河川氾濫水害に際した住民の避難意思決定要因の構造分析

抄録

Although residents’ early mass evacuating would be the most important issue to reduce human casualties caused by river flood, people tend not to act under flood hazards. Focusing on "burden and anxiety while evacuating" among inhibitory factors from the action, we conducted a questionnaire survey on residents in Joso City, Ibaraki Prefecture in order to evaluate the influence of the factors quantitatively. Based on the obtained data, we constructed structural equation models on residents’ decision making to evacuate by using simultaneous analysis of four districts in the city. Through interpretation and consideration about these models, we suggested effective measures to promote evacuation for each district.
