Safe System for Motorcyclists: the PRIME road markings project summary
Motorcyclists are one of the most vulnerable road users with a small number of vehicles on the road accounting for a disproportionate number of the killed or seriously injured (KSI) statistics.
Perceptual Information for Maximising Expertise or Enjoyment (PRIME) represents a new and innovative approach to motorcycle casualty reduction with the design of dedicated road markings for motorcyclists on approach to potential hazards.
Bespoke 'gateway' PRIME road markings were installed and investigated in Scotland from 2020 to 2022 across 22 trial sites in the West Highlands. With data from tens of thousands of motorcyclists, the results show that PRIMEs have a significant and positive effect on rider behaviour in relation to reduced speeds, better road positions, reduced braking and increased use of the road markings. In many cases the results were sustained over long periods of time, showing that motorcyclists continue to use them.
This presentation will provide a summary of the findings, how they relate to the Safe System and in particular safe speeds, safe road use, and safe roads and roadsides. The backdrop to this work is Transport Scotland's 'Road safety Framework to 2030' with the aim of cutting motorcycle casualties by 30%. The research has been supported by Transport Scotland and the Road Safety Trust, and has also been published as two scientific journal papers in relation to the Safe System philosophy.
