Functional orientation and spatial siting of subway stations based on land potential and mixed land use

Abundant evidence has shown that the integration between urban rail transit system and urban land use planning is of key importance for cities' sustainable development. For planners and city managers, it is essential to scientifically understand the influencing mechanisms between the functional orientations as well as physical locations of the transit stations and the land use patterns alongside. We established a measurement system for the potential of land parcels. Further, we evaluated the land potential alongside a specific subway line, and conducted interaction analysis for between passenger volumes and station-surrounding land mixing degrees. In the end, we sited the subway stations according to the distance constrains and compared the planning outputs from our methods and the plans proposed by the government section. The result is they basically matched with each other, except for some minor differences that could be explained rationally, and the functional orientations of these stations are similar.@2022 THE AUTHORS.
