Abstract
There are many tangible factors such as environmental problem, road traffic jam and labor shortage to restrict the domestic physical distribution. In recent years, the modal shift that means the shift of means of physical distribution from road to rail or ship is more and more strongly needed. In these circumstances, the index that was calculated the base of various conditions is necessary, to grasp the transport characteristic of domestic cargo from a more different point of view.
In this paper, first of all, after domestic cargo is classified with the general cargo and industrial basic cargo, and the volume of domestic general cargo by convencional ship, container ship, roll on/off ship, ferry, rail and track are estimated at each transporting distance zones. Second, the share of transporting mode and the share by ship are calculated at several transporting distance cases, and the characteristic of marine transporting mode in domestic general cargo are grasped.
As the result, value of share of cargo weight and transporting distance ton kilometer by ship is 33% for over 300km transporting distances, 39% for over 500km. And, as the transporting distances are getting longer, the values of share by ship are getting larger.
