Calculation of Local Equilibrium Correction Factors for the 2023 Skid Resistance Surveys

Skid resistance on England's Strategic Road Network (SRN) is managed by National Highways through annual surveys. The data is analyzed to identify sites where resurfacing might be needed to minimize the risk of skidding collisions. The data is also entered in the Key Performance Indicators (KPIs) for Pavement Condition. The surveys are adjusted for seasonal variation by the application of Local Equilibrium Correction Factors (LECF). This document provides a record of the procedure used to derive the LECFs that have been applied to the 2023 skid resistance survey data.
