시설·연도·연장에 따른 지자체 민자도로 운영평가자료 특성 분석 = Identifying the Spatiotemporal Characteristics of the Public-Private Partnership Roadway Infrastructure in Operation by Facilities

다국어 초록 (Multilingual Abstract)

The size of public-private partnership (PPP) roads in Korea has been steadily increasing since 1994. The government has been conducting an annual PPP road operation evaluation since 2019 to improve the safety, operation management, and service quality of the increasing PPP road. However, the limitations of the current PPP road operation evaluation system do not reflect the characteristics of facilities and lengths. Accordingly, the government is pushing for a full revision of the standards for the operation evaluation of PPP roads, but the revision mainly focuses on PPP highways, so it does not reflect the characteristics of local PPP roads. This study aims to analyze the current status of local government PPP road operation evaluation by facility, year, and length to derive implications that can contribute to the full revision of local government PPP road operation evaluation standards in the future. Basic statistical analysis was conducted to find out the overall characteristics of the operation evaluation data. In addition, most of the data in this study did not follow normality, so a non-parametric test was used to identify differences between groups, and post-verification was performed after non-parametric analysis. The analysis results are as follows. First, there were many items that lacked discrimination to analyze the characteristics of each facility, year, and length. Second, as a result of inter-group analysis, the characteristic that has the most heterogeneity is the characteristic of each length. Third, items such as the number of road cleaning and the speed of handling civil complaints are items that have heterogeneity in the characteristics of each facility. Fourth, in the case of annual characteristics, there was no item that showed a clear improvement effect. It is judged that the results of this study can be used as basic data to improve the operation evaluation system in the future.
