Round 4 Noise Maps and Noise Mapping Technical Reports
Date published:
In compliance with the Environmental Noise Regulations (ENR), round 4 noise maps have been produced based on 2021 data for the following sources:
- Major roads - roads with more than 3 million vehicle passages annually.
- Major railways - railways with more than 30,000 train passages annually.
- Major airports - airports with more than 50,000 movements annually.
- Agglomerations - urban areas with more than 100,000 inhabitants, taking into account the above sources other roads, railways, aircraft movements and industrial premises.
Round 4 maps and associated Technical reports are available below.
