Safeguarding motorcyclists: trialling new PRIME road markings for casualty reduction

Throughout the UK and around the world, motorcyclists represent a uniquely vulnerable road user group.  Traditional approaches to road safety can have limited effect on casualty reduction and limited reach to riders who are typically difficult to engage with (i.e. those who are experienced riders, but who have not taken any further training).

A series of innovative road markings have been designed and trialled in Scotland in order to 'prime' rider behaviour on approach to demanding bends.  The road markings support casualty reduction by providing a tool for riders to use, and to enhance their enjoyment and expertise on the road.

This presentation will introduce the findings from the initial trial of this unique research programme into casualty reduction. Data from almost 13,000 motorcyclists make this the largest programme of work of its kind. Rider behaviour was analysed according to speed, road position and braking using pre- and post-installation datasets.

The findings indicate that the 'PRIME' road markings had a significant effect on rider behaviour and lay the foundation for further trials through 2021, 2022 and beyond.  Given the positive findings to date, there is immense potential for these road markings to be installed more widely as a cheap and easy to maintain approach to casualty reduction.
