Pittsburgh Pilot Program Shows Smart Signals Work
A group’s pilot program to cut air pollution in Pittsburgh, Pa., by developing “smart” traffic signals that communicate with one another is showing promise and should be expanded.
The technology was developed at Carnegie Mellon University and funded by the Henry L. Hillman Foundation, while the Heinz Endowments’ Breath Project and the Richard King Mellon Foundation have funded the pilot program.
The signals use artificial intelligence to communicate so the signals can adapt to changing traffic patterns in real-time to reduce traffic congestion.
