New Aussie road markings aimed at giving drivers a 'sense of warning'
As authorities grapple with reducing the number of injuries and deaths on Aussie roads, a trial of a new type of three-dimensional road markings has been expanded in Australia's south, prompting a warning to drivers.
Known as 'dragon's teeth', the aim of the road markings is to alert drivers to a change in the road, such as a reduction in the speed limit. The road markings are being trialled in Adelaide as part of a study led by the University of Adelaide's Automotive Safety Research, alongside the Department of Transport.
Making them appear 3D, the triangular blue and white markings may "attract more attention" from drivers and encourage them to slow down as they enter a lower-speed zone, leading road safety scientist at the University of Adelaide Mario Mongiardini told Yahoo News.
They were installed at Magill Road, Magill, and Seaview Road, Henley Beach, in January, and last week two new locations have been added — Beach Road, Christies Beach and Prospect Road, Prospect.
If successful, the markings could be used in high-pedestrian areas across the country, because they can be implemented "cheaply and quickly" by authorities.
Researcher Mongiardini explained to Yahoo this type of road treatment is called a "perceptual countermeasure" because it aims to change the perception of road users.
"The 3D marking is an evolution of an existing treatment which consists of white triangles only," he said. "The idea was to convert them to look 3D to attract more attention, something drivers cannot miss."
The goal was to create a "sense of warning" as drivers move from a 60km/h or 50km/h zone to a reduced 40km/h pedestrian zone.
Due to its relatively low cost and easy installation, which takes just two hours, it is an attractive measure for authorities. "This treatment, compared to other treatments, is definitely way cheaper and quicker," Mongiardini said.
However, he warns that this treatment "is not meant to be installed everywhere", only where it is really needed, where pedestrians could be at risk.
"The idea is to use them only in specific situations, like on a straight road where a speed limit changes, but drivers don't realise that the environment ahead is changing," he explained. It's used as a "heads up".

Results of the trial are due to be collected and analysed later this year, with researchers hoping to see a reduction in speed, even of just four or five kms.
"Speed is the key factor in 99 per cent of crashes," Dr Chris Stokes, another researcher at the University of Adelaide, previously told Yahoo. "The faster you hit an object, the harder the impact is going to be."
"Even a reduction by four or five km is quite a lot," Mongiardini said. "It means that after the treatment has been installed, drivers start to respect the speed limit and be more aware of the environment. We don't expect dramatic changes in speed."
If the trial proves to be "effective at mitigating travel speed", Aussies could see it on a road near them soon.
