経営環境変化を考慮したトラックによる経路選択モデルの構築とフェリーへのモーダルシフトに関する研究

Abstract

Recently, various problems caused by truck transportation, such as traffic congestion, air and noise pollution and lack of truck drivers, have become more serious. In this situation, the shifts from trucks to other transportation modes like ferry boats, which is called the modal-shift, are expected. On the other hand, between Honshu and Awazi island, the Akashi Kaikyo Bridge was opened in 1998. The opening of this bridge has led the change of track transportation routes from by using ferry boats to the Akashi Kaikyo Bridge and the changes in the business environment of truck operators. The purposes of this study are to build the route choice models for trucks that take account of changes in the business environment of truck operators caused by the opening of the Akashi Kaikyo Bridge and to analyze the possibility of modal-shift from the Akashi Kaikyo Bridge routes to ferry boats' routes, by using the models built.
