Nighttime road traffic noise exposure

The map shows the nighttime road traffic noise to which the population is exposed. The data is based on area-wide model calculations (sonBASE). Switzerland's entire road network, which was included in this calculation, covers approximately 68,000 km. Traffic data for road traffic was collected using a mobility model for 2015. The traffic data determined in this way was calibrated on the basis of approx. 1900 national and cantonal counting places with hourly fine counting values. The calculations are not legally binding. The only legally binding data relating to noise exposure and noise improvements are those issued by the responsible enforcement authorities, i.e. for motorways the Swiss Federal Roads Office (FEDRO), and for main and other roads the relevant cantonal authorities.
