Web12 Apr 2024 · Hip pain is a common complaint among runners and can be caused by a range of issues, including gluteal tendinopathy, bursitis and hip impingement. Shockwave therapy can be used to stimulate blood flow to the affected area, reduce inflammation, and promote healing. Focused shockwave therapy can reach this deeper region. Proximal hamstring … WebIn this test, the RSU generated a speed profile when it detected the first shockwave. Vehicles equipped with OBUs 1500 meters beyond the shockwave reduced their speed to 65 kph. As a result, gaps emerged in the traffic flow (visible as white zones in the plot). The first shockwave was successfully damped after only 30 seconds.

A second reason the bottleneck flow might drop is if the departure flow is affected by external sources, namely a bottleneck further downstream spilling backwards.
