Evaluating and Enhancing Transit-Oriented Development at Xi'an Rail Transit Station
This paper addresses the problem of mismatch with the surrounding urban renewal when applying the TOD station-city integrated development model to domestic rail transit stations.Based on the classic node-place(NP)model and the introduced node-place-ridership(NPR)model with passenger flow,this study takes Xi'an Metro Line 3 as an example.Relying on spatio-temporal big data,passenger flow data within 24 hours for six consecutive months are selected to calculate the basic indicators of 26 stations,which are classified into six categories:place-ahead and low ridership,deficient and low ridership,matching and mid-low ridership,node-ahead and mid-high ridership,node-ahead and mid-low ridership,and saturated node-ahead and high ridership.This results indicate that Xi'an Metro Line 3 has the characteristics of a relatively higher node value and a lower place value.Given the identification of the same characteristics across the six station types,we propose precise matching strategies for place-ahead,coordinated,and ahead type stations.Specifically,place-ahead stations should prioritize connection with other transportation modes and pedestrian accessibility,coordinated stations should optimize supporting facilities and explore the potential of place features on this basis,and ahead stations should integrate resources to form railway microcenters.These three process-oriented transformation measures can be applied to other regions and contribute to improved station function and service.
