Autos are a major contributor to Greenhouse Gas (GHG) emissions, particularly carbon dioxide (CO2) emissions, and unnecessary acceleration and hard braking in response to changing traffic signals, while not a major source of emissions, adds to wasted fuel and increased emissions. Alerting drivers to traffic signal status may help drivers avoid hard braking at intersections, resulting in lower fuel consumption and reduced emissions. A study modeled the effects of advanced driving alert systems (ADAS) for alerting drivers in advance of a traffic signal change, thus encouraging drivers to release the throttle and allow the vehicle to slowly cruise to a stop.
