Abstract
The purpose of this study is to quantitatively clarify the factors that have transformed underused land in a number of cities. Therefore, we constructed a database of underused land by using housing maps in GIS and analyzed the factors causing the change between 1995 and 2005 for underused areas. We focused on conditions of public transportation and designation of land use districts in central areas of 37 core cities in October, 2005. Furthermore, we also analyzed factors of transformation from underused land to residential land in each lot.
Results show that underused land area has decreased in cities where railway stations have been maintained and underused lands were distributed in close proximity to each other in 1995. Moreover, from an analysis of factors for transformation to residential land, outdoor parking lots have a negative effect on transformation from underused land to residential land.
