Abstract

The invention relates to a construction method of a prediction model, and a vehicle accident prediction method and device. The construction method comprises the following steps: determining a training set only containing core features according to first data; the first data is driver behavior information, vehicle driving information, vehicle alarm information and environment information within a first set time in historical accident record information; training the clustering analysis model by adopting a training set only containing the core features; according to the prediction result of the vehicle accident, optimizing the clustering analysis model, and determining the optimized clustering analysis model as a prediction model; wherein the prediction result of the vehicle accident is obtained by predicting second data through the trained clustering analysis model. According to the method, various information before an accident occurs is comprehensively considered, and a clustering analysis model is optimized by adopting a vehicle accident prediction mode, so that the constructed prediction model is accurate and reliable, and potential accidents under various complex conditions can be effectively predicted.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a method for constructing a prediction model, a method and a device for predicting vehicle accidents. Background technique [0002] With the development of society, the transportation facilities are more and more developed, and people's travel needs are also increasing, but there are more and more traffic safety problems that follow. Traditional vehicle accident prevention measures include passive safety systems and active safety systems. However, both active safety systems and passive safety systems intervene late in accidents and cannot effectively predict accidents. With the continuous advancement of technology and the continuous increase of people's demand for vehicle functions, it is becoming more and more urgent to develop a preventive safety system that can predict accidents. [0003] In view of this, the present invention is proposed. Contents of the inventio...
