Shockwave in traffic

Web8 Apr 2024 · A moving shockwave, consisting of light traffic upstream of the shockwave and heavy traffic downstream, is usually caused by changes of local road situations. The density discontinuity travels upstream and drivers caught in the shockwave experience transitions from free to congested traffic. Boundary control design in this article brings the ... WebBraking. Often, the cause is a chain reaction, triggered by someone hitting the brakes. If your brake lights illuminate on the motorway, even for a brief moment, it can cause the driver behind to also apply their brakes. This passes along the queue of traffic, with the brake action getting ever-so-slightly longer as it passes through each car.
