The 20th and 21st joint COTA International Conference of Transportation Professionals (CICTP 2020-21)

Urban rail transit is the backbone of urban public transportation and undertakes most of the passenger flow and residents’ travel. The attractiveness of rail transit is directly affected by whether the layout of rail transit stations is reasonable and whether the station accessibility is good. However, the existing classic accessibility evaluation methods do not fully consider the comprehensive impact of the station and external space on accessibility. This paper comprehensively considers the influence of passenger flow, land use, transportation network, and connection methods on accessibility, and establishes a comprehensive evaluation model for accessibility based on indicators including the attractiveness, population, road density, and public transit facilities. The paper takes several important stations of Metro Line 1 in Kunming, China as an example, and conducts a comprehensive evaluation of the accessibility of typical metro stations. The evaluation results show that the accessibility of the line stations gradually decreases from the city center to the suburbs, and some stations are prominent. The correlation between accessibility and indicators was verified, and conclusions about urban planning and transportation development were drawn, which provided an important reference for future station planning and construction.
