A simplified approach, using limited network-specific data and the recently developed World Bank HDM Manager, was applied to the highway network of Peru to provide interim guidelines on appropriate standards and policies to be implemented, pending the results of a more elaborate study involving a full-scale road condition and traffic inventory. The design of the methodology is described, as is its application to define the best maintenance strategies for paved and unpaved road networks. The order of magnitude of the level of expenditures required is determined, and a tentative prioritization scheme for road activities is developed.
