State transportation officials at all levels face the task of managing a wide range of assets to meet public, agency, and legislative expectations. These assets include the physical transportation infrastructure (e.g., guideways, structures, and associated features and appurtenances) as well as other types of assets: e.g., an agency's human resources, financial capacity, equipment and vehicle fleets, materials stocks, real estate, and corporate data and information. This study therefore interprets transportation asset management as a strategic approach to managing physical transportation infrastructure. Transportation asset management in this context promotes more effective resource allocation and utilization based upon quality information.
