The main topic of this work is the analysis of the integrated modelling of air pollutants emissions of light-duty vehicle in urban areas with dynamic traffic models. These models constitute fundamental components to support the development and assessment of traffic management policies, and the optimization of their parameters, to alleviate the negative impacts of road traffic. Furthermore, it is proposed and detailed a method for collecting real emission from light-duty vehicle in a dynamic traffic state. In this work, the details of the experiments for analysis of traffic simulators with integrated emission models are presented. Three traffic simulators have been used in the analysis: AIMSUN, INTEGRATION and VISSIM. The experiment showed that the emission limits established by law are not being observed/real for Particulate Materials (PM). The experiment showed that the estimative of PM from AIMSUN’s model is closest presented data real, since for Carbon Monoxide and Nitrogen Oxides the INTEGRATION’s model is better. In this work not employed calibration effort, showing the need for more accurate calibration for future researchs. For larger vehicles, lower emission rates were observed, depending on the modeling strongly consider the speed and acceleration to make the estimates. Finally, with the increase in traffic increased emissions of particulates were observed, but the oxides of carbon and nitrogen remained approximately constant with changes in the traffic.
