Last Major City to get Traffic Operations Center, Philadelphia starts bidding process

The center is the most important part of an ongoing scheme to upgrade all traffic signals in the city. Work has already started on the job of replacing 51 electromagnetic signals with digital ones, which will be networked via fiber optics to the new operations center. It is estimated the traffic signals project will cost $US10.6 million in total. The new set-up will help to ensure traffic flows more smoothly across the city.
