Mayor William Peduto Lauds City’s Cutting Edge Leadership on Real-time Traffic Signal Program

Mayor William Peduto Lauds City’s Cutting Edge Leadership on Real-time Traffic Signal Program

New traffic signal technology is coming to the city’s Baum-Centre corridor that extends Pittsburgh’s leadership in commuter, pedestrian and environmentally friendly traffic research, Mayor William Peduto announced today. The city is extending its cutting-edge system of real-time traffic signals that adapt instantly to shifting traffic conditions. A new $1.8 million pilot project will further test and strengthen the Pittsburgh system, providing fi
