Air quality - Immission traffic 2021 Nitrogen dioxide (NO2)

The file provides a picture of the air quality in terms of nitrogen dioxide around national, provincial and municipal roads in Gelderland for the year 2021. The data has been calculated nationally using the reporting tool. The concentration at 10 meters from the edge of the road is indicated for each road section. The air quality is shown in six concentration classes: exceedance of the limit value, an almost exceedance and the other values. The air quality is calculated, among other things, on the basis of traffic counts and calculation models. The sources, such as industry and agriculture, are included in the background concentration. The direct contribution from road traffic is also included in the total concentration. The values ​​calculated with the model have an inaccuracy of around 20-25 percent.
