Criteria Used in Determining Location, Nature and Length of MRT Noise Barriers
- Leon Perera asked the Ministry for Transport about the criteria for determining MRT noise barrier location, nature, and length, and whether barriers could be extended to fully cover residential areas near tracks.
- Khaw Boon Wan stated that the Land Transport Authority prioritizes installing noise barriers along elevated MRT tracks where noise levels in adjacent residential developments exceed the NEA's recommended threshold of 67 decibels averaged over an hour.
- The response did not directly address the second part of the question regarding extending barriers to fully cover residential areas, focusing instead on the existing noise threshold criterion.
