The count of maritime collisions increases yearly even with using assistant technologies like Automatic Radar Plotting Aid (ARPA) and Automatic Identification System (AIS). Several approaches for collision avoidance have been introduced in the maritime domain to improve maritime safety. In addition to purely physical aids to navigation (e.g. lighthouses and buoys), information and communication technology have evolved.This paper describes a literature review on the state of the art in maritime collision avoidance systems for checking their COLREGs-coverage in all situations mentioned in COLREGs such as conduct of vessels in sight of one another and in restricted visibility. Gaps are identified and solutions are proposed. A structured review is discussed in this paper to address each COLREGs rule/set of rules and to present approaches, methods and techniques considering the corresponding rule(s).On the basis of the review, the coverage of rules is shown. The rules not addressed by the state of the art collision avoidance approaches, i.e. parts C (Lights and Shapes) & D (Sound and Light Signals) rules, are analyzed and an automatic recognition concept of sound/light signals is proposed.
