Research On Capacity Of Urban Rail Transit Transfer Station Facilities

With the development of Chinese economy,the construction of urban rail transit has entered a stage of rapid development.At present,there are 44 cities striving to build a rail transit system in China,with a total mileage of 6,730.27 kilometers.Many cities in China have entered the stage of network operation of rail transit.Rail transit attracts a large number of passengers due to its large volume,fast speed,convenience and comfort.The transfer station has become an important node of the line network.The passenger flow in the rail transit transfer station is large,but at the same time the capacity of some station facilities is difficult to meet the needs of passengers.Therefore,it is necessary to analyse the traffic capacity and match situation of the station facilities.In view of these problems,this article will carry out in-depth research.This article first analyses the performance of urban rail transit interchange stations and their functional positioning,introduces the classification of stations,the functions of interchange stations,and the advantages and disadvantages of various transfer modes;and from the individual characteristics of pedestrians and the speed,density,and flow of pedestrians at the micro level,analyse the traffic characteristics of pedestrians,and at the macro level,the spatial and analyse temporal distribution characteristics of passenger flow in rail transit interchange stations.Secondly,the analysis of the facilities in the rail transit interchange station defines the main research object of this article,that is,the transfer facility is the main research object,and the facility design and capacity calculation methods are studied.It also analyses the influencing factors of the capacity of the facility from the aspects of passenger behavior and the relationship between the facilities.It also defines the facility capability matching,and analyses the facility matching from facility saturation,matching rationality,and facility service efficiency.Taking the Zijingshan Station of Zhengzhou Metro as an example,through the field investigation,the pedestrian flow characteristics of the rail transit interchange station are analysed,and then the passing capacity of the interchange facility is calculated to realize the matching assessment of the Zijingshan interchange station facility.According to the field survey data,the simulation parameters are set up,and the Anylogic pedestrian simulation model based on the social force model is established to simulate and analyse the pedestrian walking process in the rail transit interchange station.Aiming at some problems in the transfer system of Zijingshan Station,the simulation model is used to optimize the analysis,and propose corresponding improvement measures.
