Macrotexture and Crash Risk – Some Recent Findings from Australia and their Implications

The purpose of this paper is to briefly review previous work on macrotexture and crash risk and report two new Australian studies which broadly confirm the results of the earlier work, i.e. that crash risk increases considerably once macrotexture falls below a threshold level. The implications of the findings for road surfacing management are explored, along with the implications for the assessment and management of road surfaces. The importance of road surfacing for good safety performance has been understood from the earliest days of motorized transport. Laser profilometers offer new ways of assessing road surfaces but little has been done to match this information to the crash histories of roads. Macrotexture seems particularly promising as an indicator of satisfactory road surface on high speed roads. Among the issues considered is how well macrotexture predicts high-risk locations compared to current skid resistance measures, high-risk situations that may not be detected by macrotexture alone, and the research required before the feasibility of a surface management regime based principally on macrotexture could be assessed.
