The ITS Deployment Tracking Surveys (DTS) were initiated to track progress toward a US Department of Transportation (DOT) goal (first set forth by the Secretary of Transportation in 1996) of achieving an integrated ITS infrastructure within the 75 largest metropolitan areas in ten years.  Following the goal period, the DTS continues to serve as a critical tool in measuring the extent of ITS deployment.   Selected questions are repeated so trends can be assessed, and new questions are added, based on input from USDOT Subject Matter Experts, to capture new ITS technologies and concepts.  Overall, the USDOT uses the results of the DTS to respond strategically to ITS deployment gaps and execute technical transfer activities that help states and local agencies plan and execute ITS deployments.
