It may be reasonable to consider density per unit area over time rather than analyze traffic volume, which is simply the traffic volume per unit of time, in assessing the maritime traffic congestion of a certain area. This study contributes to the standardization of maritime traffic congestion assessment methods for the maritime traffic safety diagnosis institute while seeking a new method to minimize evaluation error due to converted traffic volume per ship tonnage level. To solve this problem, a method to evaluate maritime traffic congestion by comparing the area occupied by a vessel with the area of its route using vessel identification data from the Automatic Identification System (AIS) has been proposed. In this new model, it is possible to use actual data due to the development of information and communication technology, reducing conversion error while allowing for the evaluation of maritime traffic congestion by route.

중대한 해양사고를 예방하고 잠재적인 해양사고의 원인을 제거하기 위하여 해상교통안전진단 제도가 "해상교통안전법" 개정('09. 5. 27)을 통해 정식 제도화되었다. 법 시행 이후 수행된 연구 중 하나인 '해상안전진단제도의 기술기준 및 고도화 연구'에서는 관련 평가 중 하나인 해상 교통혼잡도 평가에 사용되는 환산교통량 및 표준선이 현재 선박의 대형화 및 고속화 추세를 반영하고 있지 못함을 제시, 개선의 필요성을 말하였다. 이에 먼저 관련한 일본의 이론과 국내 진단대행업자의 평가 이론 현황을 파악 분석한 바, 이론 및 진단대행업자 별로 분석요소들을 다르게 사용하고 있어 표준화의 필요성을 발견하였고 또한 2010년 선박 입출항 통계를 이용한 선박현황을 분석한바 이론에서 사용하는 표준선과는 상당이 차이가 있음이 나타났다. 이후 관련 개선을 위한 기술기준(안)을 제안하여 전문가들의 의견 수렴과 이를 분석한 결과, 비록 소수의 상반된 의견이 있었지만, 표준선 변경에 따른 환산교통량 변화가 해상교통혼잡도에 미치는 영향은 그리 크지 않음을 알 수 있었다. 마지막으로 평가관련 개선을 위한 최종 기술기준(안) 및 앞으로 발전방향을 제시하여 해상교통 혼잡도 평가 발전을 위한 연구기반을 마련하고자 하였다.

In adjacent sea areas of Yeosu, there are many crossing traffics between eastbound and westbound vessels. Traffic congestion is increasing in sea area of east Sori island and near Yokji Island. In this research, we established TSS near Yeokmando Areas and new recommended route which connected to Seopdo west recommended route to reduce meeting traffic between eastbound vessels and westbound vessels.

In recent years, the marine traffic congestion has increased due to the expansion of vessel traffic volume in Korean coastal waterway. Heavy traffic could bring serious marine casualties which cause the loss of human lives, properties and marine pollution in coastal area. The prevention of marine accidents has been a major topic in marin society and various policies and countermeasures have been developed, applied to the industries. VTS(Vessel Traffic Services) is considered as one of effective method to promote marine safety but it needs relatively huge amount of budgets to build and also number of personnels for the operation. Thus prior to establishing the VTS. It should be surveyed the marine traffics, general conditions of waterway including geographical, meteorological characteristics and assessed to find the most reasonable area and places for the system. Therefore this paper aims to develop the method for this evaluation through the hierarchical evaluation structure model in connection with ISM(interpretive structural modeling) and AHP(analytic hierarchy process) methods. The model in this paper is applied to 4 coastal area in Korean waterway as candidates and found that the priority for the needs of VTS should be in order such as Yosu, Wando, Mokpo, Geoje coastal area.

In the present maritime traffic conditions of mokpo harbor, there exists 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 of the last 10 years, the fishery status, operation of traffic routes and navigational aids 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.

Accidents between ships occur frequently at the traffic congestion area. Once a maritime accidents occur, it is likely to end up with critical damaged accidents. This paper develop a simulator for assessing quantitative risk based on statical maritime traffic data and realtime traffic distribution. Ship's passage risk assessment simulator consist of import of division of passage data, traffic distribution analysis and passage risk assessment analysis. Maritime traffic data of WANDO waterway apply to simulator for calculation of quantitative risk rate of waterway.

A mariner feels the ship-handling difficulty when the vessel onboard passes through breakwater. Until now, there is no a layout design of breakwater to take into account the ship-handling difficulty for the mariner. 11Us paper reproduced this situation which ship-handling is difficult by using marine traffic flow simulation, and it applied to Environmental Stress Model as the assessment model which is a quantitative model for evaluating the difficulty of ship-handling arising from restriction in maneuvering water areas and arising from traffic congestion The results are as follows. (1) The layout change of breakwater has little influence for reduction of ship-handling difficulty in the areas of vessel traffic volume. (2) In the situation of same breakwater width, difference of ship speed has an effect on decrease of ship-handling difficulty. (3) Expansion of breakwater width decreases ship-handling difficulty quantitatively.
