ORNL researchers use stop-light cameras to reduce fuel consumption of less-efficient vehicles via traffic management

Green Car Congress

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.’
