Abstract
The aging society in Japan is proceeded so rapidly as the other countries has never experienced. We built many large-scaled new town in the fringe areas of the cities in 1960's and 1970's. Now most of the residents who removed in those years become an advanced age. Such housing complexes have a structural aging problem. In terms of the urban facilities planning we can observe an Unbalance between the facility allocation and the potential of use. Therefore it is important to improve the accessibility for the facility and to consider an appropriate facility allocation. It is also necessary to evaluate the level of improvement in the use of facility more spatially and minutely.
In this study we apply Geographic Information System (GIS) to the evaluation of accessibility and the degree of improvement in the use of medical facilities by using the construction of traffic network and the removal of the facilities. It was found that the combination measure with the removal of medical facilities and the increase of bus networks produced an effect on the rectification of regional disparity of accessibility. Through this discussion we also revealed the spatial population distribution and the accessibility distribution in each generation.
