Road Safety Audits

What Is a Road Safety Audit?

A road safety audit is a formal, independent examination of a road project or existing road environment by a qualified team of road safety auditors. The purpose is to identify features that could contribute to crashes or worsen their severity, and to provide recommendations for treatment before construction is completed or while there is still an opportunity to make cost-effective changes.

Road safety audits are governed in Australia by the Austroads Guide to Road Safety Part 6: Road Safety Audit, now in its sixth edition. Each state supplements this with its own jurisdiction-specific guidelines and auditor accreditation requirements.

The audit process is independent — the audit team operates separately from the design team and reports directly on safety issues without being constrained by design decisions already made. This independence is fundamental to the audit’s value: it ensures the findings reflect genuine safety concerns rather than a review of work by the people who produced it.

Road safety audits are applicable to all road-like environments, not just public roads. RSA conducts audits on car parks, freight centres, logistics facilities, airports, ports, mining sites, and any other environment where vehicles and pedestrians interact.

The Nine Stages of a Road Safety Audit (Austroads Framework)

The Austroads framework defines nine audit stages, each corresponding to a point in the project lifecycle where safety issues can be identified and addressed. RSA is accredited to conduct audits at all nine stages.

Stage 1 — Concept Design The earliest opportunity to identify fundamental safety issues with a project’s overall layout, alignment, and design intent. Issues identified at this stage are the cheapest to resolve — changes to concept designs cost a fraction of changes made during detailed design or construction.

Stage 2 — Preliminary Design Assesses the developing design for safety issues including horizontal and vertical alignment, intersection geometry, sight distances, and the treatment of vulnerable road users. At this stage, the design is taking shape but significant changes remain feasible.

Stage 3 — Functional Design Reviews the design at a level of detail that allows assessment of lane widths, median treatments, turning movements, and pedestrian and cyclist facilities. This is typically the last stage before detailed design locks in the key geometric parameters.

Stage 4 — Detailed Design The most thorough pre-construction review, assessing the full detail of the design including signage, line marking, lighting, drainage, safety barriers, and roadside hazard clearance. This stage identifies issues that, if not addressed, will be built into the infrastructure.

Stage 5 — Temporary Traffic Management — Desktop Reviews the temporary traffic management plans for a construction project before implementation, identifying safety issues for workers and road users during the construction phase.

Stage 6 — Temporary Traffic Management — Implementation A physical inspection of the temporary traffic management arrangements as installed on site, confirming that the desktop plans have been implemented correctly and safely.

Stage 7 — Construction Traffic Management Ongoing audit support during construction, reviewing traffic management as the project evolves and construction staging changes.

Stage 8 — Pre-Opening A critical inspection of the completed road before it opens to traffic, identifying any remaining safety deficiencies that must be addressed before the road is used. This is the last opportunity to identify and fix issues before crashes occur.

Stage 9 — Post-Opening Conducted after the road has been open to traffic for a period — typically six to twelve months — to assess how the road is actually performing, identify any emerging safety issues, and confirm that conditions identified in earlier audits have been satisfactorily resolved.

When Is a Road Safety Audit Required in Australia?

Road safety audits are mandatory or strongly recommended in a range of circumstances across Australia:

State road authority requirements — All state road authorities require road safety audits at designated stages for projects involving permanent changes to road layout on state-managed roads. Requirements vary by jurisdiction but typically cover all significant road projects from concept design through pre-opening.

Local government projects — Many councils require road safety audits as a condition of capital works delivery, particularly for projects on arterial roads, near schools, or involving significant changes to pedestrian and cyclist facilities. Councils procuring Black Spot Program funding are required to demonstrate that treatments are based on a sound safety assessment.

Development applications — Planning authorities frequently impose conditions requiring road safety audits as part of development approvals, particularly for medium to large developments, proposals with direct access to arterial or high-speed roads, and projects near schools or activity centres.

Major infrastructure alliances — Tier-1 construction alliances and contractors on PPP and alliance projects are typically required to engage independent road safety auditors at each design stage. RSA has long-standing relationships with major alliance contractors across Victoria, NSW, and Queensland.

Black Spot Program — Road safety audits are a central component of the federal Black Spot Program process, supporting funding applications and validating the safety basis for proposed treatments.

Post-crash investigations — Following serious or fatal crashes, road authorities and local governments may commission road safety audits or safety reviews to understand whether infrastructure contributed to the crash and to identify treatments.

Road Safety Audits in Victoria — DTP Requirements

In Victoria, road safety audits are governed by the Department of Transport and Planning (DTP), formerly VicRoads. DTP maintains an accreditation and prequalification scheme for road safety auditors, with auditors required to hold current DTP accreditation to conduct audits on state-managed roads.

