Abstract

The paper addresses the optimization of an idealized urban geometry, as defined by building height and street width, to minimize the effect of automotive pollution as evidenced by CO concentration levels. There is an increasing interest in the contribution of automotive pollution to urban air pollution. The formulation of building regulations, as well as the optimization of proposed street-use patterns, require modeling studies of the pollutant dispersion due to automotive emissions. The dispersion is closely linked to the geometrical features and meteorology of the urban environment. This paper uses the techniques of Computational Fluid Dynamics (CFD) to calculate the dispersion of CO emitted by traffic in a section of an urba
