Air Pollution according to MLus-92
CadnaA enables to calculate the impact by air pollutants caused by road traffic according to a national German procedure, called MLuS-92, edition 1996 MLus92-96.
The calculation of air pollution according to MLuS-92 in CadnaA assesses - as with the simplified noise calculation in RLS-90 - a „Long Straight Road“ scenario. The calculation scheme opens by selecting the command Air Pollution from the road’s context menu. On the dialog, the relevant input parameters of this road are transferred from the Road dialog.
Alternatively, open the dialog from the Extras|Air Pollution menu. In this case, the corresponding parameters such as traffic counts, truck percentage etc. must be entered manually.
