The research aims at collecting information on the state of preservation of the cultural heritage in Palermo, and deals more precisely with Vittorio Emanuele avenue, itself bounded by two city gates called Porta Felice (northern gate facing the Mediterranean sea) and Porta Nuova (southern gate) that both give access to the historic centre of the city. Another important purpose is the assessment of livability level, be it for workers, residents, cultural operators, or else visitors, with a particular interest in traffic noise. The research has been conducted by means of miscellaneous scientific duties; however we shall only refer here to two types of practice : the monitoring of environmental noise and the monitoring of the level of air aggressiveness through the study of thermo-hygrometric and chemical aspects. Whereas the Corrosion Classification Coupon was useful for the measurement of corrosive agents in outdoor locations, outdoor HOBO Pro sensors were used to report temperature and relative humidity. Hence it was possible to define the acoustic climate on the avenue surveying both geometrical data as well as traffic flow and characteristics.
