河北省道路交通事故灰色預(yù)測(cè)模型的構(gòu)建與應(yīng)用
[Abstract]:The prediction and prevention of road traffic accidents is one of the main means to reduce traffic accidents and improve the level of traffic safety. It has gradually developed into a hot topic in the research of road traffic safety. Road traffic system is a dynamic and uncertain system, and the occurrence of traffic accidents is random. In view of the characteristic of "part information is known, part information is unknown" of road traffic system, the grey system theory is adopted to study the uncertain problem of "small sample, poor information" and the random object with "explicit extension and unclear connotation". Implement "less data modeling". This paper focuses on the study of the influence of macro factors of road traffic accidents on the number of deaths. The grey correlation analysis method is used to determine the main influencing factors and to establish a prediction index system. By constructing the grey prediction model MGM (1) based on grey relation analysis, N), weakens randomness by using the function of grey generating operator, analyzes the inherent relation of road traffic system, and excavates the latent law. Through the exchange between grey difference equation and grey differential equation, the continuous dynamic differential equation is established by using discrete data sequence, and the road traffic accident in Hebei Province is forecasted. Based on the statistics of road traffic accidents from 2000 to 2011 in Hebei Province, the death toll was predicted and the accuracy was tested. The empirical results show that the multi-factor grey prediction model based on grey correlation analysis is feasible and effective. Compared with the GM (1 / 1) prediction model, this method can predict the development situation of traffic accidents more reasonably, scientifically and accurately, and can provide management and decision-making basis for traffic related departments.
