HIGHWAY NOISE. A DESIGN GUIDE FOR PREDICTION AND CONTROL

A description of motor vehicle noise sources and the potential for their control is provided. The report presents an overview of the suggested noise prediction methodology, which is a four step process that includes approximating noise impacts using a nomograph procedure to determine noise levels associated with given traffic and site characteristics; refining these predictions by more accurate representation of design parameters and use of a computer program that is able to plot as well as calculate noise impact; introducing appropriate noise-control options and evaluate them, using a noise barrier nomograph solution; lastly, selected options are fully evaluated using the computer program. A comprehensive review of noise control measures, including not only barriers but also other alternatives, such as grade separation, decks, and right-of-way modifications. Procedures for measuring background noise levels, an evaluation of an environmental impact assessment procedure, and a user's manual describing and listing the computer programs for predicting and plotting highway noise levels are also included.
