Abstract
Cities are as amazing places that let more than half of the world’s people -even three out of five by 2003- to live.
Moreover, green areas are highly valued to consider as crucial elements that meet the quality of life’s needs in
urban. Not only are green areas associated with social meanings and a context for social interaction; also serve a
tangible impact on controlling the air pollution and balancing the city dwellers’ needs such as clean high-quality
air and the optimum thermal features. The clarified correlation between air pollutant exposure and health effects
causes to lead the extensive studies to decrease the pollution and control temperature. This study focuses on
illustrating how the morphology of the green sidewalk could alter air pollution and thermal comfort. It is done by
categorizing slides of green sidewalks from Tehran, depend on their features, and analyzing by commercially
available software in order to clarify impacts of the morphology of green sidewalk on the level of pollution and
thermal comfort. The results offer a framework for selecting the optimum morphology, as a mathematical formula
in determining thermal comfort, by considering the height of plants as the pivotal feature in one hand, and the best
case to control pollution velocity.
