JAUE2017-110: A Technology Developed to Select the Most Optimal Evacuation Routes for Local Residents in the Chemical Accident Area

Abstract

Since the hydrofluoric acid gas leakage accident in ‘Hube Global Chemical Plant(2012)’, the incidence rate of 
chemical accidents has consistently increased. While only nine chemical accidents were reported in 2012, the 
number reached 105 cases in 2014, instigating fear and anxiety among the Korean people. Also During major 
chemical leakage accidents, aged chemical plant facilities and carelessness of workers contributed to increased 
damage by the accidents. Depending on how aged national industrial complexes are, the risk of chemical leakage 
accidents may be expected to increase. Accordingly, it is becoming increasingly important to establish an 
evacuation plan that can be utilized in times of chemical leakage accidents. In this paper, a virtual chemical 
accident scenario is selected using damage assessment and resident notification system of risk management plan 
used in Korea. And then, using GIS and Urban-scale evacuation simulations have been developed to derive 
optimal evacuation route
