PHOTO COURTESY OF AUDI - How Audi displays its data in Portland and other cities.Audi of America offers a vehicle-to-infrastructure (V2I) technology feature that works in the city of Portland. Traffic Light Information, available on some 2017 and 2018 Audi models, enables the car to communicate with the traffic signal infrastructure. The Portland Bureau of Transportation shares traffic signal status information with Audi and several other companies for similar services.

When a TLI-equipped vehicle approaches a connected traffic light, it receives real-time signal information from the traffic management system using the vehicle's on-board 4G/LTE data connection. When the light is red, the TLI feature displays the time remaining until the signal changes to green in the instrument cluster or in the vehicle's head-up display on the windshield. Audi believes "time-to-green" information helps reduce stress by letting the driver know approximately how much time remains before the light changes.

Future iterations of V2I technology could include integration within the vehicle's engine start/stop function, suggesting the optimum speed to encounter green lights, optimized navigation routing, and other predictive services. All of these services are designed to help reduce congestion and enhance mobility on crowded roadways.
