车辆交通的混合ODE-PDE模型

A Mixed ODE-PDE Model for Vehicular Traffic

Rinaldo M. Colombo, Francesca Marcellini

摘要:

本文提出了一个由Lighthill-Whitham和Richards宏观模型与一阶微观跟随领导模型之间的胶合组成的交通流模型。该模型的基本分析性质进行了研究。存在性和唯一性的证明,以及基本估计的依赖性的解决方案,从初始数据。此外,数值积分显示了模型的一些定性特征,特别是使用不同模型的区域之间的信息传递。

英文摘要:

We present a traffic flow model consisting of a gluing between the Lighthill-Whitham and Richards macroscopic model with a first order microscopic follow the leader model. The basic analytical properties of this model are investigated. Existence and uniqueness are proved, as well as the basic estimates on the dependence of solutions from the initial data. Moreover, numerical integrations show some qualitative features of the model, in particular the transfer of information among regions where the different models are used.
