A Study on the Ship Collision Avoidance Model considered Speed

From a point of view of suggesting the method to avoid ship`s collision, the speed of ships has to be considered sufficiently according to encounter angle of ships. But the new safe-guard ring of ship`s collision avoidance support model in the close quarters is established assuming that the ratio of own ship` speed to a target ship`s speed is less than about 1.7. Therefore in this paper, as doing a study concerned with the establishment of safe-guard ring reflected the encounter angle and the speed of ships, we will propose the new model of ship collision avoidance for safe maneuver of ship`s collision avoidance.
