Abstract

The analysis of evacuation behaviors from the video captured during the Great East Japan Earthquake revealed that the evacuation behaviors of fleeing and dropping down were affected by the distance from the exits. These behaviors were reproduced through simulations by employing the evacuation decision model, which is a model of herd behaviors during evacuations; this showed that these unique evacuation behaviors could be reproduced by simple herd behaviors. However, the results are questionable owing to the oversimplified settings of the simulations, such as the different number and density of agents and the overlooked physical constraints. We conduct simulations with settings that are more representative of those in the video clip. The unique evacuation behavior is also reproduced with our simulation setting but for limited ranges of parameter values. The analysis of the results reveals that the parameters related to the vicinity of an agent are significant; this lead to the hypothesis that the attention of evacuees is narrowed to 20 degrees with a relatively long range during evacuations.
