Abstract
Effective measures against natural disasters are needed worldwide, and the jurisdiction assignment of evacuation shelters during natural disasters is one such measure. In this paper, we discuss two evacuation cases involving tourist accommodations as temporary shelters. One involves evacuation to the closest shelter, and the other involves using our previously proposed optimization method for assigning jurisdiction for shelters. The impact of tourist accommodations on evacuee overflow for each case was investigated. We also explain that tourist accommodations as temporary shelter reduce the evacuee overflow at shelters by using a numerical example. We argue that its impact is limited by giving an example of a city in Japan where the evacuation and residential areas are widely spaced.
