Visum provides three models within the environmental impact model, to calculate the environmental impacts which are noise and pollution emissions, caused by motorized private transport (Environmental impact calculation and emissions calculation).
- Noise calculation RLS-19: Calculation of the emissions of the length-based acoustic power level of a source line per direction of travel according to the guidelines of the Forschungsgesellschaft für Straßen- und Verkehrswesen (FGSV).
- Noise-Emis-Nordic: Calculation of noise emission levels in accordance with Nordic Council of Ministers (1996).
- Pollution-Emis: Calculation of air pollution emissions in accordance with emission factors of the Swiss Federal Office for the Environment (BAFU).
