Abstract

The invention relates to a method for constructing a prediction model, a vehicle accident prediction method and a device. The construction method includes the following steps: according to the first data, determine a training set containing only core features; the first data is the driver behavior information, vehicle driving information, and vehicle alarm information within the first set time in the historical accident record information. Information and environmental information; the cluster analysis model is trained by using a training set that only contains core features; according to the prediction results of vehicle accidents, the cluster analysis model is optimized, and the optimized cluster analysis model is determined to be a prediction model; wherein, the The prediction result of the vehicle accident is obtained by predicting the second data with the trained cluster analysis model. This method comprehensively considers a variety of information before the accident, and optimizes the cluster analysis model by using the prediction method of vehicle accidents, so that the prediction model constructed is accurate and reliable, and can be effective for potential accidents in various complex situations predict.

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...
