防犯カメラ映像に基づく大規模集客施設での地震時避難行動シミュレーション

抄録

A shopping mall where many people gather is at high risk when an earthquake occurs. Analysis of human actions during an earthquake is one of the important issues in considering evacuation planning. In this study, evacuation simulation model during an earthquake is constructed based on video movies of security cameras in shopping malls during the 2011 Great East Japan Earthquake. The simulation for the weekday case is compared with the video movie, showing the validity of the simulation model. In the simulation for the weekend case in which the number of evacuee is twice, the crowd become very dense at the exit during the strong shake, suggesting possibility of accidents. The additional simulation considering a countermeasure shows that opening of side exit doors by employees can decrease the density of crowd with evacuate guidance.
