在许多不同的驱动多粒子系统中已经观察到振荡流型。似乎可以合理地假设,反向流中的紧急振荡是由于或与效率(吞吐量)的增加有关。然而,在这篇文章中,我们将研究交叉的行人和车辆流作为一个例子,效率低下的紧急振荡。在车辆-行人耦合延误问题中,当行人过街与接近的汽车有一个小的时间间隔时,形成振荡的行人和车辆流,而当行人和车辆保持一定的超临界时间间隔时,两者都受益。也就是说,当行人的安全时间间隔增加时,行人的平均延误时间减少,车辆流量上升。这可以被解释为一个慢就是快的效果。解释了这种效应的基本机制。
Oscillatory flow patterns have been observed in many different driven many-particle systems. It seems reasonable to assume that the emergent oscillations in opposing flows are due to or related to an increased efficiency (throughput). In this contribution, however, we will study intersecting pedestrian and vehicle flows as an example for inefficient emergent oscillations. In the coupled vehicle–pedestrian delay problem, oscillating pedestrian and vehicle flows form when pedestrians cross the street with a small time gap to approaching cars, while both pedestrians and vehicles benefit, when they keep some overcritical time gap. That is, when the safety time gap of pedestrians is increased, the average delay time of pedestrians decreases and the vehicle flow goes up. This may be interpreted as a slower-is-faster effect. The underlying mechanism of this effect is explained.
