Signposts should be designed to be frangible, meaning they fracture, break away, or bend upon impact to reduce damage to vehicles and the risk of injury to occupants. Smaller signs use posts that deform easily, while larger signposts are equipped with mechanisms that...

In Australia and New Zealand, most motorcycle crashes involve a single vehicle losing control, or cars failing to yield to motorcyclists at intersections. Thankfully, motorcycle-to-motorcycle crashes are rare - though they happen more frequently in group rides, where...

By Dr Tana Tan Research and Evaluation Lead | Safe System Solutions Advanced Driver Assistance Systems (ADAS) play a key role in the Safe System approach to road safety – but what can we do to ensure drivers don’t ‘switch off’ to these features?  ADAS provides drivers...

Across Australia and New Zealand, there are varying views on the placement of slip-based poles within the deflection zone of barrier systems. Historically, the consensus was clear: don’t do it – we don’t know how it will function, thus it’s not acceptable.  However,...

At first glance, central barrier systems might seem like they're only there to prevent head-on collisions. But they actually do much more. These barriers reduce both right and left run-off-road crashes.  A minor distraction or a fatigued driver drifting slightly out...

We've been designing, trialling, and implementing various Vehicle Activated Signs for quite some time now (photo below of some installations back in 2007 in Victoria). With advancing technology, we keep finding even more applications for these signs, including:  Curve...

By Dr Amy Williamson Technical Lead - Safe People | Safe System Solutions In recent years, a slight philosophical division appears to have emerged among road safety professionals about how the human element is addressed in road safety. The 2024 ACRS policy position...

We can’t expect 100% of drivers to comply 100% of the time. While we’ll continue to work to lessen the amount of red-light running, it’s inevitable that some will continue to occur, and we need to think about the severity of these incidents.   This crash looks to be...

What is NRRIT? The Network Roadside Risk Intervention Threshold (NRRIT) has replaced the ‘Clear Zone’ approach to managing and assessing roadside risk in Victoria, Queensland and South Australia. It is a key concept in road safety management, used to determine when...

We often get asked about the effectiveness of convex mirrors and frequently review proposals that include them. There’s a lot of misconceptions out there, so we’ve created a fact sheet to ensure practitioners have the right information at their fingertips.  Convex...

Have experience in the design, delivery, or maintenance of transverse rumble strips? Let us know what worked, what didn’t, and anything interesting about your work. Why do we want to know this?  In 2022/23, Austroads asked Safe System Solutions and our colleagues at...

Content warning: Video shows footage of a real crash. Many of our urban areas are built around large, traffic-carrying roads that cut through busy activity centres. These environments have significant challenges, especially when it comes to the safety of vulnerable...

Almost 40% of deaths and serious injuries in Australia involve a vehicle leaving the road and colliding with a roadside hazard. Of these collisions, the second most common hazards are utility poles (trees being the most common).  Unfortunately, safety considerations...

Kerbs play an important role in road/street design, however their proximity to roadside barriers can create challenges. When kerbs are placed near barriers, they can alter the way vehicles interact with barriers, increasing the risk of underride, override, and vehicle...

While Advanced Driver Assistance Systems (ADAS) improve passenger car safety across many scenarios, they may fail to adequately detect Powered Two Wheelers (PTWs) (motorcyclists) due to their smaller size and potential misjudgement by drivers. This sparked the...

Why are we so passionate about raised crossings? If this video doesn’t say it all, here are a few points:   Enhanced Pedestrian Safety: Raised crossings slow down vehicles, reducing the risk and severity of collisions with pedestrians.  Improved Visibility: Elevating...

We often see lists of Melbourne’s most dangerous intersections published by insurance companies or auto associations. However, these rankings usually focus on all crashes or even congestion, rather than specifically on Fatal and Serious Injuries (FSI). Additionally,...

Trucks pose a higher risk to vulnerable road users like pedestrians, cyclists, and motorcyclists due to several factors:  Size and Weight: Trucks are significantly larger and heavier than cars, leading to more severe consequences in collisions.  Limited Visibility:...
