| description | The invention belongs to a driving evaluation method, and provides a aggressive driving evaluation method and a related device for solving the technical problems that in an existing aggressive driving identification method, a subjective evaluation method lacks analysis of real driving data of a vehicle, and an objective evaluation method is difficult to accurately and comprehensively evaluate the aggressive driving degree. According to the method, dimension reduction processing is carried out through the PCA method, then clustering processing is carried out through the K-Means + + algorithm, compared with a K-Means algorithm for initializing the mass center, the strategy is more optimized, the clustering result is more accurate, and in addition, the convergence speed is higher and more accurate for large-scale vehicle track data. Finally, the aggressive driving index is calculated, the aggressive driving degree of a driver can be more accurately represented, and compared with the existing research that the ag |
