Abstract

Urban areas of Beirut suffer severe traffic congestion because of a deficient transportation system resulting in economic losses and adverse environmental impacts. Grade separations are proposed at several intersections to minimize this problem. Air quality, which highly depend on the geometric configuration of an intersection, is a major environmental concern. This paper presents an air quality impact assessment at a typical intersection where a grade separation is proposed. For this purpose, computer simulations
