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.

Part 2 of the Questionnaire Survey on Marine Safety and VTS in the Philippine Coastal Waters presents the alternatives to risk reduction, modifying the VTS, the qualification and competency of a VTS operator and effectiveness of the services and assistance rendered by VTS. This study finds that majority of respondents chose "Improved education and training of mariners" as the best alternative to risk reduction and the "Strict enforcement of ship safety regulations" as the best alternative based on the respondents' ranks last served onboard and areas of familiarity. In modifying the VTS, the areas with VTS chose to "Improve or upgrade" and for those without, is to "Implement" the system. The best VTS system is the "Port and Approaches" type and the PCG is selected to operate, maintain and supervise the system. As a VTS operator, the necessity of shipboard experience is considered "Essential" and the experiences include "Ship-handling and Communication", and "Management level" experiences. The effectiveness of the assistance and services rendered by VTS are considered "Very Important". Based on these findings, this study recommends improvement of education and training of mariners and users of the waterways including the training of VTS operators manning the VTS centers, strict enforcement of ship safety regulations along the busy and main ports of the country and installation of VTS system with the most appropriate type with the supervision of PCG.

The question of recruitment qualification and standardization of VTS operators is reviewed through comparison with Air Traffic Control(ATC) The comparison reveals greater difference between the two services than commonality. While ATC enjoys a high degree of uniformity nationally and internationally the provision of VIS is dictated by varying local needs. The variety of those needs makes standardization of VTS operation a questionable short term objective. The paper concludes problem solving techniques such as the formal appreciation provide means of matching recruitment and qualification to local requriements.

Vessel Traffic Service (VTS) is the service that provides ships navigating on a sea transportation route with guidance and advice about geographical environment and other attentive information for their safety. In this study we point out that currently, constructing additional VTSs is required to prevent ships from unexpected accident on their navigation. We first select several candidate locations for constructing VTSs, based on the amount of marine transportation and its potential development possibility. Then, we present an optimization model in which the maximum area coverage is achieved by determining new locations of VTS subject to budget limitation. The problem can be modeled as a binary integer program and it provides an optimal solution for new VTS locations to be constructed under the consideration of the currently located VTSs in Korea.

With the expansion of the shipping and port logistics industry in the 21st century, the traffic density is continuously increased because of the increase in volumes of world sea freight and fleets, as well as the increase in the causes of potential marine accidents, such as ship collisions and stranding. Accordingly, the International Maritime Organization (IMO) has requested that the installation and operation of VTS should be applied in areas with high risk of marine traffic, and the request should be included as one of the Safety of Life at Sea (SOLAS) regulations. In this paper, the fundamental requirements of the radar system for vessel traffic services were analyzed and the analyzing factors were based on the IALA guideline.s This paper also includes results for the requirement and recommendation analysis on detection distance, target separation, and the target position accuracy of X-band radar. Also, to check if it satisfies the requirement of detection distance, range and azimuth separation of small point targets, and target position accuracy from the IALA guidelines, the test was conducted through the radar image acquired at the VTS center, and hence, the validity of the technical performance requirements was confirmed.

The purpose of this paper is to describe the brief history of VTS in Korea including traffic separation scheme(TSS) and vessel movement reporting scheme(VMRS) in earlier time. The effectiveness of existing traffic services in Korean waters in mentioned in comparison with the results of other countries. Advanced VTS has been introduced in 1993 at the port of Pohang and thereafter a national VTS programme is developing to introduce the state-of-the-art system into major ports and their approaches including Yosu/Kwangyang Inchon and Pusan. This paper introduces the future expanding VTS programme is Some recommendations are made to enhance the traffic safety in Korean waters and to increase the effectiveness of the advanced VTS.

IVEF 서비스는 해상교통관제시스템 상호간, 선박 상호간에 해상교통정보를 교환하기 위한 표준안으로서 e-Navigation이라 불리는 차세대 선박항법체계의 일환으로 표준화가 진행 중에 있다. 국제항로표지협회 IALA는 V-145 권고안을 통해 IVEF 서비스 모델과 서비스 제공을 위한 프로토콜을 제시하고 있으나 구체적인 구성은 이를 이용하는 사용자가 설계하여야 한다. 본 논문에서는 V-145 권고안의 기본 서비스 모델과 프로토콜을 토대로 해상교통정보의 교환을 편리하게 해주는 J-VTS 미들웨어를 설계하고 구현하였다. J-VTS 미들웨어는 IVEF 서비스를 제공하기 위한 다양한 컴포넌트들과 IVEF 메시지 프로토콜을 처리하기 위한 컴포넌트들로 구성된다. 상위 애플리케이션에 해당하는 해상교통관제시스템과 선박들은 J-VTS 미들웨어에서 제공하는 함수들만을 이용하여 편리하게 IVEF 서비스를 이용할 수 있도록 설계 되었으며, 접속자의 보안등급에 따라 서비스가 단계적으로 제공되게 된다.

선박교통류 평가는 대상해역 해상교통특성 파악을 통하여 정량화된 체계화된 교통관리를 수행함으로써 해양사고를 예방하는데 중요하다. 해상교통류의 특성은 선박자동식별장치(AIS, Automatic Identification System)가 선박에 설치됨에 따라 이 장치에서 수신된 정보를 토대로 평가할 수 있다. 본 연구에서는 해상교통관제센터(VTS, Vessel Traffic Services)에서 선박으로부터 수집된 위치, 속력, 침로, 시간 정보로부터 항로상에 해상교통류를 평가하기 위한 시뮬레이터를 구현하였다. 그 결과 해상교통관제센터에서 수집된 데이터로부터 선박 통항량, 통항분포, 선박속력분포, 기하학적 충돌빈도가 계산되어 표시된다. 이러한 해상교통류평가 평가는 해상교통관제사가 해상교통관리의 관점에서 해상안전을 위한 서비스를 제공하는데 유효하게 활용될 수 있을 것으로 사료된다.

IMO에서 개발 중인 e-Navigation 전략 이행 계획에는 VTM(Vessel Traffic Management)을 핵심 요소들 중 하나로 포함시키고 있다. E-Navigation이 지향하는 VTM은 현재 VTS보다 다양하고 정확한 항행 정보를 선박에 제공하고 적극적 관제를 통하여 안전하고 효율적인 해상교통 흐름을 유지시키는 개념을 갖고 있다. IMO에서 계획하고 있는 VTM 기능을 구현하기 위해서는 VTS 운용 요원인 관제사들의 역할 및 능력이 VTM의 성공 여부를 좌우한다. 따라서, VTM의 구현을 위해서는 VTM에 있어서 관제사들의 역할과 관제사들의 VTM 수행을 위한 자질 능력 향상을 위한 교육 훈련 방안이 함께 논의되어야 한다. 본 연구에서는 e-Navigation 환경 하에서 VTS 관제사가 안전하고 효율적인 VTM을 수행할 수 있도록 관제사를 지원하는 관제사 의사 결정 지원 시스템에 대한 개념 설계를 수행하였다. 본 논문에서는 관제사 의사결정 지원 시스템의 개념, 주요 기능, 구성 요소 및 이를 구현하기 위한 요소 기술들에 대해 기술하였다.
