Existence of traveling wave solutions in continuous OV models

Kota Ikeda, Toru Kan, Toshiyuki Ogawa

AI总结:

本研究针对交通流中宏观与微观模型关联多依赖数值验证、缺乏严格解析支撑的问题,通过分析拥堵对应的稀疏波与稠密波解的性质,证明了连续OV模型中宏观模型行波解的存在性并探究其特性,为两类模型的关联提供严格解析依据。

摘要:

在交通流领域,表征拥堵的自组织波传播现象已在宏观和微观模型中得到复现。作为宏观模型子类的流体动力学模型可从微观层面的跟车模型推导而来,已有研究探讨了两类模型间的关联,但多数验证依赖数值方法与形式化分析,因此需要解析方法来严格确保其有效性。本研究旨在基于对应稀疏波与稠密波拥堵的解的性质,探究宏观与微观模型的关联。具体而言,我们证明了宏观模型中行波解的存在性,并研究了其性质。

英文摘要:

In traffic flow, self-organized wave propagation, which characterizes congestion, has been reproduced in macroscopic and microscopic models. Hydrodynamic models, a subset of macroscopic models, can be derived from microscopic-level car-following models, and the relationship between these models has been investigated. However, most validations have relied on numerical methods and formal analyses; therefore, analytical approaches are necessary to rigorously ensure their validity. This study aims to investigate the relationship between macroscopic and microscopic models based on the properties of the solutions corresponding to congestion with sparse and dense waves. Specifically, we demonstrate the existence of traveling wave solutions in macroscopic models and investigate their properties.
