Lane Restriction Violation

Definition

A lane restriction violation occurs when a vehicle of a specified type (for example, a heavy-duty truck) is detected traveling in a lane where that vehicle type is prohibited (for example, the far-left lane of a highway).

Detecting this type of violation requires:

  • A camera monitoring the road segment.
  • CarTrack Pro enabled on the camera.
  • A Motion control area configured in CarTrack Pro settings (the red rectangle shown above).
  • Vehicle type recognition enabled in CarTrack Pro settings.
  • Optionally, an overview camera may also be used. No analytics configuration is required for the overview camera.

  1. Create a road object representing the road segment where lane restrictions are enforced.
  2. Bind cameras to the road object.
  3. Name the violation.
  4. Configure CarTrack Pro.
  5. Create the violation rule.
  6. Enable road object control.
  7. Review detected violations.

In CarTrack Pro settings:

  1. Set Track, Recognize to Track vehicles with a recognized plate.
