Primary Institution: Macau University of Science and Technology
Hypothesis
How does urban form influence pedestrian exposure to traffic noise in the Macao Peninsula?
Conclusion
The study found that about 60% of traffic noise levels along major pedestrian sidewalks in the Macao Peninsula exceed the National Standard of 70 dB(A).
Supporting Evidence
- 60% of traffic noise levels along major pedestrian sidewalks exceed the National Standard of 70 dB(A).
- 21% of traffic noise levels are above the National Standard by 5 dB(A).
- The weighted average traffic noise levels in Urban Areas 1, 2, and 3 are 69.76 dB(A), 69.84 dB(A), and 72.76 dB(A) respectively.
Takeaway
In Macao, many sidewalks are too noisy because of traffic, making it uncomfortable for people walking there.
Methodology
A GIS-based traffic noise model system was used to assess pedestrian exposure to traffic noise along sidewalks.
Limitations
The distribution of receptor points was not uniform, which could lead to overestimation or underestimation of average traffic noise levels.
