Audi Expands Traffic Light Information to 10 Cities

Aug 13, 2018

Audi of America has expanded its Traffic Light Information feature to two more U.S. cities: Phoenix and Kansas City.

In 2016, Audi, in collaboration with Traffic Technology Services (TTS), launched Traffic Light Information in Las Vegas. With the addition of Phoenix and Kansas City, 10 cities and more than 2,250 intersections across the U.S. use the service. Enabled cities include: Dallas; Houston; Palo Alto, California; Arcadia, California; Portland, Oregon; Denver; Las Vegas; and Washington, D.C.

Traffic Light Information, an Audi feature available on select 2017 and 2018 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 information helps reduce stress by letting the driver know approximately how much time remains before the light changes, according to Audi.

Future iterations of V2I technology, according to Audi, could include integration within the vehicle’s start/stop function, Green Light Optimized Speed Advisory (GLOSA), optimized navigation routing, and other predictive services. All of these services are designed to help reduce congestion and enhance mobility on crowded roadways.
