Noise contours night period for the base year 2021. Dataset was created within the framework of the EU Environmental Noise Directive. Dataset is made once every five years. This dataset is based on all provincial roads, calculated using calculation method CNOSSOS.However, at the request of Kenniscentrum Infomil, the traffic intensities of the year 2019 have been chosen to use the traffic intensities of the year 2019. Indeed, the intensities for the years 2020 and 2021 show a markedly lower volume of traffic due to the Corona measures.
