Pittsburgh roads wired with ‘talking’ traffic signals

“Basically, everyone in the industry sees this technology as, yes, this is the right way to go, and this will increase safety more than we’ve ever seen in history,” said Stan Caldwell, executive director of Carnegie Mellon’s Traffic21 Institute and an adjunct associate professor of transportation and public policy.

PennDOT, in partnership with Carnegie Mellon University, has installed dedicated short-range communication radios at 35 intersections in Bloomfield and Marshall and will add 11 this year at intersections along McKnight Road in Ross and McCandless. The technology is endorsed by the federal Department of Transportation to transmit and receive connected car signals.
