Abstract
Taking rail transit station area in Beijing as the research unit and considering both passengers and public service facilities in rail-station area as representative factors for supply and demand respectively, the paper investigates the spatial distribution characteristics and accessibility of public service facilities with Gaussian two-step floating catchment area (Ga2SFCA) method, analyses the influence of built environment based on the Transit Oriented Development (TOD) model. The findings reveal that overall, the distribution of public service facilities along the rail transit stations in Beijing generally shows a favorable trend. However, there are significant variations in accessibility among different types of facilities. High accessibility of social welfare, education, commercial and entertainment facilities can foster similar developments in adjacent regions, whereas medical and health services as well as cultural and sports amenities tend to be more randomly distributed. By examining both supply-demand dynamics for public service facilities alongside their accessibility levels, it becomes possible to effectively evaluate how well a station area functions as a regional center serving surrounding areas while also providing insights for optimizing urban facility configurations.
