Influence of a New Subway Line’s Opening on Passenger Flow Characteristics of an Urban Rail Transit Network

With new subway lines going into operation, the passenger flow distribution of urban rail transit networks have new characteristics. This paper presents Beijing rail transit as an example. According to different methods of new lines connecting to the existing network, selecting urban trunk line, suburban line and loop line, analyzing the changes of passenger flow characteristics caused by the opening of each kind of new line from several aspects: scale of network traffic, passenger volume of line, passenger flow of transfer station and passenger flow of key section. And summing up general laws of different types of new line’s impact on passenger flow on the basis of empirical analysis. It provides reference for optimizing and coordinating operation organization between the new line and existing lines.
