Your Audi Will Now Tell You How Fast To Go To Avoid Red Lights

Red lights are one of life’s minor inconveniences, but Audi of America is launching a new system that tells drivers how to avoid them.

Called Green Light Optimized Speed Advisory (GLOSA), the system uses vehicle-to-infrastructure (V2I) technology to communicate with traffic signals. The system then determines the car’s location and the timing of the traffic light. It will then calculate the optimum speed to travel to get a green light.

Unsurprisingly, the system also incorporates the speed limit into the calculation. As a result, drivers shouldn’t expect notifications to speed to get a green light.

The system works on select 2017 and newer Audi models and is an expansion of company’s Traffic Light Information system which displays the time remaining before a red light turns green. This means GLOSA works at more than 4,700 intersections in major metropolitan areas such as Dallas, Denver, Gainesville, Houston, Kansas City, Las Vegas, Los Angeles, New York City, Orlando, Portland, San Francisco and Washington, D.C as well as the greater northern Virginia region.

The system requires an Audi connect PRIME subscription which costs $199 for 6 months or $499 for 18 months on the 2019 A6, A7, A8 and Q8. That’s not chump change, but Audi hinted future updates could leverage V2I technology to provide optimized navigation routing and better fuel economy thanks to integration with a vehicle’s engine start/stop system.

GLOSA is a pretty cool idea and Audi says it was created to help drivers catch a so-called “green wave” of continuous green lights. This should help to make commutes less stressful as the automaker noted the average American spends nearly 300 hours every year stuck at red lights. That’s 12.5 days or more than seven 40-hour work weeks.

    “The system then determines the car’s location and the timing of the traffic light. It will then calculate the optimum speed to travel to get a green light.”

    im pretty sure it asume that youll be there first and without any other cars already waiting for the green light….. and this could be a problem.

    lmao this is great. “Please go 120MPH to get to next light.”

      Yeah, and I’m seriously pissed that my fingerprint takes only a millisecond to unlock my iPhone. This tech is so outdated. 😄

  • Nedlands

    So all other cars are going 40 and one is doing 25. Sounds llike a great idea. No one will be pissed off with that

    Okay, this is cool magic. If it works.

    I don’t know why everyone is so impressed. It’s just a sticker on the display that says, “Punch it.”

      Los Angeles says it has spend millions on traffic light sequencing. You’d never know it by driving around.

    I don’t get this point of traffic lights not having timers. Back here in Kolkata we have timers which tell when the lights are going to change. And I suppose a lot of other cities also have this. Features sick as traffic light timings should be provided by the authorities themselves instead of automakers providing it as an expensive feature.

    Kinda off-topic, but I really like the recent fonts used the instrument clusters by Audi, modern yet a bit late 80’s early 90’s style with the bold and simple type face. Reminds me of:

    Does it work when other drivers are in front of the Audi?
