the theories related to the transfer mode,facility capacity and service level of large passenger flow and subway transfer station,analyzes and summarizes the classification,identification basis and organization method of large passenger flow in urban subway,and analyzes various transfer modes and their characteristics.According to the relevant norms,the maximum capacity of various transfer facilities is obtained,and the classification of service level of urban subway transfer facilities by scholars is concluded.Then,taking the Hongqi South Road Station of Tianjin subway as an example,the paper carries out field investigation on Hongqi South Road station,obtains the passenger flow data of Hongqi South Road Station in peak period,and analyzes the passenger flow data,passenger flow characteristics and passenger flow streamline of Hongqi South Road station.According to the current situation of Hongqi South Road station,the classification standard of service level of transfer facilities in Hongqi South Road station is obtainedThen,Any Logic software is used to realize the establishment of passenger flow simulation model of Hongqi South Road Station,and carry out field research on the comparison of passenger flow data,so as to test the simulation model.The results show that the passenger flow data of the simulation model can simulate the passenger flow of Hongqi South Road Station in peak hours excellently,and the simulation model is very effective.According to the simulation results of the model,the service levels of facilities at Hongqi South Road Station in peak hours are as follows: service level of station hall is A;service level of platform of line 3 and line 6 is B;due to the high passenger flow density of transfer facilities,the service level is E.Finally,this paper puts forward the optimization scheme of passenger flow organization in the peak period of Hongqi South Road station,and implements the modification of simulation model.After the follow-up analysis and optimization,the transfer time and passenger flow density of transfer facilities are obtained.After optimization,the service level of transfer facilities is upgraded from E to C,which shows that the optimization scheme is feasible and effective.
