| 摘 要： | 在实测数据的基础上,对一级干线公路运行速度影响因素进行单因素分析,运用统计学方法揭示一级公路的85%位速度与限制速度、纵坡、地形、车道宽、路肩宽、大型车比例、路侧干扰程度、出入口密度等因素之间的关系。在此基础上,应用多元线性回归方法分别建立一级公路大、小型车的运行速度模型。

| Abstract: | Single factor analysis method was applied to analyze the operating speed factors of first-class highway based on factual data.The statistical methods were used to analyze the relationship between 85% speed of first-class highway and speed limit,slope,topography,lane width,shoulder width,the proportion of large vehicles,roadside,density of access,etc.Based on this,the multi-linear regressing models were established respectively for big and small car of first-class highway. |

| Keywords: | first-class highway operating speed model vehicle type |
