Nashville, I-24 westbound, 30 November 2022, 06:00 to 10:00 CST, four mainline lanes over the instrumented miles. Mean speed from the I-24 MOTION trajectory instrument in 60 s × 100 m bins. Time runs left to right and position runs upward in the direction of travel, so every band sloping down to the right is a stop-and-go wave travelling backwards through the traffic. This is measured data, not a simulation.
