Service summary
Classified traffic counts combine volume observation with a project-specific vehicle class scheme.
When it is used
Use them for freight, road design, traffic modelling and transport-planning inputs.
Methodology
Approve the class dictionary, count line or movement matrix, intervals and exception rules before observation.
Inputs and source requirements
Provide a location plan, dates, periods, defined observations, any classifications and required output files.
Movements and classifications
Movement, direction, lane and classification rules are agreed only where they are relevant to this study.
Time intervals
Set the reporting interval and any peak or operating windows before collection or processing.
Typical deliverables
Agreed data tables, location and methodology notes, defined assumptions and quality-review information.
Quality control
Check coverage, definitions, interval structure and delivery format against the approved brief.
Limitations
The result describes the defined observed scope and period; it should not be used to make claims beyond the available evidence.
Privacy and security
Sensitive files, video and identifiers are exchanged only through approved project workflows.
Frequently asked questions
Is a classified traffic count the same as vehicle classification?
They overlap: classified counts combine volume with a class scheme, while classification can also be added to movements or links.
Can a client define categories?
Yes, the approved dictionary should be fixed before observation.
