Audi is expanding its Traffic Light Information system to now include speed recommendations to minimize stops. Audi is the first manufacturer to launch Green Light Optimized Speed Advisory (GLOSA) in the U.S.
GLOSA uses the position of the vehicle and traffic signal information to display a speed recommendation on the dash to reduce the number of stops at red lights. The distance to the stop, signal timing, and speed limit are all combined to produce an optimized speed.
Over 4,700 intersections in 13 U.S. metro areas support the technology.
Select 2017 and 2018 and newer models use an onboard 4G LTE connection to monitor live traffic signal information. When the light is red, the system will display a Time-to-Green indicator on the dash.
In future, this Vehicle-to-Infrastructure (V2I) technology could be used to optimize navigation routing, vehicle start/stop function, and other predictive services to reduce traffic congestion.
