Google's AI Traffic Light System Cuts Emissions and Stops in 12 Cities Worldwide

Google's Green Light project uses AI and Google Maps data to optimize traffic light timing in cities, reducing stops by 30% and emissions by 10%.

The project is active in 12 cities across the USA, Europe, and Asia, with plans to expand in 2024.

Traffic lights cause pollution, with intersection pollution 29x higher than open roads. Half comes from stop/start driving.

Project makes tweaks without new infrastructure, using existing traffic lights and patterns. Easier to implement.

Other initiatives aim to reduce emissions like fuel-efficient routing in Maps and EV shopping tools. Expanding sustainable transport.
