A STUDY ON THE ANALYSIS OF DYNAMIC DECISION-MAKING PROCESS USING VIDEO CONTENT

Abstract

In Japan, unexpectedly heavy rains have caused river flooding, inundation of low-lying areas, and human suffering in many parts of the country. One of the main causes of human suffering is the delay in evacuation of residents. In order to prevent this from happening, it is important to make evacuation information easier to understand so that residents can make decisions and take appropriate evacuation actions. Since May 20, 2021, "evacuation advisories" have been abolished and replaced by "evacuation orders" as the evacuation information issued by local governments. In this study, we use a questionnaire with a video simulating flood damage to reveal the continuous decision-making process of residents, which cannot be collected by a paper survey, such as which disaster prevention action to take and when. Through this questionnaire, we were able to show that the timing of the respondents' evacuation actions, the slowness of their decisions to evacuate, and their lack of disaster prevention awareness.
