Technical Report

This report incorporates recent research, best practice examples, and jurisdictional inputs to propose a set of model national speed limit guidelines for setting speed limits at high-risk locations. The model guidelines represent a harm reduction approach to speed limits, an intermediate step towards the Safe System. The model guidelines are intend...

The Safe System approach has recently been adopted by all Australian jurisdictions as the guiding principle for delivering road safety outcomes. A national roundtable discussion was held to explore the implications of Safe System for the provision and management of road infrastructure. Developments at the national level and overseas were outlined....

An on-road evaluation of two perceptual countermeasure treatments (an enhanced curve post treatment and peripheral transverse edgelines on the approach to an intersection) was conducted over one year to indicate potential for reducing travel speed. Measures included speed and deceleration profiles, braking, and lateral placement observations taken...

Annually across Australia about 1,000 people are killed on roads in rural and remote areas, while approximately a further 26,000 people are injured. Those found to be at most risk are young male drivers, truck drivers, pedestrians and those living in these areas, particularly Indigenous Australians. Key behavioural factors associated with increase...

This paper considers possible long term and short term measures to improve the safety of these routes, through modification of the road environment.

In the framework of the development of the Strategic Plan for road safety in Greece, an extensive review of successful road safety measures world-wide took place, the results of which are presented in this paper. Special emphasis was given to measures, which their effectiveness was proven through quantitative and / or qualitative evaluation. The me...

... Gee (2019) noted that 87% of New Zealand's roads have speed limits that are excessive for the road conditions: a concern equally noted by the most recent Austroads report on regional road safety [3,97]. Also concerning was that in Australia, of all deaths where speed zone was known, approximately one third (36%, n = 1,310) occurred in zones signed at 70 km/h or less (independent of remoteness level); theoretically, the biomechanically tolerable travel speed in the presence of Safe System compliant infrastructure and 5-star rated vehicle design [27,28,[98][99][100]. ...
... Previous studies conducted in Victoria [Tziotis, M. (1993); and Corben, B.F. and Foong, C. (1989)], in which also the effectiveness of similar Black Spot programs has been investigated, found that high safety benefits are achieved through the implementation of Black Spot programs. The reports found that at treated sites casualty accidents reduced by about a third while providing an economic benefit to the community of over $7 for every $1 spent (ie benefit cost ratio of 7.3:1). ...
... The participants agreed that vigilance in road users is an important factor when driving, and in response to emerging road conditions and traffic, including LAVs. Maintaining vigilance can be difficult in the rural road environment due to the variability in traffic, uniformity in the external landscape, and long distances, which can easily contribute to experiences of monotony and fatigue [11,28,30,31]. One insightful participant indicated that individual inattentive drivers pose the highest risk to others in the road environment, and this can relate to any vehicle class which they operate. ...
... If this is true, potential applications are boundless: engineers and architects can construct " smart environments " such as scaffoldings at construction sites and hospital rooms and corridors that may lower fall risk for patients. Such " smart environments " have already been built and applied in vehicular traffic control (e.g., perceptual countermeasures to speeding; Fildes et al., 2005) and demonstrated in the visual guidance of locomotion of insects (Srinivasan, 1998) and humans (Elliott, Vale, Whitaker, & Buckley, 2009). Furthermore, T. M. H. Dijkstra, Gielen, and Melis (1992) discovered that distance to a surface might play a central role in postural sway, as optic flow patterns are larger and more discernible nearby, thus providing more detailed and precise information for maintaining postural stability. ...
