The project will enhance the calculation of the value of maintenance work outstanding on the local road network. Factors previously used (derived from Highways Agency, ie trunk road, data) are not reliable when used for local roads' backlog of maintenance. Four factors are to be calculated, for Urban Principal, Urban Non-Principal, Rural Principal and Rural Non-Principal networks using at least 200 inspection sites as a sample from 2000 previous inspections.
A problem with existing data from the NRMCS visual survey is that not all "identifiable" work represents viable maintenance schemes. Isolated defects are in practice too difficult, or at least not cost-effective to treat. Hence there is a need to adjust figures to bring them to a realistic value for work required.
