Vehicle Feature Evaluation Method Based on Hierarchical Clustering and Decision Tree

Abstract

A method for evaluating vehicle characteristics based on hierarchical clustering and decision trees. By establishing a motor vehicle management and control system, it can assist the transportation department in efficient and precise management; including determining the corresponding vehicle evaluation indicators based on the attributes of the vehicle itself and the behavior characteristics of the vehicle being driven. ; Obtain the evaluation index data of the vehicle to be evaluated; perform hierarchical clustering processing on the vehicle evaluation index data; classify and label according to the results of hierarchical clustering; establish a decision tree for training and then build based on the data marked after hierarchical clustering Vehicle risk assessment model: Based on the vehicle risk assessment model, the vehicle to be evaluated is evaluated for its risk level. The present invention uses a method combining hierarchical clustering and decision tree to build a vehicle risk level model, and through quantitative risk assessment, differentiates management of vehicles with different risks for traffic managers, improves the efficiency of road safety management, and reduces potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a method for evaluating vehicle characteristics based on hierarchical clustering and decision trees. Background technique [0002] For a long time, motor vehicles, as the main object of traffic management, have been under the key control of traffic managers. However, due to the sharp increase in the number of motor vehicles, the limited police resources of the traffic control department have been unable to carry out all-round strict control of them, resulting in various Traffic violations and chaos emerge in endlessly, bringing great hidden dangers to people's traffic safety. Contents of the invention [0003] A vehicle feature evaluation method based on hierarchical clustering and decision tree proposed by the present invention, combined with the actual needs of traffic police management, establishes a motor vehicle management and control system, which can assist the tr...
