本文提出了一个交通流模型,该模型由Lighthill-Whitham模型和理查兹宏观模型之间的一个胶合模型和一个跟随领导模型的一阶微观模型组成.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。版权所有© 2014约翰威利父子有限公司.
We present a traffic flow model consisting of a gluing between the Lighthill–Whitham and Richards macroscopic model with a first‐order microscopic following 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.
