Abstract

Vehicular traffic represents one of the most important sources of noise and environmental pollution in urban centres. The concentration values of main atmospheric pollutants (COx, NOx, SOx, O3, HC, PM) strongly depend on atmospheric conditions and traffic flow features (composition, mean speed, utilized fuels, driving conduct, etc). This information about traffic, except engine data, can be obtained from acoustical data, by considering the time behaviour of Leq and a suitable set of statistical noise levels Ln, (as defined in ISO 1996). In this paper we analyse the results of a noise and atmospheric pollutants concentrations levels measurement campaign carried out in a typical urban centre. The pollutants concentration and climatological data have been compared to the acoustics indicator values measured in the same overall environmental and traffic conditions, in order to put in evidence the influence of the above traffic features on pollutants concentration levels. For a better phenomenological understanding, an innovative "noise-like" statistical approach has been developed, by introducing opportunely modified statistical levels of concentration.
