Cities and states are turning to advanced technologies to improve traffic flow, increase safety for pedestrians and bicyclists and reduce collisions. Some examples include automated traffic enforcement for speeding or running red lights or traffic signals that give pedestrians a head start to cross the road. 

In late 2023, the Federal Highway Administration updated federal regulations governing traffic signs, signals and other roadway markings that included improvements for vulnerable road users.

North Carolina’s effort is the largest live statewide deployment of AI-based traffic signal software in the U.S., according to Flow Labs. “North Carolina didn’t just invest in a new tool — they embraced a new model for traffic operations,” Jatish Patel, CEO of Flow Labs, said in a statement.

Flow Labs has also worked with the Florida Department of Transportation on a project that combines data from the agency’s existing traffic-detection systems with connected vehicle data from TomTom, a location technology company. Merging these data sets in Flow Labs’ modeling system enables data-driven signal optimization, congestion mitigation and safety enhancements, the company says.
