ABSTRACT
The present study aims to propose the method for the quantitative evaluation
of safety concerning evacuation routes in case of earthquake disasters in urban
areas using ACO (Ant Colony Optimization) algorithm and GIS (Geographic Information
Systems). Regarding the safety evaluation method, firstly, the similarity in safety
was focused on while taking into consideration road blockage probability, and after
classifying roads by means of the hierarchical cluster analysis, the congestion
rates of evacuation routes using ACO simulations were estimated. Based on these
results, the multiple evacuation routes extracted were visualized on digital maps
by means of GIS, and its safety was evaluated. Furthermore, the selection of safe
evacuation routes between evacuation sites, for cases when the possibility of large-scale
evacuation after an earthquake disaster is high, is made possible. As the safety
evaluation method is based on public information, by obtaining the same geographic
information as the present study, it is effective in other areas regardless of whether
the information is of the past and future. Therefore, in addition to spatial reproducibility,
the safety evaluation method also has high temporal reproducibility. Because safety
evaluations are conducted on evacuation routes based on quantified data, highly
safe evacuation routes that are selected have been quantitatively evaluated, and
thus serve as an effective indicator when selecting evacuation routes.
