In this paper, a selection of updated data on a wide variety of statistics pertaining to urban travel demand, and how they have beenintegrated into the umta report, "characteristics of urban transportation demand an update, " are discussed. This report presents a compilation of almost exclusively post-1970 data on travel demand for all major urban modes. It is designed to be used by transportation planners and analysts as a source of data to check the validity and reasonableness of local forecasts developed from either conventional or emerging planning and modeling techniques, or as a cross-check on the similarity of travel statistics from one locality to another. Certain data also may be used as default values for modeling purposes, when such information is not available locally or would require newor extensive data collection efforts. Another application is in examining how key statistics have changed over time and transferring these changes from one area to another. Much of the information contained in the report was obtained from reports, documents, and memoranda produced by or for each study area contacted. A main criterion of the study was that the information collected be based on surveys, measurements, counts, and so forth, and not be synthesized results form analytical modeling efforts. Many source documents have not been circulated widely, adding to the usefulness of the data contained in this report.
