Resource Allocation Framework to Meet Highway Asset Preservation Needs

State departments of transportation (DOTs) and the federal government have invested significant resources in building our nation's highway system. All of the asset categories that comprise our highway system, e. g., pavements, bridges, traffic signals, drainage pipes, signs, lights, and more, must be maintained, rehabilitated, and ultimately replaced. As our transportation system has aged, system preservation needs have moved to the forefront in the funding priorities of many DOTs. However, resources for highway preservation typically have not kept pace with preservation needs. Most transportation agencies lack sufficient resources to attain and maintain desired service levels for all of their highway assets and must try to optimize the allocation of their limited resources to preserve a diverse portfolio of assets. Given large variations in service lives--e. g., the life of a bridge versus pavement markings--variations in asset class management systems, and the breadth of competing funding needs, the problem of optimizing resource allocations to preservation needs is extremely difficult. A fundamental and practical issue with optimizing resource allocations to the preservation of various asset categories is the identification of common performance objectives that can transcend all of the asset categories that comprise our highway system, and that could serve as basis for optimization. Such common objectives may include, for example, maximizing remaining service life or minimizing long-term costs. A number of optimization models have been developed to assess and help select the best strategy of preservation or replacement alternatives for a given investment level within an asset category, e.g., in pavement management and bridge management systems, but optimization criteria and practical models to allocate resources across a broad array of highway asset categories do not exist. The objectives of this research will be to develop objectives and measures of effectiveness that may be used to optimize resource allocation for preservation of assets across the entire range of highway assets for which a DOT is responsible. The research to accomplish this objective might include the following tasks: (1) preparation of an annotated literature review on optimization criteria and objectives to allocate resources across various transportation asset categories; (2) identification of optimization objectives and criteria that may be suitable to allocate preservation resources across a broad portfolio of highway asset categories; (3) assessment of the potential advantages and disadvantages of the optimization objectives and criteria for use in the intended context; (4) assessment of potential issues associated with implementing the most advantageous optimization objectives and criteria in a practical optimization model within state DOTs; (5) demonstration and documentation of the use of the recommended optimization objectives and criteria in the allocation of resources across highway asset categories through realistic case study examples; (6) identification of specific future research needed to achieve the implementation of allocation optimization models for the preservation of a broad portfolio of highway asset categories within state DOTs. </font></span></div>
