Night Noise Exceedance Areas for Roads and Railways in Haute-Garonne, 2017-2022

Haute-Garonne department areas where night noise from roads and railways exceeds legal limits. The dataset identifies residential, educational, and health buildings exposed to noise levels above 62 dB(A) for roads and 65 dB(A) for railways between 22:00 and 06:00. It was produced by the Bureau de Recherches Géologiques et Minières for strategic noise mapping under the Environmental Code.

Use Cases

• Identify residential buildings exposed to excessive night-time road noise for regulatory compliance checks.
• Map areas around educational facilities where railway noise exceeds the 65 dB(A) limit for health impact studies.
• Support strategic noise mapping for the Haute-Garonne department as required by Article R.572-5 of the Environmental Code.
• Analyze spatial correlation between transportation infrastructure and noise exceedance zones affecting health buildings.

Strengths

• Specific noise thresholds defined: 62 dB(A) for roads and 65 dB(A) for railways.
• Clear temporal scope for night hours (22:00-06:00) and date range (2017-2022).
• Focus on three sensitive building types: residential, educational, and health facilities.
