Audi launches first vehicle-to-infrastructure tech in the US

Audi expects the technology to be rolled-out to cities across the US as it works with municipalities to prepare infrastructure for V2I connectivity

Audi plans to introduce the first vehicle-to-infrastructure (V2I) technology in production cars capable of connecting to the traffic signal network. This is the first step in connecting a vehicle to its surrounding infrastructure.


The roll-out in the US will begin this month in Las Vegas and will apply to the automaker’s A4, Q7 and A4 allroad models.


This so-called “time-to-green” feature will be the first feature to leverage the Audi Traffic Light Information service. When approaching a connected traffic light, Traffic Light Information displays the time remaining until the signal changes to green in the driver instrument cluster, as well as the head-up-display (if equipped). Providing the driver with this additional information helps reduce stress and allows the driver to relax knowing approximately how much time remains before the changing of the light, said Audi.


“The launch of this technology is another in a long list of firsts for Audi that have positioned us as the industry leader in connectivity solutions,” said Scott Keogh, president of Audi of America. “V2I applications and services like Traffic Light Information are essential components as we continue to move toward an autonomous future. We applaud the innovative approach of Las Vegas in working with us on V2I as well as on our various piloted driving demonstrations over the past years.”


In the future, Audi said it may be possible to integrate information from these advanced traffic management systems into vehicle start/stop features, navigation systems to optimise routing, and predictive services such as presenting the driver with a speed recommendation designed to maximize the number of green lights one can make in sequence.


All these services would be designed to either improve efficiency, drive time or traffic management.


Audi expects the technology to be rolled-out to additional cities across the US as it works with municipalities to prepare their infrastructure for V2I connectivity. Audi has partnered with Traffic Technology Services (TTS) to facilitate the transfer of traffic light data to Audi vehicles.


“The Regional Transportation Commission of Southern Nevada (RTC) is proud to be the first in the nation to connect our traffic signal network to vehicles through our collaboration with Audi,” added Tina Quigley, general manager, RTC.


“This vehicle-to-infrastructure technology will help reduce congestion and enhance mobility on our already crowded roadways. Beyond the glitz and glamour of the Las Vegas Strip, Southern Nevada continues to lead the way in transportation technology creating smart cities and communities for our residents and visitors.”
