- Abstract
- It is very important to assess overall infrastructure performance in order to establish a national plan for sustainable development and to make a long-term financial budget. The purpose of this paper is to investigate the overall performance of infrastructure facilities and propose a method to determine investment priorities for performance upgrades. In order to evaluate infrastructure performance, we categorized infrastructure into nine facility groups: roadways, railways, subways, ports, dams, buildings, levees, water supply and sewerage, and retaining walls and then conducted an expert questionnaire survey about facility performance using a Likert scale 1 to 5: highly dissatisfied, dissatisfied, neutral, satisfied, and highly satisfied. As a result, it was found that the current overall infrastructure performance in Korea had increased by 3.5% compared to year 1994. The facility performance rankings were in the order of dams, roadways, levees, ports, buildings, railways, retaining walls, water supply and sewerage, and subways, which means that investment should be prioritized to subways as well as water supply and sewerage to improve their performance. We also developed a Matrix of Performance Satisfaction that demonstrates trends of performance satisfaction. It is expected that facility performance can be evaluated more thoroughly using the proposed method.
