Selected vehicle emissivity assessment issues in passenger transport services

The paper presents an analytical method for determining the emissivity of transport modes, based on emissivity indicators for various vehicle types and statistical data. The method developed enables the determination of the emissivity of various vehicle types without the need to carry out tests on real vehicles. The purpose of this paper is to compare the vehicle emissivity results obtained using the developed analytical method with the real-world results obtained in RDE tests based on a case study, i.e. an analysis of the emissivity of passenger transport modes in Warsaw. The paper contains a summary of the results of measurements and calculations, as well as an analysis of potential areas of application for the developed analytical method.
