Audi networks with traffic lights in Düsseldorf

Audi Traffic Light Information: If stopping at a red light is unavoidable, a countdown displays the seconds remaining until the next green phase begins (function Time-to-Green). Drivers can relax, take their foot off the gas pedal and save fuel. A number of studies conclude that drivers move through cities more efficiently thanks to networked traffic lights. In a pilot project, Audi was able to reduce fuel consumption by 15 percent.
