Audi of America in conjunction with Traffic Technology Services (TTS) will be launching the claimed first vehicle to infrastructure (V2I) technology called Traffic Light Information with some 2017 Q7, A4 and A4 Allroad models this autumn.
Traffic Light Information enables the car to communicate with the infrastructure in select cities and metropolitan areas across the US. The car receives real-time signal information from a traffic management system that monitors traffic lights. The link between vehicle and infrastructure is routed via the on-board LTE data connection and TTS servers.
While waiting at a connected traffic light, the driver information system in the instrument cluster, as well as the head-up-display (if equipped), indicates the time remaining until the signal changes to green.
"This feature is Audi's first step in vehicle-to-infrastructure integration," said Pom Malhotra, general manager, connected vehicles. "In the future we could envision this technology integrated into vehicle navigation, start/stop functionality and it could even be used to help improve traffic flow in municipalities. These improvements could lead to better overall efficiency and shorter commuting times."
Audi will begin to launch the new service as part of its Connect Prime services later this autumn in some 'smart' cities and metropolitan from next year. The feature is available on 2017 vehicles built after 1 June 2016.
