With the systematic comprehensive plan for the 7×9 expressway networks, the condensed investments in the construction of the national expressways has been one major role on the economic growth in Korea. The length of the expressway in 1980 was approximately 2,200km and the length has almost quadrupled in last 30 years. As a result, over 90 percent of the people are accessible to expressways within 30 minutes, which provides higher level of mobility.
On the contrary, the strategic networks of the national roads were not prepared and it has shown the limits to the rational investments. Also, the balanced regional growth oriented diversified investments have contributed to the quantitative growth of the road length; however, it results in the limited considerations of the users’ needs such as on-time performance in road mobility.
The study purposes on setting up the strategic road networks that functionally assists the 7×9 expressway networks and appropriately corresponds to demander’s needs. Moreover, it suggests the operational purposes and management plans for the strategic road networks(SRNs). It analyses the Daegu and Gyeongbul region as a case study.
Based on the KTDB GIS road network files and travel and traffic related big data, the SRNs correspondent to demander’s needs are setup. It considers weekday and weekend passenger traffic volume, freight traffics, and connectivity to major cities, industrial complexes, and tourist resorts.
The SRNs comprises 977km out of 9,458km of the total road length in Daegu and Gyeongbul region. It is made up of the national roads, nation-funded provincial roads, and municipal major arterials. It accounts for only 10% of all roads but carries 35% of all traffics.
The analysis results show that more focused and strategic investments on SRNs improves regional economy and better satisfies demander’s needs. The regulations and policies needs to be amended in order to activate the SRNs investments under the National Government control. The national government and municipalities’ efforts will be needed.
