Noise on main roads — Level grid LDEN — mapping 2017
Description
The data include the calculation results of the 2017 environmental noise mapping on the main roads in Bavaria. Outside agglomerations, these are all motorways, federal and state roads, which, according to the 2015 traffic census, 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 cars per day. The noise indices LDEN and LNight in dB(A) are used as a measure of general nuisance or as a measure of sleep disturbances. The LDEN level is a 24-hour averaged immission level determined from the levels Lday, Levening and LNight for the assessment periods day (6:00-18:00), evening (18:00-22:00) and night (22:00-6:00). Weight factors of 5 dB(A) for the four-hour evening time and 10 dB(A) for the eight-hour night time take into account the increased noise sensitivity during these times. The layer represents noise pollution on major roads expressed by the noise index LDEN in accordance with the EC Environmental Noise Directive.
