Common Traffic Counting Errors

Clear definitions, suitable footage, review checkpoints and documented assumptions reduce avoidable traffic-counting errors.

How the work is structured

A reliable traffic data study starts with a project-specific specification. The team defines locations, periods, observations, classifications and the intended data format before collection or analysis begins. This makes the result clearer to review and use in later decisions.

• Establish a clear project objective.
• Document the specification before data collection.
• Review results against the agreed deliverable.

Project considerations

Methodology must reflect local conditions, the available footage or field environment, authority requirements and the decisions the data is meant to support. Avoid applying a generic method where the study brief calls for a tailored approach.
