"Roadway infrastructure within the United States includes features such as roads, bridges, signs, pavement markings, traffic signals, support commerce and mobility, and is, in essence, a shared financial public resource worthy of being managed at the highest level of efficiency. State departments of transportation (DOTs), local transportation authorities, and federal agencies responsible for the fiscal management of the transportation system have shown a growing interest in advancing the state of practice in managing these critical assets. In addition, the recent congressional passage of Moving Ahead for Progress in the 21st Century Act (MAP-21 Act) has established an outcome-driven, performance-tracking approach that will hold states and metropolitan planning organizations accountable for improving the conditions and performance of their transportation assets. It will therefore increase agency attentiveness to these vital issues. Transportation Asset Management (AM) is a strategic and systematic process of operating, maintaining, upgrading, and expanding physical assets effectively throughout their life cycle. It focuses on business and engineering practices for resource allocation and utilization, with the objective of better decision making based on quality information and well-defined objectives. Advancing AM capabilities and integrating these capabilities across an organization's business units requires self-assessment, alignment, goal setting, and support. This synthesis of transportation asset management practice among state highway agencies will be a timely resource for agencies to identify their current state of practice and determine where they will direct their AM efforts. This synthesis is based on two separate surveys, with additional input from practitioners. The initial survey requested that participants conduct a self-assessment to characterize their agency's AM practices....The self-assessment results reflect current and future (5-year) business practices and the agencies' institutional, organizational, financial, and IT environments. This survey yielded 18 DOT participant responses (see Appendix D). Based on the results of the initial survey, and input from the Topic Panel, a second survey was designed to capture the state of practice and forward looking expectations (for the next 3 to 5 years) among state DOTs. Forty-three agencies participated in this second survey."--p. 1.

Federal Aid and Non Federal Aid roads are the most important assets for every local government. Collecting data, analyzing and proposing a practical and cost-effective work plan has been the goal of local agencies. Implementing pavement management process can help local agencies to make the best decision regarding road investments. In this study, pavement management is comprised of two main parts. At the network level, the macroscopic model is adopted where each decision variables represents a specific proportion of the asset network. For each decision variable, future condition prediction models are developed. An annual budget scenario can be analyzed with the flexibility to vary the treatment unit costs, allowable treatments, treatment average life and the span of the analysis period. At the project level, the microscopic model is implemented to generate a detailed work plan based on the results from network level part. Also culverts are of the crucial parts of transportation assets and their failures can jeopardize the ecosystem and result in accidents. Inspecting and developing a management system can help agencies to better understand the current and future condition. In this thesis for a given budget level, the corresponding performance of the asset network is determined using the linear programming optimization with the objective of average network condition maximization. The optimization model consists of an asset deterioration model. The deterioration rates are predicted based on the historical condition data using the Markov model. Then, the results from linear programming used to provide users with a detailed work plan.

Aims to encourage transportation agencies to address strategic questions as they confront the task of managing the surface transportation system. Drawn form both national and international knowledge and experience, it provides guidance to State Department of Transportation (DOT) decision makers, as well as county and municipal transportation agencies, to assist them in realizing the most from financial resources now and into the future, preserving highway assets, and providing the service expected by customers. Divided into two parts, Part one focuses on leadership and goal and objective setintg, while Part two is more technically oriented. Appendices include work sheets and case studies.
