Noise Directive (DF4 and DF8): Strategic acoustic maps of major railways - LDWN index, 2017
Description
The collection contains acoustic maps for major railway lines, with traffic of more than 30 000 train journeys per year. The data shall include information on areas exposed to a specific noise level caused by rail traffic for the LDWN indicator (noise indicator for day, evening and night time). The data was compiled by railway managers. The data were subject to reporting to the European Commission in 2017, in accordance with the provisions of Directive 2002/49/EC (DF 4 and DF 8) - the Noise Directive. The data provided to the European Commission was updated in October 2018. The maps are updated every 5 years. LDWN is the long-term average sound level A in decibels (dB) determined in accordance with ISO 1996-2: 1987 for all days of the year (understood as a given calendar year in terms of sound emission and average year in terms of meteorological conditions), taking into account the time of day (understood as the time interval from 1hrs. 6 a.m. to 6 p.m. 6 p.m.), the time of the evening (understood as the time interval from 6 p.m. 6:00 p.m. to 6:00 p.m. 10 p.m.) and the time of night (understood as the time interval from 1 p.m. 10 p.m. to 10 p.m. 6 o'clock). It is used to determine the nuisance associated with noise exposure to LDWN. The data layer shall be representative of the regional annual situation.
