  • To establish a vessel safety management system for improving the safety of vessel's traffic and preventing vessel's traffic accidents, the state of marine traffic in the Busan South Port was investigated and analyzed as preliminary survey of the countermeasures. As a result of the study, there are 1,158 vessels in a day, 48 vessels in an hour, and the maximum traffic is about 118 vessels between 16:00 and 17:00 hours everyday, which requires to establish and operate a traffic control system necessarily for ensuring vessel's traffic safety. Furthermore, passages of tanker, passenger ship, cargo vessel and government vessel showed to sail along main traffic lane to be obtained enough sea depth at the survey area. However, passages of fishing vessel and launch showed to sail freely at all survey area owing to outstanding maneuverability and a shallow draft. Some vessels of launch sailed along main traffic lane, but other vessels crossed to sail it. The passages to cross main traffic lane is higher the risk of collision. Therefore, safety measures are urgently needed for the operation of the Busan South Port management system and the prevention of marine pollution.

  • 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.

  • Vessel traffic safety management means the managerial technical measures for improving the marine traffic safety in general terms. The main flow of vessel traffic safety management is that: 1) Traffic Survey, 2) Replay by Marine Traffic Flow Simulation, 3) Quantitative Assessment, 4) Policy Alternatives, 5) Prediction·Verification. In the management of vessel traffic safety, it is most important to establish assessment models that can numerically estimate the current safety level and quantitatively predict the correlation between the measures to be taken and the improvement of safety and the reduction of ship handling difficulties imposed on mariners. In this paper, the replay model for traffic flow simulation was made using marine traffic survey data, and the present traffic situation became replay in the computer. An attempt was made to rate the current safety of ports and waterways by applying the Environmental Stress model. And, as a countermeasure for traffic management, by taking of, the promotion of total traffic congestion in early morning rush hour, the correlation between traffic control rate and the reduction in ship handling difficulties imposed on mariners was predicted quantitatively.

  • 본 연구에서는 대정해상풍력단지 설치 해역과 인근수역을 이용하는 선박교통량과 해상교통흐름의 패턴을 분석하고 단지 조성 후 합리적인 대체통항로 지정에 따른 교통량을 예측하였다. 또한 예측된 교통량을 근거하여 통항로별 통항안전성을 평가하고 검토함으로써 선박의 안전운항에 필요한 제반조건 및 대책을 제시하였다. 풍력단지 설치 해역과 인근수역의 해상교통흐름 패턴을 분석한 결과 총 8가지의 교통흐름으로 분류되었고, 연간 교통량은 8,975 척으로 예측되었다. 이를 근거로 단지 조성 후 4가지의 대체 통항로 지정에 따른 교통량을 예측하였다. 예측된 교통량과 SSPA의 동력선충돌모델을 이용하여 통항안전성을 평가한 결과 충돌 및 침로이탈확률에 관한 국내 안전기준 $10^{-4}$ 이하를 만족하므로 계획된 대체통항로가 유용함을 확인하였다.

  • Accurate vessel traffic observation is indispensable to carry out vessel traffic management, design of vessel traffic route, planning of port construction, etc. In order to observe the vessel traffic accurately without many efforts such as the use of a ship or car equipped with special radar observation system and the preparation of observation staff, the authors have been developing completely automated remote radar/AIS network system covering the main traffic area in Tokyo Bay. The composite radar image observed at Yokosuka and Kawasaki radar stations with AIS information can be seen on web site of Internet. In addition to the development of radar/AIS observation system, the software to analyze observed vessel traffic flow has been developed. This software has various functions such as automatic tracking of ship's positions, automatic estimation of ship's size, automatic integration of radar image and AIS data, animation of ships' movements, extraction of dangerous ship encounters, etc. The configuration and functions of the developed remote radar/AIS network system are shown first in this paper. Then various functions of the software to analyze vessel traffic are introduced, and some analyzed results on the vessel traffic in Tokyo Bay are described demonstrating the effectiveness of the developed system.

  • 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.

  • 해상교통량 조사 분석은 안전하고 원활한 항로 항만의 설계와 제반시설의 개선 및 항행관리를 위하여 반드시 필요한 수단이다. 해상교통량 조사 분석과정에서 정확한 조사방법을 통해 선박통항에 관한 데이터들을 수집하여야 하고, 수집된 선박교통량에 관한 다양한 정보는 정확하고 과학적으로 분석되어야 한다. 이 논문에서는, 해상교통량 조사과정에 있어 인력에 의해 일어날 수 있는 오차를 보완할 수 있으며, 정확한 조사의 실행 및 분석결과를 출력할 수 있는 시스템을 연구 제작함을 목표로 한다. AIS 및 전자해도를 기반으로 하여 정확하고 신속하게 선박교통정보를 수집하여 조사분석자의 수고를 경감시켜줄 수 있으며 표준화된 분석결과를 제시해줄 수 있는 해상교통량 분석 시스템을 제안하고 그 개발 내용을 소개하고자 한다.

  • The maritime traffic system research has been studied for the safety and efficiency of the Marine Navigation. In order to evaluate the maritime traffic system, the vessel traffic observation is playing important roll. Recently, the way of collecting the vessel traffic information has been become fixed by using the radar, the AIS and the visual observations. However, it is still difficult to get the information about ships without the AIS. In this paper, the past vessel traffic observation results are shown. From those data and introducing the way of Japanese traffic survey, the recent matters of the vessel traffic observation are discussed.
