Dataset description

The data includes the calculation results of the 2017 environmental noise mapping on the main roads in Bavaria. Outside of agglomerations, these are all motorways, federal and state roads that, according to traffic census in 2015, have a traffic load of more than 3 million vehicles per year. This corresponds to an average daily traffic strength (DTV) of more than 8,200 cars per day. Within agglomerations, these are all roads with a DTV of more than 8,200 vehicles per day. The noise indices LDEN and LNight in dB(A) are used as a measure of general harassment or as a measure of sleep disturbance. The LDEN level is an emission level averaged over 24 hours, calculated from the levels Lday, Levening and LNight for the assessment times day (6:00-18:00), evening (18:00-22:00) and night (22:00-6:00). Due to weight factors of 5 dB(A) for the four-hour evening time and 10 dB(A) for the eight-hour night time, the increased noise sensitivity during these times is taken into account. The layer represents the noise pollution on major roads expressed by the LNight noise index in accordance with the EC Environmental Noise Directive.
