Can’t achieve your dynamic deflection requirements at an isolated hazard along your continuous barrier? Consider reducing the post spacing at that point. When utilised, the reduced post spacing of 1.0m should extend from a point 10m prior to the approach end of the...

Congratulations to Thailand's Department of Rural Roads (DRR) on winning an IRF Global Road Achievement Award in the safety category. This outstanding achievement is for their Integrated Road Safety Management System Development Project. Over the last four years, Safe...

How to score likelihood Likelihood refers to factors that influence driver error rates, or things that affect the probability of a crash, regardless of traffic volume. For example, consider a rural T-intersection with clear lines of sight in all directions versus an...

Congratulations to our Research and Evaluations Lead Dr. Tana Tan for being awarded the 2020 Australasian College of Road Safety Young Leaders Oration Award. This award recognises his inspiring work and leadership in road safety. He was selected by the College Fellows...

Our Principal Engineer, Kenn Beer, will be presenting at the first of a series of road safety seminars hosted by RACV, AITPM and the Australasian College of Road Safety.Kenn will be presenting alongside Dr Marilyn Johnson and between them​​ they will lead the...

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...

The ‘Dilemma Zone’ at traffic signals is the period in time and space when a driver is unsure if they will make it through the traffic signals before they turn red.Narrowing the Dilemma Zone can assist in reducing the likelihood of crashes. This can be achieved in a...

Likelihood is relative The probability of a crash occurring at even the most dangerous locations on the road network is extremely small on a per-vehicle basis. So how can we ever justify a likelihood score of more than 1 (highly unlikely)? The number of vehicles...

How to assess bicycle facilities One complicating factor with bicycle facilities is that even with off-road paths, some cyclists will choose to ride on the road. It is tempting to eliminate the cyclists on the path as they are not directly exposed to traffic. However,...

The height of a road safety barrier is an important feature to ensure that it contains and redirects a vehicle. 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...

How to score exposure Exposure is the number of times, or for how long, road users are exposed to a hazard. This is mainly driven by trafficvolume (the more traffic (or pedestrians, cyclists, motorcyclists), the more likely a hazard will cause a crash). On the face of...

When conducting Road Safety Audits, it’s essential to consider the point of view of different road users. Recently, our Senior Road Safety Auditor Max McCardel led an audit that involved changes to existing bus stops and parking arrangements. To experience how the...

A Barnes Dance (aka Scramble Crossing) lets pedestrians cross in all directions. This treatment can reduce pedestrian crashes by up to 51%, but may actually increase crashes for other vehicles (Chen et al, 2012). In terms of efficiency, they can increase both the...

The Government of Québec has started attaching speed advice displays to children to remind drivers why they need to slow down. The speed radar (not located on the children) sends the vehicle speed to the variable electronic sign on the child’s back. (it’s also...

Freeway ramp metering can reduce crashes by up to 36% (Liu and Wang, 2013). The signals reduce the incidents of rear end and side swipe crashes by smoothing the flow of vehicles on the mainline.
