动态交通方式划分与系统最优配流模型

Model for modal split and assignment of dynamic traffic

由于现实交通流具有时变性,为了更好地缓解交通问题,交通配流规划者不仅要研究静态交通路径的选择,更要研究动态交通路径的选择和动态交通方式的选择。本文根据静态混合交通方式划分配流模型与动态系统最优一阶等价条件推广得到动态混合交通方式划分与配流模型,并证明了该模型一阶条件等价于瞬时的DSO条件和Logit方式分离函数。

In order to alleviate traffic problems,traffic planners should not only take account of the choice of the path but also consider the choice of dynamic transport modal.In this paper,a model for modal split and assignment of dynamic traffic are put forward.The model can satisfy the DSO conditions and the Logit function.
