Choosing the right road safety consultant matters. The firm you engage will be named on your audit reports, their accreditation will be verified by your road authority, and their findings will shape the safety outcomes of your infrastructure for decades. RSA | Road Safety Audits has been Australia’s specialist road safety consulting firm since 1994 — the longest continuous run of any privately owned road safety practice in the country.
We work with local councils, state road authorities, Tier-1 construction alliances, legal teams, and private developers across Melbourne, Victoria, and nationally. If your project requires road safety expertise — from concept design audit through to expert witness testimony — RSA has the credentials and the track record to deliver.
Road Safety Consulting Services Tailored to Your Project
RSA is not a generalist engineering firm with a road safety division. Road safety is our entire practice. That focus means every project — regardless of scale — is handled by engineers whose primary expertise is road safety, not traffic modelling, structural engineering, or town planning with road safety bolted on.
Our consulting services cover the full spectrum of road safety work:
Road safety audits — All nine Austroads stages, from concept design through post-opening review. Accredited across all Australian jurisdictions including DTP Victoria, TfNSW, and TMR Queensland.
Safe System assessments — Applying the Austroads Safe System Assessment Framework to evaluate crash risk across the five pillars: safe roads and roadsides, safe speeds, safe vehicles, safe road users, and post-crash response.
DDA and accessibility audits — Disability Discrimination Act compliance audits for pedestrian infrastructure, public transport environments, car parks, and built environments in road and transport settings.
Legal expert witness — Road safety engineering expert reports and court testimony for civil liability matters involving motor vehicle accidents, infrastructure negligence, and coronial inquests.
Traffic impact assessments — Safety-focused TIAs for development approvals, with particular expertise in high-speed road access, school zones, and complex pedestrian environments.
Risk assessments — RSA-methodology risk assessments for car parks, logistics facilities, mining sites, airports, and other off-road environments where vehicle and pedestrian interactions create hazard.
Specialist services — Safety barrier assessment and design, crash investigation and black spot analysis, human factors assessment, temporary traffic management audits, optioneering, tender assistance, and asset condition surveys.
Why Councils and Government Agencies Choose RSA
Government procurement teams and council engineers evaluating road safety consultants are looking for a specific combination: current accreditation, relevant project experience, and the independence that makes an audit report credible to a road authority. RSA delivers all three.
Accreditation across all jurisdictions. Our senior auditors hold current accreditation under the DTP Victoria scheme, the TfNSW Register of Road Safety Auditors at Level 3, TMR Queensland, and equivalent schemes in South Australia, Western Australia, and the ACT. When your project crosses state boundaries or requires multi-jurisdiction acceptance, one firm can cover the full scope.
Independence that road authorities recognise. RSA operates exclusively as an audit and safety consulting firm — we do not design the roads we audit. This structural independence is recognised by state road authorities and gives our reports credibility that cannot be replicated by firms auditing their own design work.
A track record on major projects. RSA has been engaged on the majority of Australia’s most significant road and transport infrastructure projects of the past 30 years, including the West Gate Tunnel, North East Link ($26 billion), Melbourne Metro Tunnel Rail ($11 billion), Cross River Rail ($5.4 billion), and Parramatta Connect Light Rail. Councils and agencies commissioning audits on smaller projects benefit from the depth of experience that comes from working at that scale.
Responsive and direct. As a specialist firm of under 25 people, RSA does not route council enquiries through account managers or junior staff. Project briefs reach the senior engineers who will conduct the work, and response times reflect that.
Our Team of Accredited Road Safety Auditors and Engineers
RSA’s consulting team combines four executives with 20–30+ years of experience each, supported by senior auditors who bring specialist expertise in safe systems, temporary traffic management, DDA compliance, and safety barriers.
Raj Muthusamy — Director & Founder Thirty years in road design, traffic engineering, and road safety auditing. Led audits on West Gate Tunnel, Parramatta Light Rail, and Cross River Rail. Specialist in safety barrier systems and Safe System design. Expert legal witness.
Peter Harris — Principal Approximately 20 years of experience including a career background as a traffic engineering and road safety professional with VicRoads. Expert legal witness. Extensive experience across the full range of audit stages and project types.
Mike Game — Senior Auditor & DDA Consultant Deep expertise in safe system assessments, temporary traffic management, and risk assessment. Led audit work on West Gate Tunnel, Metro Tunnel, and M80 Ring Road. Background in manufacturing and logistics brings practical knowledge of off-road environments.
David Graham — Executive Twenty-plus years as a transport engineer and road safety auditor. Accredited senior auditor across all stages. Former Director at GTA Consultants and Senior Principal at Stantec, with a broad project record across Victoria and nationally.
