Recently, interest in safety has been increasing in every area, especially in the field of transportation. The accurate evaluation of the stability of road facilities is needed to improve the level of safety in the field of transportation and the application of new technologies is required to reduce the number of natural disasters. In this study, the wind data were compared and analyzed according to the type of measurement, and an evaluation of the stability of road signs using the wind data was conducted. In addition, a stability plan to secure road signs was elaborated and its effect on the wind load was analyzed. It was found that the wind data measured by a mobile atmospheric observing system (MAOS) was 2.43 times bigger than that measured by the Korea meteorological administration (KMA) and road weather information system (RWIS). In terms of their stability, the road signs were susceptible to failure caused by gusty winds and it was found necessary to ensure their stability. In the future, it will be possible to evaluate the stability of road facilities using road line weather data and the application of wind load reduction technologies is expected to improve road safety.

In this study, the road construction field of high impact in the construction industry were selected, and the analysis of the detailed technology level was carried out. and we derived the main fields for future overseas. As results, the technology level of road facilities in korea was high about road operations and management sector, while it was relatively row about road pavements. And this study, we analyzed the economic, social and technological priority, and derived main fields to have the high investment efficiency. A derived items are found to be "maintenance-free Modular Road Pavements" and "Cities temperature reduction-type road".

Recently, road subsidence has been increasing in urban areas, threatening the safety of citizens. In the lower part of the road, various road facilities such as water supply and drainage pipelines and telecommunication facilities are buried, and the deterioration of the facilities causes the road subsidence. In particular, in the case of old sewer pipes which are attracting attention as a main cause of road subsidence, the management of sewer pipe replacement, repair and reinforcement is being performed depending on the burial year. Therefore, in this study, we tried to suggest a reliable road subsidence risk assessment method considering various sewer specifications and surrounding environment information and CCTV exploration result and GPR exploration result.

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.

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.

Recently, the development of the information-communications industry has created a new paradigm of the ubiquitous and the smart environments. An USN is a typical technology for constructing a ubiquitous environments. But the USN technologies applied in practice have a lot of problems and to solve these problems that this study was to build a test bed. For the creation of the needs of USN technology, we suggest a method and service of monitoring of road hazards combining the USN and the Geographic Information System(GIS). We conduct making the USN equipment relevant provisions surveys, making installation guidelines, construction system and real-time testing. This study is capable of the management of public facilities, real-time monitoring of accident and the environment data and is expected to be expanded to a 3D facility management combineded with BIM in the future.
