PREDICTING SWEDISH TRAFFIC NOISE USING A MODIFIED AUSTRALIAN MODEL. ACOUSTICS IN THE EIGHTIES, AUSTRALIAN ACOUSTICAL SOCIETY ANNUAL CONFERENCE, HOBART, 12-13 NOVEMBER 1987

In order to estimate on regional or national scales historical changes in road traffic noise exposure, as well as future predicted exposures, it is wise to use a computer model. This paper describes the adaptation to Swedish conditions, and improvement, of a model originally developed to predict traffic noise in Sydney over the years 1965 to 2015. In most computer models there is a conflict between striving for rigorous accuracy on the one hand and keeping the data input requirements and model's complexity down to manageable proportions on the other hand; this model strikes a good balance and the trade offs in its design and adaptation are discussed. Results are presented of the application of this model to three areas in Sweden representing fairly well the cases of rural, small town and city areas. It seems possible to restore the noise environment by the year 2000 to that of the early 1960s but only if a number of measures are used together such as EEC vehicle noise standards in 1990, bypass roads and low noise road surfaces. The model was validated in that its results gave fairly good agreement with manual calculations and previously published work. (Author/TRRL)
