Compact Development of Strategic Regions in Urban Spaces: A Comparison Study of Rail Transit Central Stations in China

ABSTRACT As the principal goals of the current intensive development are the systematisation of resources and the intensification of the built environment, compact cities have become a basic urban planning theory and strategy in the country. As a result, TOD is now the primary method for implementing regional intensification, which is consistent with compact city development. There is, however, disorderly growth in density and a lack of clarity regarding the functional combination of current strategic regions of central stations in Chengdu. Consequently, this study discusses how to quantify and propose reasonable standards for intensive development within the TOD station space, where density continues to increase. Considering Shanghai is the leading city in China for TOD development; this study will focus on Shanghai's TOD strategic region. This will allow us to gain a better understanding of the urban compactness index for Chengdu's central stations. Based on the principle of normal distribution, the indicator target thresholds for different types of regions in Chengdu Central Station were analysed, providing quantitative support for the development of the strategic region of the central station.
