Abstract

Differential surfacings, particularly coloured ones, have been used more and more on the road network in a variety of situations. New materials have allowed more brightly coloured surfaces to be achieved, and thin surfacings allow colour to be applied on existing surfaces. With these innovations, it is now possible to make more extensive and striking use of colour in road layout. The question though, is it desirable to do so and to what extent?

The purpose of this study, undertaken by Thorburn Colquhoun on behalf of the Traffic Safety and Environmental Division of the Highways Agency, was to identify the existing situations where colour has been used, to evaluate potential benefits in terms of operation and safety, and to establish design guidance principles for its future use.

The study was c6nducted during 1995/6, a time when the uses of coloured surfacing were very new and often experimental. It is a good time now to review the outcomes from this research and to identify the extent to which some form of consensus may or may not have been reached in the ongoing uses of such material in road layout.
