초록

본 연구에서는 해상교통혼잡도에 영향을 미치는 요소인 선박점용영역크기, 선박의 속력, 항로폭에 대한 민감도 분석을 실시하였으며, 가장 민감한 요소로 선박점용영역을 도출하였다. 선박점용영역에 대해 일본, 덴마크 해협, 중국 상하이항에서의 점용영역에 대한 기존 연구사례를 조사하고, 우리나라 진해만 피항시의 해상교통관측조사를 통한 선박점용영역을 도출하여 비교 분석하였다. 민감도 분석결과, 선박속력 1노트 변화시 10 %, 항로폭 100미터 변화시 18 %, 점용영역 장직경 1L 변화시 34 %~43 %의 영향이 미치는 것으로 분석되었다. 그 결과, 현행 진단제도에서 사용하는 $8L{\times}3.2L$, $6L{\times}1.6L$은 일본의 $3.5L{\times}1.5L$, 중국 상하이항 $5.9L{\times}2.2L$, 덴마크 해협 $4L{\times}5B$ 및 진해만 피항시의 선박점용영역 $3L{\times}2L$과 큰 차이가 있음을 확인하였다.

This research concluded that the area is most sensitively affected by the maritime traffic congestion rather than other factors including the ship's speed and fairway width. We performed a literature review for the area used in Japan, Denmark, and Shanghai ports, and analyzed by comparing with the area in Jinhae, Korea through the observation survey of marine traffic. The result of sensitivity analysis concluded that the congestion is affected by amount of 10% by changing 1 knot of the ship's speed, 18% of 100m of the fairway width, and 34%~43% of 1L of ship's length. By applying the result into the current audit system using $8L{\times}3.2L$, $6L{\times}1.6L$, we found that there is big difference with $3.5L{\times}1.5L$ in Japan, $5.9L{\times}2.2L$ in Shanghai, $4L{\times}5B$ in Denmark, and $3L{\times}2L$ in Jinhae, Korea. For this reason, further studies should be carried out in near future to the area mostly affected by congestion.
