Abstract

It may be reasonable to consider density per unit area over time rather than analyze traffic volume, which is simply the traffic volume per unit of time, in assessing the maritime traffic congestion of a certain area. This study contributes to the standardization of maritime traffic congestion assessment methods for the maritime traffic safety diagnosis institute while seeking a new method to minimize evaluation error due to converted traffic volume per ship tonnage level. To solve this problem, a method to evaluate maritime traffic congestion by comparing the area occupied by a vessel with the area of its route using vessel identification data from the Automatic Identification System (AIS) has been proposed. In this new model, it is possible to use actual data due to the development of information and communication technology, reducing conversion error while allowing for the evaluation of maritime traffic congestion by route.

어떤 해역의 해상교통혼잡도를 평가하는 데 있어서 단위 시간당 항행 척수인 교통량을 분석하는 것보다 어떤 시간 단면에 존재하는 단위 면적당의 밀집도 분석을 활용하는 것이 합리적일 수 있다. 본 연구에서는 해상교통안전진단 대행기관의 해상교통혼잡도 평가기법을 표준화하고, 선박톤급별 환산교통량 사용으로 인한 평가오차를 최소화하기 위하여 새로운 방안을 찾고자 한다. 이를 해결하기 위해 선박자동식별장치(Automatic Identification System, AIS)의 통항선박 데이터를 활용하여 항로구간면적 대비 식별된 개개의 통항선박이 갖고 있는 점용영역의 면적을 합산한 값과의 백분율을 해상교통혼잡도로 평가하는 방안을 제시하였다. 새로운 모형에서는 정보통신기술의 획기적인 발달로 인해 실제 데이터 사용이 가능하여 환산 데이터에 의한 오차발생을 줄일 수 있고, 항로구간별 해상교통혼잡도 평가도 가능하게 되었다.
