모바일매핑시스템은 차량에 CCD카메라, GPS IMU등의 장비를 탑재하고 도로 및 주변지역의 영상을 획득하여 지도제작 및 도로 도로시설물의 유지관리를 위한 시스템이다. 그러나 모바일매핑시스템의 자료는 자료의 양이 방대하여 지도제작 및 시설물 관리에 사용되기 위해서는 일차적인 가공이나 편집이 필요하다. 모바일매핑시스템은 대상물의 위치 및 영상정보를 획득할 수 있는 효율적인 시스템으로 도로 시설물의 유지 관리, 수치지도의 갱신 등 여러 분야에서 활용되고 있다. 이러한 모바일매핑시스템은 CCD 카메라 영상과 차량의 위치 및 자세정보를 제공하게 되고 이는 영상안의 객체에 대한 위치정보를 제공하는데 중요한 역할을 한다. 그러므로 본 연구에서는 모바일매핑시스템을 이용하여 영상내부에 나타난 거리표의 3차원 위치를 결정하고자 한다. 또 도로관리통합시스템의 핵심 키가 되는 거리표의 3차원 정보를 자동으로 추출함으로써 모바일매핑시스템의 방대한 정보를 효율적으로 처리하기 위한 방법을 알아볼 것이다.

It is expected that the maintenance cost of domestic bridges will increase considerably due to the increase of bridge service time. In response to this situation, the government and relevant ministries are focusing on developing ways to efficiently allocate limited budgets and to rationally select maintenance bridge. In this study, to develop a risk - based bridge maintenance priority decision model, 14 common risk factors causing damage to bridges were extracted and AHP analysis was performed to select 5 important factors. Based on the existing literature review and expert consultation, we derive the evaluation criteria and the impact weights of the selected factors, and based on this, I presented risk based bridge maintenance priority model. Using this model in combination with existing maintenance priority methods will lead to more reasonable bridge maintenance priorities.

Mongolia is a developing country with a smaller population living across a large territory where infrastructure is underdeveloped. The country has been actively implementing road construction in recent years. The Mongolian government has increased investments in new road construction, but funding for major maintenance or reconstruction projects declined between 2012 and 2016. On the other hand, road network management has not been implemented owing to insufficient road maintenance and If the road network expands, there is a risk that the cost of overall maintenance will increase significantly in the future. Therefore, in order to cope with these problems, this study reviewed applying Korean road model to Mongolia for systematic management of road infrastructure.

This paper proposed a design of intelligent supervisory control systems for maintenance of highway traffic information equiprrent and processing algorithm of equiprrent fault data. The fault data of highway traffic equipment are transmitted from rerrnte supervisory controller to central supervisory system by real time, the transmitted fault data are anaIyzed the characteristic using evaluation algorithm of fault data in central supervisory system. The evaluation algorithm includes a neural network and fault knowlOOge-base for processing the multi-generated fault data. For validating the evaluation algorithm of intelligent supervisory control systems, the rrethod of analysis used to the five pattern of binary signal by transmitted real time and the opTclting user-interface constructed in central supervisory system.

Operation and Maintenance in road infrastructure is repetitive carbon emissions activities to preserve the road in its originally constructed condition. In the view of road planning and construction, operation, and maintenance of life cycle, operation and maintenance stage quantification of carbon emissions is very important because it is easily accessible activities to reduce carbon emissions in road infrastructure that existing and new road. However, carbon emissions estimation in operation and maintenance stage is yet to do, because data collection is so hard and carbon emissions estimation methodology is very complicated. In this study, a basic unit of carbon emission in the operation and maintenance stage of the road infrastructure was developed in order to get the quantitative determination of carbon that occurring. Carbon emissions of the Expressway and Common state road was calculated by using the basic unit of carbon emission and application plan of basic unit of carbon emission are presented.

미국, 영국, 호주 등의 나라들은 최소의 비용으로 도로시설물의 기능을 유지 또는 개선하기 위한 방안으로 자산관리(asset management) 체계를 기반으로 한 정보시스템을 개발하고 있다. 한국은 아직까지 자산관리정보시스템에 대한 연구가 초보적인 수준에 머물러 있다. 본 연구에는 사용자관점의 서비스 수준(level of service)과 경제성 분석기법 간의 관계를 토대로 도로시설물을 유지관리하기 위한 자산관리정보시스템을 개발하기 위한 방안을 제시하였다.
