Individual collision risk assessment in ship navigation: A systematic literature review

The increasing attention to the improvement of navigational safety and autonomous navigation has led to the emergence of various tools and methods for collision risk assessment in ship navigation. An extensive systematic literature review has been carried out in this paper. It focuses on the parameters and methods of individual collision risk assessment providing input for navigational safety and autonomous navigation. We thoroughly assessed and analysed a number of papers on this topic, according to two dimensions: a model-based analysis, and a parametric clarification. Through this review, we seek to provide a greater understanding of the use and integration of parameters and methods in individual navigational collision risk assessments. Additionally, the information obtained through systematic literature review not only makes it possible to identify current circumstances, trends, and deficiencies, but also helps to focus future efforts. The results of the systematic literature review also indicate a literature gap regarding navigational collision risk assessment.
