TRB’s National Cooperative Highway Research Program (NCHRP) Report 716: Travel Demand Forecasting: Parameters and Techniques provides guidelines on travel demand forecasting procedures and their application for helping to solve common transportation problems.
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.
"This [i.e. The] purpose of this guidebook is to help organizations improve the development, implementation, and management of their transportation plans and programs. By adding an element of performance measurement and monitoring to existing transportation planning processes, agencies can obtain better information about the performance of their existing programs and services. Performance-based planning provides a process and tools to identify and assess alternative programs, projects, and services with respect to overall transportation plan goals and objectives."--Ch. 1. Overview, p. 3.
Federal planning legislation and regulations now mandate that state departments of transportation and metropolitan planning organizations consider the needs of freight when planning and programming transportation investments. While there are standard techniques used to forecast the movement of people, less attention has been paid to forecasting freight movements, and there are consequently fewer standardized techniques that state and local agencies can adapt to their local situation. This Toolkit is designed to provide transportation planners with the information they need to prepare forecasts of freight transportation by highlighting techniques successfully developed by state agencies across the country.
"TRB's National Cooperative Freight Research Program (NCFRP) Report 26: Guidebook for Developing Subnational Commodity Flow Data explores how state departments of transportation and other subnational agencies can obtain and compile commodity flow data. The Guidebook contains descriptions of existing public and private commodity flow data; standard procedures for compiling local, regional, state, and corridor databases from these commodity flow data sources; procedures and methodologies for conducting subnational commodity flow surveys and studies; and methods for using commodity flow data in local, regional, state, and corridor practice. In addition to the Guidebook, two subtask reports from NCFRP Project 20--Review of Subnational Commodity Flow Data Development Efforts and National Freight-Related Data Sets and Demonstration of Application of Establishment Survey--are available only in electronic format."--Publisher's description.
