  • Effective plan and operation managements can be established in advance if the traffic volume of container ship will be forecasted in the trend for container port's cargo volume to increase. At the viewpoint for marine traffic the number of incoming and outgoing container ship can be presumed in the long run and organised rational plan to deal the demand of marine traffic on the basis. Therefore, the paper estimated the future traffic volume of incoming and outgoing container ship for Busan, Gwangyang, and Incheon port on a forecasting data basis of container volume suggested in the national ports base plan. The trends of volume per ship on container were estimated with ARIMA models and seasonal index was computed. Thus the traffic volume of container ship in the future was estimated computing with volume per ship in 2011,2015, and 2020 respectively.

  • The future cargo transportation and traffic volume on container in Gwangyang port was forecasted by using univariate time series models in this research. And the container ship traffic was produced. The constructed models all were most adapted to Winters' additive models with a trend and seasonal change. The cargo transportation on container in Gwangyang port was estimated each about 2,756 thousand TEU and 4,470 thousand TEU in 2011 and 2015 by increasing each 7.4%, 16.2% compared with 2007. The volume per ship on container was estimated each about 675TEU and 801TEU in 2011 and 2015 by increasing each 30.3%, 54.6% compared with 2007. Also, traffic volume on container incoming in Gwangyang Port was prospected each about 4,078ships and 5,921ships in 2011 and 2015.

  • Gamcheon harbor was developed as a multipurpose port to mix processing functions of exclusive piers for bulk cargo such as marine products, domestic cargoes. Since the container terminal was opened in 1997, maximum $40,000\sim50,000$ DWT containership have been incoming and outgoing. However, bemuse the breakwater entrance in Gamcheon harbor is narrow and the crossed vessels are ever-present at breakwater front, marine accident danger is high that grasping traffic characteristics is required in reply. Therefore marine traffic characteristics were analyzed for Gamcheon harbor and Gamcheon approaching waters, included the track and traffic volumes of peak hours period in inbound/outbound and front sea area of the harbor in present.

  • 무인 자가 운반 차량은 컨테이너 터미널 내 선박과 장치장 사이를 오가며 컨테이너를 운반하는 무인 장비로 컨테이너를 집고 내리는 하역 능력을 갖고 있다. 터미널에서 컨테이너의 처리량을 극대화하기 위해서는 컨테이너 운송 시간을 최소화하여야 하는데, 이를 위해서는 차량의 효율적인 주행 경로 설정이 필요하다. 최적의 주행경로를 설정하기 위한 방법으로 A*, ant colony optimization과 같은 탐색알고리즘을 이용해서 주행경로를 찾는 방안이 연구된바 있다. 하지만 교통 상황에 따라 최적의 주행 경로는 바뀌게 되는데 기존의 연구에서는 결정된 주행 경로에 대한 수정이 없기 때문에 이러한 변화를 반영하지 못하는 문제가 있었다. 이에 본 논문에서는 주행 중인 차량이 다른 차량의 간섭에 의하여 대기하는 경우 대기 시간을 이용하여 새로운 주행 경로를 탐색 하여 현재 교통 상황에 맞는 최적의 경로를 찾는 방안을 제안하였으며 실험을 통해 기존 방안보다 더 효율적임을 확인하였다.

  • Gamcheon Harbor was developed to cope with increased freight demand of Busan port and supplement function of the north port. Because container wharf is opened to 1997 as well as general wharf, present maximum 50,000DWT class containerships have been incoming and outgoing. However, In Gamcheon port, small size ships such as fishing boats, miscellaneous boats account for 50 percent of the traffic and a public marine products wholesale market that is building on the north wharf will open in 2008. Therefore, it needs to grasp future year traffic volume before establishing operation plan for port management. Also, analysis on crossing situation risk is required because the breakwater entrance in Gamcheon Harbor is narrow and the crossed passing of ship is ever-present at breakwater front. Thus the traffic volume in the future was presumed and quantitative analysis was achieved on crossing situation though simulations with the traffic volume.

  • Busan New Port manages the largest volume of traffic among Korean ports, and accounts for 68.5% of the total volume of the Busan port. Due to this increase in volume, ultra large container ships call at Busan New Port. When the additional south container terminal as well as ongoing construction project of the west container terminal are completed, various encounters may occur at the Busan New Port entrance, which may cause collision risk.s Thus, the purpose of this study was to provide a plan to improve the safety of vessel traffic, in the in/out bound fairway of Busan New Port. For this purpose, the status of arrivals and departures of vessels in Busan New Port, was examined through maritime traffic flow analysis. Additionally, risk factors and safety measures were identified, by AHP analysis with ship operators of the study area. Also, based on the derived safety measures, scenarios were set using the Environmental Stress model (ES model), and the traffic risk level of each safety measure was identified through simulation. As a result, it is expected that setting the no entry area for one-way traffic would have a significant effect on mitigating risks at the Busan New Port entrance. This study can serve as a basis for preparing safety measures, to improve the navigation of vessels using Busan New Port. If safety measures are prepared in the future, it is necessary to verify the safety by using the traffic volume and flow changes according to the newly-opened berths.

  • 부산신항은 지형적인 특성상 마산 방면에서 입출항하는 선박과 신항으로 입출항하는 선박이 서로 교차하는 경우가 빈번하고 대형 컨테이너선과 저속 예부선 등의 통항량이 많을 뿐만 아니라 년 중 안개일수도 많아 충돌사고 위험이 상존한다. 따라서 선박에 정보제공 정도만 하는 소극적 관제 보다는 선박의 이동에 개입하는 적극적인 관제가 사고 방지에 더욱 효과적이라 할 수 있다. 부산신항의 관제 자료 및 해양안전심판원의 재결사례 등을 통하여 충돌사고의 원인을 분석하는 과정에서 적극적 관제의 필요성을 확인할 수 있었다. 본고에서는 부산신항에서의 적극적 관제 사례와 문제점을 주로 법률적인 측면에서 살펴보고, 적극적 관제의 개선 방안을 도출하여 보았다.

  • The Busan New harbor will be opened by 2011, after which it is expected that the marine traffic volume around this area would Increase significantly and that very large ships such as 12,000 TEU container ships would come into the port. Therefore, it is necessary to build a new ships' routeing by considering these factors. In this paper, environmental circumstances, marine traffics, and the preceding studies have been reviewed and ships' routeing is proposed through experts' opinions and Delphi technique. For the purpose of validation, the proposed ships' routeings are reviewed by several guidelines on the ships' routeing and through simulation studies.
