Navigate Brisbane City Council’s requirements with confidence and secure your Development Application approval with an expert traffic engineering report.
Why Your Brisbane Development Application Hinges on a Traffic Engineer
For any significant development in Brisbane, a professional traffic engineering report is not an optional extra—it is a mandatory component of a valid Development Application (DA). Brisbane City Council is focused on managing the city’s growth, which places intense scrutiny on how new projects impact traffic flow, parking, and public safety. Submitting a DA without a compliant and thorough traffic report is a direct path to delays, costly Requests for Information (RFIs), or outright rejection.
A professionally prepared report from an experienced traffic engineer demonstrates due diligence to council assessors. It provides objective proof that your project is safe, accessible, and functional within the context of the existing transport network, significantly improving your chances of a smooth approval.
The Role of Brisbane City Council’s City Plan 2014
The primary regulatory document governing development in Brisbane is the City Plan 2014. Within this plan, the Transport, Access, Parking and Servicing Code outlines the specific rules your project must adhere to. This code dictates critical design elements, including:
-
Minimum on-site car parking rates for different land uses.
-
Design standards for access driveways and crossovers.
-
Requirements for service vehicle access and loading docks.
-
Pedestrian and cyclist facility requirements.
An expert traffic engineer in Brisbane possesses an in-depth understanding of these local nuances, ensuring your plans are compliant from the outset.
Beyond Compliance: Adding Value to Your Project
A skilled traffic engineer does more than just tick council’s boxes; they add tangible value to your development. Through intelligent design and proactive problem-solving, they can:
-
Improve site functionality: Optimise layouts for better traffic flow and user experience.
-
Maximise development yield: Refine car park designs to increase the number of usable spaces.
-
Prevent costly rework: Identify and solve access or manoeuvrability issues during the design phase, not after construction has started.
-
Streamline approvals: A comprehensive and well-justified report can significantly reduce council assessment times.
Core Traffic Engineering Reports for DA Success in Brisbane
To satisfy Brisbane City Council, a DA submission typically requires a set of specialised reports. Each assessment addresses a specific concern the council has about the impact of your development. Together, they form a cohesive argument demonstrating your project’s compliance and viability.

Traffic Impact Assessment (TIA)
A Traffic Impact Assessment (TIA) is often the most critical report for a DA. It analyses the effect your development will have on the surrounding road network, including intersections and local streets. Critically, jurisdiction in Brisbane is split: local roads are managed by Brisbane City Council, while state-controlled roads (major arterials and highways) are managed by the Department of Transport and Main Roads (TMR).
An expert traffic engineer must navigate both sets of requirements. For any project impacting a state-controlled road, the assessment must be prepared in accordance with TMR’s Guide to Traffic Impact Assessment (GTIA). A comprehensive TIA will:
-
Analyse existing traffic volumes and project future traffic generation from your site.
-
Assess the capacity of nearby intersections to handle the additional load.
-
Recommend mitigation measures, such as new traffic signals or intersection upgrades, if required.
Car Parking Design and Demand Assessment
This report ensures your car park is both compliant and functional. It verifies that the layout—including aisle widths, bay dimensions, gradients, and accessible spaces—meets the technical requirements of Australian Standard AS 2890.1.
Furthermore, it calculates the required number of parking spaces based on the rates specified in the City Plan 2014. If your proposal deviates from these rates, a detailed parking demand assessment is required to justify the variation, providing evidence based on site-specific characteristics or proximity to public transport.
Vehicle Swept Path Analysis
A swept path analysis uses AutoTURN (specialised software) to simulate the movements of specific design vehicles as they enter, manoeuvre within, and exit your site. This is essential for verifying that cars, delivery vans, or large service trucks can navigate driveways, ramps, loading docks, and parking aisles safely and without conflict. This analysis is crucial for preventing costly rework of concrete structures and ensuring the final built form is functional for all intended users.
Navigating Common Brisbane DA Roadblocks: A Problem-Solution Approach
With extensive experience as a traffic engineer in Brisbane for DA submissions, we frequently encounter recurring challenges. Identifying these issues early is key to a successful outcome.
For a deeper look at complex cases, visit our articles section.
Problem: Inner-City Sites with Tight Access
Many lots in inner-city suburbs like Fortitude Valley, Newstead, or West End are constrained by narrow frontages or difficult topography.
-
Solution: We conduct detailed swept path analysis to prove that cars and required service vehicles can safely access the site.
-
Solution: We design innovative access solutions, such as car lifts or turntables, that meet council’s stringent safety standards.
-
Solution: For sites well-serviced by public transport, we can justify reduced parking rates through a comprehensive Green Travel Plan.
Problem: Developments on Major Arterial Roads
Projects fronting major roads managed by Brisbane City Council or TMR (e.g., Coronation Drive, Kingsford Smith Drive) face a higher level of scrutiny regarding access safety and traffic flow.
-
Solution: A thorough TIA is prepared to model the development’s impact and demonstrate compliance with TMR’s strict performance criteria.
-
Solution: We design access points to be left-in/left-out only to enhance safety and minimise disruption to high-volume traffic.
-
Solution: We undertake detailed sight distance assessments to ensure drivers exiting the site have clear visibility in both directions.
Problem: Insufficient Car Parking On-Site
The proposed number of car parking spaces does not meet the minimum rate required by the City Plan 2014.
-
Solution: We prepare a detailed Parking Demand Assessment, using survey data and established principles to provide a robust, evidence-based justification for a lower parking provision.
-
Solution: The report cites factors such as high-frequency public transport access, local walkability, and nearby amenities to support the case.
-
Solution: We can propose alternative transport solutions, such as dedicated car share bays or end-of-trip facilities for cyclists, to offset the reduction in private car parking.

Frequently Asked Questions
What is the typical cost for a traffic report for a DA in Brisbane?
The cost varies depending on the project’s scale and complexity. A simple change of use may only require a basic parking assessment, while a large mixed-use development will require a comprehensive Traffic Impact Assessment. We provide fixed, upfront quotes tailored to your project’s specific needs.
How long does it take to prepare a Traffic Impact Assessment?
A typical TIA can take between 2 to 4 weeks to complete. This includes site visits, traffic data collection, analysis, and report preparation. We can advise on a specific timeframe once we understand your project requirements.
What happens if Brisbane City Council requests further information (RFI) on our traffic report?
RFIs are a standard part of the DA process. A professional traffic engineer will review the council’s request, provide a clear response, and make any necessary amendments to the report. Our direct-access model ensures the senior engineer who wrote the report handles the RFI promptly and efficiently.
Do I need a traffic engineer for a small development like a duplex or a minor change of use?
Often, yes. Even small projects can trigger requirements under the City Plan 2014, particularly if they involve a new crossover, an increase in traffic generation, or a shortfall in parking. It is always best to seek expert advice early to confirm the requirements.
What is RPEQ certification and why is it important for my Brisbane project?
RPEQ stands for Registered Professional Engineer of Queensland. It is a legal requirement under the Professional Engineers Act 2002 that professional engineering services in Queensland are carried out or directly supervised by an RPEQ. Using an RPEQ-certified engineer ensures your report is legally compliant and meets the required professional standard.
Can you help with developments outside of Brisbane, like the Gold Coast or Sunshine Coast?
Yes. While we have deep expertise in Brisbane, our senior engineers have extensive experience securing DA approvals with councils across Queensland, including the Gold Coast, Sunshine Coast, Moreton Bay, Logan, and Ipswich.
