移动交通拥堵的微观特征

Microscopic features of moving traffic jams

Boris S. Kerner, Sergey L. Klenov, Andreas Hiller, Hubert Rehborn

摘要:

提出了移动交通阻塞的经验和数值微观特征。基于单车数据分析,发现在宽移动堵塞内,即,在上游和下游堵塞前沿之间存在复杂的微观时空结构。这种堵塞结构由交通流中断的区域和与堵塞内的“移动空白”相关联的低速流动状态的交替组成。基于三相交通流理论的微观模型,揭示了大范围移动拥堵中移动空白出现的物理原因。在微观交通仿真的基础上,研究了运动阻塞前沿的结构。对与移动干扰传播相关的非线性效应进行了数值研究,并与经验结果进行了比较。

英文摘要:

Empirical and numerical microscopic features of moving traffic jams are presented. Based on a single vehicle data analysis, it is found that within wide moving jams, i.e., between the upstream and downstream jam fronts there is a complex microscopic spatiotemporal structure. This jam structure consists of alternations of regions in which traffic flow is interrupted and flow states of low speeds associated with "moving blanks" within the jam. Empirical features of the moving blanks are found. Based on microscopic models in the context of three-phase traffic theory, physical reasons for moving blanks emergence within wide moving jams are disclosed. Structure of moving jam fronts is studied based in microscopic traffic simulations. Non-linear effects associated with moving jam propagation are numerically investigated and compared with empirical results.
