一种用于交通分配的替代出行路径生成模型

A Model for Generating Alternaltive Travel Path in Traffic Assignment

生成替代出行路径是选择出行路径和交通分配模型中对每对起迄点生成路径集的重要问题。本文提出了一种基于费用松弛系数的替代出行路径生成模型。文中讨论了这种模型的原理和结构,给出了一个算例。

Generating alternaltive travel path is an important problem which can be adapted in decision for selecting travel paths and in obtaining paths sets for whole OD pairs required in traffic assignment model. A model for generating alternaltive travel paths based on the cost-slack coefficient is proposed. In this paper, the principle and the structure of the model are discussed, an exaple is given.
