Description

This paper investigates locational changes of public facilities such as stores, nursing home, etc. between 1970 and 1999, north of Chuo Line between Kichijoji station and Mitaka station of Musashino City. Twenty-eight types of facilities located at various places totaling 98 in 1970, 1980, 1990, and 1999 were investigated using telephone directories and residential maps. We estimate the density distribution function for each facility using the kernel estimation method and compute distances between distributions as a proximity measure of locational pattern. Six clusters are obtained by the hierarchical cluster analysis using distance matrix. Ninety-eight locational patterns are plotted on two-dimensional space obtained by the multidimensional scaling and periodical changes of facility location pattern are traced.
