Audi introducing V2I service in Europe.

Taking another step towards making driving in cities more relaxed and efficient, Audi is introducing the vehicle-to-infrastructure (V2I) service “Traffic Light Information” to Europe.

The automaker announced that from July Audi will network new models with the traffic lights in Ingolstadt/Germany; further European cities will follow from 2020 onwards.

“Traffic Light Information” will allow Audi drivers to see in the cockpit what speed is required to reach the next traffic light on green. If that is not possible within the permitted speed limit, there will be a countdown to the next green phase.

In function “Time-to-Green”, a countdown in the Audi virtual cockpit or head-up display counts the seconds to the next green phase if the driver will reach the lights on red. “Green Light Optimized Speed Advisory” (GLOSA) shows to the driver in the ideal speed for reaching the next traffic light on green.

Both Time-to-Green and GLOSA will be activated for the start of operation in Ingolstadt in selected Audi models. These include all Audi e-tron models and the A4, A6, A7, A8, Q3, Q7 and Q8 to be produced from mid-July (“model year 2020”). The prerequisite is the “Audi connect Navigation & Infotainment” package and the optional “camera-based traffic sign recognition”.

In the USA, Audi customers have already been using this service since late 2016 in cities including Denver, Houston, Las Vegas, Los Angeles, Portland, and Washington D.C.

On this project, Audi is working with Traffic Technology Services (TTS). TTS prepares the raw data from city traffic management centers and transmits them to the Audi servers. From here, the information reaches the car via a fast Internet connection.

The company believes that in the long term when cars send anonymized data to the city, urban traffic will benefit. Also in future, V2I technologies like Traffic Light Information will facilitate automated driving.
