The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president. The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. C. D. Mote, Jr., is president. The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president. The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine. Learn more about the National Academies of Sciences, Engineering, and Medicine at www.national-academies.org. The Transportation Research Board is one of seven major programs of the National Academies of Sciences, Engineering, and Medicine. The mission of the Transportation Research Board is to increase the benefits that transportation contributes to society by providing leadership in transportation innovation and progress through research and information exchange, conducted within a setting that is objective, interdisciplinary, and multimodal. The Board’s varied committees, task forces, and panels annually engage about 7,000 engineers, scientists, and other transportation researchers and practitioners from the public and private sectors and academia, all of whom contribute their expertise in the public interest. The program is supported by state transportation departments, federal agencies including the component administrations of the U.S. Department of Transportation, and other organizations and individuals interested in the development of transportation. Learn more about the Transportation Research Board at www.TRB.org.

Consensus Study Reports published by the National Academies of Sciences, Engineering, and Medicine document the evidence-based consensus on the study’s statement of task by an authoring committee of experts. Reports typically include findings, conclusions, and recommendations based on information gathered by the committee and the committee’s deliberations. Each report has been subjected to a rigorous and independent peer-review process and it represents the position of the National Academies on the statement of task. Proceedings published by the National Academies of Sciences, Engineering, and Medicine chronicle the presentations and discussions at a workshop, symposium, or other event convened by the National Academies. The statements and opinions contained in proceedings are those of the participants and are not endorsed by other participants, the planning committee, or the National Academies.

ix Acknowledgments These conference proceedings were compiled with the help of the conference chair, the conference planning committee, the track leads, the moderators, and the reporters. Katie Zimmerman of Applied Pavement Technology, Inc., served as the conference rapporteur and prepared these proceedings from materials provided by session reporters, presentations submitted by presenters, and her own notes. These proceedings are a compilation of the presentations and a factual summary of the ensuing discussions at the event. The conference planning committee was responsible solely for organizing the conference, identifying speakers, and activities during the event. The views contained in the report are those of individual participants and do not necessarily represent the views of all participants, the planning committee, the Transportation Research Board (TRB), or the National Academies of Sciences, Engineering, and Medicine. These proceedings were reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise in accordance with procedures approved by the National Academies’ Report Review Committee. The purposes of this independent review are to provide candid and critical comments that will assist the institution in making the published report as sound as possible and to ensure that the report meets institutional standards for objectivity, evidence, and responsiveness to the project charge. The review comments and draft manuscript remain confidential to protect the integrity of the process. TRB thanks the following individuals for their review of these proceedings: Emily Burns, Trish Hendren, Robert Peskin, and Steve Wilcox. Although the reviewers listed above provided many constructive comments and suggestions, they did not see the final draft of the proceedings before its release. The review of these proceedings was overseen by Susan Hanson of Clark University (emerita). Appointed by the National Academies, she was responsible for making certain that an independent examination of the proceedings was performed in accordance with established procedures and that all review comments were carefully considered. Responsibility for the final content rests entirely with the authors and the institution.

TRB’s Conference Proceedings on the Web 25: Proceedings of the 12th National Conference on Transportation Asset Management is a compilation of the presentations and summary of the ensuing discussions at a July 14–15, 2018, meeting held in San Diego, California.

During the meeting, attendees explored the development of integrated investment decisions within an uncertain financial planning environment; and the development and implementation of data systems, best practices in data collection, methods used to estimate the expected return on investment, and strategies for communicating results.

The meeting also addressed best practices and lessons learned from Transit Asset Management (TAM) implementation efforts; offered a forum for the sharing of organizational transformations and key strategies for building an effective TAM workforce; and explored the development and maturation of agency transportation asset management plans (TAMPs).

The structure of the program also ensured that transit and risk and resilience were included in the areas of exploration during the meeting.
