自動車による避難行動と道路上の信号制御を考慮した水害避難行動モデル

Abstract

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 non-facility-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 and the behaviors of cars is developed. The performances of this model have been tested in the several simulation results in actual flood-plain areas in Japan.
