The Pennsylvania Department of Transportation (PennDOT) has created a new web application with a pre-populated database that consolidates information about 8,700 traffic signals located on state routes.
The one-stop electronic information warehouse will make it easier for PennDOT, municipalities and planning partners to oversee operations and improvements to the signals, a key factor in traffic flow around Pennsylvania.
Prior to the creation of the new web application, also known as the Traffic Signals Asset Management System (TSAMS), traffic signal information was scattered among paper records at a variety of locations, making it difficult to know the basis on which improvements could be developed and delivered.
PennDOT traffic operations staff worked with local partners to gather information on signal equipment, locations and connections to populate the database. It includes a GIS mapping interface and will have the ability to accept additional data over time on signals at intersections that are located on state routes and local roads. In addition to signals, other assets such as electronic signs, flashing warning devices, and school zone speed limit signs can also be added to the database.
The system is available to municipalities, planning partners and contractors or consultants working on their behalf.
The new database was supported through the Green Light-Go program, which was made possible by the state transportation funding plan, Act 89, and was created to help underwrite signal enhancements across the state.
