Abstract: This paper presents a semi-empirical, analytical method for calculating emissions caused by heavy-duty vehicles. The method is based on raw data determined with the help of the German-Swiss |Heavy duty vehicle emission factors programme|, and is mainly founded on a systematized data structure. The systematization, which concerns the emission data and the driving behaviour data, gives access to a much broader database than the emission factors programme. The chosen method provides for an analytical assessment of emission- and traffic-relevant measures.

Keywords: driving cycles; dynamic emission behaviour; emissions calculation; emissions factor; fuel consumption; heavy-duty vehicles; heavy vehicles; vehicle emissions; exhaust emissions; air pollution.
