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 a measurement value, and noise exposed population was estimated according to noise map. The results show that four prediction values for traffic noise are a little different, because of various input factors according to the prediction methods. As a result of the exposed population, by using exposed population calculation method of Facade Noise Map through noise map, population in excess of 65dB(A) in the daytime and 55dB(A) in the nighttime, which are standards of the roadside, presented by Ministry of Environment, appeared as 2,353 in the day and night respectively. |
