Audi announced today that its 2017 vehicles will be available with vehicle-to-infrastructure (V2I) communication technology that enables vehicles to inform drivers when lights will switch from red to green.
Audi of America will begin to roll out the traffic light information feature as part of its suite of Audi connect PRIME services later this fall in select smart cities and in metropolitan areas across the country through 2017. The company said traffic light information system is only the first step in V2I integration.
DOT For more than a decade, the DOT has been researching the potential benefits of connected vehicle technology, which allows vehicles to communicate with each other, roadway infrastructure, traffic management centers, and consumer mobile devices.
Using Wi-Fi connectivity, which Audi began offering in vehicles this year, a link between vehicle and infrastructure is routed via the on-board LTE data connection and then through servers owned by Beaverton, Ore.-based Traffic Technology Services Inc.
While waiting at a connected traffic light, the driver information system in the instrument cluster, as well as in heads-up-display equipped vehicles, indicates the time remaining until a signal changes to green.
The traffic light information system will be available on select 2017 Audi Q7, A4 and A4 allroad models with Audi Connect.
V2I is the wireless exchange of critical safety and operational data between vehicles and roadway infrastructure, intended primarily to avoid motor vehicle crashes. V2I has been a key research program of the Intelligent Transportation Systems Joint Program Office (ITS JPO) at the U.S. Department of Transportation (DOT).
For more than a decade, the DOT has been researching the potential benefits of connected vehicle technology, which allows vehicles to communicate with each other, roadway infrastructure, traffic management centers and consumer mobile devices.
In the future, V2I technology could be integrated with autonomous driving technology enabling vehicles to obey traffic signals without driver intervention.
In 2015, automakers began to introduce wireless broadcasts of vehicle operational data, which can be used for V2I and vehicle‐to‐vehicle communications (V2V). While helping to avoid vehicle crashes, V2V and V2I could also alleviate traffic congestion by controlling the flow of traffic more efficiently through intelligent transportation systems.
