, through its Every Day Counts initiative, is working to accelerate the adoption of adaptive signal control technologies in the U.S. Its website states, "Real-time management of traffic systems is proven to work, yet these systems have been deployed on less than 1 percent of existing traffic signals. FHWA is now working to bring these technologies to the rest of the country."
