Abstract. Urban transportation is one of the main sources of air pollution in mega cities, and urban job related trips can eectively in uence the state of air quality. Tehran, the capital of Iran, with a population of 7.3 million, was selected for this study. The present model is designed to investigate the eect on trac of the business working hours of dierent occupations and, as a result, on the status of air pollution. Daily job, non-job and recreational trips using the present vehicle eet is a major factor aecting air pollution in Tehran. In the context of the present study, the necessary information was utilized to dene some relations between job trips and pollutant emissions. The result showed that a proper adjustment of opening hours for dierent jobs can result in a reduction of pollutant emissions by as much as 20% during daily trac peak hours.
