Abstract
In this study, risk communication using the continual workshops on flood risk management was implemented at Kosen town-community in Kumamoto City. Consequently, a practical evacuation drill for virtual flood scenario was produced there. The data of observing evacuation behavior were obtained. An evacuation simulator using multi-agent model was also developed. Then, tests of the simulator were proposed through making a comparison between the spatial and temporal accuracy of the simulator and the data of the drill. The spatial accuracy was found to be dependent on the inhabitants’ recognition rate from their own house to the evacuation route.
