| Abstract |
The various computer programs are used in computer simulation of the traffic noise prediction. But the difference or problem of calculation method used of road traffic noise prediction is not exactly investigated. In this paper, road traffic noise is predicted on the specific regions by using four prediction methods such as XPS31-133 model (France), RLS-90 model (Germany), ASJ model (Japen) and FHWA model (U.S.A), which are operated by a program named SoundPLAN, a program to predict road traffic noise. Those prediction values are compared with measured values. The results show that four prediction values of traffic noise are a little different from measured values, because of various input factors according to the prediction methods. |
