Traffic Impact Assessments in Melbourne, Sydney, Brisbane & Canberra. Quantum Traffic has wide-ranging experience and expertise in the preparation of Traffic Impact Assessments (TIA/TIAR).
What is a TIA?
In the course of a development application, you may be required by a local council or Department of Transport to submit a TIA report.
Most projects will have some degree of impact on traffic and parking. Effective urban planning requires that this be addressed through measures that eliminate or minimise any potential reductions in safety and efficiency.
By identifying critical factors, a Traffic Impact Assessment Report assists decision-makers in approving your project. This includes addressing issues such as traffic impacts on surrounding road networks, parking overflow impacts, and road safety impacts.
When is a TIA Needed?
Town Planning Applications
As part of applying for a planning permit, whether for new development or change in use, you’ll likely need to submit a TIA to support your case. Having this prepared professionally will ensure that your application has the best possible chance of being approved without unnecessary delays.
RFI Responses
In the process of having your planning permit approved, you may receive a Request For Information from the relevant council. If you haven’t already done so, in order to have your application progressed, planning councils may require a Traffic Impact Assessment in Sydney, Canberra, Brisbane or Melbourne.

FAQ
What is a Traffic Impact Assessment (TIA) and when is it required?
A TIA is a report that predicts the volume of vehicle traffic a new development will generate and assesses the capacity of the local road network to handle that traffic. It is typically required by Council for medium to large-scale planning permit applications.
What are the key components of a TIA?
A TIA includes traffic counts, analysis of existing road conditions, calculation of trip generation rates, intersection capacity analysis (often using SIDRA or similar software), and recommendations for necessary infrastructure upgrades.
How long does a TIA take to complete?
The timeline depends on the complexity and the need for data collection. On average, a TIA can take anywhere from 1 week to 4 weeks depending on the complexity. Generally Quantum Traffic will ndeavour to meet the Client’s expectations around timeline, where possible and achievable.
What is a Traffic Impact Assessment (TIA) Report?
A TIA is a report required by a Responsible Authority (local Council/Government) or a Referal Authority (TfNSW, Main Roads, DTP, etc) and assesses the potential traffic, parking, design, queuing and road safety impacts of a proposed development/use on the surrounding road network.
When am I required to submit a TIA?
A TIA is typically required as part of a Town Planning Application for a new development or a change in land use. It may also be requested in a Request For Information (RFI) response from the Council to progress your application.
How does a TIA assist with project approval?
By professionally identifying and addressing all critical traffic and parking factors, a TIA helps ensure your application has the best possible chance of being approved without unnecessary delays by providing confidence to decision-makers.
What specific traffic issues are covered in a TIA?
The report specifically addresses the traffic impacts on surrounding road networks, potential parking overflow impacts, and road safety issues relating to access and movement.
Does every project require the same level of Traffic Impact Assessment detail?
No. The complexity varies by project size and scope. The report can range from a comprehensive study to a shorter statement of effect, compiled as per industry standard.
What types of developments can Quantum Traffic prepare TIAs for?
Quantum Traffic have extensive experience preparing TIAs for a wide range of uses, including residential, public, and commercial projects at various scales, covering both new developments and change-in-use applications.
