Cost
An adaptive signal control system for 8 intersections in Woodland Park, CO was implemented for $176,300.
From a Colorado DOT comparison of two adaptive signal control system deployments

Woodland Park,Colorado,United States
Summary Information
The Colorado Department of Transportation (CDOT) implemented two separate adaptive signal control systems, one in Region 2 and another in Region 4. This study was done as a comparison between two different technologies deployed in two different environments. In Region 2, the City of Greeley, in conjunction with CDOT installed InSync adaptive signals at 11 10th Street (US 34 Business) intersections. In Region 4, QuicTrac adaptive signals were installed at 8 intersections along US 24 in Woodland Park. These upgrades were made to meet the goals of the FHWA "Every Day Counts" initiative.
System Cost
With 8 adaptive signal controlled intersections, the cost of deploying active signal control on the US 24 Corridor was $176,300 ($22,000 per intersection) to construct, including minimal updates to existing infrastructure that were necessary to install the QuicTrac system. CDOT estimates that the additional upgrades that were undertaken in order to install this system cost almost $14,000. They estimate the "minimal project" cost for the "plug and play" installation of the QuicTrac system for 8 intersections to be $162,400 ($20,300 per intersection).
Necessary upgrades required for installation included local controller firmware at each intersection, QuicNet software and central operating system, and microwave vehicle presence sensors/detectors at each approach,
