São Paulo smart traffic lights

Overview

Researchers at the University of São Paulo created an adaptive traffic‑light system that uses image sensors and a real‑time algorithm to prioritize pedestrians, cutting wait times by about 71% in simulated tests at four city locations.

A few days later the municipal government announced a large‑scale rollout of the technology, installing intelligent signals at 1,677 intersections with a R$ 725.5 million investment. The expanded system is reported to increase road capacity by roughly 5.7% and reduce congestion by 12%. Additional tools, including a USP‑developed camera solution and a Google AI “Green Light” tool, are being piloted to further shorten pedestrian waits and lower vehicle stops. The city plans to reach 2,583 smart intersections, with many more projects in the pipeline.
