Empirical Analysis on Concentration Degree of Inbound and Outbound Passenger Volume of Guangzhou Urban Rail Transit

Abstract

Objective Problems in some urban rail transit lines, such as unreasonable directions, station distribution, and transfer station layouts lead to the phenomenon of some high passenger flow stations and extremely low passenger flow stations in urban rail transit network, bringing challenges to both the investment and operation of urban rail transit. Therefore, it is necessary to carry out relevant researches. Method Based on the inbound and outbound volume data of Guangzhou urban rail transit, the concept of inbound and outbound volume concentration degree is defined, and the spatial distribution characteristics of stations with high inbound and outbound volume concentration degree are analyzed, as well as the relationship between the station and the population size within the station attraction range, and between transfer stations and non-transfer stations. Result & Conclusion In terms of passenger flow concentration, Guangzhou urban rail transit line network presents the characteristic of a large concentration of passenger flow in a few stations. Specifically, the stations ranked in top 10% of inbound and outbound volume reach 30% of the total volume of passenger traffic in the whole network, while the stations ranked in top 20% occupy 50% of the total volume of passenger traffic in the whole network. In addition, these high-traffic stations are mainly concentrated in densely populated areas and urban centers.
