The noise that comes from the road traffic, along with other emitters of environmental noise has a largely negative impact on quality of life. In the Republic of Serbia as in communities everywhere in the world, the noise that comes from the road traffic has become an increasingly noticeable and serious problem which is especially pronounced in large industrialized cities. In the paper are presented the results of intensive noise level measurements in the city of Kragujevac obtained during the 24-h measurements at specific critical locations. The results of measurement are linked to the frequency of the city traffic, which indicates on the presence of certain categories of vehicles during the measurements. Regarding to the current situation, as a special contribution to reducing noise in road traffic, it is proposed solution in terms of replacement of the existing city buses with diesel engines, with original engines or vehicles on Compressed Natural Gas CNG, that produce less noise emission, are more economical and they have no emission of smoke and particles in the exhaust gases. This was confirmed with parallel tests of the buses with drive on diesel and CNG. The results obtained by measuring the noise of the vehicles according to the Regulation UN ECE 51R, are shown a significant noise reduction compared to the situation when used diesel buses.
