Development of tsunami evacuation simulation for Banda Aceh City planning

The tsunami evacuation simulation which combines tsunami inundation simulation and people evacuation simulation was confirmed to be one of the effective disaster education tools from the experiences in Japan. This simulation technology has been advanced and applied to the west half of the tsunami risk area of Banda Aceh. And, its utilization methodology for tsunami disaster education and for city planning has been studied under the cooperation with the school teachers and the city office staffs. Linking these two simulations onto a common time-domain, the animation is compiled and the number of casualties is counted from the location of evacuee and the spot depth of tsunami. The study originated the road network data and population data of Banda Aceh using a high resolution satellite image and door-to-door visits. Several simulations were developed under different scenario parameters such as the timing of the start of evacuation, the method of moving (car is available or not), and the destination of the evacuees. The simulation handles more than 10 thousand agent models.
