Audi first manufacturer to launch Green Light Optimized Speed Advisory (GLOSA) in U.S.GLOSA provides speed recommendations to minimize stops at red lights and helps reduce driver stressAudi Traffic Light Information (TLI) now available in 13 metro areas
In 2016, Audi, in collaboration with Traffic Technology Services (TTS), launched Traffic Light Information, an Audi connect PRIME feature that enables the car to communicate with the infrastructure in certain cities and metropolitan areas across the U.S. Today, more than 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, and Washington, D.C. and northern Virginia.
“VDOT’s collaboration with Audi, TTS, and other innovative companies leverages the Commonwealth’s data and vehicle-to-infrastructure communications, preparing us for more connected and automated vehicles on our roadways,” said Virginia Secretary of Transportation Shannon Valentine. “We are committed to improving safety, reducing congestion and exploring opportunities to partner with the private sector.”
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.
Future iterations of V2I technology could include integration with the vehicle’s start/stop function, optimized navigation routing, and other predictive services. All of these services are designed to help reduce congestion and enhance mobility on crowded roadways.
