Abstract

In this study, we analyzed AIS measured data for ten days by selecting the four main ports with many ships arriving in the national ports. The peak time congestion of the main ports, calculated by survey research, was about 3.8-5.7 times higher than the hourly average congestion. This is very different from the results of the advanced research, evaluating the marine traffic congestion of the Ulsan main port based on the existing Port-MIS statistical data, which showed a peak time congestion of about 1.7 times higher than the hourly average. This identifies the problem of distorting the traffic characteristics of the current passage. Therefore, in order to evaluate marine traffic congestion, it would be more appropriate to calculate it based on survey research, rather than Port-MIS statistical data.

본 연구는 우리나라 전국 무역항 중 입항 선박이 많은 주요 4개 항만을 선정하여 10일간의 AIS 실측 자료를 분석하였다. 실측 조사로 산출한 주요항만의 피크시간 혼잡도는 시간당 평균혼잡도 보다 약 3.8~5.7배 높게 나타났다. 이는 기존의 Port-MIS 통계자료로 울산항 본항의 해상교통혼잡도를 평가한 선행연구 사례에서 피크시간 혼잡도가 시간당 평균혼잡도 보다 약 1.7배 높은 것과는 많은 차이가 있어 현 항로의 교통특성을 왜곡하는 문제를 확인할 수 있다. 따라서 해상교통혼잡도를 평가할 때에는 Port-MIS 통계자료보다 실측조사를 기반으로 해상교통혼잡도를 산출하는 것이 타당하다고 본다.
