해상교통관제는 관제사의 업무 특성과 작업 환경에 따라 제공되는 서비스의 질이 달라질 수 있다. 본 논문에서는 해상교통관제사의 근무 여건을 분석하여 추후 대한민국 해상교통관제 작업 환경 개선과 이를 통한 양질의 서비스 제공을 실현할 수 있는 방안을 제시하고자 하였다. 전국 20개소의 해상교통관제 센터에서 근무하고 있는 관제사를 대상으로 근무 여건 문제점 및 개선방안에 대한 인식을 설문하였다. 해상교통관제사의 작업 환경과 작업 스트레스, 이직의도 등을 분석하여 향후 해상교통관제 센터의 작업 환경과 조직 개선을 위한 기초 자료로 사용할 수 있을 것으로 기대한다.

우리나라 항만의 최근 5년간 항만별 입출항척수, 대형선박 통항 비율, 위험화물 운반선 통항 비율 및 해양사고 발생 현황을 통하여 항만별 해상교통 위험도를 식별하였다. 이와 함께 해상교통관제 구역에 대하여 기초 조사를 실시하여 현재 VTS센터에 설정된 관제구역 수가 이러한 해상교통 위험도 인자들과 비교하여 적정하게 설정되어 있는지를 검토하였다.

Vessel Traffic Service (VTS) is being used at ports and in coastal areas of the world for preventing accidents and improving efficiency of the vessels at sea on the basis of "IMO RESOLUTION A.857 (20) on Guidelines for Vessel Traffic Services". Currently, VTS plays an important role in the prevention of maritime accidents, as ships are required to participate in the system. Ships are diversified and traffic situations in ports and coastal areas have become more complicated than before. The role of VTS operator (VTSO) has been enlarged because of these reasons, and VTSO is required to be clearly aware of maritime situations and take decisions in emergency situations. In this paper, we propose a prediction table to improve the work of VTSO through the Cognitive Work Analysis (CWA), which analyzes the VTS work very systematically. The required data were collected through interviews and observations of 14 VTSOs. The prediction tool supports decision-making in terms of a proactive measure for the prevention of maritime accidents.

The national VTS was launched in 1993, and has adopted a harbour-oriented control method which is unable to consider enough characteristics of its work. However, for the past 17 years, the characteristics has changed due to increased amount of vessels. Up to now the domestic Vessel Traffic Service has adopted harbour-oriented control method which is unable to consider enough characteristics of its work. However, developed countries have carried out waters-oriented control method, according to the using areas of ships, to be well considered the characteristics of control for increasing efficiency of it. Especially, VTS of Daesan, Pyeongtaek and Inchon harbour can have confusions of control because of overlapped service areas of it. Therefore, in this paper suggested a new Sector Division that the relevants waters is divided into 3 operational Regions and these are divided into nine sectors again, for the purpose of improving the efficiency and the concentration of VTS.

A ship's sailing route or plan is determined by the master as the decision maker of the vessel, and depends on the characteristics of the navigational environment and the conditions of the ship. The trajectory, which appears as a result of the ship's navigation, is monitored and stored by a Vessel Traffic Service center, and is used for an analysis of the ship's navigational pattern and risk assessment within a particular area. However, such an analysis is performed in the same manner, despite the different navigational environments between coastal areas and the harbor limits. The navigational environment within the harbor limits changes rapidly owing to construction of the port facilities, dredging operations, and so on. In this study, a support vector machine was used for processing and modeling the trajectory data. A K-fold cross-validation and a grid search were used for selecting the optimal parameters. A complicated traffic route similar to the circumstances of the harbor limits was constructed for a validation of the model. A group of vessels was composed, each vessel of which was given various speed and course changes along a specified route. As a result of the machine learning, the optimal route and voyage data model were obtained. Finally, the model was presented to Vessel Traffic Service operators to detect any anomalous vessel behaviors. Using the proposed data modeling method, we intend to support the decision-making of Vessel Traffic Service operators in terms of navigational patterns and their characteristics.

The use of satellite remote sensing in maritime safety and security can aid in the detection of illegal fishing activities and provide more efficient use of limited aircraft or patrol craft resources. In the area of vessel traffic monitoring for commercial vessels, Vessel Traffic Service (VTS) which use the ground-based radar system have some difficulties in detecting moving ships due to the limited detection range. A virtual vessel traffic control system is introduced to contribute to prevent a marine accident such as collision and stranding from happening. Existing VTS has its limit. The virtual vessel traffic control system consists of both data acquisition by satellite remote sensing and a simulation of traffic environment stress based on the satellite data, remotely sensed data. And it could be used to provide timely and detailed information about the marine safety, including the location, speed and direction of ships, and help us operate vessels safely and efficiently. If environmental stress values are simulated for the ship information derived from satellite data, proper actions can be taken to prevent accidents. Since optical sensor has a high spatial resolution, JERS satellite data are used to track ships and extract their information. We present an algorithm of automatic identification of ship size and velocity. This paper lastly introduce the field testing results of ship detection by RADARSAT SAR imagery, and propose a new approach for a Vessel Monitoring System(VMS), including VTS, and SAR combination service.

선박 교통의 안전을 확보하고 항만의 효율성의 제고, 해양사고예방 및 해양환경 보호의 역할 기능으로 오늘날 해상교통관제의 중요성이 증대되고 있는 실정이다. 하지만 해상교통관제 운영의 법적근거가 미흡하여 적극적 체계적 관제 시행이 어려운 것이 현실이다. 이러한 해상교통관제 제도 선진화에 따라 관련 규정의 재정비는 필연적인 것으로 보인다. 따라서 본 연구는 현재 우리 나라 관제대상 선박의 적절성을 검토하고 나아가 관제대상 선박 적정 규정에 관한 지향점을 제시하기 위한 기초 연구로 삼고자 한다. 전 세계 27개국 124개 지역을 대상으로 조사한 관제대상 선박기준을 조사하여 우리나라 각 지방해양항만청의 관제대상 선박기준과 비교 분석을 통하여 적절성을 검토를 하고자 한다.

Recently IMO and IALA have developed the strategy of e-Navigation and the concepts of VTM to enhance the safety, efficiency and security of vessel traffic and protection of the marine environment. And current technical and functional trends require vessel traffic management systems to be improved so as to control vessel traffic not only in waters of harbour area, but also within EEZ waters. Under the consideration of these circumstances, a three-layered vessel traffic management system was proposed in this paper. The proposed system consists of three sub-systems, called Local VTS, Regional VTS and National VTS, and those sub-systems are designed respectively to be suitable for managing vessel traffic within their own jurisdiction waters.

From the 1978 Seasat synthetic aperture radar(SAR) to present systems, spaceborne SAR has demonstrated the capability to image the Earth's ocean and land features over broad areas, day and night, and under most weather conditions. The application of SAR for surveillance of commercial fishing grounds can did in the detection of illegal fishing activities and provides more efficient use cf limited aircraft or patron craft resources. In the area of vessel traffic monitoring for commercial vessels, Vessel Traffic Service (VTS) which uses the ground-based radar system has some difficulties in detecting moving ships due to the limited detection range cf about 10 miles. This paper introduces the field testing results of ship detection by RADARSAT SAR imagery, and proposes a new approach for a Vessel Monitoring System(VMS), including VTS, and SAR combination service.
