Abstract
In order to efficiently mine the flight trajectory information in the terminal area and grasp the spatial distribution characteristics of the approaching traffic flow in the terminal area, this paper develops a flight trajectory data attribute correlation analysis model, and establishes a flight trajectory feature extraction model based on the data attribute correlation and improved k-means. Using the t-distributed stochastic neighbor embedding (t-SNE) method and density peaks clustering approach (DPCA), the prevailing traffic flow is then extracted. Finally, the real flight trajectory data in the terminal area are verified by analyzing the model parameters. The findings indicate that 788 flight trajectories are compressed to 100 trajectory points, divided into seven clusters, and seven prevailing traffic flows are extracted. Compared with the traditional flight trajectory clustering method, the accuracy of the method is improved by compressing the flight trajectory data scale and reducing the dimensionality. Simultaneously, the application of the DPCA method achieves a more detailed recognition of the flight trajectory.
