Road traffic noise prediction model “ASJ RTN-Model 2003” proposed by the Acoustical Society of Japan - The framework and the accuracy of the prediction

摘要

Acoustical Society of Japan proposed “ASJ RTN-Model 2003” on April 1, 2004. It is an upgrade version of previous road traffic noise prediction method “ASJ Model 1998”. The new model is developed for its wide application to environmental impact assessment as well as monitoring of road traffic noise for checking the preservation of Environmental Quality Standard for Noise. In this paper the framework and the revised items of the model are described. Also, the accuracy of the prediction is presented by comparing the calculated and the measured values of noise around highways.
