Global warming has caused a number of serious disasters in Japan and abroad. Meanwhile, disaster forecast information is becoming more sophisticated every year, and the means of communication is evolving with the spread of smartphones. Despite the fact that disaster information is readily available, the spread of damage has not been contained. Minimization of damage could be achieved through evacuation actions by those who do not evacuate. The purpose of this study is to derive the best information transmission method for guiding evacuation in river floods. What information communication methods can be considered to achieve effective evacuation? With the goal of changing the behavior of residents, including those who cannot obtain disaster information, those who obtain disaster information but do not take evacuation action, and those who do take evacuation action, we will conduct research on disincentive to evacuation action and intervention methods.
