Placing grates of any sort on bicycle lanes or bicycle/shared paths should be avoided. However, this is not always practicable as storm water drainage structures are usually located along the edge of roads where cycling facilities are likely present. All drainage...

The Department of Transport has just released RDN 04-03 Compact Roundabouts in Rural-High Speed Environments. The document covers site selection and considerations, safety implications, design considerations and the Lance Creek case study. Big effort from the a number...

This free online seminar is a good opportunity to understand the application of road safety star ratings in Australia.Our Principal Engineer, Kenn Beer, will discuss the use of star ratings in Road Safety Audits to strengthen findings and recommendations.To...

Our senior cycling specialist Max McCardel is part of the TAC’s Light Insights Trial (LIT). This innovative technology records Max’s cycling activity and shares data of abrupt decelerations, swerving, road surface roughness, near-misses and a whole lot more. The idea...

Barrier transition done right – Calder Freeway, Victoria Wire rope safety barriers (WRSB) are not designed to be connected to semi-rigid or rigid barriers or bridge ends. However, WRSB can be transitioned to more rigid systems provided that the WRSB overlaps the more...

Trucks are more likely to roll than skid when travelling too quickly through a curve/corner (unlike cars). The trailer(s) tips first due to the high centre of gravity (relative to the prime mover). Changes in superelevation (i.e. crossfall) within an intersection can...

Flaring a barrier end terminal can aid in maximising the protected area when there is insufficient length before the hazard. It can also improve sightlines out of access points or side roads. While the flared portion of the barrier can increase the impact angle (and...

The Global Plan for the Decade of Action 2021-2030 is now available. The plan has the Safe System at its core.Available here: https://lnkd.in/e8ux_Wuf

Pedestrian and cycling underpasses can eliminate exposure to crashes with vehicles. They are a Primary Safe System solution, but sometimes planners and designers are reluctant to include them in a project due to flood risk. We say this should be challenged, and that...

In a 2001 study from the US, the driving records of young drivers were compared with those of their parents. The results showed that a child’s driving record is related to their parent’s driving record. Children whose parents had three or more crashes on their record...

When a vehicle strikes a kerb, it can act like a ramp. The trajectory of the vehicle will depend on the speed, angle, kerb dimensions, vehicle characteristics and more. Upon striking a kerb at speed, an airborne vehicle has the potential to vault an adjacent barrier...

Emergency Brake Assist (EBA) was introduced when vehicle manufacturers realised that 90% of drivers fail to brake with enough force during emergency braking. EBA works by detecting when a driver is about to perform an emergency brake but does not apply full braking...

Thanks to the 40 people that attended the Young Professionals Event as the curtain raiser to the Australasian Road Safety Conference.Thanks also to the wonderful presenters; Paulette Ziekemijjer (TAC), Amanda Stephens (MUARC), Andrew Hardwick (Hard Edge and Re:act)...

Raised safety platform ramps should be designed so that vertical acceleration is kept in the range of 0.4 – 0.7 g for the desired operating speed. Vertical acceleration exceeding 0.7 g is considered too dangerous and may damage vehicles, and below 0.4 g is not enough...

Paul Zlatkovic, Principal Engineer says, "My new role at Safe System Solutions Pty Ltd. has me straight in optioneering Safe System treatments for priority intersections in regional cities in Victoria. As part of this I have assessed the details of past designs,...

In 2013 Austroads conducted focus groups with over 150 road users to understand their attitude to speed enforcement. Participants who said that they at least sometimes drove/rode above the speed limit tended to report that, in the absence of a clear and immediate...

The Austroads Guide to Temporary Traffic Management has been updated and published (https://lnkd.in/guDTVAS7). The Guide provides information on best and harmonised practices in temporary traffic management across Australia. Thanks to Austroads, Richard...

Wide median treatments are commonly found on duplicated rural highways in Victoria where the volume of traffic on side road(s) means it is uneconomical to grade separate the intersection. These intersections are known to be unsafe because they can appear to motorists...

We’ve renewed our corporate support of Victoria Walks.Why?: Over the last five years, an average of 37 pedestrians were killed each year on Victorian roads. This should not be happening. Pedestrians are the most vulnerable road users when it comes to injury, and the...

Lower speed limits reduce both the likelihood of a crash and the severity of any crashes that do occur.With lower speed limits people have more time to react, evade and avoid, and for those crashes that still do happen the kinetic energy transfer to the human is...
