Analysis of access and egress mode choice to high-speed railway stations

High-speed railway (HSR) has become a key mode for short- to medium-haul transportation intercity trips in China and has been regarded as a competitor to air transportation. While significant research has explored daily travel mode choices and access/egress modes for other intercity transport hubs, the factors influencing access and egress to HSR stations - particularly those related to the built environment - remain underexamined. This paper analyses access/egress mode choices for intercity travel along the Beijing-Shanghai HSR corridor using 2015 survey data. The findings show that, during the access stage, the number of bus stations at HSR stations reduces car use, while the availability of metro stations and a mix of land uses at the origin lowers taxi preference. In the egress stage, mixed land use at the destination encourages bus use. Interestingly, the number of bus stations at HSR stations is positively associated with taxi use, possibly due to congestion caused by large passenger volumes at bus hubs. These results suggest that optimising access to HSR stations requires not only improved public transport infrastructure but also more efficient management of the transportation system.
