Lane Departure, Swerving & Potential Wrong Direction Events

Identify unsafe lane movement and potential wrong direction travel, alert drivers in the moment and give your team the context to respond.

EXPLORE EVENT TYPES

How Each Event Is Detected and Responded To

Lane departure
Detects when a vehicle crosses or remains outside a lane boundary for longer than the configured time. Uses road facing camera data to track lane position, time and distance outside the lane, while considering indicator status where available.
Swerving and unstable driving
The vehicle weaves within the lane or makes repeated steering corrections. Measures lateral movement and lane position to identify excessive corrections.
Potential wrong direction driving
Identifies when a vehicle appears to be travelling against the expected road direction, using vehicle heading and supported map data. Events are reviewed before being confirmed.
Related road alerts

Time out of Lane
How long the vehicle was over the lane boundary.
Maximum Distance from Lane
How far the vehicle moved beyond the lane boundary.
Return to Lane
How quickly the vehicle returned to its lane.
Indicator Status
Whether the indicator was active, where available.
Lane Marking Type
Solid and broken markings detected with their own severity.
Lateral Corrections
Steering corrections counted within the detection window.
Map Confidence
Direction confidence considered before a wrong direction event is raised.
Human Review
Wrong direction events require review before confirmation.
Detection Quality
Calibration, camera view, marking confidence, geometry and visibility.
Weather and Light
Conditions recorded on the event.
Five Seconds Either Side
Video from before and after the departure.
Vehicle Response
Lane position and speed before and after the alert.

Does an indicated lane change raise an event?
Indicator status is used where available, so a signalled lane change can be treated differently from an unsignalled departure. Where indicator data is unavailable, the event still records what happened for review.
How is swerving different from lane departure?
Lane departure means crossing the detected lane boundary. Swerving means repeated lateral movement or rapid steering corrections within the lane, making it an earlier indicator of unstable driving.
Why does a wrong direction event need human review?
Map data and road type are not infallible. Depots, private roads, contraflows and roadworks can produce headings that appear wrong when they are not. High severity is reserved for public roads with strong direction confidence, but confirmation always requires human review.
What if the lane markings are poor?
The event records lane marking confidence, road geometry, camera calibration, camera view and road visibility, so a reviewer can assess whether the detection is reliable enough to act on.
Can we set different rules for solid and broken lines?
Yes. Each can have its own minimum speed, minimum time out of lane, driver alert, manager notification and severity.
Is the driver alerted at the time?
Yes. A stay in your lane prompt is delivered through supported in cab devices. The system then looks for a positive change, such as returning to the lane or adjusting speed, with the before and after values recorded.
