Abstract
Reducing CO2 emissions is a very important mission in green transportation. In Japan about 20% of total CO2 emissions are from transportation department. Modal shift from truck to railway or ship transportation is a good alternative because it may bring a lower environmental impact. In this paper, a geographical simulation model is constructed in where the advantageous areas of railway can be shown, comparing with truck transportation when the departure point is given. Three evaluating factors of transportation cost, delivery lead time and CO2 emissions are combined into the geographical framework to clarify the advantageous areas totally by the modal shift. Simulation experiments are designed and executed based on the real data of Japanese companies, to show the performance and utility of the model.
