We have broadened our initiative to lower traffic emissions using AI to over 100 intersections in Boston.

Project Green Light, an initiative by Google Research aimed at lowering traffic emissions through AI, has expanded to 114 intersections throughout Boston. This technology utilizes AI and Google Maps driving trends to model traffic patterns and recommend optimizations for existing traffic light plans. City engineers can implement these recommendations in as little as five minutes with current infrastructure. By coordinating multiple adjacent intersections to create waves of green lights, cities can enhance traffic flow and minimize stop-and-go emissions. 

Launched in 2023, Green Light is currently operational in 18 cities across four continents. Early data suggests that the system has the potential to decrease traffic stops by up to 30% and reduce emissions at intersections by up to 10%. The Google Research team is dedicated to improving the quality of life for people around the globe by expanding this technology to additional cities in the future.
