DEVELOPMENT OF AN EVACUATION ROUTE SEARCH SYSTEM CONSIDERING THE DANGER TO LIFE IN DYNAMIC INUNDATION

Abstract

 In recent years, the frequency of torrential rains has increased due to abnormal weather conditions. Torrential rains are extremely difficult to predict and have caused extensive damage in many areas. The objective of this study is to construct a new real-time evacuation route search system that does not involve flooded areas by using a functional form that takes into account the evacuation time and the direction of spread of flooded areas and takes the width between the flooded areas. The number of evacuees was analyzed by comparing the proposed model with the conventional model, which does not take the functional form into account, with the one that does. The results showed that the proposed model has an improvement rate of about 16.5(%) compared to the conventional model, and that it peaks when the value of the coefficient cd is varied.
