Noise pollution due
to road traffic is a major global concern because of its negative impact on the
quality of life in communities everywhere. In Republic of Serbia, traffic noise
has become an increasingly noticeable and serious problem in large cities like
Belgrade, Novi Sad, Nis, Kragujevacand Kraljevo.To resolving the current
situation, in cities where exists the intensive noise pollution from diesel
vehicles, as a special contribution to reducing noise in road traffic, we were
studied the replacement of the existing city busses with new propulsion system
on natural gas, resulting in less noise emission. The reduction of noise
emission was confirmed during parallel tests of the buses with drive on diesel
and natural gas. Intensive noise measurements were conducted according to the
Regulation UN ECE 51R.
