Closed Circuit Television (CCTV)

General Description:

Closed Circuit Television is a technology used to detect and monitor traffic or any other facility through the use of cameras placed in key locations.  Advanced systems use the cameras to detect traffic patterns and simultaneously adjust traffic signal timing plans to optimize an intersection’s capacity.  Simpler systems may be used to monitor locations for safety or other reasons.

Effects of Solution:

¨ Increase Passenger Throughput

¨ Increase Roadway Capacity

¨ Manage System Efficiency

¨ Reduce Local Demand

Closed Circuit Television is typically not a solution in itself.  CCTV is usually incorporated with additional technologies to be effective, such as being part of an RWIS system, or Traffic Management Center. 

Examples of Implementation:

See Additional Resources section for more information.

Cost/Financial Information:

Source: Source: United States Department of Transportation Intelligent Transportation Systems ITS Benefits, Costs and Lessons Learned Databases.  Available at http://www.benefitcost.its.dot.gov (Cost/financial information is estimated, and will vary based on size and scope of project, number of units, etc.)

	Capital Cost	Operating Cost
CCTV Camera (security)	$2.1-5K	$.1-.24K
CCTV Camera (traffic use)	$9-19K	$1.0-2.3K
CCTV Video Camera Tower	$4-12K
Camera integration	$2-2.5K

The first CCTV cost is associated with a unit used for indoor security purposes. 

Costs associated with the camera used for traffic include color video camera with pan, tilt, and zoom, and installation.

Tower costs on the low end are for a 35 ft. tower while the high cost is for 90 ft. tower.  These figures include the foundation, an aluminum pole, conduit, and labor.

Camera integration is for integration of a camera into an established system.
