What Is a Basic Traffic Management Plan?

Key Purpose of a Traffic Management Plan

A basic traffic management plan outlines how vehicles, pedestrians and workers will move safely around a work area. It provides practical guidance for controlling traffic movements and reducing risks where construction, maintenance or other activities may affect normal road use.

A basic traffic management plan gives workers and other road users clear information about temporary traffic arrangements. It can identify potential hazards, explain control measures and show how traffic will be managed while work is taking place. The level of detail required depends on the type, location and complexity of the project.

Main Components of the Plan

Work Area Details

The plan should clearly identify the location and nature of the proposed work. This may include the road, footpath, intersection, access point or surrounding area affected by the project.

Details can include:

• The location of the work site
• The type of work being undertaken
• Expected project duration
• Working hours
• Access requirements
• Potential impacts on surrounding traffic

Providing accurate site information helps everyone involved understand the conditions they are expected to manage.

Traffic Movement Arrangements

A traffic management plan should explain how vehicles will move through or around the work area. Depending on the project, traffic may need to be redirected, slowed or temporarily stopped.

Traffic arrangements may include lane changes, temporary traffic controls, detours and access restrictions. The plan should consider both normal traffic and unusual conditions that could occur during the project.

Pedestrian Management

Pedestrian movement is another important consideration. Construction activities can create hazards when footpaths are blocked, narrowed or redirected.

The plan should identify suitable pedestrian routes and explain how people will safely move past the work area. Temporary crossings, barriers, signs and controlled access may be required depending on the site conditions.

Assessing Risks Before Work Begins

Identifying Potential Hazards

Before developing traffic controls, the work site should be assessed for possible hazards. These may include moving vehicles, construction equipment, reduced visibility, narrow lanes, changing road conditions and interactions between workers and the public.

Identifying these risks early allows appropriate control measures to be considered before work begins.

Considering Road User Behaviour

Traffic management should account for how different road users are likely to respond to temporary changes. Drivers may encounter unfamiliar signs or altered lanes, while pedestrians may need to follow temporary pathways.

The plan should therefore provide clear and logical traffic arrangements that are easy for road users to understand.

Traffic Control Measures

Signs and Devices

Temporary signs and traffic control devices can help communicate changes to road users. Their positioning should provide enough time for drivers and pedestrians to recognise and respond to instructions.

Depending on the project, controls may include warning signs, regulatory signs, barriers, cones, delineation devices and other approved equipment.

Traffic Controllers

Traffic controllers may be required where traffic needs to be manually directed or where workers and road users interact closely. Their role can include managing vehicle movements, assisting with temporary traffic changes and helping maintain safe movement through the work area.

Appropriate training, equipment and communication are important when traffic controllers are used.

Planning for Construction Site Access

Vehicle Entry and Exit

Construction sites often require regular movement of trucks, machinery and worker vehicles. Site access should be considered carefully to prevent unnecessary conflicts with public traffic.

Entry and exit points should be planned so vehicles can move safely without creating avoidable congestion or hazards.

Deliveries and Heavy Vehicles

Large deliveries can have a significant impact on traffic conditions. The plan should consider delivery times, vehicle sizes, turning movements and available space within the site.

Where possible, deliveries should be organised to minimise disruption to surrounding road users.

When a Basic Plan May Be Appropriate

The level of traffic management required varies between projects. Smaller activities with limited impacts may require simpler arrangements, while major construction projects can require detailed traffic management planning supported by site specific assessments.

Factors such as road classification, traffic volume, work duration, pedestrian activity and proximity to intersections can influence the type of planning required.

A simple plan should still address the key risks associated with the activity. Keeping the document practical and relevant can make it easier for workers and traffic management personnel to follow.

Reviewing Traffic Arrangements

Monitoring Site Conditions

Traffic conditions can change once work begins. Unexpected congestion, changes in pedestrian movements, weather conditions or alterations to the construction program may affect the original arrangements.

Regular monitoring allows traffic controls to be reviewed when site conditions change.

Updating the Plan

If the scope or conditions of the project change, the traffic management arrangements may also need to be updated. Workers should be informed about significant changes before revised controls are implemented.

Keeping documentation current helps ensure that the traffic arrangements continue to reflect actual site conditions.

Frequently Asked Questions

What is the purpose of a traffic management plan?

Its purpose is to establish safe and practical arrangements for managing vehicles, pedestrians and workers around an area affected by temporary works.

Who prepares a traffic management plan?

The person responsible for preparing the plan depends on the project and applicable requirements. More complex projects may require suitably qualified traffic management professionals.

Does every construction project need the same traffic management plan?

No. Traffic management requirements vary according to factors such as the type of work, road environment, traffic conditions, pedestrian movements and potential risks.

Can a traffic management plan be changed during a project?

Yes. If site conditions, work activities or traffic arrangements change, the plan may need to be reviewed and updated to reflect the new conditions.
