Audi’s new GLOSA software helps drivers avoid red lights

The German carmaker Audi is expanding its Traffic Light Information (TLI) system by adding a Green Light Optimised Speed Advisory (GLOSA) feature, which is designed to help drivers reach traffic lights as they turn green, according to a Wired report.

For two years now, Audi vehicles have provided drivers with a red light countdown via its TLI system, which provides drivers with information about traffic-light patterns and predicts how long it will be before the traffic light ahead turns green.


But now, Audi is expanding its TLI system with the addition GLOSA, a feature that combines traffic signal information, and the current position of the car, to calculate the ideal speed required to reach a green traffic light.

The system calculates its recommendation by considering the distance to the next light and the signal timing data, obtained via the vehicles onboard 4G LTE cellular data connections, according to the report.

The feature, which debuted on the A4 Sedan and Q7 SUV, is available on every 2019 Audi model, except for the A3 hatchback, TT coupe, and R8 supercar.

TLI and GLOSA – available on paid subscription basis – are currently available in 13 urban regions, including Dallas, Denver, Gainesville, Houston, Kansas City, Las Vegas, Los Angeles, New York (White Plains), Orlando, Phoenix, Portland, the San Francisco Bay Area (Palo Alto and Walnut Creek) and Washington, DC.

Future of driverless vehicles

Audi’s US boss, Mark Del Rosso, believes the green light technology is important to the future of driverless vehicles.

“Audi is committed to moving America in many ways, including through the development of industry-leading connectivity and mobility solutions,” Del Rosso was quoted as saying in a Yahoo report.

“Not only do vehicle-to-infrastructure technologies like GLOSA benefit drivers today, but they’re also the critical steps needed as we continue toward an automated future,” he added.
