Audi’s connected car technology helps drivers avoid red signals

LinkedIn +

Audi is the first manufacturer to employ vehicle-to-infrastructure (V2I) technology to include traffic light information that will enable drivers to avoid catching red traffic lights.

The launch of its Green Light Optimized Speed Advisory (GLOSA) system in the USA provides drivers with speed recommendations, which are displayed on the instrument panel, to minimize the amount of stops at red lights.

Available in certain 2017 and newer Audi models, the GLOSA system uses traffic signal information and the current position of a vehicle to display a speed recommendation intended to enable drivers to pass traffic lights during a green interval.

The distance to stop, the speed limit profile for the area, and the signal timing plans, are all used to calculate the speed recommendation, and will help aid the flow of traffic in 13 metropolitan areas across the USA.

“Audi is committed to moving America in many ways, including through the development of industry-leading connectivity and mobility solutions,” said Mark Del Rosso, president, Audi of America. “Not only do vehicle-to-infrastructure technologies like GLOSA benefit drivers today, they’re also the critical steps needed as we continue toward an automated future.”

Audi introduced its first innovative traffic technology in 2016 with the launch of Traffic Light Information (TLI) and its Time-to-Green feature, which is able to provide a countdown to when a connected traffic light will turn green. This gives drivers sat at stop signals an accurate time of when to prepare to move off or adjust their speed when approaching. It works by receiving real-time signal information from the traffic management system that monitors traffic lights via the onboard 4G LTE data connection.

Future iterations of V2I technology could include integration with a vehicle’s start/stop function, optimized navigation routing, and other predictive services. All of these services are designed to help reduce congestion and enhance mobility on crowded roadways.
