交通网络设计问题的模型与算法的研究

Study on Traffic Network Design Model and Algorithm

交通网络设计问题是研究如何用定量的方法在已有交通网络上添加或扩容某些路段的问题。本文用基于均衡分配的双层最优化数学模型描述该问题 ,给出求解这类优化模型的算法 ,通过实例比较这些算法的性能 。

The traffic network design problems deals with how to add or improvement some links on an existing traffic network using quantitative analyssi method In this paper,the problem is described with bi?level optimum models on account of equilibrium assignment Algorithms for the optimum models are proposed,and these algorithms are compared by numerical examples At last,further study in this field is discussed
