Purpose: The purpose of the paper is to present an innovative method of identification of navigational near-misses on the basis of a probabilistic domain, which can be used to assess the safety of navigation and to discover places potentially dangerous for navigation. Design/Methodology/Approach: Probabilistic domain construction based on a large amount of AIS data in a selected navigational area. Findings: In order to build and develop methods to assess the safety of navigation, ship probabilistic domains for three types of vessel encounter situations have been determined based on the AIS traffic monitoring data. Domains have been constructed for vessels moving in open waters with high traffic density in the Southern Baltic Sea. Practical Implications: One of the most important concepts concerning the safety of navigation at sea is the ship domain. The authors believe that data from vessel monitoring systems can be used to determine the limits of distances between passing vessels that are characteristic of specific water areas and fully take into account all factors influencing navigational decisions. Originality/Value: The novelty presented in the article is the method of navigational near-misses identification based on the probabilistic ship domain, which is universal for all vessels in a selected area.
