Abstract
One of emission sources in the urban area have been identified as coming from the road traffic. Therefore, several simulation methods for traffic and pollution assessment are presented. There were analyzed the three main methods used for assessing the atmospheric air quality and the classification of air pollution models depending on multiple criteria. The mathematical models are used to describe the correlations between the meteorological conditions and the level of atmospheric concentrations of the pollutant emissions, analysis and interpretation of the experimental data. The primary objective of some specialised operational models is meant to supply a fast but still realistic assessment of the pollutant dispersion for the emissions due to the road traffic. The microscale numerical modelling offers the opportunity for a detailed simulation of the impact of various scenarios of urban planning, in order to establish and optimise the related strategic decisions.
