Audi offers tons of technologies in its cars. Even after the cars were bought by the clients. The most recent one is called Green Light Optimized Speed Advisory (GLOSA) and is another industry first in vehicle-to-infrastructure (V2I) technologies from the brand. GLOSA can provide speed recommendations to Audi drivers of select 2017 and newer models that can assist drivers in catching the “green wave,” helping to reduce the number of stops at red lights.

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 profile 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.

Traffic Light Information, an Audi connect PRIME feature available on select 2017, 2018 and newer models, enables the car to communicate with the infrastructure in certain cities and metropolitan areas across the U.S.

When one of these select Audi models approaches a connected traffic light, it receives real-time signal information from the traffic management system that monitors traffic lights via the on-board 4G LTE data connection. When the light is red, the TLI feature will display the time remaining until the signal changes to green in the instrument cluster in front of the driver or in the head-up display (if equipped). This “time-to-green” information helps reduce stress by letting the driver know approximately how much time remains before the light changes.
