Development of Evacuation Support System in the Areas Affected by Multi-Hazards

Abstract eng:
Our studies are intended to assist the municipality and people in disaster areas affected by multi-hazards. We examined transit plan for evacuate residents to safer areas. We covered confirmation of the safety of people in evacuation center. We will establish a system using the spatial temporal GIS "DiMSIS". The system consists of three processes; (1) traffic weighting, (2) route search and (3) transportation planning. Process (1) adopts highly versatile processing capable of network identification and two kinds of weighting in distribution region, etc. In process (2), the shortest route is searched using Dijkstra algorithm, taking account of traffic weighting. This process also has neighbor search capability around the destination such as evacuation center, in case of discrepancy between the location of evacuation center and network. Process (3) develops a transportation plan, by combining the optimum solutions at every time points and using greedy algorithm to obtain an approximately optimum solution as a whole.
