摘要:Just after inevitable Nankai Trough earthquake in Japan huge amount of emergency relief supplies must be transported rapidly. Truck transportation is supposed to be the main means but there is a non-negligible possibility that its capacity becomes heavily insufficient because of road network damage and shortage of available number of truck resources and so on. In this paper we propose major-scale ferry/roro fleet transportation in Japan Sea for "push-type" transportation period as a redundant means. We discuss the necessity of the proposed transportation system and show its qualitative merits and quantitative performance by using variety of numerical backbone transportation simulations between cargo origin and logistics hub of the destination area.
