WDM Progresses Towards PAS 2161 Survey Compliance

June 2025

WDM has submitted two data sets for demonstration purposes to TRL for evaluation across the three PAS 2161 sample networks, marking a key milestone in the approval process for its survey methodologies.

The first uses a combination of traditional and new defects collected using the WDM Road Assessment Vehicles. The second employs WDM’s bespoke visual surveying software to capture Road Condition Categories aligned with PAS 2161 standards.

All submitted data, including that from other providers, will be assessed against reference engineer results using the methodology set out in PAS 2161. Once this evaluation is complete, WDM expects to offer PAS 2161-compliant surveys later in 2025.

With extensive experience delivering SCANNER-based road condition data, WDM is uniquely positioned to support both backward compatibility with existing national indicators and forward alignment with PAS 2161 requirements.
