With more than two decades of experience delivering technically rigorous and commercially aligned outcomes, Ayen Consulting provides specialist traffic engineering, transport planning and infrastructure design services across Wollongong, the Illawarra Region and broader New South Wales.

We support private developers, architects, planners, builders and government authorities with practical, evidence-based transport advice tailored to the NSW planning framework and the unique transport challenges associated with coastal, escarpment and urban development throughout the Illawarra.

Our approach is analytical, responsive and development-focused, recognising the strong growth occurring across Wollongong, Shellharbour and surrounding suburbs, including increased demand for residential subdivisions, medium-density housing, mixed-use developments and industrial projects.

Wollongong’s transport environment is heavily influenced by its linear coastal geography, constrained east-west connections, and reliance on key regional transport corridors such as the Princes Motorway (M1), Memorial Drive, Appin Road, and the Princes Highway. The region also experiences significant commuter travel between Wollongong and Sydney, as well as freight activity associated with Port Kembla, industrial operations, and regional logistics movements throughout the Illawarra.

These conditions create complex traffic and access considerations requiring practical, compliant and site specific engineering solutions.

Development-Focused Transport Planning

We prepare Traffic Impact Assessments (TIAs), Transport Statements and Technical Notes to support Development Applications (DAs) throughout Wollongong and regional NSW.

Our assessments consider:

Residential subdivision traffic impacts;

Medium-density and mixed-use developments;

Site access and driveway design compliance;

Parking demand and servicing requirements;

Intersection performance and road network impacts;

Freight and industrial traffic considerations; and

Compliance with Austroads, Australian Standards and council-specific DCP requirements.

We regularly support developments across both greenfield growth areas and constrained urban infill sites where traffic and access outcomes are critical to achieving planning approval.

Residential Access Design & Swept Path Analysis

A significant portion of our work involves residential subdivision developments, townhouse projects and infill housing requiring detailed access design and vehicle swept path analysis.

We undertake detailed modelling to demonstrate compliant vehicle manoeuvring for:

B85 design vehicles;

Passenger vehicles accessing garages and basement parking;

Waste collection vehicles;

Emergency service vehicles; and

Service and delivery vehicles.

Our assessments commonly address council requirements for:

Forward entry and exit movements;

Minimum 300mm clearance to walls and obstructions;

Forward and reverse manoeuvring into garages;

Driveway width and ramp transition compliance;

Turning path compliance within constrained sites; and

Safe internal circulation within townhouse and multi-dwelling developments.

We regularly assess whether B85 vehicles can safely access and manoeuvre within developments in accordance with AS2890 requirements and council engineering standards.

This is particularly important throughout Wollongong and the Illawarra, where steep topography, narrow sites and constrained access arrangements frequently create complex design challenges.

Car Park Design & Optimisation

We deliver efficient and compliant parking layouts tailored to Wollongong’s evolving urban environment and development constraints.

Our designs prioritise:

Functional vehicle circulation;

Compliance with AS2890 parking requirements;

Efficient use of constrained development footprints;

Safe pedestrian interaction;

Sight distance and access safety; and

Practical manoeuvring outcomes for real world vehicle operation.

We regularly prepare layouts for:

Residential flat buildings;

Townhouse developments;

Childcare centres;

Industrial developments;

Commercial sites; and

Mixed-use developments.

Parking & Traffic Surveys

We undertake parking stress assessments and traffic surveys throughout Wollongong and the Illawarra Region to support development applications and operational reviews.

Our assessments support:

Residential and mixed-use developments;

Childcare and educational facilities;

Retail and commercial developments;

Industrial and logistics projects; and

Council planning and compliance requirements.

We account for commuter traffic patterns, tourism activity, university-related travel demand and freight movements associated with Port Kembla and major industrial precincts.

Road Safety Studies & Access Reviews

We deliver Road Safety Studies, access reviews and collision analysis for developments and existing road networks throughout Wollongong and regional NSW.

Our assessments include:

Sight distance assessments;

Access safety reviews;

Intersection performance analysis;

Internal circulation reviews;

Vulnerable road user considerations; and

Identification of practical mitigation measures.

We regularly assist clients in resolving council concerns relating to driveway safety, steep site access, vehicle conflicts and constrained access arrangements along busy arterial and collector roads.

Site Traffic Management Plans (STMPs)

We prepare Site Traffic Management Plans (STMPs) for infrastructure works and operational sites throughout Wollongong and the Illawarra Region.

Our STMPs address:

Construction vehicle access;

Site traffic control measures;

Pedestrian management;

Site servicing and deliveries;

Heavy vehicle routing; and

Construction traffic management staging requirements.

All plans are prepared in accordance with Australian Standards, Austroads guidance and Transport for NSW requirements.

Frequently Asked Questions about Traffic Engineering & Transport Services in Wollongong

Do I need a Traffic Impact Assessment for my development in Wollongong?

Many developments throughout Wollongong and the Illawarra require a Traffic Impact Assessment to support a Development Application, particularly for residential subdivisions, multi dwelling housing, childcare centres, commercial developments, and industrial sites. We can advise on the appropriate scope of assessment based on council requirements, road classification, and development scale.

What is a B85 vehicle assessment?

A B85 assessment demonstrates that a standard passenger vehicle can safely access, manoeuvre, and exit a development site in accordance with Australian Standards and council requirements. This commonly involves demonstrating forward entry and exit movements, garage manoeuvring capability, reverse manoeuvring compliance, minimum clearance to walls and obstructions, and compliance with AS2890 turning path requirements.

Can you undertake driveway and garage swept path analysis in Wollengong?

Yes, we regularly undertake detailed driveway and garage manoeuvring assessments for residential developments throughout Wollongong and regional NSW. This includes demonstrating 300mm clearance requirements, forward and reverse manoeuvring, basement access compliance, turning movements within constrained sites, and vehicle accessibility for B85 design vehicles.

Can you assist with steep or constrained sites?

Absolutely, as we frequently work on developments involving steep topography, narrow lot frontages, basement parking constraints, existing structures, limited manoeuvring areas, and complex council access requirements. Our focus is to develop practical, compliant, and cost effective design solutions that support planning approval outcomes.

Do councils require vehicles to exit in a forward direction?

In many cases, yes, councils commonly require developments to demonstrate safe forward entry and exit movements, particularly onto arterial roads, collector roads, or constrained access points. We assess and model these requirements as part of our swept path analysis and access design services.

'Excellent and very professional service provided by Ayen Consulting to support our Local Plan objection. Efficient data collection with robust analysis and clear presentation in a comprehensive technical report; all completed within a very tight timescale.'

ANDREW GUTTRIDGE

'Our Grassroots football club have made an application to build a clubhouse to improve facilities. The project has some complicated objections around car parking and traffic management. As a club we had no experience or knowledge with regards to this and needed a consultant to work with. I approached Kevin and from the outset it felt like he understood our needs, talked us through the process, created a high quality piece of work and met all deadlines asked of him. We are grateful for all of the work and support given to us and wouldn't hesitate to recommend Ayen Consulting for this kind of work.'
