This study aims to collect useful knowledge about vehicle evacuation such as evacuation time distribution and evacuation traveling velocity. The empirical surveys were conducted on three evacuation cases in Mabi, Okayama during the 2018 Japan Floods. The authors analyzed the data from each evacuation travel of each elderly facility and classified evacuation types based on the time relationship between the evacuation preparation and the evacuation travel. The study provides abundant information including the time used for getting in and off per resident under three ways of transportation in evacuation and calculated the traveling velocity of evacuation vehicles.
