An applied test to evaluate the use of fluid dynamic code as a predictive key of air pollution from urban road traffic

Urban air pollution is certainly a direct function of the consistency of flows of motor vehicles travelling through each zone of a city, of the geometry of buildings at the boundary of streets where conditions effect the dispersive fluid dynamics of exhaust gases and, of course, of meteoclimatic features of various zones that form the whole urban area.The planners of the “Plan of Urban Traffic” (PUT) actually take into account the sole possibility of increasing the average speed of the run of traffic flow but they do not consider the health hazard for city dwellers that may be caused by PUT as regards air pollution coming from exhaust pipes, especially in a supersaturated urban area.
