Phila. synchronizing traffic lights on 21 thoroughfares

To take the "stop" out of stop-and-go traffic, Philadelphia is spending about $90 million over three years to upgrade traffic signals and synchronize lights at more than 600 intersections along 21 major corridors in the city.
The first streets to get the upgrades are Oregon Avenue, 29th Street, Verree Road, Belmont Avenue, Bustleton Avenue, Chestnut Street, Walnut Street, and Woodland Avenue, said Stephen Buckley, deputy commissioner for transportation at the Streets Department.
Eventually, the city hopes to convert the lights at nearly all of its 3,000 signal-controlled intersections to digital signals that can be remotely controlled. Now, about 2,000 of the intersections are still controlled by old-fashioned electromechanical devices operated by timers on curbside poles.
The cost of replacing old signals with new, computerized signals can be more than $150,000 per intersection.
The city spent about $27 million last year to replace old signals with new ones on Market Street in West Philadelphia, on Passyunk Avenue between Broad Street and 63d Street, and on Lehigh Avenue between Broad and Richmond Streets.
But relatively simple timing adjustments to existing signals can make significant changes in traffic flow.
"If you can reduce crosstown driving by three or four minutes, that's helpful for everyone," Buckley said Thursday.
The city hadn't had a program to recalibrate the timers since the 1980s because of a lack of money and personnel, Buckley said.
The three-year plan for about $90 million will use primarily state and federal funds, he said.
