Correlation between Underground Space Intensity and Land-Use Transport Interaction

Abstract

Urban planning for vertical space use must consider underground space form and intensity. But little researches and investigations about it have been done. Planners have little knowledge about quantitative mechanism of underground space developing and evolution. Advanced countries developed experienced data of underground space distribution. Modern statistical analysis method provides an efficient tool for this kind of quantitative and empirical research of spatial correlation. This paper selected some of the major characteristic indexes of land-use transport interaction and induces spatial statistical model to analyze the correlation between intensity of underground space use and the indexes of land-use transport interaction in central four districts of Tokyo City. Results show that the intensity of underground space use has positive and stable quantitative correlations with land use function (LT), land price (LP) and floor area ratio (FAR), especially significant in commercial and mixed land-use areas. The influencing factors of land-use transport interaction could be used as external indexes for forecasting the intensity and spatial distribution of underground space in urban central areas.
