拥挤水域内船舶领域的探讨

Ship Domain in Congested Water Area

确定船舶领域是进行海上交通模拟以及研究船舶碰撞危险度的重要一环。在狭窄水道,特别是小船众多的拥挤水域,其船舶领域就不能按常规尺寸去确定,必须缩小.但船舶领域过小又会引起模拟结果不准,不能客观反映交通危险程度,为此本文提出了可变领域与目标预测的手段,对狭水道船舶交通进行模拟,取得较好的效果。

The ship domain is an important means in marine traffic simulation and research of ship collosion risks. As the normal ship domain cannot be applied to an narrow channol,espocially to an congested are a with many small crafts,the domain size should be reduced. However, if the domain is too small,the simulation will not be accurate enough and the extent of the traffic risk cannot be described objectively. This paper suggests that a variable domain and the target prediction be used to simulate the vessel traffic in the narrow channel.
