Transportation Operations & Safety:
Traffic Signals

Improved traffic signal maintenance, coordination, and technology upgrades have been identified as high priorities in the SPC region.  This is because traffic signal systems have been shown to provide some of the highest returns on investment of any transportation infrastructure projects.  In Pennsylvania, traffic signals are permitted by PennDOT, but are maintained and operated by local municipalities.  Therefore, regional coordination and multi-municipal cooperation are key to addressing this issue.  SPC, through its Transportation Operations & Safety Committee, has taken on a leading role in the development of a regional traffic signal program for Southwestern Pennsylvania.

This website serves as one tool in the management of traffic signal systems in Southwestern Pennsylvania by providing a clearinghouse for signal-related information and resources.
