摘要
建立基于灰色预测模型、非线性回归预测模型的交通事故次数的组合预测模型,对我国未来5年的交通事故次数进行了预测。从模型预测的结果来看,我国交通事故次数在未来几年将会保持下降的趋势。
Based on gray forecast and nonlinear regression a kind of combination forecasting model has been established to predict the amount of road accident in recent five years. From the result of combination forecasting model, the amount of road accident of our country will decline, and the trend of declination is obvious.
