  7. Abstract:
  8. Tehran, with approximately 750 km2 of land area, a population of more than 8 million people with about 4 million active on-road vehicles, is dealing with serious air pollution problems. To model the environmental phenomenon precisely, this study aims to develop on-road air pollutant emission factor matrices based on existing traffic in Tehran routes and to run air quality modelling within Tehran geographic boundaries. We developed emission factor matrices using SMOKES-MOVES emission modeling system. To do so, we calculated on-road emission factors from actual traffic-related data and run MOVES emission model. And use use them for different pollutants considered in air quality models. Then, we used emission factors matrices in CAMx air quality assessment model in conjugation with WRF weather forecasting model. Results represent estimated primary and secondary pollutant concentrations at specific time and location. Through modeling emissions from all sources within study area in CAMx air quality model, results can be compared to actual concentrations measured at air quality monitoring stations
