Google said it intends to test the use of artificial intelligence (AI) to optimize traffic-signal timing in Rio de Janeiro, following a successful implementation in Israel.

The Israeli project slashed fuel use and traffic delays at four locations in Haifa and Beer-Sheva by 10% to 20%.

Rio's municipal traffic authority said Google's system should be launched within months, and had high hopes it could better control traffic signals.

Although simulations showed AI control of traffic signals could smooth traffic flow, the University of Pittsburgh's Aleksandar Stevanovic questioned whether a technology firm with zero traffic engineering expertise could realize such software.
