Google Green Light

2023: System implementation in Abu Dhabi, Rio de Janeiro and Bali

On October 10, 2023, Google Research introduced the Green Light system, which allows you to dynamically control traffic lights depending on the current traffic situation. The platform is said to provide an opportunity to reduce the number of car stops by 30% and reduce emissions at intersections by 10%.

The Green Light system uses traffic data from the Google Maps mapping service. Special algorithms based on artificial intelligence analyze information about the location and movement of a huge number of Android devices. This information is used to simulate the traffic situation and calculate the optimal time for switching traffic lights from green to red and vice versa.

Google notes that city traffic engineers do not have access to comprehensive information to optimize traffic lights. Attempts to control traffic by using specialized sensors face high financial costs and the need for a time-consuming assessment of the situation. At the same time, Google has not only information about the movement of vehicles in real time, but also AI resources for processing this data.

The Green Light platform is said to provide the ability to model thousands of intersections at the same time. By optimizing the operation of traffic lights on neighboring streets, the system forms green light waves, allowing cars to move with fewer stops. As a result, fuel consumption is reduced, and therefore, emissions of harmful gases into the atmosphere are reduced.

According to Google, the integration of Green Light into the city's management system "takes only five minutes." The technology has already been rolled out in 12 cities - Abu Dhabi, Bali, Bengaluru, Budapest, Haifa, Hamburg, Hyderabad, Jakarta, Kolkata, Manchester, Rio de Janeiro and Seattle.^[1]
