Modelling of internal combustion engines emission through the use of traffic flow mathematical models

Abstract

Road traffic flows on a straight road segment are modelled in this article. The mathematical model of traffic flows has been constructed by using the method of lumped parameters. CO2, CO, CH, NOx, PM regression equations of internal combustion engines (ICE) emission has been developed. The accuracy of regression equations is 0.98/0.99. The article presents assumptions for constructing the mathematical model, description of the mathematical model and gives simulation results. Traffic flow parameters, such as traffic flow concentration and traffic flow speed are presented as modelling results. ICE emission depending on the concentration and traffic flow speed are presented as well. © 2011 Copyright Vilnius Gediminas Technical University (VGTU) Press Technika.
