Pollutant Distribution Modeling of Transportion Emission Sources Using IVE-ADMS Model for Roads and Terminals and ICAO-ADMS Model for Airports - Case Study: Tehran Metropolitant

As the share of transport in the production and emission of air pollutants is higher than other sources of emissions in cities, this makes it important for urban managers to identify these sources in detail. This paper deals with the combined effect of emission sources due to transport in the case study of part 9 and part 21 of Tehran metropolitan area. The Mehrabad Airport is considered as a volume source of emission, the passenger terminal as an area source of emission, and the roads in this region as a linear source of emission. For this study, the emission factors for Mehrabad Airport were first calculated using ICAO proposed approaches. To model the emission of pollutants in the streets and west terminals, the emission factors were first obtained using the IVE model, which was developed for Iran with the obtained driving cycle. In addition, with the emission factors obtained for the airport, terminals and routes concerned, the emission distribution model is obtained by combining the emission sources modeling system (ADMS). In total, this paper uses two combined methods of IVE-ADMS for routes and terminals, as well as the ICAO-ADMS model for airports. The results showed that SOX emissions were predominant at Mehrabad airport. Also, the emission of various pollutants in the study area and its 24-hour impact on the surrounding areas with its geographical coordinates are shown.
