Abstract

It is known that cross roads are intensively polluting surface sources, first of all because of the high intensity of traffic, but also due to the very slow velocities of the motor driving cycles that occur, disadvantaged also by the old status of the fleet. As result, high momentum values of NOx and CO are recorded. The development of a modern city, the traffic refreshment and the limitation of heavy trucks in the central area of a city that is not benefiting of good advection, but of a bad infrastructure and ancient traffic fleet, are essential. Thus, after a long repeated series of on line measurements, the authors are recommending a statistical approach of determination of a specific emission factor, that might be used, in same or similar meteorological conditions and topography for limiting the traffic or characterising the by completing the emission inventory of a city also by superficial pollutant sources.
