ABSTRACT Despite significant efforts to enhance accessibility to transportation facilities and transit-oriented development (TOD), the rapid expansion of cities has hindered improvements in citizens’ access to transportation facilities. This study addresses these challenges by aiming to delineate key factors pertaining to access distance that facilitate successful station area development and to identify areas requiring enhancements in public transport access. To measure accessibility and the factors affecting it, various types of mobility and demographic data, including transit fare card data, residential and workplace population density, and the count of bus stops and metro lines, were used to assess access distance characteristics. Findings indicate that bus stops within 500m of metro stations tend to have more bus stops within a 500m radius and lower residential population within a 100m radius, compared to stations with access distances exceeding 500m. Bus stops in the 500m range outnumber those beyond 500m, and their associated residential and workplace population densities are lower. Considering the number of bus stops as well, stations indicating access distances exceeding 500m are relatively scarce in public transportation, indicating lower public transportation accessibility. Therefore, this study suggests that when developing station areas within urban centres, priority should be given to areas where subway station population density is high but distributed over a wide area and the number of bus stops within the station area is low. These findings on the walkability quality factors and considerations to assess the walkability will be a great reference to the policy decision makers to prioritize TOD areas.
