What Is a Roundabout Count?

A roundabout count records traffic entering, exiting and circulating through a roundabout, often by approach and vehicle class.

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.

• Define the scope before collection begins.
• Agree classifications, intervals and movement rules.
• Apply review checks before final delivery.

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.
