No more stopping for Audi drivers

Audi has announced a system that will allow drivers to adjust their speeds to make sure that when they arrive at the next traffic light, it will be green. The technology named ‘Green Light Optimized Speed Advisory’, or GLOSA, uses the position of the vehicle and vehicle-to-infrastructure communication to recommend a speed to a driver to create a ‘green wave’" and reduce the number of times they find the next light is red.

Audi previously launched GLOSA in 2016 in a handful of cities and regions. Now, the technology is being made in four new areas: Denver, White Plains, N.Y., and Orlando and Gainesville, Fla. Audi says the technology now covers 4,700 intersections in 13 metropolitan regions that also include Dallas, Houston, Kansas City, Las Vegas, Los Angeles, Phoenix, Portland, San Francisco, and Washington, D.C., along with Northern Virginia.

The system operates via the Audi Prime on-board communications suite and receives its information via the vehicle's on-board 4G LTE data connection. The Traffic Light Information system receives signals from the central traffic system in participating cities. When a traffic light connected to the system is red, the vehicle shows the length of time remaining until the signal changes to green, through a message in the instrument cluster in front of the driver, or in the head-up display if the vehicle has one. Audi says the added information ‘helps reduce stress by letting the driver know approximately how much time remains before the light changes.’

The technology was originally made available for the 2017 model year on the Audi A4 and Q7, expanded for the 2018 model year to the A5 and Q5, and for the 2019 model year on all Audi models except the A3, TT and R8.

It should be noted that some time ago, Jaguar Land Rover also announced a system to ensure that drivers of its cars arrived at traffic lights when they were green.
