Study On The Influence Of One-platform Transfer On The Urban Rail Transit Network Features

With the acceleration of urbanization process in our county and the growing scale of urban rail transit network, urban rail transit in many cities has entered the network construction and operation stages. Network operation has brought a large number of transfer passenger flow, transfer problem is increasingly outstanding. Through plan the transfer station properly, improve the efficiency of the transfer, shorten the transfer distance and transfer time, the problems encountered in the transfer can be solved effectively, the development of urban rail transit will be smoother and more scientific.This paper summarizes all the methods of urban rail transit transfer. We can get from comparative analysis that one-platform transfer is the most effective method through comparative analysis. This paper proposes the handling methods of transfer stations combined with complex network theory, using the betweenness centrality identify the Hub nodes of the network. We replace ordinary transfer station with one-platform transfer station according to node sort, and analyze the change of network parameters in order to evaluate the influence of one-platform transfer on network efficiency.Taking in the urban rail transit network of Beijing as an example, we analyze the changes of network parameters along with the increase of one-platform transfer station with network theory, Matlab software. The results show that the network efficiency is in direct proportion to the number of one-platform transfer station. The network efficiency increases by5%and the shortest path decreases by0.37when the number of replaced one-platform transfer is ten. In addition, the one-platform transfer can enhance the network’s resistance against random and deliberate attackThe example of Beijing shows that the positive of the one-platform transfer stations, this will provide theoretical foundation for the choice of the style of transfer stations.
