Environmental impact calculation and emissions calculation

The Visum add-on module PrT noise and pollutant emissions is used to calculate the noise emissions caused by motorized private transport. The Visum add-on module PrT noise and pollutant emissions is used to calculate the environmental impact (noise and pollutant emissions) caused by motorized private transport. The following procedure is available for calculating environmental pollution noise pollution:

• Noise calculation according to RLS-19 (Noise volume).

Calculation of the length-based acoustic power level according to RLS-19 (User Manual: Calculating noise volumes).

• Noise-Emis-Nordic (Noise volume)

Calculation of noise emission levels in accordance with Nordic Council of Ministers (1996) (User Manual: Calculating noise volumes).

• Pollution-Emis (Air pollution emissions)

Calculation of air pollution emissions in accordance with emission factors of the Swiss Federal Office for the Environment (BAFU) (User Manual: Calculating air pollution emissions).

The Visum add-on module HBEFA and COPERT allows you to calculate emission values in Visum by link, territory, or network-wide.
