  • Now, Audi is updating its embedded traffic light-reading technology to help Audi's traffic light sensor gives you the power to catch as many.

    The German automaker’s traffic light information (or TLI, for short) system allows cars to “talk” to traffic lights, giving the driver a countdown to a green light. The system is a form of vehicle-to-infrastructure (V2I) communication. Both V2V and V2I are sometimes collectively.

    Audi can't help you avoid red lights entirely, but its Traffic Light Information system, which is available on all of Audi's models except A3 and TT.

    While it's a precursor for any integrated technology to come, Audi also believes it takes some of the anxiety out of sitting in traffic. The technology enables cars to display how long before a red light turns green; it will launch in the US this year. Sure enough, the light turns yellow, then red, and I come to a stop as the numbers tick off in reverse. TLI initially gave you enough information to know if you should slow down for the next light, and a countdown timer until the light turns green again.

    As I get closer to the intersection, a countdown starts on the dashboard. The light is currently green, but the new Audi I'm driving tells me it'll be seconds before I make it through the junction. Sure enough, the light turns yellow, then red, and I come to a stop as the numbers tick off in reverse. Once it hits four, the timer disappears, and within a few seconds the light turns green. It seems like a trivial feature, a timer telling you when a traffic signal is about to change.

    But in practice, it's quite useful. More important, it's currently available in Las Vegas, a baby step toward a future where cars and cities talk to one another to reduce gridlock. Audi is showing off its new Vehicle to Infrastructure framework V2I in Las Vegas, a town known more for gambling and debauchery than cutting-edge technology. The government agency actually oversees all of the city and surrounding area's transit infrastructure. From buses to traffic signals to new roads, it's all handled by a single entity, which allows it to move quickly to make changes to its system and partner with companies like Audi.

    The result is a car that knows when a light is about to turn green, thanks to the city sharing data with the vehicle through Audi's partner Traffic Technology Services TTS. At the server level the technology is a bit complex, with algorithms and data vetting. But as far as drivers are concerned, they don't have to do anything but drive. Here's how it works: When a car enters an area or city that supports V2I, it logs onto the infrastructure's cloud with a onetime-use token.

    As it's driving around, its GPS location and heading determine which traffic signal is coming up. The TTS serves up information about that light, and the car determines if you'll make it through the intersection in which case nothing happens or if you'll be caught by the red light.

    In that scenario, the countdown begins until the green light appears. During my lap of Vegas I found the countdown which appears on the dash and in the HUD quite helpful in determining how much time I had before I had to start driving again. In real life, a red light is an opportunity to switch a song or artist on a smartphone, check on your kids in the back seat or take a quick sip of coffee. The problem in all of those situations is you're not sure how much time you have to complete those tasks.

    With the countdown clock, you'd know. It's also slightly comforting to be reminded that the light will eventually turn green again. There have been plenty of times during my life as a driver when I've encountered a red light that didn't seem to acknowledge my car.

    I'd back up and pull forward, making sure the sensor detected my vehicle. This feature would tell me that, yes, the light will turn green again, and this is when it'll happen.

    And while Audi has been working on the technology behind this feature for years, it wouldn't be possible without the forward-thinking transit commission. RTC general manager Tina Quigley said the commission wants to set a precedent to help determine what automakers need and to figure out how it can budget these types of partnerships.

    After the presentation, she was headed to Washington, DC, to talk about what Las Vegas is doing and how it's accomplishing it. Meanwhile Audi is talking to other metropolitan areas about rolling out its V2I service beyond Las Vegas. But since most city's transportation systems are fragmented across multiple commissions, its unlikely they'll come online as quickly as Vegas did.
