The invention relates to the technical field of Yangtze River digital navigation channels, and provides a ship route prediction method based on ship trajectory clustering so as to improve the accuracyof ship route prediction. The method comprises the following steps of obtaining the ship trajectory data of a target ship in a navigation channel, and pre-processing the missing values, abnormal values and data formats existing in the ship trajectory data; obtaining a high-quality historical route data set of the ship; clustering the historical routes of the predicted ship, extracting typical characteristic routes of the ship sailing in a control reach, matching the current track of the ship with the characteristic routes, predicting the route selected by the ship for passing through the control reach, and calculating the ship passing time based on the predicted route.

本发明涉及长江数字化航道技术领域，提供了一种基于船舶轨迹聚类的船舶航线预测方法，从而提高船舶航线预测的准确性，包括以下步骤：获取目标船舶在该航道的船舶轨迹数据，并对其中存在的缺失值、异常值及数据格式进行预处理，获得该船舶高质量的历史航线数据集；对该预测船舶的历史航线进行聚类，提取该船舶在控制河段内航行的典型特征航线，将该船舶当前轨迹与特征航线的进行匹配，预测该船舶通过控制河段选择的航线，并基于该预测航线计算船舶通行时间。
