In order to maintainsome consistency in the annual reporting NCC have continued to collect CVIdata also and a comparison between the two BVPI condition ratings can be seenin table 14.3.7 below.Table 14.3.7 BVPI Condition Ratings 2005/06 by Scanner & CVIRoad Hierarchy BVPI Condition Ratings -ScannerPrincipal (BV223) 18% 2.36%Classified (BV224a) 15% 7.34%Unclassified (BV224b) N/A 7.62%BVPI / LocalCondition Ratings -CVIFuture ConditionUsing the carriageway performance prediction programme as described insection 14.7.3 it has been possible to assess the future condition (backlog) of thecarriageways for a number of different funding scenarios. Figures 14.3.1 to14.3.3 show how the condition of the carriageways differ over a 28 year periodbased on the Minimum, Existing & Optimum service options as described insection 14.7. This is an ongoing assessment and will be revised as part of theannually plan update.99
