A Study on the Risk Evaluation in Two Dimensions at Sea with Even Risk Contour

등위험곡선을 이용한 해상의 2차원 위험도 평가에 관한 연구

In the decision of a collision avoidance action for navigators and intellignet ships, it is necessary to evaluate the degree of surrounding risks effectively. We propose the new risk evaluation technique in two dimensions using Even Risk Contour on the basis of the concept of contour line. In this paper, we introduce the algorithms ofERC and Approach Velocity(AV) and show their application for avoiding traffic collision at sea.
