Virtual Weigh Stations

Highly accurate license plate data capture at mainline speeds keeps commerce moving

When drivers are on the move, real-time, automated intelligence is required to accelerate throughput, support informed decision making, enforce compliance, and ensure safety is maximized.

The Perceptics Mainline LPR is a high resolution OCR imager designed to capture commercial vehicle license plate numbers with high accuracy. When you integrate the Perceptics Mainline LPR with our Mainline USDOT readers, you can check against multiple databases and screen larger populations of commercial vehicles on the mainline. With high speed, high performance functionality comes efficiency so that your officers can focus on inspecting only vehicles flagged with potential violations, allowing vehicles in compliance to continue moving.

Our systems are proven to help commercial vehicle enforcement operations:

  • Identify who is bypassing your weigh station
  • Access real-time, accurate data to ensure roadway safety for all travelers
  • Reduce weigh station congestion: only carriers with potential violations are flagged to exit to the weigh station
  • Integrate with weigh-in-motion (WIM) data
  • Reduce demand on weigh station facilities
  • Act as a force multiplier for your staff

License plate data can be captured by the Mainline LPR at speeds of up to and exceeding 120 mph. LPR data  can then be correlated with data from our Mainline DOT Readers to check Federal or State DOT databases for commercial vehicle safety violations and registration information.
