Traffic Surveys and Their Role in Transport Planning

What Traffic Surveys Can Measure

The type of information collected depends on the purpose of the study and characteristics of the location. A survey can be designed around specific traffic movements or broader transport requirements.

Common information includes:

• Vehicle volumes
• Directional traffic movements
• Turning movements at junctions
• Vehicle classifications
• Traffic activity during peak periods
• Traffic activity during quieter periods
• Queue lengths
• Road link movements

Collecting the right information at the right location allows project teams to focus on the traffic conditions relevant to their assessment.

Why Traffic Data Matters

Traffic conditions are influenced by factors such as time of day, road layout, nearby developments, junction operation, and travel demand. A single observation may not provide enough information to understand these variations.

Traffic Count Surveys can collect repeated observations during defined periods, helping identify changes in traffic activity. The results can then be reviewed alongside other information when assessing a road or transport network.

For example, a development project may require information about traffic on surrounding roads. A transport consultant may also need junction movement data or vehicle classifications for a wider assessment.

Types of Traffic Surveys

Different survey methods can be used depending on the information required.

Junction Turning Counts

These surveys record vehicles travelling through junctions and can distinguish between movements such as left turns, right turns, and straight-ahead movements.

Link Counts

Link counts measure vehicle activity along a particular section of road. They can provide information about traffic volumes on specific routes.

Queue Surveys

Queue observations record the extent of vehicle queues at selected locations and can help identify changes in waiting conditions throughout the survey period.

Vehicle Classification Counts

Vehicles can be grouped into relevant categories where additional information about traffic composition is required.

Pedestrian and Cycle Counts

Where a project requires information about different modes, pedestrian and cycling activity can also be recorded to provide a broader picture of movement around a location.

The Traffic Survey Process

A structured process helps ensure that the collected information meets the requirements of the project.

Establishing the Requirements

The survey objectives, locations, observation periods, traffic movements, and required classifications are identified before data collection begins.

Selecting the Method

The collection approach can include manual observation, video recording, automated detection tools, sensors, and other technology-assisted methods, depending on the project.

Collecting the Data

Traffic activity is recorded consistently during the agreed observation period. The methodology can be adapted to the location and type of information being collected.

Validating the Results

Collected information is reviewed and checked before being processed. Validation helps identify inconsistencies and supports the preparation of usable datasets.

Presenting the Findings

The final information can be organised into tables, charts, and visual summaries within a client-ready report.

Applications in Transport and Development

Traffic information can support a variety of projects involving roads, developments, infrastructure, and transport planning.
Potential applications include:
• Transport assessments
• Development planning
• Traffic modelling
• Junction assessments
• Road network studies
• Infrastructure planning
• Traffic management reviews
• Access assessments
• Mobility research
• Before-and-after studies
The collected data can also be combined with parking, pedestrian, cycling, public transport, and queue information to provide additional context.

Benefits of Reliable Traffic Data

Good-quality traffic information can give project teams a factual basis for examining existing road conditions.

Location-specific information: Data is collected from the roads, junctions, or access points relevant to the project.

Time-based insight: Observations can show how traffic activity changes during selected periods.

Detailed movement information: Surveys can capture volumes, directions, turning movements, and classifications where required.

Supporting evidence: Results can contribute to wider transport assessments and planning studies.

Clear presentation: Tables, charts, and visual summaries make findings easier to review and interpret.

The usefulness of the results depends on appropriate survey design, consistent collection, and careful validation.
