Investigation of an Agent-Based Modeling on Crowd Evacuation and Its Application to Real Buildings

An agent-based modeling and the simulator for evacuation from multistory buildings at the time of outbreak of an earthquake and the fire are presented. The basic theory is that individual agents move in each floor and stair, unless it is filled to capacity per unit area. The simulator can reflect the situation when some destruction occurred in a passage and the stairs in the middle of refuge, because the capacity can be changed dynamically every place. Each agent moves in principle based on local information around oneself. However, as for the cases that the inside of stairs has been clogged up, wide area information equivalent to the broadcast in the hall is conveyed to agents after pre-determined time. Comparative study with the real measurement and simulation was carried out about the refuge time of the fire drill that was performed in a university building of 12 stories.
