BRITISH AND AMERICAN TRAFFIC NOISE PREDICTION METHODS: THEIR APPLICATION TO SEVERAL URBAN SITES IN BRITAIN

Recent legislation requires that highway authorities, in certain cases, carry out sound insulation works when the 10-hour L10 noise level exceeds a specified value. In this paper the results are presented of a comparison experiment between the 'British method' of noise prediction, which has been developed by the building research station, and the 'American method' for the prediction of traffic noise. Three sites were chosen in the city of Bradford Metropolitan District for investigation and their characteristics and the experimental procedure are described. The 'American method' of noise prediction is briefly described and a prediction table for the hourly L10 level at one site is given. A comparison between the measured 18-hour L10 index at all three sites and the results predicted by the 'British method' show excellent agreement. The 'American method', however, gives predictions which are far too high. This may be due to cars and heavy vehicles being considered separately in this method with the result that the contribution to the index from heavy vehicles dominates even at small flows. However, the greater flexibility of the 'American method' means that its modification to apply to British conditions would make it a useful prediction tool. /TRRL/
