Audi Spreads Traffic Light Information Compatibility to 10 Cities


Audi's Traffic Light Information system is now available with corresponding streetlights in 10 U.S. cities.

The Traffic Light Information (TLI) system, an Audi Connect PRIME feature, was launched in 2016 in Las Vegas, NV. Audi partnered with Traffic Technology Services to create it. The way this feature works is simple--when a driver approaches a red light, the system counts down in seconds how long until it turns green.

More specifically, the onboard 4G LTE data connection enables the traffic management system to send real-time signal information to the system. This information is then relayed to the driver conveniently through the instrument cluster of select 2017 and 2018 Audi models. Or, if equipped, via the head-up display.

Scott Keogh, the president of Audi, states, "Audi continues to be an industry leader in connectivity and mobility solutions. Not only do V2I technologies like Traffic Light Information help to reduce driver stress, they are also essential infrastructure developments as we continue toward an automated future."


Not only does it lessen stress, but it also benefits surrounding drivers by helping reduce distraction. Nearly all drivers are guilty of checking their phone or engaging with the infotainment system while at a red light, which in turn, leads to them missing when the light turns green. TLI assists in the prevention of that and helps "reduce congestion and enhance mobility on crowded roadways."

Moving On

Now, thanks to the addition of Phoenix and areas of Kansas City, 10 cities are linked to this safety system, with more than 2,250 intersections being compatible.

The remaining eight cities include Dallas, Houston, Palo Alto, Arcadia, Portland, Denver, Washington D.C. and Las Vegas. Audi comments, "Future iterations of V2I technology could include integration within the vehicle's start/stop function, Green Light Optimized Speed Advisory (GLOSA), optimized navigation routing, and other predictive services."
