인천항의 송도 신도시와 영종도 인천국제공항을 이어주는 제2연륙교 건설사업이 1999년 민간제안사업으로 정부에 제안되어 3차례에 걸쳐 실시된 선박의 통항 안전성에 관한 연구에도 불구하고 적정 교각폭이 결정되지 못하고 있다. 따라서 본 연구에서는 인천항의 장래 교통량의 측면과 최대선형의 선박 조종성 측면에서 소요 교각폭을 산정함을 목적으로 하고 있다. 연구결과, 제2연륙교 주경간 항로는 교통량 수용을 위하여 기본적으로 왕복항로 설계가 필요하며, 2020년 교통량 수용을 위한 소요 교각폭은 1,005m, 최대선형의 왕복통항을 위한 소요 교각폭은 990m로 산정되어 1,000m 교각폭이 장래 교통량 수용 및 최대선형의 안전한 왕복통항이 가능한 것으로 평가되었고, 700m 교각폭은 최대선형의 일방통항은 가능하나 최대선형과 일반 중·소형선박과의 왕복통항은 안전성이 확보되지 아니한 것으로 평가되었다.

In order to deal with the increase of container cargo traffic volume more effectively, the ministry of maritime affairs & fisheries has a long-term plan to develop Gaduk Island. According to the plan, the New Port will handle 4,600,00TEUs annually. The completion of the project will enable the port of Busan to perform as a hub port in the Asia Pacific era of the year 2000 with sufficient port facilities, and this will lead to a new era of oceanic Korea. With the advent of the Pacific Rim Era of the year 2000, Busan metropolis has set a strategic development plan to establish the area as the center of logistics in the noreast Asian region as well as to become the stronghold of economic activity in Korea's southeast region. To this end, industries that will open the doors to a marine era and a new industrial complex focused on logistics are planned in the West Busan area where Gimhae International Airport and the Busan New Port meet. This paper aims to find out the functional relation and complement between the Busan New Port Distri-Park handing container cargo traffic volume and the West Busan Logistics Pa가 handling an air cargo and railroad goods. Especially, paper aims to suggest the West Busan Logistics Park as the efficient management of the container cargo traffic volume due to the Development Plan of the Busan New Port.

When designing new marine traffic routes, it is desirable that the congestion due to traffic volume is evaluated by theoretical traffic capacity or by traffic simulation. Most of these techniques are applied to single server which is not considered channel width. Over-taking or paralle sailing of two or more vessels is allowalbe in Dover, Uraga, Gaduk-sudo, etc under their traffic capacity. In this paper, the Bumper Model is introduced to multiple severs in narrow channel and applied to Uraga Channel in Japan. The minimum width of Uraga Channel is 1, 400 m and its design traffic capacity is evaluated 19.26 ~ 19.52% of the basic traffic capacity. The traffic capacity on Gaduk Channel according to Busan New Port Development in 2011 will be estimated 3.59 % of maximum density and equal to 18.6% of that on Uraga Channel in 1992. The channel width Gaduk-sudo is designed 1, 600~2, 460 m and evaluated safe enough.
