International Marine/Air Cargo Modal Split Model Considering Logistics Cost

Abstract

The total volume of international air cargo from/to Japan has been decreasing after 2004. The purposes of this paper are to investigate the characteristics of recent air cargo by “Foreign Trade Statistics” and to develop modal split model between marine and air transport. We clarified that one of the decline’s reasons was based on the decreasing import goods. The developed modal split model calibrates logistics cost which involves time, cost, inventory cost and obsolescence cost. We applied the model to several international OD pairs, and it was verified that the model has sufficient applicability.
