GOOGLE WANTS TO USE AI FOR TRAFFIC LIGHT EFFICIENCY

-

Alphabet Inc’s Google cut fuel use and traffic delays by 10 per cent to 20 per cent at four locations in Israel by using artificial intelligen­ce to optimize signal lights and it next plans to test the software in Rio de Janeiro, the company said Wednesday. The early-phase research project is among new software initiative­s inside Google to combat climate change. Rio de Janeiro’s municipal traffic authority expressed high hopes for the AI to better time traffic signal changes. It told Reuters the system should be introduced within months. Aleksandar Stevanovic, an associate professor of civil and environmen­tal engineerin­g at University of Pittsburgh, said simulation­s show AI could smooth traffic flow, questioned whether a company without traffic engineerin­g expertise ultimately could bring such software to reality.
