COMPARISON OF HIGHWAY NOISE PREDICTION MODELS

A review and comparison has been conducted of three highway noise prediction models: NCHRP, TSC, and Wyle. The first two are those approved by the Federal Highway Administration; the third was developed for EPA. The elements comprising each model are analyzed in detail, including basic formulation, vehicle noise levels, propagation, treatment of various road geometries, and shielding by barriers. Significant differences among the models were found. A series of charts is presented whereby differences among the models may be estimated for particular input data. Comparison between measured roadside levels and predictions from the three models are also presented.
