The preliminary study was conducted on the use of navigation instruments and programs conducted in the previous demonstration and experiment of the training ship SAEBADA, real-time sharing and accuracy of land and sea information, and the development of real-time effective information transmission and reception and management system programs. Based on this, this study used the training ship CHAMBADA, which is similar in length to the tonnage of the fishing boat. The purpose is to present errors in ship situation-specific information data, alarm systems for marine information, and land and ship transmission and reception programs collected using intelligent information management systems to find out whether they can be applied and used in fishing boats. It plans to conduct research on direct and indirect safety and ship’s stability when the intelligent information management system operates in real time in the operation of ships considering the characteristics of small fishing boats and the characteristics of fishing.

PURPOSES : This study focuses on advance traffic information to prevent secondary traffic accidents on express highways. The purpose of this study is to analysis the optimal scenario by evaluating the effect of each advance traffic information scenarios using virtual driving simulation. METHODS : By designing traffic information scenarios and services with a combination of VMS and mobile PUSH notifications, driver behavior in the event of a traffic accident was analyzed. For this, a simulation environment was designed through engineering analysis. Through virtual driving simulation, the driver's deceleration point and the perception-reaction time are analyzed. RESULTS : Four scenarios were designed and reviewed so that VMS and mobile PUSH notification can be provided simultaneously after the driver drove for 5 km. As a result of driving with 30 drivers, the drivers reacted fastest when VMS was installed, followed by mobile PUSH notification, VMS+mobile PUSH notification, and NOTHING. CONCLUSIONS : When designing traffic information service, it was observed that providing information through VMS alone is more efficient than providing two services of traffic information. Therefore, it can be used as basic data for preventing secondary accidents on express highway.

In order to develop an HNS safety management system to assess and visualize hazard levels via an automated method, we have conceptualized and configured a sample system. It is designed to quantify the risk of a vessel carrying HNS with a matrix method along navigational route and indicate hazards distribution with a contour map. The basic system which provides a visualized degree of hazards in real time has been introduced for the safe navigation of HNS ships. This is useful not only for decision making and circumstantial judgment but may also be utilized for HNS safety management with a risk base. Moreover, this system could be extended to address the navigational safety of marine traffic as well as of autonomous vessels in the near future if the sensors used are connected with IoT technology.

현재 우리나라에서 자전거를 편리하게 이용할 수 있도록 전국 주요 도시를 자전거 길로 연결하는 국가 자전거도로 사업을 추진하고 있다. 그러나 자전거도로의 안전성 및 내구성을 평가할 수 있는 방법의 미비로 자전거도로의 성능을 정확하게 파악하지 못하여 기술력의 향상을 꾀할 수 없고 시공 시 품질관리에 많은 어려움을 겪고 있는 상황이다. 특히 노면의 미끄럼은 사고 발생과 밀접한 관계를 가지며, 우천 시에 미끄럼저항성이 저하되는 특성으로 자전거도로의 안전도 평가에 있어서 매우 중요한 요소이다. 또한 오늘날 자전거의 제조기술의 향상으로 자전거 주행속도가 증가되어 과거보다 미끄럼저항에 대한 중요성이 부각 되고 있다. 따라서 본 연구에서는 미끄럼저항 성능 기준의 적정성을 검토하기 위해 미끄럼저항 국내·외 기준을 비교 분석하였으며, 실제 현장에서 미끄럼저항을 측정하고, 자전거 제동시험을 통해 자전거 포장 종류 별 미끄럼저항 성능을 분석하였다.
