New Measures to Reduce Impact of Loud Traffic Noises on Residential Housing Situated Near Expressways

Mr Liang Eng Hwa asked the Minister for Transport (a) whether the agencies are looking at new measures to reduce the impact of loud traffic noises on residential housing situated very near the expressways; and (b) whether Ministry is looking at new technologies to reduce such traffic noises and improve the quality of living in such areas.

The Land Transport Authority (LTA) has completed trials on the effectiveness of noise barriers and low noise pavement mix. The trials showed that these measures could potentially reduce noise for residents living near expressways. LTA intends to roll out some of these measures progressively.

When rolling out these measures, LTA has to consider multiple factors such as site-specific conditions and overall cost effectiveness. For example, noise barriers would not be suitable in locations where they may obstruct motorists' view.

In addition, LTA will continue to explore with other agencies new measures which can effectively mitigate the impact of traffic noise and improve the quality of living of our residents living near expressways.
