FOR IMMEDIATE RELEASE
Mayor Bowser Partners with Audi to Bring Smart Traffic Light Information Technology to the District
(WASHINGTON, DC) – Today, Mayor Muriel Bowser and Audi of America announced that more than 600 traffic light signals in the District of Columbia now support the “time-to-green” feature of Audi's Traffic Light Information technology.
The new data sharing program will provide real-time traffic signal information that has the potential to enhance the District’s traffic safety programs while reducing congestion and optimizing traffic flow.
“This initiative represents the kind of innovation that is critical for us to advance the traffic safety goals of Vision Zero,” said Mayor Bowser. “We look forward to building on this and similar partnerships as we continue to build a safer, stronger, and smarter DC.”
Under the partnership, the District will receive valuable information that could target specific areas for traffic safety improvements and increase the efficiency of the city’s traffic signal network.
“Audi continues to be an industry leader in connectivity and mobility solutions,” said Audi of America President Scott Keogh. “Not only do V2I applications and services like Traffic Light Information help to reduce driver stress, they are also essential infrastructure developments as we continue to move toward an automated future.”
Traffic Light Information (TLI), 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 United States.
TLI launched in 2016 with Las Vegas, Nevada. Since then, Audi, in partnership with Traffic Technology Services (TTS), has brought six other cities online to support the service including Dallas and Houston, Texas; San Francisco and Arcadia, California; Portland, Oregon, and Denver, Colorado. With the addition of Washington, DC, more than 1,600 traffic signals across the US support TLI.
When a car approaches a connected traffic light, it receives real-time signal information from the advanced traffic management system that monitors traffic lights via the onboard 4G LTE data connection. If 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 heads-up display (if equipped). This “time-to-green” information helps to reduce stress and allows the driver to relax knowing approximately how much time remains before light changes.
Future iterations of V2I technology could include integration into the vehicle’s start/stop function, optimized navigation routing, and predictive services such as speed recommendation designed to maximize the number of green lights a driver can make in sequence. All of these services have a goal to help reduce congestion and enhance mobility on crowded roadways.
The mission of the District Department of Transportation (DDOT) is to enhance the quality of life for District residents and visitors by ensuring that people, goods, and information move efficiently and safely with minimal adverse impact on residents and the environment.
