Outline of Final Research Achievements

This paper aims to establish an integrated model of evacuation preparedness and evacuation behavior on the basis of their heterogenetic decision-making processes, and obtain policy implications to promote evacuation behaviors. The main research achievements are summarized as deepening an understanding of ①the effects of time when disastrous threats are approaching, ②the causal relationship between evacuation preparedness and evacuation behavior, ③the causal relationship between disaster-related information acquisition and evacuation behavior, and ④the relationship between acquisition status of disaster-related information and evacuation decision-making processes.

Academic Significance and Societal Importance of the Research Achievements

本研究では，災害の脅威が迫る時間帯によって，住民の避難行動が異なることを示した．また，災害関連情報の取得状況によって避難行動に至るまでの住民の意思決定過程が異なることを明らかにした．これらは既存研究にない知見であり，学術的意義のある分析結果である．また，この結果は災害の脅威が迫る時間帯によって，災害関連情報の発信方法を変更する必要性があることを示唆している．詳細はさらなる検討を必要とするが，その根拠となる分析結果を示した点は社会的にも意義のあるものである．
