Safer journeys Road safety at Transurban is based on the globally adopted ‘Safe System’ approach, that recognises road safety is a shared responsibility. This means our approach considers the individuals and businesses using roads; the vehicles they drive; and the building and management of both our roads and the wider network. Our road safety performance We track our road safety performance using a Road Injury Crash Index (RICI): the number of serious injury crashes per 100 million vehicle kilometres travelled on our roads. In FY25, our RICI was 4.16, 0.01 above our FY25 threshold of 4.15 (see Figure 22). This equated to 346 crashes. FY25 was a particularly challenging year for our North American assets, with 62 serious injury crashes recorded in this market. The primary contributing factors continue to be distracted driving and speeding. On-road messaging campaigns with police enforcement has shown to assist driver compliance. We are actively collaborating with key regional stakeholders to gain deeper insights into driver behaviour and to design targeted initiatives that enhance road safety across the region.

We use a data analytics platform to detect traffic patterns and driver behaviours that can contribute to both crashes and near- misses – and this data enables us to develop targeted safety action plans. Our vision of zero serious injury crashes remains a key focus. While most crashes on our roads don’t result in serious injury to people in vehicles, we continue to identify and implement initiatives to reduce common crash types on our roads (see case study below). We conduct regular community research into road safety. Our latest Insights Report published in November 2024, identified gaps in road-user knowledge including motorbike and truck blind spots. In response we ran a campaign during National Road Safety Week to encourage all road users to check blind spots when changing lanes. .

Case study Smart roads making journey safer
Rear-end crashes remain the most common crash type on our assets (41%). These are associated with congestion, tailgating and driver distraction. When traffic queues to exit a road, the likelihood of rear-end collisions can increase. We monitor our exits to identify queuing and other potential hazards. For example, we installed an advanced warning system at a collision hot spot at Power Street on the West Gate Freeway, where queuing can impact the Burnley Tunnel.
The system – which automatically measures traffic speed, volume and density – activates warning signage giving motorists early notice to slow down prior to joining the queue. This has helped reduce rear-end collisions at the location by 17.8%. Motorists are also experiencing quicker travel times
with the median speed on the exit ramp increasing by almost 5% in the morning peak.
1 Following internal assurance on vehicle kilometres travelled, the previously reported FY24 RICI reduced from 3.72 to 3.71
