摘要:

“幻影拥堵”,即没有明显原因的交通堵塞,长期以来一直令交通科学家感到沮丧。在这里,我们得出了一个新的同源性之间的幻影堵塞和相关类的自持跨音速波,即爆炸。通过这种类比,我们描述的堵塞结构,有利的协议,从拥挤的高速公路的测量报告观察。补充的数值模拟提供了对堵塞发展的深入了解。我们的研究结果确定的条件可能会导致危险的车辆集中,从而在交通控制和道路设计提供指导。

英文摘要:

"Phantom jams," traffic blockages that arise without apparent cause, have long frustrated transportation scientists. Herein, we draw a novel homology between phantom jams and a related class of self-sustained transonic waves, namely detonations. Through this analogy, we describe the jam structure; favorable agreement with reported measurements from congested highways is observed. Complementary numerical simulations offer insights into the jams' development. Our results identify conditions likely to result in a dangerous concentration of vehicles and thereby lend guidance in traffic control and roadway design.
