Noise from public transport: trams, metro and buses
Public transport is essential for sustainable cities, yet for residents living next to tram tracks or bus stops it can be a constant source of noise. Reports by the European Environment Agency and the World Health Organization list transport noise as one of the main environmental health risks in urban areas.
Where transport noise comes from
- Trams and metro — wheel‑rail interaction on curves, rail joints, braking at stops.
- Buses — acceleration, braking, idling diesel engines, roof‑mounted HVAC units.
- Infrastructure — switches, compressors, tunnel ventilation shafts.
Health impact
Large reviews in Lancet Public Health and WHO Europe documents link chronic transport noise to:
- increased risk of hypertension and heart disease;
- fragmented and poorer sleep quality even at seemingly “moderate” levels;
- higher stress and fatigue during the day.
What households can do
- upgrade to well‑sealed windows with suitable glazing and proper installation;
- place bedrooms on the quieter side of the building where possible;
- use wardrobes and bookcases along the noisy façade as extra sound screens;
- ventilate at night through the quieter side or via trickle vents instead of wide‑open windows to the tracks.
Using NoiseMap and formal complaints
When residents log complaints only in isolated letters, patterns are hard to see. Marking problematic stops and sections on NoiseMap and including these links in letters to transport authorities makes the issue visible and easier to prioritise.
What cities and operators can change
Transport experts and organisations such as UITP recommend a mix of measures:
- regular rail grinding and use of resilient fastenings;
- quieter rolling stock with modern bogies and brake systems;
- noise barriers at the most sensitive locations;
- speed reductions or limited night services near residential buildings.
Public transport will always create some noise, but with good data from residents and tools like NoiseMap, cities can balance mobility, climate goals and the right to sleep.
