Validate the speed measurement before the threshold

A defensible speed estimate needs suitable geometry, reliable timing and reference testing. Compare results with the agreed site rule only within the validated route and operating conditions.

Catalog workflow. Detector availability, scene suitability and event delivery must be verified for the proposed deployment. Camera observations supplement human review and established safety procedures.

The Process

How It Works

Apparent motion is not a physical speed reading Make speed review traceable to a measurement method.

01

Camera input

Capture a measured route segment with reliable timestamps.

02

Visual criteria

Validate estimates against an appropriate reference method.

03

Event review

Review candidate exceedances with sequence and uncertainty.

04

Operator response

Supervisor confirms the result under the site’s traffic process.

Frequently asked questions

Overspeed, Explained.

Reviews calibrated vehicle-speed estimates against an agreed site threshold.

Can speed be measured from any video?

No. Geometry and timing must support a validated method.

Can pixel movement be reported as km/h?

Not without valid calibration and timing.

Is this approved for legal enforcement?

No such approval is established; enforcement requires separate authority and evidence.

What invalidates calibration?

Camera movement, geometry changes or timing problems may require revalidation.
