GIS ANALYSIS OF QUANTITY OF PUBLIC FACILITIES AND EFFECT ON WIDE-AREA PUBLIC FACILITY MANAGEMENT

Some of local governments in Japan are starting to collaborate with their neighbor governments to achieve wide-area public facility management. Although quantitative analysis in terms of effect of the collaboration would give useful information for the future planning of public facility management, no analysis has been conducted at present. In order to fill this research gap, this study focused on this kind of partnership, and aimed to clarify the improvement effects of facilities’ accessibility by quantitative assessment. The detailed process is as follows: 1) to assume two cases, one is non-collaboration case, the other is collaboration case; 2) to measure the road distance between citizens and public facilities by using GIS network analysis program in each cases, in each types of facilities; 3) to calculate the difference of distance between two cases. The results showed that the effects of wide-regional collaboration vary according to the facility types; there is still room for improvement in the border-line areas’ accessibility. Some citizens’ accessibility are improved approximately 10km. Although only a few percentages citizens’ accessibility can be improved, the absolute number shouldn’t be ignored.
