How to Make a Traffic Management Plan for Perth Projects
Planning roadworks, construction activities or infrastructure upgrades in Perth requires more than organising equipment and setting a work schedule. Project teams must also consider how vehicles, pedestrians and workers will move safely around the worksite. A well-prepared traffic management plan helps identify potential risks, organise traffic movements and reduce unnecessary disruption to surrounding roads.
For contractors and businesses across Western Australia, understanding how to make a traffic management plan is an important step towards preparing a worksite for safe and efficient operations. From the initial site assessment to the placement of traffic signs and the management of changing conditions, every stage needs careful consideration.
CRG Traffic Management supports projects with practical traffic management planning and traffic control services designed around individual site requirements.
What Is a Traffic Management Plan?
A traffic management plan (TMP) explains how traffic and pedestrian movements will be managed during work that affects a road, footpath, or surrounding access.
The plan identifies potential hazards, outlines suitable controls and explains how traffic will move through or around the affected area. Depending on the project, it may cover temporary lane closures, speed restrictions, detours, pedestrian access, construction vehicle movements and traffic control personnel.
In Western Australia, traffic management for roadworks must follow the applicable Main Roads WA requirements and relevant standards. The appropriate approval process depends on the road authority, the location and the nature of the proposed work.
Step 1: Assess the Project Location
The first step is to understand the site and the conditions surrounding it.
A site assessment helps identify existing traffic patterns, road layouts, nearby intersections and potential hazards. It also allows the project team to understand how the proposed work may affect drivers, pedestrians, cyclists and nearby properties.
During the assessment, consider:
Road width and available lane space
Traffic volumes and busy periods
Nearby intersections and driveways
Footpaths and pedestrian crossings
Public transport routes and stops
Construction vehicle access
Visibility and road conditions
Nearby businesses, schools and residential areas
For example, work beside a busy Perth arterial road may require a different approach from maintenance on a quiet suburban street. Understanding these differences early helps the team develop a plan that suits the actual location.
Step 2: Identify Potential Traffic Hazards
Once the site has been assessed, the next step is to identify hazards that could affect workers and road users.
These may include vehicles passing close to the work area, restricted visibility, reversing construction vehicles, pedestrian access changes, or queues forming near an intersection.
Each hazard should be assessed so that suitable control measures can be selected.
For example, if construction vehicles need to enter a busy worksite, the plan may need to address how they will access the site without creating unnecessary conflicts with moving traffic.
Similarly, if a footpath must be closed, the pedestrian route needs to be considered before work begins.
Identifying these issues early allows the project team to address them during planning rather than responding to avoidable problems once the site is active.
Step 3: Develop the Traffic Management Arrangements
After assessing the site and identifying risks, the next stage is to determine how traffic will be managed.
The arrangements should explain how vehicles will approach, pass and leave the work area. They should also consider how workers and pedestrians will move safely around the site.
Depending on the project, the plan may include:
Temporary traffic signs
Cones and barriers
Lane closures or restrictions
Detour routes
Traffic controllers
Pedestrian diversions
Construction vehicle entry and exit points
Temporary changes to access
The selected controls must suit the site conditions and applicable requirements. A generic arrangement may not be appropriate for every project, particularly where traffic volumes, road geometry or pedestrian activity create additional risks.
Step 4: Prepare a Traffic Control Plan
A traffic control plan supports the wider traffic management plan by showing how the proposed controls will be arranged at the worksite.
It may illustrate sign locations, traffic control devices, work areas, vehicle movements and pedestrian routes. The level of detail required depends on the nature and complexity of the project.
A clear plan helps traffic controllers, construction supervisors and other personnel understand how the arrangement should be implemented.
It also helps the team identify potential problems before equipment is installed.
Where a project requires a specific traffic guidance scheme, the relevant drawings and arrangements should be prepared and reviewed in accordance with the applicable requirements.
Step 5: Check Approvals and Compliance Requirements
Before work begins, confirm which road authority is responsible for the location and what approvals or notifications are required.
Projects affecting State roads may require approval or consent from Main Roads WA. Work on local government roads may require approval from the relevant council. Additional coordination may be necessary where traffic signals, public transport, utilities or other road users are affected.
Main Roads WA also sets requirements for traffic management company registration and individual accreditation in applicable circumstances.
Complex traffic management arrangements may require review and endorsement by an appropriately accredited Roadworks Traffic Manager.
Step 6: Organise Qualified Traffic Control Personnel
A well-prepared document needs to be implemented correctly on site.
Depending on the project requirements, trained and appropriately accredited traffic controllers may be needed to manage vehicle movements, support pedestrian access and communicate with the construction team.
Before work begins, the personnel involved should understand their responsibilities, the planned traffic arrangements and the procedures for communicating changes.
Site supervisors should also coordinate the timing of construction activities with traffic control operations.
Clear communication is particularly important when deliveries, heavy vehicles or equipment movements may affect public traffic.
Step 7: Consider Pedestrians and Local Access
Traffic planning should account for everyone who uses the surrounding area, not just motorists.
Roadworks can affect footpaths, shared paths, business entrances, residential driveways and public transport access. If these movements are overlooked, people may become confused or enter areas that are unsafe.
A suitable plan should identify how pedestrians will move around the work area and how access will be maintained where possible.
For businesses near a construction site, delivery access and customer entry may also need to be considered. Providing clear directions and practical alternative routes can help reduce inconvenience while work is underway.
Step 8: Review the Plan as Work Progresses
Traffic conditions can change as a project moves through different stages.
The work area may expand, equipment may need to be relocated, or traffic volumes may increase during peak periods. Weather and unexpected incidents can also affect conditions.
For this reason, traffic management should be monitored throughout the project.
If the actual conditions no longer match the approved or planned arrangement, the team should assess the situation and make changes through the appropriate review and approval process.
Keeping relevant records and ensuring the current traffic management documents are available on site also supports consistent implementation.
Common Mistakes to Avoid
When preparing a traffic management plan, avoid these common issues:
Leaving planning too late: Late preparation can create scheduling problems and leave insufficient time for necessary approvals.
Ignoring pedestrian access: Alternative routes should be considered before footpaths or crossings are affected.
Using unsuitable traffic controls: The arrangement must reflect the actual site conditions and applicable requirements.
Overlooking construction vehicles: Entry, exit, reversing and delivery movements need to be considered.
Failing to review changing conditions: The plan should remain suitable as the project develops.
Addressing these issues early can help improve coordination and reduce avoidable disruption.

Whether you are organising a short-term road repair or a larger construction activity, early planning can help identify risks, clarify access arrangements and prepare the site for implementation.
Final Thoughts
Making a traffic management plan for a Perth project involves assessing the location, identifying hazards, selecting suitable controls, checking approval requirements and coordinating the people responsible for implementing the arrangements.
A carefully prepared plan helps project teams manage traffic and pedestrian movements while reducing unnecessary disruption to the community. Reviewing the arrangements as work progresses is equally important because site conditions can change.
By involving an experienced traffic management provider early, contractors can approach their projects with clearer planning, better coordination, and a stronger focus on worksite safety.
