EVACUATION DECISION MAKING MODEL WITH CONSIDERATION FOR SITUATION AWARENESS AT HEAVY RAIN

Abstract

It suggests the existence of a risk perception paradox that high risk perception does not always lead to personal protective actions. This issue is casting doubt that evacuation behavior at heavy rain is considered to be a result of cautious decision making because the slow response occurs frequently. Then, this study applies naturalistic decision model which regards situation awareness as important to evacuation decision making model at heavy rain. The situation surrounding his/her home at heavy rain varies from hour to hour. To be aware of the situation probably leads to raise awareness for the occurrence of flood. In this study, modeling the process of evacuation decision making at heavy rain, we adopt the situation awareness as explanatory variable. Concretely, anxiety scale model for flood are estimated based on the data of the evacuation behavior in Tatsuda area, Kumamoto city on the Northern Kyushu Torrential Rain July 2012.
