The factors which affect the occurrence of traffic accidents are very complicated and of great uncertainty. There is some relationship between various influence factors of traffic accidents. Some influence factors dominate the development trends of traffic accidents. This paper uses the method of grey relational analysis to deal with the statistical data of traffic accidents in Beijing from 2002 to 2009. We select nine influence factors of traffic accidents for analysis, and find four influence factors, including number of trucks, total population, total length of highways, and number of large motor vehicles with higher grey relational grade, and set up the macro prediction model GM(1,N). Then the prediction result is undesirable and the probable reason is that the variation tendency of the influence factors is opposed to the variation tendency of traffic accidents.
