Abstract

During the last century, the modal split structure of the Korea transportation system has been shifted from a rail-oriented to a road-oriented structure. The shortage of the infrastructure to accommodate the rapidly increasing travel demand has brought socio-economic losses such as severe traffic congestion and high logistic cost, and thereby weakens the competitiveness of the country. In this context, the objective of this study is to provide a conceptual guideline of the transportation policy which enhances the efficiency of the national transportation system in the 21st century. Firstly, this study diagnoses the historical trend of the modal split structure and analyses the deficiencies and causes of the current modal split structure. Secondly, this study examines the cases of the modal split structure of the advanced countries. Lastly, basic principles for building an efficient and environment-friendly modal split structure of the regional transportation system is proposed
One of the important feature in the modal split changing trend of the passenger transportation system is that the dominance of the rail over the road was reversed in the early 1960' s. On the other hand, in the freight transportation system, the dominance of the rail over the road was reversed and the marin mode became dominant over the rail from the early 1980' s. The most critical deficiency of the regional transportation system is that overall the roads are being used too much in transporting not only passenger but also freight, especially for the mid- and long-distance transportation. This weakness has created direct problems including severe traffic congestion, high logistic cost, and external costs including high traffic accident rate, air pollution, and enormous fuel consumption.
The current modal split of the passenger and freight transportation of the advanced countries is road-oriented, which is similar to the one of Korea. This result has come from the fact that for last several decades more budgets have been spent on the road rather than the rail in order to accommodate the increasing road-oriented demand resulting from the increasing car-ownership . Since mid-1980' s, based on the recognition of the socio-environmental issues evoked by the demand-oriented transportation infrastructure supply, the advanced countries have initiated numbers of socio-environmental oriented travel demand management and transportation infrastructure investment strategies. Even if there has been no radical effect yet, a positive effect on the modal split structure is expected for a long term.
From the experience of the advanced countries, it is expected that more budget will be spent on the road than the rail because of the increasing per capita GNP and car-ownership, and thereby the modal split of the road against the rail will be increased. In this context, the shift of the national transportation policy is required to enhance the efficiency of the transportation system before becoming more road-oriented transportation system.
In the near future a number of changes including the introduction of express rail and light rail system, exploration of Intelligent Transportation Systems(ITS), advance of tell-communication system, and emerging environmental and traffic safety issues are expected. Internationally with the increment of the free trade and acceleration of the economic cooperation in the far-east region, Korea is expected to role as center of intermodalism. Additionally in case of unification between South and North Korea an inter-connecting transportation network between two Koreas is required.
By taking into account these aspects, this study proposes following directions in establishing
