Google Says AI-powered System Is Improving City
Traffic Flows
Google says an artificial intelligence (AI)-powered system
it created is helping improve traffic flow in major world
cities.
The system, called Project Green Light, is currently in use
in 12 cities.
The project aims to save fuel and lessen air
pollution, or emissions, from automobiles.
Google first announced the program in 2021, when it was
testing the system in four areas of Israel. Since then, the
company has kept expanding Project Green Light. Among
cities now taking part in the program are Bangalore,
Budapest, Jakarta, Manchester, Haifa, Hamburg, Rio de
Janeiro, and Seattle.
In an online announcement, Google’s Yossi Matias
explained the latest progress. He noted that the system is
being tested in areas with severe traffic issues. Generally,
this is at major crossings with heavy traffic and complex
traffic lights. These areas where vehicles start and stop are
known as intersections.
