Boz 3&90, 7r62(f-Jor6fa^ ABSTRACT This paper presents an evaluation and modelling of air pollution in urban areas. To achieve the objective of this paper, eighteen major sites (eight signalized intersections and ten main rotaries) were selected in Irbid City-Jordan and taken as a case study. The traffic counts at these sites were performed during peak and off-peak hours taking into consideration the seasonal variations. Special technical equipment were used to measure the concentration of the following air pollutants : Carbon Monoxide (CO) , Sulfur Dioxide (SO.) , Nitrogen Oxides (NOx) , and particulate. The results showed that the effect of volume of Gasoline-Powered Vehicles on CO, NOx and particulate were statistically significant. While, the SO^ was found mor
