The study began last year and involved a pre-test survey, practical session at the Crashlab in Huntingwood, NSW, and post-test survey and discussion.
Five motorcyclists with a range of riding experience rode over the bumps in straight lanes and on curves, in wet and dry conditions, while braking and accelerating at speeds up to 95km/h. First-aid officers were on site.
Each rider was asked about their perception of safety of ATLM before a practical session riding on ATLM at Crashlab, and then again after the practical session.
After the practical session, all of the participating motorcyclists reported higher confidence in riding over the strips.
Their perception of the safety of the strips on a scale of one to 10 went from 6.75 in the dry to 8.6 and from 5.45 in the wet to 7.60.
Safe System Solutions Research and Evaluations Lead, Dr Tana Tan says riders should still be wary of the road bumps.
“Riders who understand that ATLMs are not as detrimental to a motorcycle’s stability and handling as first thought are still likely to be aware of the presence of ATLMs but perhaps not be as concerned about them as before,” says the Honda VTR1000 rider.
“I would still encourage riders to not ride over them on purpose and treat them as they would any other line marking.”
Centre for Road Safety executive director Bernard Carlon says they will continue to “work closely with peak motorcycling groups” and monitor locations where ATLMs are installed.
“The marking is particularly effective in managing driver fatigue, one of the leading causes of road crashes in NSW,” he says.
“As we continue to monitor the locations where ATLM has been installed, all road users, including motorcyclists, can benefit from the marked improvement in safety they offer.”
