Project Green Light, Google Research’s initiative to lower traffic emissions using AI, has expanded to 114 intersections throughout Boston.
This technology uses AI and Google Maps driving trends to model traffic patterns and recommend how to optimize existing traffic light plans. City engineers can implement the recommendations in as little as five minutes using existing infrastructure. By coordinating across several adjacent intersections to create waves of green lights, cities can improve traffic flow and reduce stop-and-go emissions.
Launched in 2023, Green Light is now live in 18 cities across four continents. Early numbers indicate the system has the potential to reduce traffic stops by up to 30% and reduce emissions at intersections by up to 10%.
The Google Research team is working to improve the lives of people around the world by bringing this technology to even more cities in the future.
