Abstract
Modal Shift is very important policy to achieve the Kyoto protocol's targets in Japan. Therefore, a lot of researchers have shown the thesis about modal shift, though they have analyzed the ferry and container ship. However, the ferry and container ship are fewer than the general coastal ship called non-unit-load ship for modal shift. In this paper, the authors studied on the mode/route choice model of the non-unit-load ship for modal shift. Firstly, the authors will show a mode/route choice model with logit model. Secondly, we will investigate the factor of mode/route choice. Finally, we will describe the effective policy for the modal shift and the reduction of CO2 emission via modal shift from roadway to marine transportation.
