In this paper same results of heavy vehicles traffic measurements were used to simulate the noise measurands by the CNOSSOS-EU methodfor this purpose. The heavy vehicles traffic volume and velocity were recorded by permanent automatic monitoring station. Thenoisewas calculatedin octave bands according to the CNOSSOS-EU method. The positionaland not positional measures of traffic noise were proposed for data scattering. The results was described using parameters such as the median, average peak noise, average maximum noise, average background level, first and third quartiles and relative measures of noise. Analyzes carried out for the tested section of the road showed that the traffic of heavy vehicles is notalways the main source of road noise. It has been shown that maximum values of the acoustic pressure occur for the frequency of f0=500Hz. The dispersion of noise and type A uncertainty of the results were evaluated.
