초록

본 연구는 시계제한으로 인한 선박 출항통제 해제 후 교통량이 폭주하는 것을 예방하기 위해 현 선박통제규정을 개선하고자 하였다. 평상시의 교통량과 출항통제 해제 후의 교통량를 분석하기 위해 AIS 데이터를 수집하였다. 출항통제 유무에 따른 피크시간 교통량의 차이를 확인하기 위하여 통계검정을 실시하였다. 연구결과 1만톤 미만 그룹에서는 t-test를 실시한 결과, 유의미한 교통량의 차이가 있는 것으로 나타났다. 1만톤 이상 그룹에서는 Mann-Whitney test 결과, 선박 통제 유무에 따른 교통량의 차이가 없는 것으로 나타났다. 출항통제 해제 후 1만톤 미만의 중소형 선박들은 평상시 보다 교통량이 142 % 증가하여 1만톤 이상 대형선박과 동시에 출항하게 됨에 따라 교통 폭주를 야기한 것으로 분석되었다. 이러한 교통량 폭주에 따른 선박 충돌사고 개연성을 미연에 방지하고자 현 규정을 길이 160 m 미만 또는 총톤수 1만톤 미만의 선박은 항해 가능하도록 개선할 것을 제언하였다.

The purpose of this study is to improve the current vessel departure control regulations to prevent traffic congestion after the lifting of vessel departure controls due to restricted visibility. AIS data was collected to analyze the traffic volume of normal traffic flow and after departure control. A statistical test was conducted to confirm the difference in traffic volume at peak hours according to whether or not departure control was used. The results of the t-test showed that there was a significant difference in traffic volume among groups of less than 10,000 tons in gross tonnage. However, the Mann-Whitney test showed no difference in traffic volume regardless of vessel control. Small and medium-sized vessels of less than 10,000 tons after departure control increased in traffic volume by 142% over normal traffic, and it was concluded that traffic congestion resulted as these small and medium-sized vessels were departing at the same time as large vessels of more than 10,000 tons. In order to prevent vessel collision accidents due to traffic congestion, it is suggested that the navigability of vessels less than 160 m or less than 10,000 tons should be improved.
