This study developed a microscopic simulation evacuation model considering car-following behavior in flood situation using software AIMSUN. We formulated the relationship between car-following free velocity and the depth of water by information with respect to the accurate representation of vehicles dynamics properties under flood. Moreover, a flood prediction model combining traffic analysis is conducted to catch up with the momentarily changed network because of the disaster. We also compare the effectives of different departure models of human behavior. They are exponential and simultaneous activities. The results indicate that the flood significantly affects the evacuation and that strategies promoting smooth evacuation activity are very important.
