Abstract

In current, studies on the level of road infrastructure have adopted road rate as a key index. However road rate cannot be captured the high level of comfort and convenience for road user. By doing so, this research identified the limitation of conventional studies on representing the level of the current road infrastructure, and suggested alternative methodologies to tackle them. The ultimate goal of this work provides a comprehensive assessment framework to represent delicately both quantitative and qualitative elements. The subject of this study was road facilities among the SOC projects, and the level of road infrastructure. The first step of the analytic methodology, which is the comparative level in the quantitative elements of the infrastructure supply, is proposed. Here, the comparative criteria is the average of national level, which is set to 100. Based on the national average, the supply level of each region were calculated. The second step of the analytic methodology is mobility analysis among the qualitative elements. The methodology of the road mobility relies on travel demand. Lastly, the index of the road infrastructure was developed with a comprehensive concept including both quantitative and qualitative elements. As a result of the analysis, central urban area shows generally low in the rank of the infrastructure index because of traffic congestion while rural area ranks in high. Such results are not exactly matched with the result of the conventional index regarding road rate, which means it may rank in low although the road rate is highly recognized. In other words, the road infrastructure in Seoul metropolitan area are comparatively high, however, it may not be desirable level in the level of qualitative service because the region suffers from regular congestion section. In conclusion, the result of this research is well representative for the overall condition of the road infrastructure in each region. Furthermore, it could help plan an agenda for the balanced development by comparing the qualitative and quantitative level, and ultimately it would be a desirable reference to tackle unbalanced growth in region.
