摘要/Abstract

摘要： 针对海上日趋复杂的情形,提高船舶交通服务系统(Vessel Traffic Service,VTS)的决策水平迫在眉睫。针对船舶航行轨迹多维度的特点以及对船舶轨迹预测的精确度和实时性的需求,提出了结合船舶自动识别系统(Automatic Identification System,AIS)数据和深度学习的船舶航行轨迹预测方法。构造基于AIS数据的航行轨迹特征,提出了循环神经网络-长短期记忆(Recurrent Neural Networks-Long Short-Term Memory,RNN-LSTM)模型,利用广州港内的船舶AIS数据对模型进行训练,并对未来船舶航行轨迹进行预测。实验结果表明,利用RNN-LSTM模型的预测方法具有精确度高、易实现的特点,并且与传统处理方法相比,其在处理序列数据方面更具优越性。

Abstract: It is imperative to raise the level of decision-making for vessel traffic service (VTS) system in the light of the increasingly complex maritime circumstances.Aiming at the multidimensional characteristics of the ship’s navigation trajectory and the demand for the accuracy and the real-time prediction of the ship’s trajectory,a prediction method combining ship trajectory automatic identification system (AIS) data and deep learning was proposed.The feature expression of vessel behavior based on AIS data was established and the recurrent neural network-long short term memory (RNN-LSTM) model was proposed.The model was trained by AIS data from the Guangzhou Harbor and used to predict vessel trajectory.The results show that the method can predict the characteristics of vessel trajectory timely with acceptable accuracy.Compared with the traditional processing method,it is more superior in processing time series data.

Key words: AIS, LSTM, RNN, Ship trajectory predict
