Characterization of Vessel Traffic Flow in Chengshanjiao Based on Origin-destination Data
A ship AIS(Automatic Identification System)trajectory clustering model based on origin-destination,OD)data was proposed.By clustering the OD data of the ship's AIS trajectory,the mod-el obtained the OD category combination of the start label and the end label.Thus,the ship trajecto-ries with similar behaviors were divided into the same cluster,the effective clustering of ship AIS traj-ectories was realized,and the noise trajectories were identified.On this basis,the characteristics of traffic flow such as ship navigation preference,OD position characteristics and ship group activity law in Chengshanjiao routing system waters were analyzed.
