The city of Colorado Springs, Colorado spent about $5.6 million to replace in-pavement loops with video detection at 420 intersections.
Separate contracts for the video detection system were let for equipment and installation. The equipment bid included functional specifications and required a 2-year warranty and free upgrades. Installers were required to attend training conducted by the product vendor and city signal technicians. Fine-tuning of the cameras was performed by city crews. The cost per intersection varied based on the type of intersection (mast arm, span wire), number of cameras (1 to 8), and additional work (lighting). The average cost per intersection, $13,000, does not include city crew staff time, but does include the cost of a custom built video van, an additional bucket truck, and various test equipment. The relatively low cost per intersection is due in part to the large number of intersections involved in the project, keeping the equipment and installation bids separate, and using city crews to perform fine-tuning. Prior to contracting out for the video system, the city decided to evaluate a number of intersections. The cost for the 15 test intersections was $22,000 per intersection.
