Abstract Background & objectives: The share of cars in large cities is obtained in the production and emission air pollution about 70%, and this is of fossil fuels mainly. Environment simulation in the form of environmental models to be many benefits, such as modeling accuracy and speed, particularly with the use of modern computers is very high. Using the model, scholars, researchers, administrators and policymakers can without time spending in the real world, to test the effects of new programs and ideas. Methods: Modeling based on Stella models software, was performed according to the data, and air quality changes model was designed in relation to the increase in vehicle. In fact, this model has predicted air pollution in the following years. Results: According to pollutants increasing trend in the following years, 4 ways in the software was applied that including, to reduce import vehicles, increase disposed cars, reducing distance and Euro 4 standard application, that results showed a decreasing trend for these pollutants. Conclusion: Its better that implementing policies to proceed for reduce pollutants with increase disposed cars method. Because, according to exit data of software most pollutants reduction has been achieved using this method. With the application all methods proposed in results, the amount of carbon monoxide and nitrogen oxides have decreased about 80% in 50 following years.
