Solving DC’s gridlock with smarter cars, intelligent traffic signals

A data-sharing partnership between the District Department of Transportation in Washington, D.C., and automobile manufacturer Audi of America has the potential to help the nation’s capital ease its notorious traffic congestion.

“The data that we are sharing with Audi in this case is our signal system information in real time,” said Soumya Dey, associate director for transportation operations and safety at DDOT. “What we want to get from Audi in return is the information about how long their vehicles are stopping at specific intersections.”

The Traffic Light Information vehicle-to-infrastructure (V2I) system, built in partnership with Traffic Technology Services, enables select 2017 and 2018 Audi models to communicate with the city’s traffic signal infrastructure.
