The introduction of coastal vessel traffic services enables vessels in coastal waters to navigate in safety or to get her position with ease and prevents the vessel from becoming cause of casualties. But it needs relatively huge amount of cost to construct and operate and maintain. Thus we must be checked with economical adequacy of the the proposed coastal vessel traffic services by comparing the cost of the construction, operation and maintenance with the expected benefit made by the expected decrease in marine casualties. In previous paper, a proper cost-benefit analysis model for the Korean practice will be suggested. In this Paper, the proposed the cost-benefit analysis model of coastal vessel traffic services was applied to the Koje coastal waters 20mi1es from the top of Maemul-Do and Yokchi-Do. As the result, we confirmed the propriety of the cost-benefit analysis with the application of the proposed model to Koje waters. Also, it is verified that the introduction of coastal vessel traffic services, as proposed, is adequate and economical. The cost-benefit analysis model proposed in this study could be used to investigate the economic Propriety of new aids to navigation and traffic safety facilities in the future.

이 연구는 항만교통정보센터의 시스템 확충 및 연안 선박교통관리제도의 도입에는 많은 비용이 소요되기 때문에 비용과 편익을 비교하여 타당성을 조사하고자 한다. 따라서 비용과 편익을 분석하는데 중요한 기초자료가 되는 사고예방효과를 추정하고자 한다. 추정의 방법은 거제해역에서 발생한 해양사고를 분석하여 원인요소를 도출한 후 이를 설문문항으로 구성하여 항만교통정보센터의 운영요원을 대상으로 설문을 실시한다. 연안 선박교통관리제도의 도입에 의한 사고예방효과는 충돌사고에서 55.572%, 좌초사고에서 51.667%로 추정되었다. 또한 인적요소와 환경요소에 의한 효과는 높지만 기술적 요소에 의한 효과는 미미한 것으로 분석되었다.

이 연구는 연안 VTS의 타당성을 검토하기 위한 비용편익분석모델을 제안한다. 특히 모델의 가장 중요한 요소인 비용과 편익의 항목 및 정량화 방법을 세분한다. 제안한 모델은 연안 VTS를 포함한 대형 해상교통안전시설의 타당성을 분석하고, 그 우선순위를 결정에 활용될 수 있을 것이다.

The fundamental objectives of vessel traffic services (VTS) are the safety of traffic, efficient traffic flow and the protection of marine environment. And the coverge of VTS is used to be within the port and their approaches. It , however, is tend to expand the coverge beyond the radar coverage and the vessel carrying dangerous cargo. Therefore this study aims to investigate the international tendancy of the extended VTS system, and take a field test of using KOREASAT for the extended VTS system in Korean coastal waters. As the results of the test, KOREASAT is proved to be one of the alternatives for extended VTS system.
