  The dissipation of stop-and-go waves attracted recent attention as a traffic
management problem, which can be efficiently addressed by automated driving. As
part of the 100 automated vehicles experiment named MegaVanderTest, feedback
controls were used to induce strong dissipation via velocity smoothing. More
precisely, a single vehicle driving differently in one of the four lanes of
I-24 in the Nashville area was able to regularize the velocity profile by
reducing oscillations in time and velocity differences among vehicles.
Quantitative measures of this effect were possible due to the innovative I-24
MOTION system capable of monitoring the traffic conditions for all vehicles on
the roadway. This paper presents the control design, the technological aspects
involved in its deployment, and, finally, the results achieved by the
experiment.
