Audi of America announced that more than 600 intersections in the District of Columbia support the “time-to-green” feature of Traffic Light Information.
In 2016, Audi launched Traffic Light Information in Las Vegas, Nevada. (Earlier post.) Audi, in collaboration with Traffic Technology Services (TTS), has brought the service to six other cities including areas of Dallas and Houston, Palo Alto and Arcadia, California, Portland, Oregon and Denver. With the addition of Washington, more than 1,600 intersections across the U.S. support Traffic Light Information.
Traffic Light Information, an Audi connect PRIME feature available on select 2017 and 2018 models, enables the car to communicate with the infrastructure in certain cities and metropolitan areas across the U.S.
When one of these select Audi models approaches a connected traffic light, it receives real-time signal information from the traffic management system that monitors traffic lights via the on-board 4G LTE data connection. When the light is red, the TLI feature will display the time remaining until the signal changes to green in the instrument cluster in front of the driver or in the head-up display (if equipped). This “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 start/stop function, Green Light Optimized Speed Advisory (GLOSA), optimized navigation routing and other predictive services. All of these services are designed to help reduce congestion and enhance mobility on crowded roadways.
