Analysis on Relationship between Walking Accessibility of Life Service Facilities and Population Density, and Disaster Risk, in Nationwide Residential Promotion Areas

Abstract

In this study, we focused on walking accessibility to life service facilities in nationwide residential promotion areas and compared the results by municipality, and revealed that Walking accessibility to medical facilities especially are high. Then, we examined the relationship between walking accessibility to life service facilities and population density, and disaster risk per 500m mesh. We showed that the higher the population densities, the higher the walking accessibility to life service facilities. We also made cleared that, for meshes with similar population densities, the higher the walking accessibility to life service facilities, the lower the risk of landslide disaster, but the higher the risk of flood disaster, which was stronger in municipalities with higher population densities in the residential promotion areas.
