Traffic Impact Assessments in Melbourne & Victoria
Supporting Development Applications
Traffic Impact Assessments for Planning
A Traffic Impact Assessment is the report councils and DTP ask for when they need to be satisfied your development can be accessed and parked safely without overloading the surrounding network. It backs your planning permit under the Planning Scheme and gives the responsible authority the evidence to grant it.
We've prepared TIAs for everything from infill subdivisions to access strategies on North East Link and the Level Crossing Removal Program. The aim is simple: a clear, defensible report that answers the council traffic engineer's questions before they're asked, and gets your application moving.
Why Fresh Engineering
- Traffic Management Designer (TMD) Cat 1, 2 & 3
- Accredited Road Safety Auditor
- 15+ years, council to Tier 1 projects
- AGTTM & Austroads compliant
- Melbourne metro & regional Victoria
When you need a TIA
Most permits for higher-traffic uses trigger one, and your council will usually flag it at the pre-application stage. Talk to us early and we'll confirm scope before any work starts.
- Service stations, childcare, supermarkets, drive-throughs
- Subdivisions and multi-unit residential
- Industrial, warehousing and freight uses
- Any new or altered access to a declared road
- Car parking shortfalls under Clause 52.06
How we do it
We scale the analysis to the proposal, so a small site isn't carrying the workload of a regional centre. Where access touches a declared road, DTP is a referral authority and we'll set scope to suit them up front.
- Confirm permit triggers and referral requirements
- Survey existing conditions and check crash history
- SIDRA intersection modelling for the design horizon
- Access, sight distance and swept paths to Austroads
- Movement and Place context where it applies
What you get
A lodgement-ready report written for the decision-maker, not buried in model output. We stay on after lodgement to answer council or DTP requests for further information.
- Permit-ready TIA with documented assumptions
- Intersection results: saturation, delay, queues
- Parking and loading against Clause 52.06 and AS 2890
- Practical treatment recommendations
- RFI responses and VCAT evidence if needed
Frequently Asked Questions
When does a TIA get required for a Victorian planning permit?
Generally when a development adds notable traffic, changes site access, or accesses a declared road where DTP is a referral authority. Your council will confirm it at pre-application, or we can advise on your site.
How long does one take?
Usually two to three weeks once we have plans and surveys. New traffic counts add lead time since they must avoid school holidays and atypical conditions.
Will it stand up at VCAT?
Yes. We use recognised Austroads methodology and transparent assumptions throughout, and we can give expert evidence and respond to council, DTP or objectors if it goes to a hearing.
How much does a TIA cost?
It scales with the proposal. A small infill development with simple access costs far less than a service station on a declared road with SIDRA modelling and DTP referral. Traffic counts, if new ones are needed, are the other variable. Send us the plans and we'll scope and quote it.
Do I need new traffic counts?
Not always. Where recent, representative data exists we use it. New counts are needed when the network has changed or the council or DTP asks for current data, and they have to be collected on typical days, outside school and public holidays, which is what adds lead time.
Can the TIA cover car parking as well?
Yes. Most of our TIAs include the Clause 52.06 parking assessment and an AS 2890 layout check in the same report, and where you're seeking a reduction we can fold the demand assessment in too. One consolidated report is usually easier for the assessing planner.
