摘　　要：文中提出一种面向桥区水域的船舶非安全行为识别模型.通过分析桥区水域AIS数据,得出桥区船舶轨迹的行为特征,并将非安全行为分为追越与偏离两种.基于拟合的船舶领域建立船舶追越行为识别模型,结合改进的Hausdorff方法对桥区过桥轨迹进行聚类获得相应典型轨迹建立偏离行为识别模型.实验以武汉长江大桥桥区水域为例.证明桥区水域非安全航行行为识别模型可有效识别过桥船舶的追越、位置偏离、航速偏离等非安全行为.A ship unsafe behavior identification model for bridge area waters was proposed.By analyzing the AIS data in the waters of the bridge area,the behavior characteristics of the ship trajectory in the bridge area were obtained,and the unsafe behaviors were divided into overtaking and deviation.Based on the fitted ship domain,the identification model of ship overtaking behavior was established,and the corresponding typical trajectory was obtained by clustering the bridge crossing trajectory with the improved Hausdorff method,and the deviation behavior identification model was established.Taking the waters of Wuhan Yangtze River Bridge as an example,the experiment proves that the unsafe navigation behavior identification model in the waters of the bridge area can effectively identify unsafe behaviors such as overtaking,position deviation,speed deviation and so on.
