Traffic Impact Assessments (TIA)
We prepare comprehensive Traffic and Parking Assessment Reports in accordance with Transport for NSW (TfNSW) guidelines. Our assessments consider existing site conditions, proposed development layouts, and local traffic environments. Each report includes:
Our Traffic Engineering Approach: Solving Your Biggest DA Challenges
We understand the pressures our clients face. You need a traffic engineering partner who not only produces a report but also protects your project’s viability from start to finish.
Pain Point 1: The Risk of Costly, Unviable Conditions
The biggest risk in the DA process is not just refusal; it’s an approval loaded with unrealistic conditions. A weak TIA invites consent authorities to demand excessive road widening, unnecessary traffic signals, or oversized loading docks,parking areas that can cripple your project’s feasibility, design, and budget.
Our Solution: Our traffic engineering team is renowned for its pragmatic and determined approach and leverage our senior-level experience to negotiate from a position of authority. We defend our analysis and protect your project from costly, unnecessary conditions, ensuring the final outcome is both compliant and commercially viable.
Expert Traffic Engineering for Your Traffic Impact Assessment
A Traffic Impact Assessment (TIA) is often the single most critical and scrutinized element in a Development Application. It is also the most common point of failure.
Vague, incomplete, reports from inexperienced consultants are immediately challenged by local councils and Transport for NSW (TfNSW). This results in costly DA delays, extensive Requests for Information (RFIs), and, in many cases, a complete project redesign, refusal, or an approval with unviable conditions.
This is where the expert traffic engineering of TTPA becomes your project’s greatest asset. Since 1994, Transport & Traffic Planning Associates has been the boutique consultancy trusted by Sydney’s largest developers. We provide evidence-based, robust traffic engineering advice devised to withstand scrutiny, solve complex problems, and secure your development consent.
Pain Point 2: Project Delays from Inexperienced Consultants
Every day your DA is delayed costs you money. Inexperienced consultants often underestimate project complexity, leading to reports that are easily picked apart by the council’s traffic engineering panel. This begins a long, frustrating cycle of RFIs and redesigns, halting your project timeline.
Our Solution: Our reputation precedes us. A TTPA report signals authority and meticulous traffic engineering expertise. We have a proven track record with some of Sydney’s most complex developments (high-rise, industrial, retail, aged care) and anticipate challenges before they become problems. This proactive approach minimises RFIs and streamlines the approval pathway, saving you time and holding costs.
Pain Point 3: Weak Analysis That Fails Under Scrutiny
You cannot afford to submit a TIA built on weak arguments. When Council challenges your traffic generation figures or parking-demand rationale, your consultant must have the empirical data to support their position.
Our Solution: Our entire traffic engineering philosophy is built on evidence and rationale. We conduct rigorous data collection and sophisticated traffic modelling (including SIDRA analysis). This provides a robust, defensible foundation for every recommendation we make. We don’t just provide opinions; we provide robust traffic engineering facts.

Your Traffic Engineering Questions Answered
What is a Traffic Impact Assessment (TIA)?
A Traffic Impact Assessment (or TIA) is a comprehensive technical report, prepared by a qualified traffic engineering consultant. It is a critical and mandatory component of most Development Applications (DAs).
Its purpose is to provide Council and Transport for NSW (TfNSW) with a detailed analysis of a project’s impact on the surrounding road network. It assesses everything from traffic generation, car parking demand, and access safety to loading dock efficiency and pedestrian/cyclist movements.
For TTPA, a TIA is not just a document; it is the primary evidence we build to prove your project is safe, efficient, and appropriate for the site. It is the traffic engineering foundation that secures your approval.
When is a Traffic Impact Assessment (TIA) needed?
A TIA is generally required by council for any Development Application that is likely to generate additional traffic, increase parking demand, or change existing access conditions.
This almost always includes:
- Multi-unit residential (apartment) buildings
- Commercial, retail, or industrial developments
- Aged care facilities, medical centres, and childcare centres
- Educational establishments and Places of Worship
- Land subdivisions (residential and industrial)
- Any project proposing new or modified access to a classified (main) road
Council requirements differ. The most cost-effective step is to contact us early in your design process. We can provide quick, authoritative advice on the exact traffic engineering reports your specific project will require.
How can TTPA help prevent my project from being delayed by Council or TfNSW?
This is one of the most significant risks to a project’s timeline. Delays are often caused by incomplete reports or weak traffic engineering analysis that invites a long list of Requests for Information (RFIs).
Our proven process is designed to prevent this. With over 25 years of experience, we anticipate council objections before they are raised. We deliver a comprehensive, evidence-based TIA that addresses all potential issues proactively. Our established reputation means consent authorities respect our analysis, which streamlines the assessment process and minimises costly delays.
What if Council demands unrealistic or cost-prohibitive conditions for my approval?
A development approval with unviable consent conditions is not a success. This often happens when a consultant lacks the experience to negotiate effectively or defend their analysis.
Our approach is different. We are renowned for being pragmatic, but also determined. We will not simply accept unreasonable conditions. We leverage our deep traffic engineering expertise and sophisticated traffic modelling to negotiate from a position of authority. We find solutions that are both compliant and commercially viable, protecting your project’s feasibility.
When is the best time to engage a traffic engineering consultant?
You should engage us as early as possible, ideally during the pre-DA or even the design feasibility stage.
Bringing us in early allows our senior traffic engineering consultants to identify “fatal flaws” or strategic opportunities before you have committed significant funds to architectural plans. Early advice on-site access, parking layouts, or loading dock geometry can save you millions in redesigns and ensure your project is viable from day one.
My project is large and complex. How do I know you can handle it?
Complex, large-scale projects are our specialty. Our proven track record includes some of Sydney’s most significant high-rise residential towers, large-format retail centres, and major industrial precincts.
We are a high-capacity, senior-led firm, successfully managing over 600 jobs per year. This scale gives our clients a distinct advantage:
- Unmatched Current Experience: Our traffic engineering team has successfully navigated virtually every complex challenge possible.
- Real-Time Authority: Our daily, active relationships with local councils and TfNSW mean our advice is based on what is being approved right now, not on outdated assumptions.
