Computation of road traffic noise levels and noise damages
Availability Contrib
Status Unknown
Maintainer Ihab Kaddoura
API Documentation See Javadoc overview page
User Documentation This package provides some tools to compute...
  • 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)
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.
