13 2018 Annual Repor t RESEARCH PRODUCTS Disseminating Research and Documenting Success Dissemination of research findings to practitioners is a primary objective of the entire NCHRP research process. Publication of the final report or other deliverables is a key means of dissemination. NCHRP research findings are published in a number of series, which are listed in Table 1 of this Annual Report. Quantities for these series published over the past five years are shown in Exhibit 3. Some NCHRP publications produced this year are: NCHRP Research Report 868: Cell Phone Location Data for Travel Behavior Analysis presents guidelines for transportation planners and travel modelers for evaluating the extent to which cell phone location data and associated products accurately depict travel. The report identifies whether and how these extensive data resources can be used to improve understanding of travel characteristics and the ability to model travel patterns and behavior more effectively. The report also supports the evaluation of the strengths and weaknesses of anonymized call detail record locations from cell phone data. (Project 08-95) NCHRP Research Report 884: Guidelines for Managing Geotechnical Risks in DesignâBuild Projects provides guidelines for the implementation of geotechnical risk management measures for designâbuild project delivery. The guidelines offer five strategies for aligning a transportation agency and its designâbuilderâs perception of geotechnical risk, as well as 25 geotechnical risk management tools that can be used to implement the strategies on typical designâbuild projects. This report helps to identify and evaluate opportunities to measurably reduce the levels of geotechnical uncertainty before contract award. (Project 24-44) NCHRP Synthesis 521: Investment Prioritization Methods for Low-Volume Roads documents current practices used by transportation agencies to make investment decisions about low-volume roads. This publication also addresses the challenges that decision makers may face to communicate the value of such investments to stakeholders in an era of limited funds and constantly changing demands on the transportation system. (Project 20-05/Topic 48-07) NCHRP Web-Only Document 242: Recommended AASHTO Guide Specifications for ABC Design and Construction documents the results of a synthesis of past research regarding accelerated bridge construction (ABC), leading to the development of guide specifications for ABC. Part 1 of the report includes design specifications for ABC. Part 2 of the report includes construction specifications. All current ABC technologies are covered in the specifications, and the outline of the specifications lends itself to the addition of future technologies. (Project 12-102)

Print copies are mailed to the CEOs of state DOTs, AASHTO staff, panel members, the contractor, and the following individuals and organizations: â¢ TRB members who have chosen to receive publications in the particular subject area of the report â¢ About 100 libraries â¢ TRB representatives in the state DOTs â¢ Numerous educational institutions â¢ Liaison representatives from industry and transportation organizations in other countries â¢ Relevant TRB panels and committees The number of printed reports has been declining, with more people accessing reports online. NCHRP subprograms Several âsubprogramsâ are carried out within NCHRP. Results may be published in hard copy, delivered in the form of internal reports and presentations, published on the TRB website, or made available upon request. Synthesis of Information Related to Highway Problems (Project 20-05) Administrators, practicing engineers, and researchers continually face problems on which much information already exists, either in documented form or in terms of undocumented experience and practice. Unfortunately, this information is often fragmented and scattered, and therefore overlooked. The NCHRP Synthesis series aims to remedy this lack of awareness of existing solutions by assembling and organizing relevant information, practices, and research for particular highway problems. 4 Nat i on al C o perat ive Highway Research Program
15 2018 Annual Repor t Legal Problems Arising out of Highway Programs (Project 20-06) State DOTs have an interest in evaluating the operating practices, administrative procedures, and legal issues associated with planning, design, and construction of transportation projects. Individual state legal experiences need to be compared and made available for possible wider application. This research identifies and evaluates legal options for DOTs, which facilitates the handling of both immediate and long-range needs. Research for AASHTO and State DOT Leadership (Project 20-24) NCHRP conducts focused research that addresses and responds to the evolving challenges facing state DOT decision makers. Reports from this project deliver timely information on topics including asset management, innovative financing and contracting, performance measures, and e-business, as well as emerging topics such as connected automated vehicles and workforce development. NCHRP IDEA Program (Project 20-30) The Innovations Deserving Exploratory Analysis (IDEA) program funds research into promising but unproven innovations for highway design and construction, materials, operations, maintenance, and other areas of highway systems. A progress report that describes current and completed projects is published annually. Of the 182 projects completed to date, 33 projects have been successfully implemented. That results in 18 percent of products funded by the IDEA program successfully implemented. International Highway Research and Technology (Project 20-36) The NCHRP International Highway Research and Technology program provides a coordinated approach to international information sharing and technology exchange. The program helps to fund U.S. participation in international activities that identify innovative technology and successful policies and practices from around the globe. Domestic Scan Program (Project 20-68) The NCHRP Domestic Scan Program identifies innovative practices of high- performing transportation agencies that could be beneficially adopted by other interested agencies. The purpose of each scan and of the program as a whole is to facilitate information sharing and technology exchange among the states and other transportation agencies and to identify actionable items of common interest. âIn the [DallasâFort Worth] region we use the principles outlined in NCHRP Report 694: Evaluation and Performance Management of Congestion Pricing Projects as reference for all ongoing managed lane activities.â â Daniel Lamers, North Central Texas Council of Governments
