Abstract

This paper introduces the study on prediction accuracy of the ASJ RTN-Model 2018, as a part of the series of five papers which has same main title in this congress, on behalf of the research committee on road traffic noise in the Acoustical Society of Japan. It is very important to examine the prediction accuracy of the new model, because some assumptions are included in modeling the source power level of each type of vehicles and in simplifying the calculation of noise propagation. Some examination of the correspondence between the predicted values and measured traffic noise levels are introduced in this paper. The accuracy of the method of prediction for noise behind building complex are also examined. The measured values were obtained recently in Japan on flat and strait section of general roads and on expressways. This paper also introduces the examination on assumed causes of errors that are thought to be important in considering prediction accuracy, such as the condition setting of hypothetical traffic lanes, vehicle type classification, and some typical causes of uncertainty on actual measurement.
