ETO's headway coach, using secure public road-top lane lights, signals each driver their ETO vehicle headway (key to a fast smooth safe trip)... Pavement-embedded ETO signal lights spaced 10 metres (33 feet) along lane centrelines, guide each driver in real-time, to use best headway (speed and spacing) for fast safe steady efficient low-emissions traffic... Upstream of merge zones, ETO unifies speeds and gives vehicles extra headway time so at merge, headways settle gently back to 1.8 seconds.
