Analysis of Land Use along Urban Rail Transit Based on POI Data

The land use pattern of the areas along urban rail transit is crucial for the efficiency of transportation system and city sustainable development. This paper analyzes the characteristics of land use along urban rail transit in Shanghai, China from three levels: rail network, lines, and stations by taking advantage of the POI data collected from open source map. The indicators we propose to measure are the land use characteristics including the land use density, degree of concentration, and the entropy of land use structure. The results show that the land use density declines as the distance from rail line increases and the rail transit attracts commercial facilities significantly, keeping away from residential facilities. The result also reveals that the intensity of land use along the rail transit is related to the relative location of the line in the city.
