An investigation was conducted to predict ship trajectories and discern their navigational intent in intersecting waters. The study involved experiments utilizing AIS data near the Baoshan District, Shanghai, and the development of the RBFNN+KNN model. The data preprocessing steps encompassed: 1) cleaning abnormal trajectory points and routes; 2) employing the LOF algorithm to filter trajectories with significant outliers; 3) clustering ship trajectories. Two clusters, representing routes in the straight-ahead channel and the right-turn channel, were selected as the sample dataset. The RBF neural network was employed to forecast ships' trajectories in future time periods, and the KNN classification algorithm was integrated to determine the vessels' sailing intentions. The experimental outcomes demonstrated that the proposed method achieved 99.88% accuracy in navigational intent recognition for the training set and 99.18% for the test set. These results indicate the model's superior ability to predict ships' navigational intent.
