摘要: 首先介绍了交通平衡配流问题(TAP)的路段-节点模型,然后说明了该模型的平衡路径流量解一般是不唯一的。为了克服路段一节点模型这种应用上的缺陷,使交通规划人员在实际工作中能得到所需要的有关平衡路径流量的数据信息,利用极大嫡模型给出了确定平衡路径流量唯一解的方法。

Abstract: Firstly the link-node model of the traffic assignment problem (TAP) is introduced. Then we formulate that an equilibrium route flow solution to the link-node model is not unique in general. In order to hurdle this limitation and meet traffic engineers’ need for the data of the equilibrium route flow pattern, a method is given for finding unique route flows with the maximum entropy model.

Key words: link-node model, uniqueness, maximum entropy model
