Accurately and effectively assessing the collision risk between ships is of great significance for the formulation of ship collision avoidance decisions. However, in different encounter situations, different evaluation indicators may play different roles, making it difficult to accurately and effectively calculate the risk of such ship collisions. Therefore, this article proposes a ship collision risk assessment model based on the D-S evidence theory. The model selects five factors: nearest encounter distance, nearest encounter time, relative distance between ships, relative orientation, and ship speed ratio to establish an evaluation index membership function. On this basis, the joint basic probability allocation method is used to evaluate the risk of ship collision. Three different ship collision scenarios were set up to validate the collision risk model of the ship, and the experimental results verified the effectiveness of the model.
