How Long Should a Traffic Count Run?

Count duration is established from the project objective, expected traffic patterns, authority guidance and decisions the data will inform.

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.
