Wire rope systems will deflect more on hot days and less on cold days. The required wire rope tension for a specific installation is calculated using the Annual Average Daily Temperature at site and the Product Manual. It is important for road designers to understand...

Slip base (frangible) poles are designed to shear at the base when impacted by errant vehicles. The height of the shearing plane should be 75mm above ground level with a ±25mm tolerance. Too high and the pole may snag a vehicle. Too low and the pole may not...

We’ve seen lots of crashes involving vehicles vaulting off a ramp-down end terminal, but this one is a first for us.  This should serve as a reminder to all of us that implement solutions on the transport network, they may be viewed through a different lens by...

Julian has been with SSS for 18 months as a Graduate Engineer. As an accredited Road Safety Auditor, he is one of our team delivering on the mission of creating safer roads for our communities. He recently organized an initiative with his colleagues that is close to...

Lowering vehicle speeds in urban areas is proven to save lives and reduce serious injuries, but here are some things that might surprise you:   Safer speeds help make healthier communities.  Lower vehicle speeds create a more comfortable environment for pedestrians...

While we’re not aware of any studies of the impact of spiders on Australian car crash rates (although most of us have encountered a huntsman in the car at one point), we do know that people leave the road for all sorts of reasons – spiders being just one. Falling...

Raised intersections on arterial roads can reduce casualty crashes by up to 40%.  Also known as platform intersections, raised junctions or plateaus, these speed management devices typically aim to reduce the speed of vehicles to 50 km/h or less. The entire...

Last week, Safe System Solutions Pty Ltd had the pleasure of running our highly informative and engaging Cycling Auditor Course in the beautiful city of Warrnambool. The course covered a wide range of topics related to cycling infrastructure, including best practices...

The more pedestrians or cyclists there are, the lower the risk faced by each pedestrian or cyclist. On the other hand, the more motor vehicles there are, the higher the risk faced by each pedestrian or cyclist.   In 2009, Rune Elvik showed that the high injury rate...

 We're well and truly back into the swing of things for 2023 and all geared up to bring you more face-to-face training throughout the year. First up is our ROAD SAFETY AUDIT COURSE, with face-to-face training being held in Melbourne over March 20 & 21, 2023. Led...

When it comes to barrier height, the greatest concern is the barrier being too low as it increases the likelihood of a vehicle vaulting the barrier. Barrier systems have increased in height in recent years to reflect changes in the vehicle fleet, particularly an...

Right turn onto a pedestrian is one of the most common crash types for pedestrian death and serious injury at signalised intersections. This occurs when the driver has the ability to filter at the intersection (i.e. they choose when they turn right).  In many...

Another fantastic Road Safety Barriers Technical Training Course this week in Nerang, Queensland. The training is designed to equip attendees with a comprehensive understanding of the latest techniques and technologies in road safety barriers. Our expert instructors...

Trucks are more likely to roll than skid when travelling too quickly through a curve/corner (unlike cars). The trailer tips first due to the high centre of gravity (relative to the prime mover). Trailers can roll with an incline of as little as 15 degrees while the...

A see-through effect is part of the ‘visual deceit’ family of crash causation. This occurs when a driver or rider misses the requirement to give-way or stop because the road geometry misleads them. It is common at crossroads, where traffic signals are in close...

Are you struggling with your left turn swept path for larger vehicles in your roundabout design? Instead of increasing the curve radius and increasing the design envelope, have you considered requiring larger vehicles to turn 270 degrees to make their left turn? This...

Does the community know that it’s a “Limit, Not a Target”? In difficult driving conditions, certain speeds, even within the legal limits, may be inappropriate. Wet weather and other influences may mean that driving at the speed limit is inappropriate and dangerous. ❓...

Pedestrian crash risk dramatically increases around public transport stops. This is because people’s focus is on catching their bus/tram/train. In an audit of 70 bus stops in Melbourne and regional Victorian cities, Victoria Walks found that 60km/h was the most common...

Our roads are getting safer… unless you’re a Vulnerable Road User (VRU).Once again we’ve seen a year where a horrific number of people were killed on Victorian roads. 240 members of our community had their lives cut short, their families shattered, their community...
