The GM(1,1) model was used to prognosticate all facts that influence road traffic safety, all facts were summarized to construct gray nonlinear regression model to anticipate the trend of road traffic accident. The result showed that the model had high prediction accuracy and reliable prediction result, and was suitable to predict road traffic accidents.%运用GM(1,1)模型对影响道路交通安全的各因素进行预测,然后将各影响因素综合起来构建灰色非线性回归模型,以预测道路交通事故发展趋势.结果表明,该模型的预测精度高,预测结果可靠,适用于道路交通事故预测.
