ef_hdv_speed: Emissions factors for Heavy Duty Vehicles based on average...

Description Usage Arguments Value Examples

View source: R/ef_hdv_speed.R

Description

This function returns speed dependent emission factors. The emission factors comes from the guidelines EMEP/EEA air pollutant emission inventory guidebook http://www.eea.europa.eu/themes/air/emep-eea-air-pollutant-emission-inventory-guidebook
