Land carrier transport the freight from marine terminal to inland destination via roadways. The carriers determine service charges and delivery routes (or port services) at different parts of the multimodel transportaion network through competitions and other interactions among them. Hierarchical interactions occur between ocean carriers and port terminal operators and between port terminal operators and land carriers, respectively. At the upper level interaction, port service conditions affect ocean carrier routings, while port throughputs are influenced by ocean carrier decisions. Ocean carriers departing from a marine terminal choose a destination terminal from among the alternative ones by considering the ocean transportation network as well as port determinants such as the port location and service level.
