Traffic Engineering & Transport Planning Services in Sydney, New South Wales

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 Sydney and 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 complexities of Sydney’s urban environment. Our approach is analytical, responsive and development-focused, recognising the increasing demand for residential subdivisions, medium-density housing and constrained urban infill developments across metropolitan Sydney.

Sydney’s transport environment presents unique planning challenges due to high traffic volumes, constrained road networks, varied topography and strict council compliance requirements relating to vehicle access, parking design and manoeuvring. This is particularly relevant for residential developments where councils commonly require compliant B85 vehicle access, swept path analysis and garage manoeuvring demonstrations with minimum clearance requirements.

Development-Focused Transport Planning

We prepare Traffic Impact Assessments (TIAs) and Technical Notes to support Development Applications (DAs) throughout Sydney 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 greenfield growth areas and established urban environments where traffic and access constraints are critical to planning approval outcomes.

Residential Subdivision Access Design & Swept Path Analysis

A portion of our work involves residential subdivision developments and infill housing projects 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 sites and manoeuvre within garages in accordance with AS2890 requirements and council specific engineering standards.

This is particularly important in Sydney, where narrow lot frontages, steep grades and constrained urban sites frequently create complex access and manoeuvring challenges.

Car Park Design & Optimisation

We deliver efficient and compliant parking layouts tailored to Sydney’s urban development environment.

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 Sydney 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 travel patterns, regional freight activity and event-based traffic associated with destinations such as Newcastle CBD, Honeysuckle, Merewether and the Port precinct.

Road Safety Studies & Access Reviews

We deliver Road Safety Studies, access reviews and collision analysis for developments and existing road networks throughout Sydney 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, vehicle conflicts and constrained access arrangements on busy urban and regional road networks.

Site Traffic Management Plans (STMPs)

We prepare Site Traffic Management Plans (STMPs) for infrastructure works and operational sites throughout Sydney and the Hunter 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 Sydney

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

Many developments throughout Sydney and the Greater Sydney region 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 level of assessment based on specific local council requirements, Transport for NSW guidelines, and your 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 Sydney 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 Sydney?

Yes, we regularly undertake detailed driveway and garage manoeuvring assessments for residential developments throughout Sydney and its surrounding suburbs. 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?

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

Do councils require vehicles to exit in a forward direction?

Absolutely, we frequently work on constrained urban sites across Sydney's inner city and suburbs involving narrow lot frontages, steep gradients, basement parking constraints, existing heritage structures, limited turning areas, and complex local council access requirements. Our focus is to develop practical, compliant, and cost-effective design solutions that support planning approval outcomes.

'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.'
