Each hour is compared with that sensor’s own free-flow speed rather than the speed limit, because some sensors sit on bends and slip roads that never reach 70 mph. Quiet hours carrying under 600 vehicles are left out, so overnight roadworks are not mistaken for congestion.

Plans can change on the night.
