A Review of Recent Studies on Flood Evacuation Planning

Abstract

Flooding is viewed by many as a natural phenomenon, which is necessary for biodiversity. However, with the anthropogenic activities brought about by changes in land-use and climate, floods are observed to be more frequent and severe. In order to avert the negative impacts of flood, preparedness measure such as evacuation is increasingly necessary. This review is conducted to identify recent advances on evacuation research in the view of behavioral science, risk analysis and transportation modeling. The elements of the evacuation process such as decisions, warning, withdrawal, shelter and reentry with relevance to transportation planning constitutes the framework and emphasis of this review. Future uptakes for research include travel behavior that covers decision to evacuate and reentry, and in-depth consideration of the flood hazard, its associated risk and shelter information to evacuation transportation demand modeling.
