Outline of Final Research Achievements

This study examined the guidance methods for the evacuation safety considering the facility plan, which are not supposed in the current evacuation planning. The surveys of the actual conditions and problems of methods for guidance by human and installation of emergency exit sign for evacuation in large scale buildings were conducted, also, the guidance indicated by the emergency exit sign and human were derived empirically based on the experiments. As a result, this study identified that the considerations of both the route conditions and the guidance methods are important to ensure the evacuation safety: the route guidance indicated by the human is necessary as well as that indicated by the sign in large scale buildings, the guidance methods, the evacuee’s route choices are influenced by the conditions of the width of and the congestion in the passage ahead, and the evacuation guidance methods have to be considered on the assumption that the route choice are varied according to them.

建築計画　避難安全

Academic Significance and Societal Importance of the Research Achievements

建築設計時に作成される建築基準法の施設計画と消防法の避難誘導対策は、管轄する行政機関が異なることもあり別個の枠組みの中で計画、実施されており、避難計画については双方を統合した基準や対策がない現状がある。特に、人による誘導と誘導灯を組み合わせた避難誘導について、避難計画では想定されていない。
本研究は、避難計画で想定されていない進行先の空間状況と誘導灯および人的誘導による誘導方法の組み合わせが避難者の経路選択行動に与える影響の把握、およびこれに基づく避難誘導方法の検討を通して、施設計画と避難誘導対策の両者を横断した安全性の高い避難計画を作成するための基礎資料となる知見を提供できた。
