Abstract: | |
Ship collision risk is a fuzzy concept, which refers to the measurement of the possibility of collision between ships, and is a kind of early warning of possible danger in the future.The existing research on multi-ship collision risk is based on the evaluation method of two-ship collision risk, and the collision risk degree of target ship and each interfering ship is calculated separately, which is used to determine to avoid the ship. This method has a large gap with the actual situation and has certain defects. In open waters with fewer ships, it has certain accuracy, but it cannot accurately represent the degree of danger of the environment in which the target ship is located in busy waters. Lack of an assessment of the overall risk of the target vessel's perceived area. On the basis of the regional analysis of the ship's encounter, this paper analyzes the ship collision risk degree by combining the idea of velocity obstacles. The impact of multiple interfering vessels in the area on the target vessel was considered for the overall collision risk assessment. |
