The purpose of this project was to modernize traffic signal equipment and install transit signal priority along the corridor because the outdated existing traffic signal hardware limited the ability to manage traffic during peak periods and contributed to delays in transit.
The City also wanted to upgrade the inadequate traffic management due to the
lack of intelligent transportation systems and improve the obsolete and nonstandard Americans with Disabilities Act (ADA) compliant pedestrian facilities.
HOW WE HELPED
McCormick Taylor completed preliminary and final design for this project, as well as construction services. This project involved the completion of traffic signal construction plans, ITS plans, erosion and sedimentation plans, roadway plans, green infrastructure plans, and traffic control plans.
The signal upgrades included the installation of transit signal priority equipment at all intersections, design-build ADA upgrades to 25 of the 31 intersections, the installation of traffic controllers, pedestrian countdown signals, monitoring cameras, Bluetooth readers, upgraded pavement markings and crosswalks, and the installation of fiber optic cable.
Roadway design work included the design of two new pork-chop traffic islands at Knorr Street/Harbison Avenue and Solly Avenue/Large Street, as well as the reconstruction of one large existing traffic island at Castor Avenue. The Philadelphia Water Department also incorporated Green Street infrastructure upgrades at Unruh Avenue to be constructed simultaneously with the signal upgrades.
Because funding was provided through the Federal TIGER III grant system, this project required a fast-tracked schedule and coordination with PennDOT, the City of Philadelphia, and FHWA for review and approvals. Detailed coordination with each of the affected utility companies was necessary to obtain utility clearance. This coordination included providing traffic signal equipment details, modifications to the signal construction plans, and adding notes to the plan sheets. The Green Street infrastructure upgrades at Unruh Avenue required coordination with PennDOT, the Philadelphia Water Department Office of Watersheds, and the Pennsylvania Department of Environmental Protection.
