摘要
货车轴重与货运量之间的线性关系十分明显。以2008年山东高速公路数据为例,建立货运量与轴重的关系模型并进行标定,对比拟合优度,找出最优模型。通过显著性检验,发现模型使用价值较高。将此模型应用于实例中,结果表明计算值与调查值之间的误差较小。
The linear relation between axle load of freight car and freight volume is very obvious. Taking the data of Shandong Expressway in 2008 for example,the relation model of axle load and freight volume is established and calibrated. With the comparison of goodness of fit,the optimal model is found out. According to significance test,it is discovered that the model has high practical value. Through the application of the model in practice,the result indicates that the error between calculated value and observations is very little.
