Columbus Traffic Signal System Project Phase F
Benefits and Description of Project:
The existing Columbus Traffic Signal System
(CTSS) was conceived and initiated in the 1970s to provide state-of-the-art
control for its time. The system allows for monitoring and operating 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 F is the sixth phase in a series of
projects to migrate all Columbus traffic signals to a new central traffic
control system. This project will upgrade traffic signal and communications
infrastructure at approximately 175 intersections citywide. The communications
network will be expanded at 50 intersections already connected to the CTSS
central system located at the Columbus Traffic Management Center, and 75
traffic signals will be added to the system.
In addition, the project will add roadside
unit equipment for connected vehicle operations at 50 intersections. Six
proposed fiber optic access communications node sites and 35 CCTV traffic flow
monitors will also be constructed as part of the project. This will be
accomplished by installing new fiber optic interconnect cable underground in
trenched and bored conduit, or aerially along proposed and existing utility
poles.
Phase F 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.