RSA’s auditors are accredited under the DTP scheme and have an extensive project record across Victoria — from inner-Melbourne freeway infrastructure through to rural highway upgrades and regional town centre improvements.

Key Victoria-specific requirements include:

DTP prequalification — Auditors conducting audits on state-managed roads in Victoria must hold current DTP prequalification. RSA maintains this accreditation across our senior auditor team.

Austroads Guide to Road Safety Part 6 as base standard — Victoria applies the Austroads Guide supplemented by DTP’s own project specifications and guidelines.

Audit requirements for council roads — While DTP requirements apply to state-managed roads, many Victorian councils have adopted equivalent requirements for significant works on local roads, particularly those receiving state or federal funding.

RSA’s Victorian project experience spans the full spectrum of project types and scales — from the West Gate Tunnel and North East Link at the top end, through to intersection upgrades and local road improvements for metropolitan and regional councils. Our Bulleen base gives us a practical advantage in mobilising quickly for metropolitan Melbourne projects, while our team’s regional experience covers the full Victorian network.

Road Safety Audits in NSW — TfNSW Requirements

In New South Wales, road safety audits are governed by Transport for NSW (TfNSW). NSW maintains a Register of Road Safety Auditors with three accreditation levels:

Level 1 — Team Member — Qualified to participate as a team member on road safety audits under the supervision of a Level 3 Lead Auditor.

Level 2 — Auditor — Qualified to lead audits on lower-complexity projects.

Level 3 — Lead Auditor — The highest level of NSW accreditation, required to lead audits on state-managed roads and complex projects.

RSA holds Level 3 accreditation in NSW and has conducted audits on significant NSW projects including the Gateway Upgrade in Sydney and road safety assessments on the state highway network in regional NSW.

TfNSW’s Road Safety Audit Guidelines supplement the Austroads Guide and establish specific requirements for audit team composition, independence, and reporting on state-managed roads. For development-related audits and council projects in NSW, the Austroads Guide applies as the base standard.

Why Choose an Accredited Road Safety Auditor

Not all road safety consultants are road safety auditors. Accreditation under the Austroads framework — and the state-level schemes that build on it — requires auditors to demonstrate specific training, experience, and ongoing professional development. When procuring a road safety audit, confirming auditor accreditation is essential for several reasons:

Regulatory acceptance — State road authorities will only accept audits conducted by accredited auditors. An audit conducted by an unaccredited consultant may not be accepted by DTP, TfNSW, or other state agencies, requiring the work to be repeated.

Independence — Accredited auditors are bound by independence requirements that prevent them from auditing their own design work. This independence is fundamental to the audit’s credibility and legal standing.

Technical currency — Accredited auditors are required to maintain continuing professional development, ensuring their knowledge of the Austroads Guide, state guidelines, and evolving best practice remains current.

Legal exposure — Where a road safety audit is commissioned to discharge a duty of care obligation — for a development approval, a council capital works project, or a Black Spot application — using an accredited auditor is the clearest way to demonstrate that the obligation has been properly discharged.

RSA’s auditor team includes senior accredited auditors with accreditation across all Australian jurisdictions. Our team has conducted road safety audits on more major Australian infrastructure projects than any other specialist firm — giving us the depth of experience to identify issues that less experienced auditors may miss.

Our Road Safety Audit Process

RSA’s approach to road safety audits follows the Austroads framework while incorporating the practical experience accumulated across 30 years and thousands of audits.

Briefing and scoping — We begin by establishing the audit scope with the project team: the stage, the design documentation available, the specific concerns the client wants addressed, and the programme for delivery. Clear scoping ensures the audit is targeted and the report is actionable.

Independent team formation — We assign an audit team that meets the independence requirements for the project and jurisdiction. Our team members bring relevant specialist expertise — whether that is temporary traffic management, safety barriers, cycling infrastructure, DDA compliance, or another specialisation relevant to the project.

Design review — The audit team reviews all relevant design documentation, drawing on the Austroads Guide, state-specific guidelines, and our practical experience to identify potential safety issues before the site inspection.

Site inspection — Where required by the audit stage and available infrastructure, the audit team inspects the road environment or construction site to assess conditions that cannot be evaluated from plans alone.

Audit report — We produce a structured audit report identifying each safety issue, its location, the basis for concern, and a recommended treatment. Reports are clear, concise, and formatted to support the project team’s response and the road authority’s acceptance process.

Follow-up — Where clients require support in responding to audit findings or negotiating treatments with road authorities, RSA’s experience in working with DTP, TfNSW, and other agencies allows us to assist constructively.
