Green Light Optimized Speed Advisory can provide speed recommendations to Audi drivers of some 2017 and newer models that can assist drivers in catching the “green wave,” helping to reduce the number of stops at red lights.

The required 4G LTE coverage is not available in all areas. The system also requires compatible traffic infrastructure, which is also not available in all areas and it tracks your location.

GLOSA uses traffic signal information and the current position of a vehicle to display a speed recommendation intended to allow drivers to pass traffic lights during a green interval, in order to help reduce the number of stops at red lights. The distance to stop, the speed limit for the area, and the signal timing plans, are all used to calculate the speed recommendation displayed to the driver.

Survey data from the AAA Foundation for Traffic Safety shows that the average American driver spends nearly 300 hours a year behind the wheel, the equivalent to seven 40-hour weeks at the office. “Providing drivers with additional information, such as green light optimized speed advisories, can help reduce anxiety and improve a driver’s comfort during their time behind the wheel,” Audi claims.
