SCANNER surveys were introduced in 2009 to provide network-wide condition assessment of the local A, B and C road network using survey vehicles that travel at traffic-speed measuring the shape of the road surface using laser sensors, and imaging the surface using digital cameras. The collected data is processed and converted into condition parameters, such as rutting, and delivered in a UKPMS-compliant format to local authorities, for loading into their pavement management systems. The data is used within UKPMS-compliant systems to produce the SCANNER Road Condition Indicator (RCI) that is used for nationally reporting the condition of classified local authority roads throughout the UK. It is also used to identify lengths in need of maintenance or further investigation, and to support scheme identification and prioritisation. In addition, the data supports asset valuation, via the Carriageway Condition Index (CCI), which is a methodology recognised by HAMFIG and CIPFA for use in Whole of Government Accounts (WGA) and for reporting within local authorities’ own accounts.
