Vehicle-to-infrastructure tech for A4, Q7, and Allroad debuts in Las Vegas.

Sitting in stop-and-go traffic could be a little less frustrating if you’re driving in Las Vegas with an Audi. It’s in the Nevada city that Audi is rolling out its Traffic Light Information technology, making it the first automaker to put that vehicle-to-infrastructure (V2I) feature into public use.

Traffic Light Information works on certain 2017 Audi A4, Q7, and Allroad models with a subscription to the Audi Connect Prime telematics system. It provides drivers with a message in the instrument cluster and/or head-up display indicating how long it will be until a red traffic light turns green. Audi says the feature will help reduce driver stress by letting drivers know how soon they’ll need to start driving again.

Going forward, Audi says it would like to integrate Traffic Light Information with the car’s navigation system, to avoid stop-and-go traffic, or with the engine stop-start function to save fuel.

“V2I applications and services like Traffic Light Information are essential components as we continue to move toward an autonomous future,” Audi of America president Scott Keogh said in a statement.

For now the system is only available in Las Vegas; Audi worked with the region’s transportation commission to upgrade traffic signals with V2I technology. Audi plans to expand the availability of Traffic Light Information to other U.S. cities over the coming months as those areas upgrade their signals, but hasn’t yet announced which cities are in the works. The automaker is working with connected-car company Traffic Technology Services to expand the reach of V2I.

In addition to buying the car, buyers must have the aforementioned Connect Prime subscription, which costs $199 for six months or $499 for an 18-month plan.
