Summary Information

A study published in 2010 reported that the installation cost per intersection of Adaptive Traffic Control Systems (ATCS) varied significantly among ATCS users, ranging from $20,000 to more than $70,000 per intersection, with a median and mode of approximately $45,000 and $40,000, respectively. The study obtained the cost data from a survey of domestic and international agencies using ATCS. Responses were obtained from 34 of 42 agencies in North America (an 81% response rate). On average, the costs of installing an ATCS are approximately $65,000 per intersection.

The report highlighted that reported costs often include more than simply the installation of the adaptive components of the system. For example, reported costs may include replacement of the local intersection hardware, software, or even new communication infrastructure. (Survey responders could only report on the total costs per intersection of their deployments.)

The table below shows the distribution of the ATCS installation costs per intersection as reported in the survey results.
