Columbus Traffic Signal System Project Phase E

Benefits and Description

The existing Columbus Traffic Signal System (CTSS) was conceived and initiated in the 1970's and provided state-of-the-art control for its time.  The system allows for monitoring and operation of more than 1,000 signalized intersections, co-existence/operation of traffic surveillance cameras, and emergency pre-emption.  The City of Columbus is implementing infrastructure changes to migrate the CTSS to an open architecture that can serve central Ohio stakeholders with system connectivity and interoperability.  Future investments for the CTSS will continue to build upon previous investments as specified by the Columbus Traffic Signal System Assessment and Strategic Plan, November 2005.  CTSS Phase E is the fifth phase in a series of projects to migrate all Columbus traffic signals to a new central traffic control system.  This project includes approximately 220 signalized intersections including 14 Franklin County intersections.

This phase replaces outdated traffic signal controller and communications equipment.  Fiber optic cable communications will be used to communicate to the intersections.  Existing traffic surveillance cameras will be upgraded and new surveillance cameras are added to this phase.  This phase expands the ability for interagency data exchange for the Department of Public Service and Department of Technology as part of the Citywide Connectivity and TechColumbus goals with other agencies in the metropolitan Columbus region.  The design will support regional integration activities and the communications approach recommended by the Signal System Assessment and Strategic Plan.
