Container terminals are developed in many local ports of Japan these days. They are supposed to be used for container traffics from/to Eastern Asia such as Korea, Hong Kong, China, etc. Such developments may be excess investments in the infrastructure although they provide a wide variety of import/export channels. The hub function of major ports in Japan has been lost in competitive circumstances with ports in neighboring countries. In order to achieve the scale of economies in favor of large container vessels, carriers must choose fewer ports to be called without distributing container cargoes over board channels. Thus, feeder service should be provided with lower costs and high frequency, in order to facilitate gathering cargos to fewer hub ports. In this paper, we analyze container traffics from/to Japan with consideration of domestic feeder transports connecting major ports and local ports, and propose a model of international container traffic, which is a competitive method among shippers with user equilibrium assignment. By case studies, we verified the effect of feeder service with lower costs and high frequency.
