Abstract. In the current scenario, where there is no quantitative criteria for the location, size, etc. of the shelter, an empirical study was conducted on the location distribution of the shelter considering accessibility. In this study, a safety zone that can be immediately evacuated using a pedestrian-level network is set up for each shelter. For the case area, a GIS network analysis service area analysis was used to divide the area to be evacuated to each shelter and to generate a base map in which the shelter that can reach the shelter as soon as possible can easily be identified. It is possible to provide a suitable area and evacuation route using pedestrian networks. In an urgent situation, it should be possible to get to the evacuation shelter at least as soon as possible, to avoid the high risk of flooding. Therefore, the service area that considers the flooding maps to be effective for evacuation.
