两类交通分配模型算法的关系及其应用

摘要

The relation between two types of traffic assignment model(four models) is discussed. It is discovered that capacity restraint traffic assignment's algorithm can be transformed into UE model's algorithm by adding one mold. The research is useful for programming software based on UE model in traffic planning. Furthermore, classifying problem of all-or-nothing traffic assignment model is analyzed. The results can be used in engineering.%针对两类(4个)交通分配模型及其关系，以及“全有全无”交通分配模型归类问题进行了研究，通过对比研究发现，仅需在目前常用的基于容限交通分配模型的算法中加入一个模块即可实现一种用户平衡模型的结果，为编写一类用户平衡的软件提供了捷径，对理论与实践也有一定的指导价值。
