National Highways (NH) manages levels of skid resistance on their network by carrying out single annual skid resistance surveys. These are carried out over the course of the summer and are split over three survey periods. It is known that skid resistance varies during the year and between years, therefore the data is corrected by use of correction factors called LECFs. To monitor the ongoing trends in skid resistance NH established a series of benchmark sites. These sites are surveyed in all three of the survey periods during the survey season. This report discusses the analysis of the data collected in 2021.
