고속도로란 지역과 지역을 연결한 간선도로로 장거리 통행을 주 교통으로 하여 지정된 진출입외에는 완전히 출입을 제한한 자동차 전용도로이다. 영문으로는 freeway, Expressway, Motorway등으로 표기한다. 고속도로 건설은 정부투자 기관인 한국도로공사(Korea Highway Corporation)에서 공사를 발주하여 주로 대형건설업체들이 시공하고 있으며, 이에 대한 시공관리는 대개 도로공사 건설사업소 단위로 시행하고 있다. 고속도로 건설공사의 개략적 구성을 보면 토공, 구조물공, 배수공, 터널공, 부대공 등으로 형성되고 있으며, 시공형태는 대형화, 기계화 되어감에 따라 재해의 유형도 변화가 일고 있다.(중략)

포장도로는 신설된 후 계속적인 차량의 통행과 기후 조건의 변화등으로 시 간이 경과함에 따라서 그 상태가 저하된다. 따라서 포장도로는 일정기간이 지난 후에는 쾌적한 차량의 통행을 보장하기 위하여 유지보수를 실시하여야 한다. 이러한 유지보수를 효율적이고 과학적으로 수행하는 것은 대단히 중요 하다. 미국과 같은 선진국의 경우 도로 신설의 투자비 보다 유지보수에 사용 되는 예산이 더 많아지고 있는데 효율적인 유지관리 시스템의 개발로 투자 비를 적정화하고자 하는 노력이 크게 증가되고 있다. 도로 포장 구조체가 도 로 이용자에게 어느 정도의 안전성, 쾌적성 및 신속성을 제공하고 있는가를 평가하는 것은 포장관리의 중요한 고려사항이며 그 결과는 포장의 공용성 개념으로 표현된다. 포장상태 조사시 포함되는 항목들은 포장유지관리 시스 템을 운용하는 기관마다 약간씩 차이는 있으나 대체로 노면조도, 노면장애, 구조적 능력, 미끄럼저항등이다. 이중 진동계측장비가 많이 사용되는 항목은 노면조도와 구조적 능력평가 부분으로서 이 두 항목에 포함되는 진동 계측 장비와 그 이용방법에 관해서 논하고자 한다.

기존에 운영되고 있는 공공시설관리 시스템들을 효율적으로 관리하기 위해서는 유지관리 모형이 표준화되어 범정부EA 지원시스템에 목표아키텍처로 등록되고 더 나아가서는 범정부 표준시스템으로 만들어 필요한 기관에 보급할 필요가 있다. 이 연구에서는 도로, 터널, 철도 등 인프라 시설관리 정보시스템을 구축하는데 필수적인 성과참조모델을 범정부EA 관점에서 제시하였다. 제시한 참조모델을 기준으로한 자산관리모형 아키텍처 모습이 GEAP에 등록 관리 된다면 이것을 바탕으로 타 기관에서 향후 정보시스템을 구축할 때 사전에 파악하고 활용하도록 제안 할 수 있을 것이다.

In recent years, the service life of major SOC facilities in south korea has exceeded 30 years, and rapid aging is expected within the next 10 years. This has led to a growing recognition of the need for proactive maintenance of these facilities. Consequently, there have been numerous research efforts to introduce smart inspection technologies into maintenance. However, the current system relies primarily on manpower for safety inspections and diagnostics, and on-site surveys rely on visual inspections. Manpower inspections can be time-consuming, and subjective errors may occur during result analysis. In the case of tunnels, there are disadvantages, such as the loss of social overhead capital due to partial closures during inspections. Therefore, institutionalizing smart safety inspections is essential, considering specific measures like using advanced equipment and updating qualifications for experts. Furthermore, it is necessary to verify and validate safety inspection results using advanced equipment before instituting changes. This could be achieved through national-level official research programs and the operation of verification and validation institutions. If smart inspection technology is introduced into maintenance, routine inspections of SOC facilities, such as tunnels, will become feasible. As a result, maintenance technology capable of early detection and proactive response to safety incidents caused by changes in facility conditions is anticipated.

As it is being changed to information society with high economic development, every kind of work is being specialized and diversified in the aspects of quantity and quality. Therefore, Geo-Spatial Information System (GSIS) is getting more important because it can integrate the attribute, the image and the written data of objects including the site one. The purpose of GSIS is to integrate such geo-spatial data as the situation of public facilities, land uses and its sketch and statistics which are scattered in every administration department. Additionally, GSIS can make users get the goo-spatial information easily through computer, and can also do it worthier. An integrated management system of transportation data is needed to improve the efficiency of road-related operations. This can be accomplished by analysing various operation about road management and the utilization of base maps. Thus, in this study, effective road facility information management system based on GSIS database was developed for the management of various types of drawings and data using in various tasks.

In Korea, National spatial data infrastructure has implemented in order to integrated manage and share the national spatial information producted by public agencies and local governments. The necessities of systematic quality management are raised, because information, which is generated by different agencies, is integrative managed by national level. In this paper, the establishment of BPR(Business Process Reengineering) for national spatial data infrastructure quality management system. Quality management business is defined as quality management object definition, quality measuring, evaluation and analysis, and quality enhancement process. Next, activities for each process are designed. For the quality management business, business rule(BR) is required for determining error. We derive the BR for six objects(legal-dong, railway boundary, railway centerline, road boundary, road centerline, building) among the basic spatial information. Other information's BR can be generated by using the derivation method described in this paper. Based on the BPR of this paper and derived BR, national spatial data infrastructure quality management system can be implemented in the future.

Road surface damage detection is essential for a comfortable driving environment and the prevention of safety accidents. Road management institutes are using automated technology-based inspection equipment and systems. As one of these automation technologies, a sensor to detect road surface damage plays an important role. For this purpose, several studies on sensors using deep learning have been conducted in recent years. Road images and label images are needed to develop such deep learning algorithms. On the other hand, considerable time and labor will be needed to secure label images. In this paper, the adversarial learning method, one of the semi-supervised learning techniques, was proposed to solve this problem. For its implementation, a lightweight deep neural network model was trained using 5,327 road images and 1,327 label images. After experimenting with 400 road images, a model with a mean intersection over a union of 80.54% and an F1 score of 77.85% was developed. Through this, a technology that can improve recognition performance by adding only road images was developed to learning without label images and is expected to be used as a technology for road surface management in the future.

Road construction projects have a long duration so cost overruns and schedule delays are occurred. However, performance assessment system that can manage and prepare for this in advance is insufficient. In addition, road construction are affected by many factors during under construction. Therefore it is necessary to conduct performance assessment considering the characteristics of roads and prepare for similar projects in the future. The purpose of this study is to provide a framework to evaluate construction phase performance and present a performance management plan using road construction information. Also, This study conducted time adjustment between the start and the finish of the project and developed performance metrics based on absolute and relative indicator. This study analyzed the cost, schedule, and changes of the road project construction process, showing the possibility of advancement of performance assessment and how to use it when planning new road construction projects.
