多目标交通分配模型

Multiobjectives Traffic Assignment Model

传统的交通分配模型都是对交通规划的某一个目标进行优化.并对获得的可选方案从性能、费用和影响等方面进行评价.交通系统的性能,影响和费用不但是可选方案的重要评价指标,而且是交通供给的主要研究内容.本文从交通供给的角度建立了一个多目标系统最优交通分配模型,将交通系统性能,费用作为目标,嵌入交通流格局的产生过程中,给出了求解模型的方法,本文最后进行了数例演算.

On the view of traffic supply, this paper establishes a multiobjective optimization traffic assignment model. Deals with the properties, effects and cost as objectives in the process of the generation of traffic flow pattern, the algorithm solving the model and a numerical example in the final has been given in this paper.
