Road Assessment Vehicle (RAV)

Replace manual surveys with safer, faster, and more objective data collection

Built for SCANNER, Trusted Nationwide: Road Assessment with Confidence

WDM’s Road Assessment Vehicles (RAVs) are purpose-built to deliver repeatable, high-resolution road condition data at scale. Designed, developed, and operated in the UK, they form the backbone of SCANNER survey delivery and help local authorities meet their reporting obligations with confidence.

Each RAV captures roughness, rutting, texture, cracking, and geometry – with the option to add edge deterioration and transverse profile analysis. Built for reliability, they operate from walking pace to 100 km/h, collecting validated data across urban and rural environments.

Key capabilities

Highspeed survey capability across all road types
Continuous video imaging at 5m intervals
Automatic crack detection for objective surface defect reporting
20sensor array covering 3.2 m width for rutting, profile, and wheelpath wear
Accurate measurements of gradient, crossfall, and curvature
GPScorrected outputs aligned to OSGR standards
Builtin safety advantage: no onfoot surveys required

Where RAV adds value

Network-scale SCANNER surveys
Safety and performance reporting for principal and classified roads
Targeted condition assessment for high-risk corridors
Lifecycle planning and surface treatment analysis
Supporting NI168/169 and UK National Indicators

Proven on UK roads

RAV technology has been developed and refined over decades, forming the trusted foundation of the UK’s performance-based road condition monitoring strategy. It remains the most widely used system for SCANNER-compliant data collection.
