Theoretically, transit-oriented development (TOD) can enhance accessibility by providing a relatively high level of transport connections and high-density, mixed-use, cycling- and pedestrian-friendly land use around transit stations. Empirically, there is a noted positive relationship between the transport component of TOD and accessibility, but the evidence is more mixed with respect to components other than transport (e.g., high urban density and diversity, or proximity of land uses to the transport node). In order to examine how the specific components of TOD are related to accessibility and the relative importance of each component to enhance accessibility, the paper develops a methodology to explore the relationship between each TOD component and accessibility, and applies it to Beijing, China. First, the paper assesses the accessibility of metro station areas in Beijing. Second, it studies how TOD components are related to accessibility at the one-hour travel time catchment level. The results highlight that, in the Beijing context, both a station area’s location relative to the city center and the land use pattern (e.g., a relatively lower average residential density; a relatively higher average all-job density; a relatively lower average job density in the sector of retail, accommodation, and catering; a relatively higher average job density in the sector of education, health, and culture; and a relatively lower average degree of functional mixes) around all the stations within the targeted station’s one-hour travel catchment are relatively more important to enhance the area’s accessibility than improving the area’s transit performance. This outcome provides insights for developing area-specific and targeted strategies to enhance the accessibility of a given metro station area in Beijing.
