CTC Continues Its Work With Holly Springs, NC Developing Designs for Traffic Signal Control Fiber Connectivity

As an extension of its work in developing Holly Springs’ fiber business plan and in providing a full range of network implementation support, CTC is working jointly with the Town and the North Carolina Department of Transportation (NCDOT) to solve traffic communications problems by connecting signals, cameras, and traffic control infrastructure to the Town’s fiber network.

Fiber connectivity will facilitate dynamic control of traffic signal timing and reliable traffic signal status monitoring, ultimately reducing vehicular traffic congestion to the great benefit of the Town’s businesses and residents.

The network design will employ an innovative passive optical network (PON) solution to improve fiber efficiency and the Town’s ability to monitor and manage the network. Further, it will reflect the eventual transition of the ongoing operational and supervisory role of traffic signals and other ITS infrastructure from the NCDOT to Town personnel.

Over the course of this engagement, CTC will:

  • Prepare a system-level design, including applicable schematics and/or specifications identifying key system-level parameters impacting later design phases
  • Conduct a field verification and refinement of preliminary fiber routes, including site surveys of the approximately 16 traffic signal controller locations anticipated to be connected as part of this project
  • Determine all permits required for construction of the network, to include any right-of-way encroachment permits, utility easement modifications, and/or applicable environmental permitting required by the North Carolina Department of Environmental Quality (DEQ) or the U.S. Army Corps of Engineers (USACE), and initiate and manage the submissions of all required permits
  • Provide completed designs and permit application materials to the Town and/or NCDOT for review and approval, including “typicals”, GIS-based network maps, permit submissions/CAD engineering prints, material specifications, Bill of Materials (BOMs), splice matrices, and network logical (“stick”) schematics

CTC looks forward to continuing its work with the Town on another exciting and highly beneficial use of the Town’s investment in its fiber optic network.
