최근 도로시설은 점차 중요성을 띠게되었다. 특히 증대하는 교통사고에 대처하기 위하여 교통안전시설의 정비가 급선무인데 도로조명은 교통안전시설중 가장 중요한 것의 하나여서 도로이용자로 하여금 안전하고 상쾌한 통행을 하게한다. 도로조명은 도로조명의 설치에 의해서 차도및 보도의 도면상황을 밝게하고 또한 교차점, 횡단보도, 도로표식등 그외의 장애물을 정확하게 식별이 되게끔되어야한다. 또한 도로조명의 기준은 주로 도면의 Brightness와 그의 균제도에 의해서 결정되어지지마는 이의 기준은 종래의 관습과 휘도측정의 복잡성으로 인하여 일응조도로 환산해서 표현하고 있으며 충분한 조도를 필요로하는 동시에 도로상호간에 있어서 일관성을 필요로 한다. 구미제국에 있어서는 1965년 C.I.E.의 권고안에 의해서 연구실시단계에 있으며 일본에서는 도로조명에 관한 Jis를 개정하였으나 아직 한국에서는 기준은 커녕, 도로조명자체가 비합리적으로 시설되어지고 있어 우선 대구시에서 주요한 도로에 개시설된 도로조명에 대한 분석과 C.I.E.의 기준에 의한 합리적인 도로조명설계및 고속도로조명에 대한 고찰을 기하고자한다.

기존 유선망 중심의 스마트시티 플랫폼과 달리 무선 통신 모듈을 가지고 있는 정보 수집 장치들과 연동할 수 있는 5G 스마트시티 융합서비스 플랫폼은 도시내 설치된 다양한 무선 정보 수집 장치들을 통하여 수집된 정보를 기반으로 분석된 각종 정보를 제공해 주는 시스템이다. 도시 정보 수집 장치들 중에는 5G 지능형 CCTV 가 있으며 이를 통해 수집되는 영상 이벤트 정보를 기반으로 도로 안전 서비스 제공을 위한 이벤트 수집/필터링/대응 기능을 통하여 도로 안전 서비스를 제공해 주는 시스템을 설계하고 개발하여 적용함으로써, 도시내 도로 안전 수준을 높이는 것으로 목적으로 하고 있다. 본 논문에서는 도로 안전 서비스 제공을 위한 기능 모듈 구성에 대해 기술하고 해당 모듈들을 통하여 제공되는 도로 안전 서비스 실증 사례를 제시하고자 한다.

Because of road construction and expansion, Update of the road traffic facilities DB is steadily increased each year, and, Increasing drivers and cars, safety signs for traffic safety are required management and additional installation continuously. To update Safety Sign database promptly, we have developed auto recognition function of safety sign, and analyzed coordinates accuracy. The purpose of this study was to propose methods to update about road traffic facilities efficiently. For this purpose, omni-directional camera was calibrated for acquisition of 3-dimensional coordinates, integrated GPS/IMU/DMI system and applied image processing. In this experiment, we proposed a effective method to update database of road traffic facilities for digital map.

Generally speeding appeared to be the most contributing factor of fatalities occurred in work zones, and highway agencies in South Korea have concerned of the safety of workers and drivers in the poor circumstances. In this study, a portable variable message signs (PVMS) system as an alternative of control speeding in work zones was implemented. This study evaluated the safety effectiveness of the PVMS based on speeds and the compliance with the speed limit. Linear regression and logistic regression models were adopted to quantify the safety effect of the PVMS between the 'before' and 'after'. The results showed that most of points had statistically significant speeds reduction experience after PVMS installation. Also, the percentage of vehicle exceeding the speed limit by 10 km/h or more was decreased significantly between 50 and 80% in the 'after' periods compared to the 'before' periods. Therefore, the PVMS would be contributed to benefit safety in work zones which there is a difference in design speed of the adjacent normal section.

The railway crossing is very dangerous because the track intersects with the road there. Thus, The laws were designed for safety of the railway crossing and they are classified as to the acts for the road and the railroad. For safety of the railway crossing, there are 'Road/Railroad Crossing Improvement Promotion Act', 'Enforcement Decree of Road/Railroad Crossing Improvement Promotion Act', 'Rules on Construction of Railroad', 'Rules on Safety Standards of Railroad Installations', and 'Enforcement Ordinance of Cable way/Railway Track Act' in the acts for the railroad and there are 'Road Traffic Act', 'Enforcement Ordinance of The Road Traffic Act', 'Ruled on Structure and Facility Standards of The Road', 'Rules on Structure And Facility Standards Of The Rural Road' and 'Rules on Structure and Facility Standards of The Installations for Bicycle' in the acts for the road. Both the acts for the road and the railroad have standards for the structure of the railway crossing. However, they have different standards. Besides, they don't have standards for new facilities which were recently installed for safety of the railway crossing. Therefore, we suggest new standards for safety of the railway crossing.

Five bases for of highways are sight distance, vehicle stability, driver comfort, drainage and aesthetics. Among these bases, the sight distance is the most critical one in the highway alignment design. It is certain that highways and drivers' observation actions are 3-dimensional in nature. But, the highway alignment design and the sight distance analysis have been performed on 2-dimensional planes because of various constraints and complexity of calculating 3-dimensional sight distance. The purpose of this study is to derive a model for determining exact available sight distance in 3-D combined horizontal and vertical alignments. Application of the model is illustrated using numerical examples. The proposed model should be useful in quantifying the criteria for 3-D highway alignments.

The objective of this study is to provide systematic design of the Korea's Integrated Road Transport System in intelligent transport systems. Integrated Road Transport System services support safety driving and traffic information for travellers, and rapid response of the system for emergency status not only dissemination of traffic for traffic but also flood, heavy snowfall, falling rocks, closed-road, collapse, accident and so on. Therefore, integrated road transport system service contributes national highway safety management system to the voice of the nation of integrated road transport system center service for user friendly.
