Lane restriction violations

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.

Lane restriction control workflow

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

Name the violation

On the Violation name settings page, click + to open the configuration window:

In CarTrack Pro settings:

1. Set Track, Recognize to Track vehicles with a recognized plate.
2. Enable Vehicle type and color recognition.




3. On the Traffic objects tab, click + → Motion control area and create an area covering the restricted lane.

Assign a descriptive name to the area, such as Trucks forbidden lane.

Formulate the rule

1. On the road object screen, under Camera list, click the camera label assigned to the monitoring camera (for example, Lane control).



2. Open the three-dot menu and click Violation rules.
3. On the next screen, locate the traffic object created earlier in CarTrack Pro settings (for example, Trucks forbidden lane) and click it.
