This report presents the FHWA method for predicting noise generated by constant speed highway traffic. The report is intended to be a user's manual as well as a reference document detailing the development, use, and limitations of the prediction method. In the main body of the report, the prediction procedure is presented in a step-by-step fashion and includes numerous example problems designed to highlight important concepts and features. For those interested in the theoretical development of the model, an extremely detailed derivation is presented in the appendices. The basis of the model is the equivalent sound level, Leq, although an adjustment for conversion to L10 is provided. The method incorporates three classes of vehicles--automobiles, medium trucks, and heavy trucks. Adjustment for absorptive ground covers and finite length barriers are also included. Certain special topics such as nonuniform highway sites and determination of equivalent day-night levels, Ldn, are also included.
