چکیده مقاله
During the recent decades, rapid urbanization growth has led to even faster growth of motor vehicles especially in large cities Hence, evaluation of the actual level of traffic emissions has gained more interest This paper, for the first time, presents a bottom up approach for evaluation of vehicular emissions in Tehran the capital of Iran using the International Vehicle Emission IVE model The IVE model uses local vehicle technology levels and its distributions, power based driving factors, vehicle soak distributions and meteorological parameters to tailor the model for specific evaluation of emissions The results of this study demonstrate that carbon monoxide CO emission with 244 45 ton/hr during peak traffic hour is the most abundant criteria pollutant About 25% of this quantity is emitted during start up periods Other pollutants such as NOX, VOCs, PM, VOCevap and SOX are ranked after CO accordingly Also, carbon dioxide CO2 emissions of 1744 22 ton/hr during the study period indicate that light vehicles are responsible for more than 82% of this amount Based on IVE’s evaluation, about 25% of the total vehicle emissions in Tehran come from districts 2, 4 and 6 respectively It has further been inferred that the development of public transportation systems and proper land use and urban spatial planning for various centers in these districts are essential
