Outline of Final Research Achievements

In this study, evacuation behavior and emotion according to the degree of the risk factor (smoke concentration in this study) were clarified and quantified as anxiety, fear and stress and by a model tunnel experiment. There were 147 subjects (including 132 Japanese and 15 Chinese) in 2021, and 46 subjects (42 international students and 4 Japanese) in 2022. In addition, we clarified the difference by nationality in measurements by international students at the university, and made presentations at 2 domestic conferences and the international conference.

Academic Significance and Societal Importance of the Research Achievements

避難安全性の評価し，政策に反映させるにあたって重要になるのは迅速な避難と躊躇するような遅い避難である．迅速な避難は避難情報伝達速度となり，避難開始時間に影響を与える．一方で，同調性バイアスからパニックを引き起こす原因にもなりえる．躊躇するような遅い避難は，犠牲者となる可能性が高く，犠牲者を減らす観点でも躊躇する人へのアプローチが必須である．情動は避難挙動に影響を与えることを昭kにできれば情動を持った急ぐ人と躊躇する人が全体の歩行速度に与える影響を数値化できる．これは，最適政策提言のための基礎データとなる．
