Pittsburgh’s Smart City proposal combines data, energy and transportation

A key element of the Pittsburgh proposal would be a ”smart spine system” on six streets that feed into the Golden Triangle: Penn, Liberty, Fifth, Forbes and Second avenues, and Bigelow Boulevard. The sources would include personal, public transit, government and freighthauling vehicles; street and traffic lights; and social media. That information would be used to monitor traffic and control traffic lights on those streets, a much larger version of the Surtrac signal control system developed by Carnegie Mellon University and used in East Liberty and Larimer. As part of the system, traffic lights would use sensors to identify transit and freight vehicles and allow them to move through the signals quicker. That eventually would be expanded throughout the city to all traffic signals
