Shared Bicycle-on-Transit Perspective on Rail Transit Station Accessibility and Ridership

Public transport services are constantly transforming, which calls for innovative approaches to adequately model ridership in this complex environment. The increasing availability of shared connecting means of transportation transforms how passengers make travel choices in public transport systems and has solved the first-last-mile problem. This shared bicycle-on-transit travel pattern expands the catchment area of the stations and increases the coverage of rail transit ridership accordingly. However, there are current research gaps in appropriately defining catchment areas, while selecting built environment factors at station level in consideration of shared bicycle connection. To address this challenge, the expansion effect of shared bicycles on the catchment area of rail transit stations is presented and redefined by removing the overlaps. This study also deliberates the impact of shared bicycles on the range of built environment when conducting a spatial autocorrelation regression model.
