Benefits and Description
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This phase replaces outdated traffic signal controller and communications equipment.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.
