The evaluation of allocation of evacuation facilities and soft measures for the evacuation of Gangnam ward, Seoul city, assuming inland water flooding

The purpose of this paper is to evaluate allocation of evacuation facilities and soft measures to minimize the damage from inland water flooding in Gangnam ward of Seoul city, using evacuation simulation. Simulation was constructed by Multi-Agent-System. The soft measures are measure of disaster weaks, improvement of evacuation start time, and addition of a temporary evacuation facility and divided into 13 combinations. The soft measures were evaluated with time variation of evacuation rate. As a result of simulation, we understood that improvement of evacuation start time, and addition of the temporary evacuation facility were effective.
