Two major studies formed the basis for a theory of traffic noise from which a simulation model was built, and computers were used to describe the noise of different highway situations. The two studies basic to the simulation model involved comparing various measures of sound, and deciding upon a simple, yet satisfactory physical measure of the level of sound, and then measuring noise produced by various kinds and classes of vehicles.

Various methods of assessing noise, loudness, and noise annoyance are reviewed and explained; sources, types, and intensities of traffic noise are noted; typical means of abatement and attenuation are described; design criteria for various land uses ranging from low-density to industrial are suggested and compared with the results of previous BBN and British systems for predicting annoyance and complaint; and a design guide for predicting traffic noise, capable of being programmed for batch and on-line computer applications, is presented in form suitable for use as a working tool. A flow diagram describes the interrelationships of elements in the traffic noise prediction methodology, and each element is discussed in detail in the text. The text is presented of a tape recording that takes the listener through a series of traffic situations, with such variables as traffic distance, flow velocity, distance, outdoors and indoors, and presence or absence of absorbers and attenuators.
