The method used to prepare a traffic forecast needs to relate to the type of projects for which the forecast is prepared. This report describes the various types of projects for which the Texas Department of Transportation uses traffic forecast date. For each project category, the type of traffic forecast data needed to perform the required analyses is identified and the appropriate forecasting procedure and level of forecast accuracy that can be expected is described. The project categories and forecasting requirements discussed include urban transportation planning; feasibility studies; advanced planning; environmental documentation; and geometric, signalized intersection, pavement, and bridge design.
