Although it is important to retain the flood water within the river channels by using dikes and reservoirs, these facilities alone cannot cope with excessive floods. In Japan, appropriate combination of facility-based and non-facility-based countermeasures is getting more important. To determine nonfacility-based countermeasures, we need to simulate flood hazardous situation. However, simulation models which include only evacuating on foot are not enough because our society and our lifestyles are based on using cars. In this study, a evacuation simulation models which express the signal control is developed. This model leads to develop a model which includes using cars. The performances of this model have been tested in the several simulation results in actual flood-plain areas in Japan.

Although it is important to retain the flood water within the river channels by using dikes and reservoirs, these facilities alone cannot cope with excessive floods. In Japan, appropriate combination of facility-based and non-facility-based countermeasures is getting more important. To determine nonfacility-based countermeasures, we need to simulate flood hazardous situation. However, simulation models which include only evacuating on foot are not enough because our society and our lifestyles are based on using cars.In this study, we developed a model to express the behavior of the car in three simple modes. This enables us to simulate the car's actions in a realistic manner at least. The performances of this model have been tested in the several simulation results in actual flood-plain areas in Japan.
