Measuring Metro Accessibility: An Exploratory Study of Wuhan Based on Multi-Source Urban Data

Metro accessibility has attracted interest in sustainable transport analyses. Hence, the accuracy of metro-accessibility measures have become increasingly vital. Various spatiotemporal factors, including by-metro accessibility, land-use and to-metro affect metro accessibility; however, measuring while considering all these components simultaneously is challenging. By integrating factors into a unified analysis framework, this study aims to strengthen method for assessment. Specifically, we proposed “By metro–Land use–To metro” model conduct index develop an accessibility-based station typology. The results show that Wuhan system presented “high-medium-low” spatial disparity from urban center periphery. Meanwhile, variety characteristics typologies will equip planners policymakers with useful tool better organising accessibility.
