This report provides detailed descriptions of manual techniques for use in each aspect of travel demand estimation, i.e., trip generation, trip distribution, modal choice, auto occupancy, time-of-day distribution, Traffic assignment, capacity analysis, and development density versus highway spacing relationships. Numerous charts, tables, and nomographs are included to simplify each analysis step. Data requirements are also reduced by making maximum use of transferable parameters developed from other studies and urban areas. Three scenario applications of the manual techniques are included to illustrate the potential usefulness of the various analysis techniques. Much of the information contained in the report is also applicable to computer analysis. The presentation of the procedures is structured to allow their utilization by transportation planners with various levels of experience. A companion document, NCHRP Report 186, describes and evaluates other manual and computer methodologies that are available. (Author/publisher)
