Assess vehicle speed with calibrated evidence

Camera perspective, frame timing and ground geometry determine whether a speed estimate is meaningful. Validate the setup against a suitable reference before interpreting values, and do not present unverified estimates as enforcement-grade measurements.

Catalog workflow. Confirm detector availability, permitted use and event delivery for the proposed deployment. Website examples are illustrative.

The Process

How It Works

Image motion alone is not a physical speed Review speed-related patterns with known limits.

Prepare the view

Survey the route geometry and camera stability.

Assess the observation

Validate speed estimates against an appropriate reference.

Review the evidence

Review values with source sequence and uncertainty.

Choose a response

Use confirmed findings within the approved traffic-review process.

Observation	Vehicle displacement over a measured time interval.	A vehicle’s successive visible positions.
Event criteria	A supported method converts validated image motion into a speed estimate.	A supported tracker links vehicle observations across frames.
Monitoring setup	Confirm ground scale, frame timing, vehicle paths and uncertainty.	Confirm vehicle classes, track gaps and monitored area.
What it cannot establish	Cannot guarantee exact speed or legal measurement validity without validation.	Cannot establish plate identity, exact speed or movement outside view.
Practical outcome	Help traffic teams assess route behavior with explicit measurement uncertainty.	Help operators review vehicle routes and interactions.
