In Japan, vehicular transportation by semi-trailers and similar means accounts for more than 95% of total domestic transportation of international maritime containers. Restrictions are being eased for heavy containers with gross weights exceeding the general limit values specified in the Road Structure Ordinances and high-cube containers with a height of 9'6". However, Japan still faces many traffic-related problems originating in the poor road environment of the country. To realize efficient transportation of international maritime cargos, it is necessary to implement effectively infrastructure construction projects which consider the linkage between ports and roads. Therefore, it is necessary to clarify actual conditions in the domestic flow of international maritime cargos and port selection behavior and construct a transportation route/shipping (or landing) port selection model for international maritime cargos which also considers road bottlenecks, such as narrow roads, outdated bridge and tunnel specifications, tight curves, etc. impassible to large vehicles. Including the models developed previously by the authors, none of the shipping/landing port selection models or transportation route selection models developed thus far, or analyses of the current condition of hinterland transportation and road traffic features in coastal areas has considered bottleneck problems affecting large vehicles such as semi-trailers.
