Since freight planning on a statewide basis is in the early stages of development, a basic core of knowledge about goods transport must be developed and existing freight data source material must be identified. This project determined the data requirements for statewide freight transportation planning and prepared a manual on how the states may obtain primary and secondary data. The result was an extensive catalog of freight data sources for use by state and regional planners. Procedures and techniques for obtaining primary and secondary data are described. Five types of planning activities and analysis techniques were examined to determine specific data requirements: demand forecasting, mode choice analyses, network analysis, economic evaluation, and impact estimation. States are not advised to conduct their own primary surveys except in cases where limited, specialized information is required that is not available from any other source. States should generally rely on existing secondary data for freight transportation system planning purposes. The specific methods presented in the user manual were taken from previous planning studies and can be successfully applied by other agencies.
