The first feature, called time to green, provides a display on Audi’s instrument panel that counts down the seconds until the red light turns green.
Other functions are being tested. Drivers could get more guidance on starting and stopping. Alternate routes could be calculated based on real-time traffic data. Or vehicle speeds could be suggested to maximize the number of green lights.
Beyond easing some driver frustration, the technology aims to improve traffic flow and create fuel efficiencies.
