Tracking our safety performance
Road incident performance
Overall road safety performance
Data showing our overall road incident performance, including how we are tracking over time.
Overall crash data
Road Injury Crash Index
Crashes on our roads are trending downwards
Reducing crashes is an ongoing process, encompassing every element of road travel, in line with the safe system approach discussed here. Every improvement we make contributes to overall crash reduction—and we’re always exploring new technology that will help improve the safety of our roads.
The chart shows our approach of continually introducing targeted and overall safety enhancements is reducing serious-injury crashes.
As this chart shows, our approach is also slowing the rate of non-injury crashes over time.
We note this chart combines serious injury and minor injury crashes as one category: injury crashes. See below for our crash-type definitions.
Understanding crash definitions
Our crash severity definitions may vary slightly from those used by other road safety authorities and reporting bodies.
Our crash severity definitions are:
A crash where no one received an injury.
Minor injury crash
A crash where someone needed first-aid but did not need ambulance transportation.
Serious injury crash
A crash resulting in someone being transported by ambulance.
Road Injury Crash Index (RICI)
Our RICI represents the number of serious injury crashes per 100 million vehicle kilometres travelled (VKT) on our roads.
Our RICI has been trending downwards, even as VKT have increased on our roads over time (and acknowledging pandemic impacts have created some data anomalies). Our RICI averaged 4.6 for the six financial years 2015–20.
Latest RICI numbers
RICI achieved 2020–21
RICI target 2020–21
For the 2020–21 Financial Year, we set a RICI target of 4.5 injury crashes per 100 million VKT. We exceeded this target with a RICI of 4.29.
Australian road safety performance data
The Australian road safety data shown here encompasses the entire Australian road network (including unsealed roads, for example). The most recent Australian road safety performance data shows:
road user fatalities in 2020,
down from 1,186 in 2019
Australians were admitted to hospital
with serious injuries following a crash
of people hospitalised following a crash had high threat to life injuries (2018 latest available figure)
Road infrastructure safety performance
Assessing our road infrastructure’s safety performance
We engage independent agencies to assess our road infrastructure’s overall performance, including safety performance. These assessments apply internationally established and/or rigorously developed criteria to determine our performance.
Monash University Accident Research Centre (MUARC)
MUARC is a world leader in injury prevention research, underpinned by scientific and academic excellence. We engage MUARC to conduct independent assessments of our road’s safety performance, focused on crashes and crash outcomes.
Twice as safe as like roads
MUARC’s research found Transurban’s roads are twice as safe as like roads, and that Transurban has significantly fewer injury crashes than like roads. MUARC’s definition of a ‘like’ road is a freeway or motorway located close to a city centre, and other measurement requirements.
“Transurban-operated assets have a superior road safety
performance compared to roads of like, or comparable, function.”
International Road Assessment Program (iRAP)
iRAP is a registered charity that works to eliminate high-risk roads throughout the world. As a public-health organisation, iRAP uses an evidence-based approach to prevent unnecessary road deaths and injuries. In Australia, iRAP assessments are often referred to as AusRAP assessments.
Roads are assessed and awarded a star rating, from 1-Star to 5-Stars, with 5-Star roads the safest possible.
iRAP says that improving the world’s roads to a 3-star or better standard will make a key contribution to meeting the United Nations’ Sustainable Development Goals target of halving road deaths and injuries by 2030.
Our iRAP assessment results
of our roads received a
3-Star or higher iRAP rating
of travel on our roads received a
4-Star iRAP rating
We engage the Australian Road Research Board (ARRB), an independent transport research agency, to conduct iRAP assessments of all our roads.
Safety performance in action
Toll roads must provide value for money, and this includes providing safer journeys for our customers. Transurban roads are high-performance roads—with multiple safety features, rigorous maintenance routines and round-the-clock incident response services.
See our NorthConnex case study below for an example of a high-performance road tunnel.
A closer look at tunnel safety
All tunnels operated by Transurban include multiple safety features—including features designed to keep you safe while on
the road, and features designed to keep you safe during and after an incident. Click the hotspots to see these features.
Measuring our road safety performance
Tracking our progress towards our ultimate road safety goal
Our safe system approach to road safety is an internationally adopted approach: it also informs how we measure our overall road safety performance. Everything we do is aimed at our ultimate target of zero fatalities and serious-injury crashes on our roads.
Safe system approach
United Nations Sustainable
Transurban adopted the safe system road safety approach in 2016. This approach, used internationally by governments (including the Australian Government), international agencies (including the United Nations) and other transport operators, considers all causes of crashes together.
This approach also recognises that collective effort is needed to improve safety, and advocates for integrated solutions encompassing:
The safe system’s principles inform our operations and performance measures, including working towards achieving our ultimate target of zero fatalities and life-changing injuries on our roads.
The safe system approach is integral to how we track, measure and report on our road safety performance.
Our approach aligns with the Australian Government’s National Road Safety Strategy 2021–30 [PDF] that reflects the safe system approach and focuses on strengthening all elements of Australia’s national road transport system through “improvements under three key themes: safe roads, safe vehicles and safe road use”, with speed management embedded within all three themes.
United Nations' Sustainable Development Goals
The safe system approach also underpins the UN’s Sustainable Development Goals (SDGs). We report on our performance against relevant SDGs annually in our Sustainability Supplement report [PDF], a companion to our annual Corporate Report [PDF].
Established actions and targets
SDG3, Good Health and Wellbeing, includes a target of halving road deaths and serious injuries by 2030. We have established a set of actions and targets that help us track how well we are contributing to the achievement of SDG3.
