This is an informational report of the Institute of Transportation Engineers that summarizes the results of a survey of state and provincial highway agencies designed to identify procedures used to predict horizon-year traffic volumes on specified highway segments. It was found that a variety of procedures are used, depending on the location of the project (rural or urban). The traditional 4-step urban modeling procedure is used in many urban areas, whereas trendlining of traffic counts is used in rural areas. This report describes the questionnaire design, presents questionnaire results, and summarizes the conclusions of the study. It was found that most agencies are involved in research and refinement activities designed to improve current procedures, as well as in adopting microcomputer techniques into their practice.
