We have packaged everything MnDOT released into a ZIP archive of PDFs (60 MB!).
These MnDOT documents clearly show that NASCO was set up as a "systems integrator" to oversee NAFTRACS, a project led by Lockheed Martin's subsidiary SAVI Networks to build a complete cargo monitoring and security regime, which would include placing up to 200 RFID truck monitoring stations along Interstates 35 and 94. The entire 'Network Infrastructure' would be overseen by "Total Transportation Domain Awareness Centers of Excellence," which seemingly would fuse all available sources of data, including weather, RFID, cargo tracking, intelligence and security cameras, into NORAD-like Command and Control centers. Effectively, as the docs say, this would 'militarize' cargo along I-35, by cloning SAVI's current military shipping container tracking system at their "Lighthouse" research lab, which already runs the Pentagon's Global Transportation Network.
