Audi Brings Traffic Light Tech To 600 Intersections In Washington D.C.

More than 600 intersections in the District of Columbia now feature “smart city” tech, allowing the traffic signal network to connect with Audi‘s Vehicle-to-Infrastructure (V2I) system.

Specifically, the intersections now support the “time-to-green” feature of Audi’s Traffic Light Information system, which is available on select 2017 and 2018 models.

“This initiative represents the kind of innovation that is critical for us to advance the traffic safety goals of Vision Zero,” stated Mayor Muriel Bowster. “We look forward to building on this, and similar partnerships, as we continue to build a safer, stronger, and smarter D.C.”

Meanwhile, Audi of America president Scott Keogh said that V2I technologies like Traffic Light Information “help reduce driver stress” and are also essential developments within the industry.

As an Audi connect PRIME feature, Time-to-Green works by receiving real-time signals from traffic management systems that monitor traffic lights via the car’s on-board 4G LTE data connection. When the light is red, this TLI feature will tell the driver how much longer he or she will need to wait until the signal changes to green.

This can happen via the car’s instrument cluster, or even in the head-up display, if the model features one.

In the future, more advanced iterations of V2I technology could work together with the vehicle’s start/stop function, offer optimized navigation routing and more, with the goal of reducing congestion and enhancing mobility.

    Too bad with all the traffic congestion you’ll never be able to take advantage of this. And let’s not forget impatient and distracted drivers rushing to make the light or turning when in the wrong lane. Knowing how long until the light turns green is nice but pointless IMO.

    It would be better if the cities used smart algorithms on the lights to let heavy traffic through, especially when there is no traffic in the traversing lanes. We have had the technology to do this for decades now, but somehow we don’t implement it, which literally costs us millions or billions per year in wasted time, not to mention fuel, pollution, and wear-and-tear. Here in LA, especially later when traffic subsides, it seems like you always wind up waiting at a red light with no cross traffic until one car comes. When that car gets there, then they can get a red light and you can finally go. It’s almost like the system is designed to generate gridlock.

    I dont get it? Why not just have a timer on the traffic light for everyone to see? We have those here so i dont need an audi to see how much time to zero

    In my country, most of the traffic lights come with the timer. that’s much useful than the crap invention that can only use on their brand.