Our senior auditors — including Ray Bozorgmehrnia, Abbas Haydous, Geoff Hepworth, Yasindu Liyanaarachchi, Robin Mathew, and Kimmy Wong — bring additional depth across specialist areas. RSA also actively recruits and develops junior auditors, ensuring the firm’s knowledge is continuously refreshed.
Full-Service Road Safety Consulting — Audits, Safe System, DDA, Expert Witness
One of the practical advantages of engaging RSA is the breadth of capability within a single specialist firm. Many road safety projects involve more than one type of work — a major road upgrade might require a Stage 4 detailed design audit, a DDA accessibility audit of the pedestrian environment, and a Safe System assessment of the corridor’s crash history. Engaging a single firm with expertise across all three avoids the coordination overhead and potential inconsistencies of using multiple consultants.
RSA’s integrated capability also means that findings from one assessment inform others. A DDA audit may surface issues with TGSI placement at a pedestrian crossing that are also relevant to the road safety audit’s assessment of vulnerable road user safety. A Safe System assessment of a corridor may identify risk factors that inform the scope of a subsequent audit. This integration is only possible when the same team is across the full picture.
Projects Across Melbourne, Victoria and Australia
RSA is headquartered in Bulleen, inner-east Melbourne, and operates nationally. Our project record spans all Australian states and territories, with particular depth in Victoria, NSW, and Queensland.
In Victoria, our work covers the full spectrum — from Melbourne’s major freeway and rail infrastructure through to regional highway upgrades in Gippsland, the Wimmera, and northeast Victoria, and local road and intersection improvements for metropolitan and rural councils. Our proximity to Melbourne’s major infrastructure corridors means we are well-positioned to mobilise quickly for metropolitan projects, while our regional experience gives us practical knowledge of the road environments outside the city.
In NSW, we have conducted audits on Sydney’s Gateway Upgrade, the Parramatta Light Rail corridor, and road safety assessments on the state highway network in regional NSW including Wagga Wagga and Inverell.
In Queensland, our work includes Cross River Rail in Brisbane, Legacy Way, the Springfield Rail Link, and road projects across southeast Queensland and regional centres.
We have also completed work in South Australia, the ACT, and internationally in New Zealand and Asia.
How We Work With Clients — From Brief to Delivery
RSA’s engagement process is direct and straightforward, designed to minimise overhead for busy project managers and procurement teams.
Initial enquiry and scoping — Contact us with your project details — the audit stage required, the design documentation available, your programme, and any specific requirements of the relevant road authority. We will confirm the scope, the audit team, independence, and a fee within 24 hours for most standard enquiries.
Proposal and engagement — For straightforward audits, we can typically issue a proposal within one to two business days. For more complex engagements involving multiple stages or specialist work, we discuss the scope in more detail before issuing a fee proposal.
Audit delivery — We work to the programme agreed at scoping. If documentation arrives late or the scope changes, we communicate the impact on delivery promptly rather than absorbing delays silently.
Report and follow-up — Audit reports are delivered in a format accepted by the relevant road authority. Where project teams need assistance responding to audit findings or engaging with a road authority on disputed treatments, our experience across DTP, TfNSW, and other agencies allows us to assist constructively.
Frequently Asked Questions About Engaging a Road Safety Consultant
Do we need a road safety consultant or a road safety auditor? The terms are often used interchangeably, but there is a meaningful distinction. A road safety auditor is specifically accredited to conduct formal road safety audits under the Austroads framework and state schemes — producing reports that are accepted by road authorities. A road safety consultant may provide broader advisory services without necessarily holding audit accreditation. When your project requires an audit report that will be submitted to DTP, TfNSW, or another road authority, you need an accredited road safety auditor. RSA holds both designations.
How do we verify a consultant’s road safety audit accreditation? Accreditation can be verified through the relevant state road authority. In Victoria, DTP maintains a register of prequalified auditors. In NSW, TfNSW maintains the Register of Road Safety Auditors. We can provide evidence of our current accreditation status on request.
Can RSA work as a subconsultant to our engineering firm? Yes. RSA regularly provides road safety audit services as a subconsultant to larger engineering firms, major project alliances, and construction contractors who require an independent auditor. Our independence from design work is maintained regardless of the contractual arrangement.
What information do you need to provide a fee estimate? The audit stage, an indication of project scale and complexity, the volume of design documentation to be reviewed, whether a site inspection is required, and any specific road authority requirements. For standard project types, we can provide a fee range based on this information alone.
Do you work on projects outside Victoria? Yes. We hold current accreditation in all Australian states and territories and regularly conduct audits interstate. Travel costs are included in our fee proposals for projects outside metropolitan Melbourne.
