TRB Special Report 288, Metropolitan Travel Forecasting: Current Practice and Future Direction, examines metropolitan travel forecasting models that provide public officials with information to inform decisions on major transportation system investments and policies. The report explores what improvements may be needed to the models and how federal, state, and local agencies can achieve them. According to the committee that produced the report, travel forecasting models in current use are not adequate for many of today's necessary planning and regulatory uses.

Two conferences on Refocusing Transportation Planning for the 21st Century were held in 1999 following passage of the Transportation Equity Act for the 21st Century (TEA-21). The first conference focused on the identification of key trends, issues, and general areas of research. The results of Conference I, which produced stand-alone products, were used as input for Conference II. The second conference had the specific objective of producing research problem statements. Its mission was to review the results of the first conference by developing these statements. Conference II produced a number of detailed research statements that form the basis for the National Agenda for Transportation Planning Research. The proceedings of both conferences are presented in this report.
Conference participants sought to identify gaps in the data and analytic tools needed to support economic analysis as related to transportation investment and to develop research proposals designed to fill those gaps. The opening day of the conference featured presentations by economists, transportation analysts, and policy makers on the theory and practice of economic analysis and its usefulness to decision makers. The second and third days of the conference revolved around participatory workshops. Six separate working groups deliberated over three questions: (1) What is the appropriate level of investment in transportation to encourage economic health? (2) How should projects be prioritized within a multimodal transportation program? (3) How much revenue is likely to flow from user charges, tolls, and other sources? At the conclusion of its deliberations, each working group developed a list of research proposals, which it then presented to the conference as a whole.
The U.S. census, conducted every 10 years since 1790, faces dramatic new challenges as the country begins its third century. Critics of the 1990 census cited problems of increasingly high costs, continued racial differences in counting the population, and declining public confidence. This volume provides a major review of the traditional U.S. census. Starting from the most basic questions of how data are used and whether they are needed, the volume examines the data that future censuses should provide. It evaluates several radical proposals that have been made for changing the census, as well as other proposals for redesigning the year 2000 census. The book also considers in detail the much-criticized long form, the role of race and ethnic data, and the need for and ways to obtain small-area data between censuses.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 358: Statewide Travel Forecasting Models examines statewide travel forecasting models designed to address planning needs and provide forecasts for statewide transportation, including passenger vehicle and freight movements. The report explores the types and purposes of models being used, integration of state and urban models, data requirements, computer needs, resources (including time, funding, training, and staff), limitations, and overall benefits. The report includes five case studies, two that focus on passenger components, two on freight components, and one on both passenger and freight.
TRB Special Report 277 - Measuring Personal Travel and Goods Movement recommends a series of actions the U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) should take to render its flagship surveys -- the National Household Travel Survey (NHTS) and the Commodity Flow Survey (CFS) -- more effective in meeting the needs of a broad spectrum of data users. The report also recommends approaches BTS and its survey partners should adopt to develop more effective survey methods and address institutional issues affecting survey stability and quality.

Describe how transit agencies, metropolitan planning organizations, and state DOTs can act today to initiate or expand their analytical tools for integrated land use-transportation planning. The Guidelines are intended for the general reader having an interest in the effects of transit on land use. The Guidelines describe currently available integrated models, the characteristics of an "ideal" integrated model, and steps that a planning organization should take in order to support and expand such modeling capability.

TRB Special Report 298: Driving and the Built Environment: Effects of Compact Development on Motorized Travel, Energy Use, and CO2 Emissions examines the relationship between land development patterns and vehicle miles traveled (VMT) in the United States to assess whether petroleum use, and by extension greenhouse gas (GHG) emissions, could be reduced by changes in the design of development patterns. The report estimates the contributions that changes in residential and mixed-use development patterns and transit investments could make in reducing VMT by 2030 and 2050, and the impact this could have in meeting future transportation-related GHG reduction goals.
