The invention provides a method and a device for measuring consistency of incoming traffic flow tracks. The method comprises the following steps: acquiring an aircraft track set in an airspace area of a target terminal; preprocessing trajectories in the aircraft trajectory set to obtain a plurality of to-be-processed approach trajectories; determining a course change time sequence of the approach trajectory to be processed; based on the course change time sequence of the to-be-processed approach trajectory, generating a simplified trajectory corresponding to the to-be-processed approach trajectory; clustering the simplified trajectory to obtain a multi-cluster approach traffic flow; and calculating the average track consistency corresponding to the approach traffic flow. The simplified trajectory of the approach trajectory to be processed is generated through the course change time sequence, the approach trajectory to be processed is simplified, the overall shape feature of the trajectory is reserved, and the simplified trajectory is clustered to calculate the average trajectory consistency corresponding to the approach traffic flow. The accuracy of measuring the consistency of the approach traffic flow tracks is improved, and the calculation efficiency is improved.
本发明提供了一种进场交通流轨迹一致性的测度方法及装置,该方法为:获取目标终端空域区域内的航空器轨迹集合;对航空器轨迹集合中的轨迹进行预处理以得到多条待处理进场轨迹;确定待处理进场轨迹的航向变化时间序列;基于待处理进场轨迹的航向变化时间序列,生成待处理进场轨迹对应的简化轨迹;对简化轨迹进行聚类以得到多簇进场交通流;计算进场交通流对应的平均轨迹一致性。通过航向变化时间序列生成待处理进场轨迹的简化轨迹,既简化了待处理进场轨迹又保留了轨迹整体形状特征,对简化轨迹进行聚类进而计算进场交通流对应的平均轨迹一致性,提高测度进场交通流轨迹一致性的准确性和提高计算效率。
