Abstract

A method of mixing polluted air with less polluted air to provide moderately polluted air. The method includes dividing air from a roadway region into a lower part and an upper part, and permitting at least a portion of the upper part to flow substantially in one or more flow directions toward a leeward region. The method also includes directing the lower part substantially upwardly in a direction substantially transverse to the flow direction to intersect with the upper part and to mix the polluted air with the less polluted air, to provide the moderately polluted air proximal to the leeward area.
