Under the uniformly congested freeway and selecting appropriate flow density function, a freeway networkflowmodel is constructed.
考虑快速路一致拥挤的前提下，通过选取适当的流—密关系式，建立快速路网络流模型。

The networkflowmodel is an important kind of model of CIMS, and bottleneck analysis based on networkflowmodel is important to analysis and optimization of CIMS.
网络流模型是CIMS的一种重要模型，基于网络流模型的瓶颈分析对于CIMS的分析和优化具有重要意义。

On this basis, in order to minimize the two objectives of the transport costs to model, to convert it into a networkflowmodel with a stratified, with the minimum cost maximum flow algorithm.
