Audi of America has launched vehicle-to-infrastructure technology in the U.S. that's designed to provide drivers with speed recommendations to minimize stops at red lights and reduce driver frustration, the automaker has announced.
Known as Green Light Optimized Speed Advisory, the technology will be available on select 2017 and newer models. At the moment, the technology will work in 13 metro areas.
Drawing on traffic signal information and the current position of a vehicle, the technology displays a speed recommendation to the driver. The objective is to optimize mobility by allowing drivers to pass traffic lights during a green interval and reduce the number of stops at red lights.
Speed recommendations are calculated based on several factors including the distance to stop, the speed limit profile for the area, and the signal timing plans.
This is Audi's latest innovation in V2I technology. In 2016, in collaboration with Traffic Technology Services, Audi debuted Traffic Light Information that enables the connected Audi car to communicate with infrastructure. Audi cars equipped with TLI receive real-time information about traffic signals as they approach a red light. The feature alerts the driver with a "time-to-green" update — revealing the wait time, which helps reduce driver stress and anxiety.
Currently, over 4,700 intersections support both the "time-to-green" and GLOSA functionalities. Enabled metro areas include Dallas; Denver; Gainesville, Fla.; Houston; Kansas City, Kansas; Las Vegas; Los Angeles; New York City; Orlando, Fla; Phoenix; Portland, Ore.; San Francisco; Washington, D.C.; and northern Virginia.
