Assessments of future maintenance needs, levels of effort, and costs have traditionally been expressed through predictions of maintenance supply (generally in units like dollars or man hours per lane mile). Although this approach is adequate for many management needs, it does not enable one to explore systematically the effects of changes in maintenance policy on future costs and road performance. However, the increasingly important strategic role to be played by maintenance and rehabilitation, and higher costs of providing maintenance services, have recently focused attention on better management practices to define maintenance demands, establish priorities among maintenance activities, and relate alternative policies to future impacts on road service. This paper describes the development of demand-responsive concepts for maintenance planning and policy formulation, based upon work conducted in separate projects for the Commonwealth of Massachusetts and the Federal Highway Administration. Analytical components of the demand-responsive approach include (1) numerical measures of maintenance levels of service, or quality standards; (2) quantitative model to predict the condition or deterioration of specific road features as a function of the relevant physical, environmental and traffic factors; and (3) quantitative models to assess the impacts of maintenance performance, as for example in the areas of preservation of investment, user consequences, and accident prediction.
