New 3D road markings have been installed on Adelaide roads in an attempt to improve pedestrian safety.
The new “Dragon Teeth” markings are a result of a partnership between the University of Adelaide and the South Australian Department for Infrastructure and Transport.
Dr Mario Mongiardini, from the university’s Centre for Automotive Safety Research said blue and white 3D-style triangles had been installed to create an “optical illusion”, making drivers aware they were approaching a 40 km/h zone with high pedestrian activity.
Dr Mongiardini said the project aimed to slow motorists in busy suburban business and pedestrian areas.
“The whole idea is to use this 3D marking design to give motorists an effective visual ‘heads-up’ of the change of road environment ahead,” he said.
“The marking comprises a series of simple triangle shapes located alongside both sides of the travel lane leading into the 40 km/h section.
“These triangles appear to be slightly floating over the road surface through a perceptual visual illusion.
“Additionally, a purposely designed change in the gap between consecutive shapes and their size is expected to further induce a traffic calming effect.”
Dr Mongiardini said this type of floating 3D road marking had the potential to catch motorists’ attention, induce a sense of warning, and improve awareness of pedestrians.
“It is expected to make drivers aware of the changing road environment ahead and encourage them to reduce speed, ultimately enhancing pedestrian safety in that critical section of the road.”
He said similar 3D markings had been successfully implemented in Singapore, particularly at boulevard-style entries to 30 km/h zones that large numbers of pedestrians frequent.
