At the adjacent sea area of Busan Central Wharf, a variety of vessels, such as middle-large passenger ships, small fast sailing ships, container ships, cargo ships and working ships as well as small miscellaneous vessels are freely sailing comparatively without special steering and sailing Rules and marine traffic control because exclusive wharfs in accord with their purpose and use have been arranged in each wharf. In this research, we analyzed traffic stream and navigational characteristics of main traffic route based on statistics and distribution of tracks by ship's type and tonnage of the passing vessels after conducting marine traffic survey twice using exclusive software by targeting the sea area during the period of time. We examined the traffic safety of the passing vessels by classifying the sea area by each function based on the analysis about this traffic situation, and analyzing the effect by designating 'Buknea passage'. We also studied the plan for the effective rearrangement of Central Wharf considering basically the traffic safety oif arrival and departure in a point if view of navigators.

As a preliminary study of enter or leaving traffic patterns of the Korea main port, port Management Information System (Port-MIS) data was used to check the volume of vessels entering and leaving the port of Busan, and three consecutive days from each seasons were selected for study. Selected 12-day General Information Center on Maritime Safety & Security (GICOMS) data was also used to analyze the traffic pattern in the main traffic lane of Busan port for dangerous goods carrier. Also, the distance between dangerous goods carriers and Oryukdo breakwater of east breakwater in the main traffic lane was analyzed. Collision probability was estimated using the cumulative probability distribution function of the normal distribution for the maritime traffic safety audit scheme based on the assumption that a ship's trajectory has a normal distribution for a section of the route. However, in case of entry or leaving thorough the Oryukdo breakwater and entry thorough the east breakwater, ship's sailing trajectories were revealed not to follow a normal distribution via regularity testing using a KS-test and SW-test. Especially in the north port, the tendency of the right side of the ship to pass was remarkable. It is desirable to develop a traffic model suitable for the characteristics of the port rather than to apply general traffic theories, and to apply this model to a maritime traffic safety diagnosis, so further research is needed.

Gyeongin Ara Waterway will be open on Oct., 2011, Which is the first inland artificial waterway constructed in Korea. There have been arguments about the environmental issues and economic effectiveness, however, it's now time to focus on the safety of navigation at the waterway to protect human life, property and environment. Therefore this paper aims at examining the establishment of the rule of safe navigation and management for the safe and effective management of the waterway and tries to draft the rules based on these examinations. The draft rule consists of 7 chapters, which are general rules, general rules on navigation, specific rules on navigation, general restrictions, emergency response, restrictions on navigation and penalties in consideration of the characteristic of Gyeongin Ara Waterway and regulations on navigation in major canals in the world.

In these days, several bridges have been built or under construction over navigational channel in Korea In these cases there must be careful consideration for the marine safety of vessels to be passed by below the bridge. This paper aims to analyze the factors influencing maritime traffic safety and to figure out ample width of main span of these kinds of bridges through the reference study and FMSS.

해상교통안전성평가는 크게 해양 안전 및 환경측면에서, 세부적으로는 해당해역의 특성을 파악하여 항로수립, 해상교통안전진단 및 해상교통영향평가 등을 수행 하는 측면에서 중요하다. IWRAP은 IALA Waterway Risk Assessment라는 평가도구로 항만수로의 위험도(선박의 충돌 및 좌초확률)를 분석하는 정량적인 평가모델이다. 정량적인 해상안전 평가방법은 통항량, 선속, 길이, 선박의 통항분포로부터 해상에서 통항의 위험도를 평가하므로 인적, 지리적, 환경적 등 주관적인 요소들이 많은 정성적인 평가방법에 비해 적용이 간단하다. 본 연구에서는 IWRAP을 해상교통안전진단제도로의 활용을 위해 목포항 진입수로를 대상으로 IWRAP분석을 하여 그 실효성을 평가 하고자 한다.

국제 해상물동량(해상화물 수송량은 10년 사이에 매년 평균 4.3%씩)의 증가에 따라 해양사고의 발생 빈도도 높아지고 있으며, 사고의 규모도 대형화 되고 있는 추세이다. 이에 따라 해상에서의 선박 위험도 저감을 위한 많은 시스템들이 개발/운영되고 있지만, 대부분 실시간 위치정보를 기반으로 충돌위험 등을 분석하고 있고, 선박간의 충돌 외의 선박의 주변 환경에 대한 고려는 미비한 실정이다. 실제 해상에서의 통항량 및 10년간 사고를 분석하여, 충돌등 사고가 많은 남동부 해역(여수/통영/진해)의 통항패턴, 교차구역 및 해양사고 특성을 분석해보고, 이에 따라 Sector별 특징적 집중 관제 방안을 마련하여, 선제적 안전 서비스 방안을 연구하고자 한다.

일반적으로 항만 내 선박 교통류 평가는 AIS 데이터를 이용하여 수행이 되어져 왔다. AIS 데이터는 선박의 위치 확인에 용이하여 항로상 선박 교통분포 분석에 용이하였다. 하지만, AIS 데이터는 VTS에 저장되어 있는 기간이 짧고, 처리할 데이터의 양이 많은 단점이 있다. 한편, PORT-MIS 선박 입출항 데이터는 10년 이상 저장이 되어 있으며, 통항로상 통계적 선박교통밀도 분석에 활용이 용이하다. 본 연구에서는 PORT-MIS 빅데이터 분석 방법과 선박 입출항 데이터를 항로상의 통항데이터로 변환하는 방법을 개발하여 제시하고자 한다.

Maritime traffic assessment is important to understand the characteristics of maritime traffic and to prevent maritime accidents. The maritime traffic assessment can be calculated from the ship trajectory data observed by using AIS(Automatic Identification System). This paper developes a maritime traffic assessment tool using ship's position and speed, course, time data from ships navigating waterways. The results are represented in terms of the number of traffic quantity and traffic distribution, speed distribution, geometric collision candidates. The developed tool will contributes to advance maritime traffic safety by VTS(Vessel Traffic Services).

본 연구에서는 실제 AIS의 정적, 동적 데이터를 수집하여 항계내 통항 선박의 움직임을 파악하였다. 실제 완도항 부근의 직선항로을 통항하는 선박 항적의 분석하여 불규칙적인 선박의 특성을 알아보고자 하였다. 기존의 과거 누적 데이터의 퍼지이론을 활용한 이상 거동의 선박식별 시스템은 전문가 시스템에 의존하여 항적의 비정상성을 판단하므로 항로의 특성에 따른 실 항해상황을 간과할 수 있는 문제점이 있다. 본 연구는 실시간 AIS 정보를 활용하여 항로이탈의 변화율에 해당하는 곡률분석, 항로선으로부터 좌우의 변동을 보다 정확하게 모니터링 할 수 있는 이상 거동 선박을 식별하는 방법을 제안한다. 본 연구는 VTS 및 VMS의 응용서비스로서 해양사고의 사전예방을 위한 연안 및 항만수로의 효율적인 관리에 기여할 것이다.

For safe passing the waterway crossing bridge without collision with bridge-piers under poor visibility circumstances, it is very important that the pier should be detected definitely as earlier as possible by radar, In this study, the required length of Projecting part of the bridge pier for definite radar recognition was obtained by theoretical and experimental analyses. By presenting the required values depending on the maximum vessel size and passing condition, it is expected possible to design the bridge pier protecting system appropriately suitable to traffic environment of the waterway.
