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.

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.

This synthesis report will be of interest to various transportation-related groups around the world involved in collecting positional data with global positioning systems (GPSs) and integrating these data into existing geographic information systems (GISs). The focus is on the major issues that these groups are facing with data collection, data smoothing, and data integration, including identification of inaccurate, bad, or missing data points, and the lack of standard map matching algorithms. It addresses the fact that each application uses its own GPS equipment, GIS database, and internal set of GPS data processing rules, and that information sharing and coordination has been limited. This synthesis was accomplished through a literature review and a survey of the state-of-the-practice activities in GPS data collection, data smoothing, and map matching. This report of the Transportation Research Board provides information on the potential and the problems of integrating GPS data with data from GIS to provide departments of transportation with a powerful set of planning and programming tools. It addresses existing data standards and their applicability, procedures for processing and integrating spatial data, map matching algorithms and protocols, and recent developments in positioning, including cellular technology. The synthesis identifies a six-step method designed to help improve the quality of maps and reduce the severity of problems associated with GPS-GIS integration.

Assessment and Rehabilitation of Existing Culverts
Author: Wyant, D C | Size: 3.35 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2002 | pages: 80 | ISBN: 0309069203
This synthesis report will be of interest to department of transportation, county, and municipal engineers, as well as to other transportation professionals who are concerned with the condition and maintenance of buried culverts and storm sewers. Its objective is to determine the state of the practice of pipe assessment, the selection of appropriate repair or rehabilitation methods, and the management aspects of a pipe program. This report provides information on plastic, concrete, and metal pipes and their appurtenances, including inlets, manholes, joints, and headwalls. It also provides information on how transportation agencies have incorporated pipe assessment and corrective work (repair or rehabilitation) into a pipe management system and eventually into the larger transportation management system. Rehabilitation specifications and methods of field report are presented as well. The study presents what management systems and methods are being used by transportation agencies to predict the service life of pipes. This report of the Transportation Research Board contains information derived from survey responses from 39 state transportation agencies (including Guam and Puerto Rico), 21 federal agencies, and 15 localities, including county road commissions, public works departments, and county engineering departments. In addition, a literature search was conducted to determine the current state of the practice.

This report presents the state of the practice about commonly used expansion joint systems in bridges. Specifically, it summarizes performance data for each system type and contains examples of selection criteria and design guidelines. The report will be of interest to bridge engineers and designers, and any agencies responsible for bridge operation and maintenance. Topics covered include a review of the current practice, expansion joint types and features, selection criteria and design guidelines, provisions to test joint seal watertightness, and lessons for maximizing the service life of joint systems. Information in support of this study came from the responses to a survey questionnaire from 34 states and 10 Canadian provinces. Questions addressed design procedures, use and experience, construction practices, maintenance and rehabilitation, and problems. Supplemental information relating to bridge deck selection and design criteria was provided by several states. Portions of the joint system guidelines of these states, which are considered important for purposes of comparison, are contained in the report.

This synthesis report provides information on previous and current design and construction practices used to improve the performance of bridge decks. The primary focus is on North American practice for cast-in-place (full depth and partial depth), reinforced concrete bridge decks on steel beams, concrete I- and T-beams, or concrete box beams. Information was obtained on the following topics: factors that contribute to the durability of concrete bridge decks; performance of various types of deck protection strategies; lessons learned and the current state of the practice in design, construction, and maintenance of concrete bridge decks; available comparative analysis of the effects of using different methods and materials; specific reports of successes and failures; sample design and construction specifications; available life-cycle cost information; research in progress; and suggestions for future study. This synthesis report combines information obtained from survey responses from bridge owners and from a literature review.
