AUTOMOBILE TSUNAMI EVACUATION MODEL TO MINIMIZE THE RISK OF BEING CAUGHT BY TSUNAMI

Abstract

Evacuation using a car got allowed if it is needed after the 2011 Great East Japan Earthquake. Each local government has to renew its evacuation plan with consideration of car usage. This study proposes an automobile tsunami evacuation model to minimize the risk of being caught by tsunami. This linear programming model explicitly describes locations of automobiles at each time in the framework of cell-based traffic model. It will estimate the minimum risk value realized by the present infrastructure such as roads and shelters. Owing to the simple LP (Linear Programming) formulation, the proposed model has enough applicability for realistic municipal level network.
