Abstract

Recently, in order to obtain the planning information such as a compact city policy, the use of micro-geo data has been applied effectively. In this study, we develop a method to estimate the hourly population inflow during downscaling the spatial analysis resolution by using the RBF Network with respect to the two mobile data of the mobile spatial statistics and the urban planning basic survey. In this study, a model is formulated that estimates the population inflow of each mesh from the total floor space by building application counted on the regional mesh level 3 (1km square grid) scale for estimating the population on the regional mesh level 4 (500m square grid) scale. According to the spatial visualization of the obtained population distribution by this method, it can grasp the distribution of population easily in which it is better than estimating with 3rd scaling.
