Transportation asset management is a data-intensive process and data integration is a fundamental component to improve integrated decision making. The evolution of geographic information systems and spatial technologies is providing powerful mechanisms for developing asset management decision-making products. However, many agencies are struggling with the development of these spatial products on an enterprise basis. The Transportation Research Board (TRB) Transportation Asset Management Committee (ABC40) and Spatial Data and Information Science Committee (ABJ60) hosted a peer exchange to investigate state and local agency applications of spatial technologies for asset management activities and to identify ongoing issues and research directions. Six state and local transportation agencies were selected based on their leadership and progress in the application of spatial technologies towards asset management. These six agencies were the Alaska Department of Transportation and Public Facilities; the City of Edmonton, Alberta, Canada; the Kansas Department of Transportation; the New York State Department of Transportation; the New York State Thruway Authority; and the North Carolina Department of Transportation. Prior to the peer exchange, agency participants completed an extensive questionnaire on their uses of spatial technologies, their history of implementation, and perceived benefits and issues. The peer exchange participants focused on three major issue areas in moving spatial technology applications to the next level: managing change, data integration, and communication. Upon a thorough discussion of these issues, the peer participants identified research to address three areas of interest: temporal issues, symbology, and data and visualization models. The roles of national organizations in sharing best practices and in promoting standards and open data architectures were also discussed. This circular contains the presentations of the perspectives of the six agencies, a summary of agency responses to the questionnaire, and a summary of the major issues and research directions for the future.

This circular includes six articles that explore five general artificial intelligence (AI) areas including knowledge-based systems, neural networks, fuzzy sets, genetic algorithms, and agent-based models. The circular is designed to serve as an informational resource for transportation practitioners and managers with respect to AI tools within these general areas. Each article details the types of problems to which the paradigm is best suited, its strengths and weaknesses, example applications, and guidelines for its application.

The design and construction of the Interstate Highway System (IHS) is one of the most significant and costly public works projects in the history of the United States. Given that the 50th anniversary of the enabling legislation for the IHS occurred during 2006, it is appropriate to reflect on the performance of the system, specifically its pavements. The American Association of State Highway Officials (AASHO) Road Test was authorized by the IHS legislation and occurred about 5 years after the legislation was enabled. It is also assessed in light of what we know today. Reflections on the performance of IHS pavements and lessons learned from the AASHO Road Test were presented in two sessions organized by the Transportation Research Board (TRB) Pavement Management section (AFD00) for the 2006 TRB Annual Meeting. The two sessions were Session 353: Pavement Lessons from the 50-Year-Old Interstate System and Session 470: Views on AASHO Road Test after 50 Years. Each of the presenters was requested to prepare a manuscript for inclusion in this circular. They are included as six papers, not necessarily in the order they were presented in the sessions.

TRB’s Transportation Research Circular E-C128 includes papers that were presented at the 10th International Conference on Bridge and Structure Management held on October 20-22, 2008, in Buffalo, New York. The conference brought together practitioners, administrators, and researchers from around the world to exchange information on the development, implementation, and utilization of effective bridge and structure management practices. Issues addressed by papers presented at the meeting included design and implementation of bridge management systems; application of bridge management in transportation agencies; bridge preservation, maintenance, and deterioration rates; application of prioritization and optimization routines; and more.

This synthesis report summarizes the current practice and research on statistical methods in highway safety analysis. This synthesis report will be of interest to individuals with state transportation departments and with district and local agencies involved directly with safety analysis in highway jurisdictions, as well as to contractors undertaking safety analysis and associated work for them. Highway safety analysts in many countries around the world might also find this synthesis of interest. The focus of this report is on the type of safety analysis required to support traditional engineering functions, such as the identification of hazardous locations and the development and evaluation of countermeasures. Analyses related specifically to driver and vehicle safety are not covered, but some statistical methods used in these areas are of relevance and are summarized where appropriate. This synthesis may benefit analysts working in these other areas as well.
