Noise impact from all road traffic 4th tranche Lden (flat)

This file contains the Lden contours (55, 60, 65, 70 and 75 dB) of all provincial roads in 2021. This dataset shows the noise impact of provincial roads in the province of Groningen. The map is the result of legal obligations (from the Environmental Management Act). The dataset must be updated every 5 years. The data presents the contours at an observation height of 4 metres. The data relate to the annual average situation in 2021. Traffic intensities are not constant, and interventions can take place on and around the roads, causing noise levels to change. Small shifts in traffic intensities will have little effect on noise pollution.
