How can we help?
Planning a new development, construction project, or major site change in Adelaide? A traffic impact assessment (TIA) is often a mandatory requirement before council will approve your application, and getting it right the first time saves weeks of costly delays.
One Stop Traffic Solutions provides professional traffic impact assessment services across Adelaide and South Australia. Our experienced traffic engineering consultants deliver accurate, compliant TIA reports that meet council and DPTI standards, giving your project the green light it needs to move forward safely and efficiently.
With over a decade of experience across commercial, residential, civil, and government projects, we understand exactly what councils need to see — and how to present it clearly and compliantly.
At One Stop Traffic Solutions, our Site Surveys are a critical part of ensuring the success and safety of any traffic management or infrastructure project. We conduct thorough assessments of work zones, construction sites, and event areas to identify potential risks and develop tailored traffic management solutions that prioritise safety and efficiency.
What Is a Traffic Impact Assessment?
A traffic impact assessment is a technical study that evaluates how a proposed development or project will affect the surrounding road network, traffic flow, and road safety. It identifies potential issues, such as increased congestion, unsafe access points, or inadequate parking, and recommends practical solutions before work begins.
In South Australia, TIA reports are typically required by the State Planning Commission, local councils, or the Department for Infrastructure and Transport (DPTI) as part of the development approval process. They are governed by the DPTI Traffic Impact Assessment Guidelines and must be prepared by qualified traffic engineering professionals.
A well-prepared TIA does more than tick a regulatory box. It protects your project from costly redesigns, demonstrates due diligence to stakeholders, and provides a clear, evidence-based plan for managing traffic safely throughout construction and operation.
When Is a Traffic Impact Assessment Required in Adelaide?
You may need a traffic impact assessment in Adelaide if your project involves any of the following:
- New residential or commercial developments that are expected to generate significant additional vehicle movements
- Subdivision or rezoning applications where road access or infrastructure changes are proposed
- Construction projects on or near arterial roads or intersections managed by DPTI
- Large-scale events or temporary site operations with significant traffic generation
- Changes to existing access arrangements such as new driveways, crossovers, or loading zones
- Industrial or logistics facilities with heavy vehicle movements
- Schools, hospitals, or high-density residential projects in areas with existing traffic pressure
If you are unsure whether your project requires a TIA, contact our team for a no-obligation assessment. We will advise you quickly, before you invest time in an application that may be returned by council.
