With this model, the elasticity factor of the rotation volumeofpassengertransportation will be developed.
运用此模型，对我国公路客运周转量的弹性系数进行了应用研究。

The larger the traffic volume on the specific circuit is, the higher the density ofpassenger traffic, freight transportation, the lower the average transportation cost is.
特定线路上的运输量越大，客运密度、货运密度越高，平均运输成本就越低。
