Approximately 6 billion gallons of fuel are wasted in the US each year as vehicles wait at stop lights or sit in dense traffic with engines idling, according to US Department of Energy estimates. In a real GRIDSMART system, they just send vehicle data to a controller, and it says, ‘I’ve got cars waiting, so it’s time to change the light.’
