This paper presents a novel method for extracting near-misses involving collision avoidance behaviour based on automatic identification system data. Previous methods for near-misses extraction primarily focused on detecting collision risks from ship-to-ship encounter scenarios. The proposed method introduces avoidance behaviour as an additional factor for extracting near-misses. It further analyzes the subject of avoidance behaviour through the avoidance intention, aiming to extract near-misses where one ship's avoidance behaviour is prompted by another ship within the same ship-to-ship scenario. The method consists of three primary stages: (1) Detection of encounter scenarios with collision risk using the velocity obstacle method; (2) Identification of encounter scenarios with maneuvering behaviour based on course data; (3) Recognition of near-misses involving avoidance behaviour by estimating avoidance intention. Finally, the effectiveness and innovativeness of the proposed method are validated through a comparative experiment, and the influence of various parameters is thoroughly analyzed in an applied experiment. •A method to identify and analyze near misses involving avoidance behaviour is proposed.•A velocity obstacle method is adopted to detect near misses involving potential collision risk.•Near misses involving avoidance behaviour are extracted by considering the heading changes.•Analysing the intentions behind avoidance behaviour in extracted near misses by relative bearing and relative velocity.
