摘　　要：在对收费型公路运营模式进行研究的基础上,利用交通规划软件建立了基于广义费用的交通流量分配模型即多方式多类型交通分配模型,通过对模型参数的科学标定和网络的合理设置,得到各类车型在特定网络上的流量分配、路段饱和率以及通行费用,并对此模型的应用效果进行分析,最终为区域高速公路网规划、路段交通量预测提供依据。In this paper, an traffic assignment mode named multi-modal multi-class model was built by using the transport planning software,which based on the generalized cost function. The model was coincident with the operating mode of domestic chargeable road. With the model, all manner of vehicles’ flow distribution、saturation factor of sections and costs can be obtained by means of demarcating the parameters and setting the networks. Then, the paper case researched on the applicable result, so as to provide consu...
