Fleet vehicles and equipment are important for delivering state highway agency programs, projects, and services, and they compose a major part of agency capital investments. Maintenance forces must be equipped with fleets of adequate sizes, but these assets also require significant resources for recurring maintenance to ensure their operational performance, reliability, and service level. Therefore, there is a trade-off between providing sufficiently sized equipment fleets and minimizing resource investments. In this context, proper management of these equipment fleet assets can significantly reduce costs and provide potential benefits in environmental stewardship. A major portion of the fleet management activities is devoted to measuring, monitoring, and reporting asset utilization levels while meeting highway agency needs. This research is developing utilization measurement models to facilitate the fleet management processes, with the objective of minimizing total costs while satisfying the agency’s equipment needs. The outcome will provide highway agencies with a timely and cost-effective decision-making procedure to determine the optimal fleet size and composition to maintain the desired level of service for state level operations.
