| Summary: | Transverse roadway strips (TRS) are a common approach used by the local authorities in Malaysia
for the purpose of road safety on rural roadway. However, there were complaints made by residents about the
excessive noise pollution produced by TRS. The objective of this study was to evaluate the external noise
produced by the application of TRS, to evaluate and to anticipate the annoyance response due to installation of
TRS. The investigations were carried out through the changes of noise level indices, estimation of the
annoyance response using the traffic noise index (TNI) and anticipation of resisident response anoyance.
Measurements of the external noise level produced by the TRS were taken for two hours at two location with
and without TRS. Results showed that TRS increased the equivalent noise level, LAeq1hour, L101hour and L901hour by
as much as 14 dB(A), 16 dB(A) and 9 dB(A) respectively. TNI values also increased as much by as 42% and
exceeded the suggested value for planning purposes of 74 dB (A) for 3% annoyance from the social surveys.
This investigation shows that TRS noise has a very strong impact on the community and this was the reason
behind the complaints made by people living in study area. |
