It turns out that the features – on roadside poles and on the road surface – are part of a trailblazing new experiment into motorcycle casualty reduction, launched by Transport Scotland.
The eye-catching new ‘user information’ – devised by a research team including road safety specialists at Open Road Simulation Limited (ORS) – uses ‘applied’ or ‘nudge’ psychology to influence bikers on their choice of speed, positioning and braking as they approach challenging bends.
So far the signs and markings, dubbed PRIMEs, or ‘Perceptual Rider Information to Maximise Expertise/Enjoyment’, have appeared at four sites on three different roads frequently singled out by riders seeking a mix of challenging bends, fast straights – and stunning scenery.
So what’s the big idea? Professor Alex Stedmon of ORS, says motorcyclists are often ‘difficult to reach and engage with’ on matters of road safety. In addition, they tend to adapt to conventional road safety messages so that their effect wears off over time. “We wanted to try something new and engaging,” says Prof Stedmon, (the world’s first Professor of Motorcycling).
Intriguingly, the precise way in which these radical new PRIMEs influence riders can’t be revealed – in case it affects the scientific trials and research data. What scientists will reveal, however, is that the mystery PRIMEs consist of upright sign posts at the roadside, and markings painted directly on the road surface, on the approach to bends, to ‘prime’ riders’ behaviour.
The blue roadside signs display an image of a motorcycle, above which is an arrow pointing in the direction of travel. Above that are short, slanting white lines. The white lines are repeated at set intervals on the approach to the bends on the actual road surface.
