Debated in Parliament on 3 Feb 2026.
Mr Jackson Lam asked the Acting Minister for Transport (a) how the Ministry assesses noise generated by roads, MRT lines and airports as part of transport system design;(b) whether cumulative noise exposure on nearby residents is considered; and (c) how noise mitigation is prioritised alongside capacity and efficiency objectives in transport system design.
Noise impact assessments are conducted to determine the combined noise impact of all transport infrastructure as part of transport system design. Simulation models of projected noise levels help identify areas where cumulative noise may exceed the noise guidelines. Noise measurements are also taken on the ground. Noise mitigation measures are implemented where necessary. These measures include maintaining appropriate buffer distances from noise-sensitive developments, like residential areas, and implementing noise mitigation measures, such as noise barriers.
As for airports, aircraft is routed away from residential areas when wind conditions permit. Stringent aircraft noise requirements aligned with the International Civil Aviation Organization's requirements apply. A night curfew is also in place for Seletar Airport from 10.00 pm to 7.00 am every day, except for medical evacuation and emergency flights.
Overall, these approaches balance the aim of delivering efficient transport connectivity while maintaining liveable communities.
