Abstract

Trunk road network of Korea was planned for rectangular networks in 7 vertical axes and 9 horizontal axes in 1990 to support balanced regional development of the nation and to cope with travel demand in the future.
The total length of trunk networks will be 6,160km in the future. This plan to meet travel demand and provide equally distributed road facilities to the nation, will make rectangular networks, radial and circular networks for the metropolis as well as circular networks for the whole nation. As of the end of 2000, the trunk road network plan is on the way to make its original 7 and 9 axes. The vertical axes are almost completed but horizontal axes and radial and circular networks for the metropolis are still under construction.
The trunk road networks will provide all road users optimum service by enabling them to access any trunk road within 30 minutes, and support balanced regional development with equally distributed road facilities.
However, it needs large investment until the trunk road networks are established, and it is not easy to ameliorate current traffic congestion problem. In fact, travel demand differs by region, some sections on the road are congested owing to the concentration of travel demand. The travel patterns of current expressway are reflected by the natural resources in the regions and economic activity patterns between the regions. Therefore, some measures are required to soothe malfunctions from the traffic congestion in spite of more road construction, because congested road sections result in inefficient utilization of natural resources.
The purpose of the study is how to set up road networks considering economic efficiency first rather than balanced development. This study consists of 7 chapters and the main contents are as follows.

The chapter 1 is an introduction about the study which explains the backgrounds, purpose, study scope and methods of the study.
The chapter 2 dealt with some theories about the road network system. According to the study, principal roads, which are consisted of expressways and national trunk roads, deal with main traffic flows, resulting in supporting regional economies as well as stimulating balanced regional development. The circular road system is by far the best among road networks in terms of efficiency, but rectangular road networks could bring network effects in the long term.
The chapter 3 dealt with the trunk road network systems of Korea. This chapter explained how the plan for the trunk road network was set up and its chronological processes. Road construction has affected on the location of industrial parks, cities as well as country golf club. The national spatial structure has changed steadily by the road network.
The chapter 4 analysed the expressway of Korea in terms of efficiency. Travel patterns between Interchanges of the expressway were analysed. It was found that major travel patterns on the expressway were short-distance travels within 50km, which were concentrated on the metropolis, and long-distance travels were diminishing. The lengths of congestion sections were doubled from 337km in 1990 to 713.6km in 2000, which shared 33.9% of the full length of the expressway. Especially, internal travel within zones was even over 40% of the section, which made the road condition worse in the Daegu metropolitan areas. Therefore, the expressway would be free when the internal travel are extracted from the sections. This is considered a common phenomena on the current expressway.
