Multi-agent simulation tool incorporation group evacuation behavior model

Abstract

Evacuation simulation by multi agent model is used to make plans for reducing damages at disaster. In this research, we specially focused on emergent phenomena that aims to provide notices for unexpected evacuation behaviors by expressing embedded individual behavior rules concerning interactions in groups. To construct such simulation tool, we introduced three models as follows; 2-dimensional continuous planes as spacial model, evaluation agents with eyesight and individual behavior rules, and potential models as deciding moving target positions based on mutual behaviors. In the experimental studies, we set two types of agents, that is, agents with notice of evacuation exits and agents without it. Simulation results shows significance of agents with notice of evacuation exits and effects of group sizes as to evacuation behaviors.
