Classified Traffic Count

Overview

A classified traffic count combines volume observations with a project-specific vehicle class scheme and reporting intervals.

What is the study?

A classified traffic count combines volume observations with a project-specific vehicle class scheme and reporting intervals.

Why it matters

A classified traffic count provides a clear, reviewable evidence base for freight planning, road design, traffic modelling decisions.

How it works

The approved brief defines locations, observation periods, movements, classifications, intervals and deliverables before collection or analysis begins.

Methodology

Methodology is agreed against the study objective, location type, relevant local requirements and required level of detail.

Data collection

Observation locations, directions, time periods and appropriate source material are confirmed before the agreed collection approach is applied.

Data processing

Recorded observations are organised into the agreed class, movement and interval structure for review and delivery.

Vehicle classification

Vehicle classes, active-travel requirements and direction definitions are set in the project specification.

Time intervals

Interval length, peak periods and reporting windows are agreed before work begins.

Typical project requirements

Useful briefs include locations, dates, duration, service scope, classifications, movement requirements and output format.

Deliverables

Deliverables can include structured tables, summaries and reporting formats agreed at project setup.

Quality control

Checks focus on completeness, consistency and adherence to the approved specification before delivery.

Country relevance

Terminology, classifications and output conventions are confirmed for the relevant country and project brief.

Privacy and security

Sensitive project information should be exchanged only through approved project workflows, not public forms.
