スタジアム•劇場等における避難性状のマルチエージェントシミュレーションによる予測

摘要

Evacuation flow on the spectator stands of stadia and theaters which consist of complicated evacuation route, such as gangways and gate etc. are examined with the multi-agent evacuation simulator SimTread (MA model). Through those examinations, characteristics of evacuation flow are obtained which should be Merging rate at the radial gangways, lateral gangways, and exit gates change according to the merging condition and with time. 3) The cause of characteristic observed in 1) is analyzed in mathematically. This characteristic is well approximated by multiplier effect of meiging rate and adjusted calculation method is proposed. 4) Theatres of cinema complex which have pitched spectator's seats and have exits only lower area are needed careful consideration for the tendency that evacuees remain high place from the viewpoint of smoke exposure.%スタジアムや劇場等において特有な客席および縦•横通路上における合流を考慮した避難性状予測と煙曝露に対する検討を、マルチエージェント避難モデルSimTread(MAモデル）により再現した。これにより既往の新•建築防災計画指針（指針法）や避難安全検証法（検証法）では得られにくい、火災避難安全上、考慮すべき避難性状が得られた。以下にその結果をまとめる。
