Dit bestand bevat de contouren Lden (55, 60, 65, 70 en 75 dB) van alle provinciale wegen in 20<\/SPAN>21<\/SPAN>.<\/SPAN> Deze dataset toont de geluidbelasting van provinciale wegen in de provincie Groningen. De kaart komt voort uit wettelijke verplichtingen (van de Wet milieubeheer). De dataset moet om de 5 jaar geactualiseerd worden<\/SPAN>. De data presenteren de contouren op een waarneemhoogte van 4 meter<\/SPAN>.<\/SPAN> <\/SPAN>De gegevens hebben betrekking op de jaargemiddelde situatie in 2021.<\/SPAN> <\/SPAN>Verkeersintensteiten zijn niet constant, en op en rond de wegen kunnen ingrepen plaatsvinden, waardoor de geluidsbelasting wijzigt. Als het gaat om kleine verschuivingen in de verkeersintensiteiten, zal dit weinig invloed hebben op de geluidsbelasting<\/SPAN>.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType":
