The computation of noise levels is based on the German RLS 90 approach (Richtlinien fuer den Laermschutz and Strassen, Forschungsgesellschaft fuer Strassen- und Verkehrswesen), but applies some simplifications and minor modifications. Thus, noise levels should be considered as estimates rather than exact values. The conversion of noise exposures into monetary costs follows a slightly modified version of the German EWS approach (Empfehlungen fuer Wirtschaftlichkeitsuntersuchungen an Strassen, Forschungsgesellschaft fuer Strassen- und Verkehrswesen). A more detailed description of the computation methodology and the model limitations is provided in the related publications. See matsim.org/javadoc under "noise" for more information.
- noise (emission) levels on network links (based on traffic volume, share of heavy goods vehicles, speed level)
- noise (immission) levels at receiver points (based on the surrounding links' emissions and distances)
- population units (= population densities) at receiver points (mapping agents to the nearest receiver point)
- noise damages (= noise exposure costs) at receiver points (based on population units and noise levels)
