Road traffic noise prediction model 'ASJ RTN-Model 2013' proposed by the Acoustical Society of Japan - Part 1: Outline of the calculation model

摘要

The Acoustical Society of Japan organizes the Research Committee on Road Traffic Noise to develop a prediction model of the road traffic noise. As results of the continuous research activities, the road traffic noise prediction model has been continuously published. Especially since 1993, the model has been released every five years. In this April, the latest version, "ASJ RTN-Model 2013", was published. It is an up-grade version of the previous model, ASJ RTN-Model 2008, and it was revised based on new knowledge and novel technology. In this paper, the calculation principle, the general procedure of the prediction calculation, the outlines of the revision of the ASJ RTN-Model 2013 are introduced.
