Factors Affecting Flood Evacuation Decision and Its Implication to Transportation Planning

Abstract

Evacuation decision during flood disasters indicates the choice of households to evacuate or stay from area at risk. This may be viewed as simple decision but involves complex behavioral and other external factors. Evacuation decision serves as key input to transportation planning in the event of flood, hence, careful consideration of the factors that determine this decision should be done. Such factors include broadly the characteristics of households and their capacity as well as risk-related factors. This review identifies the factors by bringing together findings from viewpoint of evacuation managers and social scientists as well as transportation planners. Further research is needed to identify the interrelationships of these factors for consideration in evacuation transportation planning and modeling.
