COMPARATIVE STUDY OF THE CITY OF CACERES (SPAIN) IN NORMAL AND TRAFFIC REDUCTION CONDITIONS

Ciceres, a city in the middle west part of Spain (declared Patrimony of the Humanity by the UNESCO) has an irregular urbanistic distribution with a high proportion of narrow streets and avenues. This implies high levels of noise due to the traffic. By a categorisation procedure of the streets, noise levels (Leq, Lmax, Lmin, L10, L50 and L90) were measured in normal traffic conditions, at different hours in working days. With the celebration of the day without car, all the above mentioned levels were again measured in the coincidental points with the normal conditions. Frequency distributions for Leq, Lmax and Lmin in 1/3 octave bands were obtained in the day without car. In both situations traffic flows were counted. A decrease of about 50% of vehicles running in the day without car was detected, and as an average from the whole set of measurements, 3 dBA less for the energy-averaged sound level. Some comments are added relatives to the result of the day without car. (A) For the covering abstract see ITRD E113232.
