摘　　要：为定量评价渡船横越航道过程的碰撞风险,提出了基于船舶自动识别系统(Automatic Identification System,AIS)数据的渡船会遇识别和碰撞风险评价模型。首先根据船舶航行轨迹识别出会遇场景,然后利用模糊综合评价法构建船舶碰撞风险评价模型,实现船舶碰撞风险的实时量化,最后基于长江南京段汽渡船舶进行案例分析。结果表明渡船在横越过程中会遇态势复杂,平均碰撞风险一般随会遇船舶数量的增加而增大。提出的模型可以分析渡船横越过程中的碰撞风险变化趋势和不同会遇场景下的碰撞风险水平,为渡船碰撞风险感知与路径规划提供支撑。An AIS-based model for ship encounter situation identification and collision risk assessment is developed to monitor the ferry boats crossing main channel.The ship encounter scenarios are identified through examining the ship tracks.Fuzzy comprehensive evaluation is used to assess the collision risk.The process is accomplished in real time.The design is verified through processing the data set from the ferry Banqiao sailing in the Nanjing section of the Yangtze River.The experiment indicates that the situation of ship encountering can be rather complicated,especially when traffic is busy,which suggests the value of the research.
