In the present maritime traffic conditions of Mokpo harbor, there exist many hazardous factors which may lead to huge accidents including marine oil pollution We analyze marine traffic environments including traffic congestion, natural conditions, maritime traffic accidents in the last 10 years, the fishery status, operation of traffic routes and management of navigational aids and regulations relating ships' routeing both in and out of the country. Consequently, this work is to propose improved marine traffic system in future.

해상교통을 모의하기 위해서는 주요 요소인 선박운항자의 인적요인에 대한 모델링 필요하며, 현실감 있는 해상교통 상황의 재현 및 예측을 위해 선박운항자 행동양식, 항해전문성, 항해오류 등을 모델링하여 반영하는 것이 필요하다. 본 발표에서는 에이전트 기반의 해상교통 시뮬레이션을 위해서 선박운항자의 충동회피를 위한 행동 분석를 수행했으며, 기초 데이터의 확보를 위해 설문조사를 실시하였다. 설문조사를 통해 분석된 정보를 이용하여 선박 충돌상황에서 선박운항자의 행동과 유사한 에이전트 기반의 항해행동 모델 개발현황을 소개하고자 한다.

물동량 증가로 인하여 부산신항에는 극초대형 컨테이너 선박들이 입항하고 있으며 서컨테이너 부두 건설 사업이 완료되면 부산신항 진출입 항로 내 다양한 조우 상황 발생으로 충돌 위험 상황을 초래할 수 있어 선박 통항 안전성 향상 방안 마련을 위하여 부산신항 내 항만 입출항 현황과 해상교통흐름을 살펴보았으며, AHP 기법을 활용하여 위험요소 및 안전대책 식별로 도출된 안전대책을 기반으로 환경 스트레스 모델을 활용하여 해상교통류 시뮬레이션을 실시하여 각 안전대책의 교통 위험도를 파악하였다. 설문조사 및 시나리오 평가 결과, 선박운항자는 일방통행을 위한 진입금지 해역 설정을 가장 중요하게 생각하였으며, 이는 위험도 경감에 큰 효과가 있을 것으로 예상되었다, 본 연구는 부산신항을 입출항 하는 선박들의 통항 안전성 제고를 위한 안전대책 마련의 기반이 될 수 있을 것이다.

Since special sea area for traffic safety has been established in 1988, there has been only deep water line for deep draft vessels and no other ships' routeing measure for special sea area on Yeosu Bay. In this work, we suggest several solutions to secure ship's safety and to eliminate dangerous factors which exists in present ship traffic system. Consequently, this work is to propose improved marine traffic system in future.

There has been only a deep water route for deep draft vessels without any other routeing system in Yosu Bay despite of the rapid change in ship's size and increase in the traffic volume since the specified area for traffic safety was established in 1988. In this work, we suggest several solutions to secure ship's safety and to eliminate dangerous factors which exists in present ship traffic system Consequently, this work is to propose improved marine traffic system in future.

In the present maritime traffic conditions of Gwangyang harbor, there exists many hazardous factors which may lead to huge accidents including marine oil pollution. To mitigate the danger to vessels in Gwangyang harbor and to secure the safety of maritime environment, we established one way traffic between No.3 Route and No.4 Route, Designed of deep water line on No.3 route, Extended one-way route for Myo-Do Passage etc.

Because of the continuous increase in the demand for and importance of marine space, marine exploration and survey activities are being actively conducted in Korea actively. Because the marine survey vessels used for these activities have special operational patterns depending on the purpose and probe vessels, research on maritime traffic risk is required. In this study, an attempt was made to determine the correlation of each factor with the effect of marine exploration and survey vessel operation on maritime traffic. The status of ocean exploration and survey vessels in operation in Korea was identified, as well as the special operational conditions of some of the ocean physical probes. Generally, the number of exploration and survey vessels involved per hour, total vessel length(including exploration equipment), operation, interval distance of exploration as per plan, and marine traffic conditions(traffic volume and speed) can be classified as operating factors. To compare the results of the environmental stress, a maritime traffic flow simulation based on the "ES" Model was performed with each of the identified operating factors as independent variables. The results of the analysis confirmed that the environmental stress significantly changed in the order of traffic volume, ship length and speed. In addition, it was confirmed that the environmental stress is reduced when the operation course is set at an angle with the nearby maritime traffic flow. Accordingly, it can help reduce the operator's burden if the survey vessel operator understands nearby maritime traffic conditions and reflects them in the operation method when setting the operation plan.

Marine traffic management could be defined as the implementation of managerial technical measures to improve vessel traffic safety. The managerial elements of vessel traffic management for ports and harbours or narrow channels include the total amount of traffic control, the vessel traffic separation scheme, speed restriction, traffic control by signals, the navigation information service and so forth. This research aims to quantify how much the traffic separation schemes(TSS) contribute to the alleviation effect of ship handling difficulty and to propose a design standard when the individual management measure is applied in an actual waterway. Traffic separation schemes have now been established in most of the major routes and congested waters of the world, and the number of collisions and groundings have often been dramatically reduced. In this part, the relationship between the alleviation of ship handling difficulty and the reduction of encounter figures among ships is quantitatively clarified by applying the ES model. As results of simulation analysis, it is recognized that a traffic separation system is most effective in the case of narrow width and heavy traffic volume. The centre buoy installation reduces about 1/4 of the alleviation of ship handling difficulty, TSS establishment 1/3, and design change to one-way traffic from two-way traffic reduces 1/2.

Marine traffics near Ulsan approaching waters are crossing and converged at the diverging point of No.1 route-No.2 route and No.1 route-No.3 route and are also concentrated at near No1. route approaching area and the headland of Gawn-Jel. Because the number of berth will increase to 78 from 49 until 2011 due to additional developments, minor modification is expected for the water utilities. This study examined environmental conditions, marine accidental data, marine traffic capacity, traffic flow survey and fisheries zone status near Ulsan approaching water area. Finally, a questionaire survey was carried out for experts and users to propose new plan
