چکیده مقاله:

The purpose of the paper is modeling and determining motor vehicle participation in NOX emission in Arak. Arak that faces traffic congestion due to old urban structure as well as too many cars, is one of extremely industrialized and densely populated cities in Iran.In this research, busy streets have been modeled at the most congested hours. Additionally, the amount of NOX emission released by cars are investigated according to various weather conditions within one year to cure air pollution crisis by providing solutions such as traffic flow plan, change in urban structure, and the prevention of passing polluting fossil fuel vehicles.In the paper, synoptic meteorological data, the data of over the atmosphere(upper data), topographic maps and information about vehicles have been employed simultaneously in Aermod software.IVE model has been applied to investigate the volume of vehicles emissions that the type and number of vehicles and the quality of traffic in corresponding street have been considered.The results revealed that the annual average of NOX is about 1690 μg/m3 in downtown and some congested points such as Piroozi Street, by contrast, It is more than 8 times of the global standard of 200 μg/m3. In consequence, endeavor to surmount the crisis is vital.
