Abstract. Transportation Safety continues to evolve as a significant area of interest and concern. As a result, evaluation of safety from a pavement surface characteristics perspective is also attracting additional interest. Historically, pavement safety assessments have focused on discrete, low density friction assessments with common technology not changing much in the past half century - this notwithstanding significant changes/improvements in automotive braking systems and exploration of alternative methodologies for pavement surface assessment. Not surprisingly, current methodologies continue to involve test tyres assessing frictional resistance. Interest has always existed in exploring the relationship between texture and friction, in part, because texture can be assessed with non-contact technologies. Unfortunately, neither friction nor texture were previously collected with sufficient density and precision to establish any meaningful correlation. With the availability of more comprehensive integrated pavement surface assessments, more detailed investigations and analysis are now feasible.
