Managing Contract Research, NCHRP Synthesis Report 231
This report explores the state of the practice for managing contract research programs.
Putting Research into Practice: A Synopsis of Successful Strategies and Case Histories
NCHRP Research Results Digest 225: This synopsis summarizes implementation practices leading to the successful and timely application of research findings, and illustrates the use of these practices in several case studies drawn from the research findings.
Facilitating the implementation of Research Findings
NCHRP Report 382: This report contains the findings of a study that was performed to identify the factors affecting implementation of research results, to delineate strategies that are expected to promote this implementation, and to recommend research to test the more viable strategies for putting transportation research results into practice. The report describes the research and provides recommendations to help state highway and transportation agencies and other highway organizations pursue more effective implementation of research results. This report should be of interest to decision makers and agency personnel responsible for research planning and administration.
Effective Experiment Design and Data Analysis in Transportation Research (NCHRP Report 727)
This report describes the factors that should be considered in designing experiments and presents 21 typical transportation examples illustrating the experiment design process, including selection of appropriate statistical tests. The examples encompass a wide range of transportation disciplines and statistical methods. This report will be very beneficial to anyone with limited research experience needing to answer a question based on data (e.g., presenting ozone concentrations in a region, determining whether a contractor?s quality
assurance/quality control procedures are adequate, estimating the effect of automated enforcement on speeds, monitoring trends in the condition of bridge superstructures, developing
a user survey to determine the impact of transit fare changes). The report is a companion to NCHRP CD-22, Scientific Approaches to Transportation Research, Volumes 1 and 2,
which were developed in NCHRP Project 20-45 and present detailed information on statistical methods. NCHRP CD-22 is available at http://www.trb.org/Main/Blurbs/152122.aspx.
Scientific Approaches to Transportation Research
An Overview of National Transportation Research
This summary was produced by the AASHTO RAC Education and Training Task Group and was adapted from a report titled “Transportation Research: Value to the Nation?Value to the States,” a product of NCHRP 20-80(1), which was prepared by CTC & Associates LLC.
Long-Range Strategic Issues Facing the Transportation Industry
The transportation industry will face new and emerging challenges in the future that will dramatically reshape transportation priorities and needs. The American Association of State Highway and Transportation Officials (AASHTO) recognizes that research can help ensure that transportation practitioners are equipped to deal with future challenges facing the industry over the next 30 to 40 years. These challenges may derive from the impacts of major global trends, such as climate change, changes in the cost of fuels, and new technology, and from domestic trends, such as changing demographics and lifestyle expectations, changes in land use patterns, and limitations in current transportation finance methods. AASHTO has allocated $5,000,000 to examine longer-term strategic issues both global and domestic that will likely affect state departments of transportation (DOTs) and directed $1,000,000 to each of the following projects: (1) Potential Changes in Goods Movement and Freight in Changing Economic Systems and Demand; (2) Framework for Advance Adoption of New Technologies to Improve System Performance; (3) Approaches to Enhance Preservation, Maintenance, and Renewal of Highway Infrastructure; (4) Effects of Changing Transportation Energy Supplies and Alternative Fuel Sources on Transportation; and (5) Potential Impacts of Climate Change on Transportation Infrastructure and Operations, and Adaptation Approaches.
The 2008 report, “Long-Range Strategic Issues Facing the Transportation Industry” prepared by ICF International of Fairfax, Virginia, presents a framework for this effort and identifies future issues and trends, which may create new challenges for the transportation industry, based on a literature scan of work conducted by futurists, demographers, economists, and other experts. Research conducted for this project will focus on a longer timeframe (30 to 40 years) than is typically examined in NCHRP projects. Although some of the future challenges facing the transportation industry are emerging today, the goal of this research is to look beyond and focus on the longer term consequences.
Independently, and in combination, these trends may have significant implications for the transportation system. Many of the trends and forces affecting the future are interrelated and the crosscutting linkages between trends and forces that will affect transportation in the future will be examined. Research conducted for this project should consider the following two goals: (1) anticipate the future issues that may be approaching so that transportation agencies are better prepared to respond to new and emerging challenges; and (2) explore visions of what the future should look like, so that transportation agencies can help shape the future through their decision-making.

Strategic Issues Facing Transportation, Volume 4: Sustainability as an Organizing Principle for Transportation Agencies
TRB’s National Cooperative Highway Research Program Report 750: Strategic Issues Facing Transportation, Volume 4: Sustainability as an Organizing Principle for Transportation Agencies includes an analytical framework and implementation approaches designed to assist state departments of transportation and other transportation agencies evaluate their current and future capacity to support a sustainable society by delivering transportation solutions in a rapidly changing social, economic, and environmental context in the next 30 to 50 years.
NCHRP Report 750, Volume 4 is the fourth in a series of reports being produced by NCHRP Project 20-83: Long-Range Strategic Issues Facing the Transportation Industry. Major trends affecting the future of the United States and the world will dramatically reshape transportation priorities and needs. The American Association of State Highway and Transportation Officials (AASHTO) established the NCHRP Project 20-83 research series to examine global and domestic long-range strategic issues and their implications for state departments of transportation (DOTs); AASHTO’s aim for the research series is to help prepare the DOTs for the challenges and benefits created by these trends.
Other volumes in this series currently available include:
• NCHRP Report 750: Strategic Issues Facing Transportation, Volume 1: Scenario Planning for Freight Transportation Infrastructure Investment
• NCHRP Report 750: Strategic Issues Facing Transportation, Volume 2: Climate Change, Extreme Weather Events, and the Highway System: Practitioner’s Guide and Research Report

Strategic Issues Facing Transportation, Volume 6: The Effects of Socio-Demographics on Future Travel Demand
TRB’s National Cooperative Highway Research Program (NCHRP) Report 750: Strategic Issues Facing Transportation, Volume 6: The Effects of Socio-Demographics on Future Travel Demand presents the results of research on how socio-demographic changes over the next 30 to 50 years may impact travel demand at the regional level. It is accompanied by a software tool, Impacts 2050, designed to support the long-term planning activities of transportation agencies.
The print version of the report contains a CD-ROM that includes Impacts 2050, the software user’s guide, a PowerPoint presentation about the research, and the research brief. The CD-ROM is also available for download from TRB’s website as an ISO image. Links to the ISO image and instructions for burning a CD-ROM from an ISO image are provided below.
