The objective of the research was to investigate whether any relationship exists between the surface characteristics of the road surface and the accidents that occur, and, in particular, to investigate influencing factors, including:
Wet/dry conditions; the role of splash and spray on skidding and as an impairment to visibility; lighting provision for accidents after dark; the presence of porous surfaces and their effect on skid resistance and speed; the presence or absence of road markings at the road margins; to report on the position regarding relevant research on the role and efficacy of the tyre/road interaction.
The method used was to review the information available on the various aspects and to draw it together into three chapters on surfacings, tyres and accident databases, carrying out additional research as appropriate to each area.
