The Transportation Planning and Programming Division developed standard sheets for Traffic Data Collection site installations and repairs. These sheets should be considered for major pavement construction projects in truck corridors and construction or maintenance projects impacting existing traffic data collection sites.  

  • TDC-1 – Layouts and general notes for in-road sensors and loops for Weigh-In-Motion (WIM)
  • TDC-2 – Layouts and general notes for in-road sensors and loops for Vehicle Classification (VC)
  • TDC-3 – Traffic Data Collection specific loop details to supplement standard sheet LD(1)
