최근접점 상대방위에 따른 선박충돌위험알고리즘 개발에 관한 연구 = A Study on the Degree of Collision Risk with Relative Bearing at CPA

다국어 초록 (Multilingual Abstract)

When VTSOs(Vessel Traffic Service Operators) determine the degree of collision risk of two vessels, they consider comprehensively information about each vessel’s course, speed, DCPA, TCPA and encountering situation. In this study, we proposed an algorithm in which two relative bearings as information about two vessel’s encountering situation are used to evaluate the degree of collision risk. In order to verify whether the proposed algorithm is reasonable, we set twenty encountering situations and conducted a survey of collision risk on fifty three VTSOs about those situations. By comparing the degrees of collision risk with the proposed algorithm to the results of the survey, we found that relative bearing at CPA is very important factor for VTSO to recognize the level of collision risk when two vessels are in encountering situation.

국문 초록 (Abstract)

일반적으로 VTSO(Vessel Traffic Service Operator)는 양 선박의 충돌위험 정도를 판단할 때, 선박들의 침로와 속력, DCPA(Distance to CPA)와 TCPA(Time to CPA) 그리고 양 선박의 조우상황 등을 종합적으로 고려한다. 이에 본 연구에서는 CPA에서의 양 선박 상대방위에 따른 충돌위험도 계산 알고리즘을 제안하고, 알고리즘의 타당성을 검증하기 위하여 다양한 조우상황별 충돌위험도 측정에 대한 VTSO의 설문조사를 실시하였다. 그 결과, 제안한 알고리즘에 의한 위험도 평가 결과와 VTSO의 설문결과 사이에 높은 상관관계가 있음이 확인되어 제안한 알고리즘의 유효성을 검증하였다.
