The International Association Marine Aids to Navigation and Lighthouse Authorities (IALA) proposed guidelines for VTS manual operation in 2016 for safe and efficient operation of ship. The Korea Coast Guard (KCG) established and operated 19 VTS centers in ports and coastal waters across the country by 2022 based on the IALA VTS manual and VTS operator's education and training guidelines. In addition, IALA proposed the Inter-VTS Exchange Format (IVEF) Service recommendation (V-145), a standard for data exchange between VTS, in 2011 for efficient e-Navigation system services and safe and efficient VTS service support by VTS authorities. The IVEF service in a common framework for ship information exchange, and it presents seven basic IVEF service (BISs) models. VTS service providers can provide safer and more efficient VTS services by sharing VTS information on joint area using IVEF standards. Based on the BIS data, interaction, and interfacing models, this paper introduced the development of the cloud-based VTS integration services performed by the KCG and the results of the VTS integration platform test-bed for IVEF service implementation. In addition, the results of establishing a cloud VTS integrated platform test-bed for the implementation of IVEF service and implementing the main functions of IVEF service were presented.

This study aimed to specify Vessel Traffic System(VTS) operators' situational awareness(SA) tasks and examine differences in subjective ratings for three levels of SA. Data for relative frequencies of SA tasks were collected by using direct in field observation. Subjective rating scores were obtained using a questionnaire method and compared in terms of VTS operator's gender and length of service career. The results are as follows. First, it was found that the VTS operators perform information perception task elements more frequently than those for information integration and prediction. Second, VTS operators tended to show subjectively lower evaluation scores for prediction than information perception or integration. Third, male VTS operators rated their SA ability higher than females. Fourth, the male VTS operators more than 15 years of career service showed higher subjective rating scores than those with under 5 years of service. Female VTS operators with different levels of career service showed a similar level of subjective rating scores. These results suggest that the frequency of SA related tasks and subjective SA evaluation can differ in terms of SA levels and individual differences.

Although it is expected to provide fundamental data for advanced VTS system by analyzing traffic accidents in VTS area, there is no quantitative analysis to find it.. In this research, it is examined and analyzed marine casualties records(1999-2004), data of Port-MIS and data of each VTS center. The results of this research are as below. 1) It is necessary to reduce traffic accident and to improve VTS operating system. 2) It is discovered for statistical discrepancy between vessels controlled by VTS and vessels not controlled by VTS in accident cause, visibility, perception distance and cause of late perception in collision accidents 3) It is necessary for VTS assistance to be positive and to made in ample time consecutively. 4) As the result of traffic accident prediction model, it is necessary to develop a system improving VTS operators' ability to identify dangerous ships.

해상교통관제센터(VTS)는 해상 안전과 선박교통효율을 위해 우리나라 주요 항만 및 연안해역에서 운용중이다. 우리나라 VTS는 외국항만 VTS에 비해 1인당 담당 관제면적이 넓으며, 최근 VTS 구역 추가 확대로 기존 관제사의 담당구역이 기존보다 더욱 확대되어 관제사의 집중관제와 선박교통관리 어려움이 더욱 증가되고 있다. 이에 따라 VTS 구역의 효율적인 운영과 VTS 인력 확보를 위한 정량적인 관제석 수 산출이 필요하다. 본 연구에서는 VTS에서 수집중인 선박교통 및 선박교신 데이터를 이용하여 VTS 구역 적정 관제석 산출방법을 제안하고자 한다. 제안한 방법은 VTS 구역에서 운항하는 모든 선박의 모니터링 시간, VHF 교신에 대하여 관제 업무(task)항목, 출현빈도, 소요시간을 정의하고, 단위시간동안 각 관제 task별 소요시간을 계산하여 관제석 수를 계산한다. 제안한 방법을 여수VTS 해역의 VTS데이터에 적용하여 적정 VTS 관제석 수, 시간대별 관제석 수 변화를 분석하였다. 분석 결과 혼잡시간대 필요 관제석이 4-5 석이 필요로 한 것으로 분석되었다.

이 연구는 기존 VTS 시스템의 효율성을 증대시키기 위해 VTS 시스템에 선박조종 시뮬레이터를 기능적으로 연계시켜 VTS 시스템을 3차원으로 확장시키고자 시도된 것이다. 기존의 VTS 시스템은 ARPA Radar를 이용한 2차원에 국한된 관제 시스템이나 이 시스템에 분산처리 네트워크방식을 적용하여 3차원 기능을 가진 VTS 시스템으로의 확장이 가능하도록 하였다. 이러한 확장된 VTS 시스템의 운용은 선박의 안전운항에 큰 역할을 할 수 있을 것으로 기대된다.

우리나라는 1993년 포항항 VTS 센터를 시작으로 전국의 주요 항만과 연안, 내륙수로에 세계적 수준의 VTS 시스템을 구축하여 운영중에 있다. 하지만 높은 수준의 VTS시스템을 가지고 있음에도, 국제사회에서 VTS 업무협력 및 정책 홍보 등의 활동력은 상대적으로 빈약한 편이다. 현재의 우리나라 VTS의 조직, 예산, 인력 측면의 문제점을 살펴보고 향후 국제 VTS에서 주도적 역할과 위상제고를 위한 개선점을 살펴보았다.

The purpose of this study is to find out what is the functional role of VTS in order to get the people concerned with marine traffic/transportation understand about VTS. VTS could be described as the essential risk management system in both cost effective on cost-benefit analysis and the sea space or time management at port, coastal environment. The important role of the VTS are those functions such as the decision making infrastructure, the passive/active safety measures at sea. VTS could not control/regulate marine traffic as strong as ATC(Air Traffic Control) owing to the marine traffic characters. However, the right and responsibility of VTS finally are belong to the master, pilot and mariners. For the benefit of the electronic technology development, VTS system also cloud be upgraded to communication system from information system. In connection with these system upgrading, the right and responsibility of VTS/staff should be supported by domestic legal system. The followings are presented for VTS to be effective. First, the cooperation and understanding of VTS between the peoples concerned with marine traffic/transportation are essential. Because they are all data supplier and also information consumers. Second, VTS staff/regulator should be selected, educated, trained accordingly as per their career, ability, quality, qualification, certification and etc. Third, the port reliability from VTS users depends on the factors such as economic interests, safety and effectiveness/efficiency of VTS.

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.
