Study on Automatic Collision Avoidance System and Method for Evaluating Collision Avoidance Manoeuvring Results

Abstract The authors have two goals that want to achieve. One is development of an automatic collision avoidance system for unmanned autonomous ships. And the other one is development of evaluation method of automatic collision avoidance manoeuvring results. In this paper, the outline of the developed automatic collision avoidance system and the result of the verification test on the actual ship navigating in congested waters are introduced. And also a discussion of the relationship between COLREGs and the desirable automatic collision avoidance system and methods for quantitatively assessing the desirable automatic collision avoidance system are introduced. In addition, quantitative comparison by the proposed evaluation system between the manoeuvring results of the automatic collision avoidance system and the veteran captain’s manoeuvring results are introduced.
