Skid Strategy

Building Safer Roads Through Skid Resistance Strategy

A proactive skid resistance strategy helps road authorities identify and address surface safety risks before crashes occur. WDM New Zealand supports this with trusted SCRIM® data, analysis, and technical expertise, helping clients set thresholds, prioritise treatments, and implement evidence-based policies that deliver safer, more resilient road networks.

How it works

  • Assess Network Risk

    Use SCRIM® and texture data to identify high-risk sites such as curves and intersections, creating a clear picture of surface safety across the network.

  • Set Policy and Benchmarks

    Establish skid resistance standards and investigatory levels based on traffic, climate, and road type to prioritise high-risk areas and guide maintenance planning.

  • Monitor and Analyse Trends

    Conduct regular SCRIM® surveys to track performance, combining friction data with crash and geometry records to detect emerging risks before they become issues.

  • Plan and Implement Treatments

    Apply evidence-based treatments such as resurfacing or high-friction surfacing to maximise safety benefits, optimise resources, and extend pavement life.

  • Review and Refine Strategy

    Validate results through post-treatment surveys, feeding insights back into models and thresholds to continuously improve safety and performance outcomes.
