Abstract

Abstract: An average daily traffic (ADT)-based street classification method to assess urban noise has been experimentally analysed. Different statistical tests were applied to the noise levels and traffic flows measured in a medium-sized city (Mérida, Spain). The ADT-based classification method was compared to a previously proposed categorization method. The results obtained showed that not all of the statistical tests provided similar results, and that the ADT-based classification method provided good results with less overlapping categories/levels. It also showed a better classification of sampling points than the one obtained when applying the categorization method. Advantages and drawbacks of each classification procedure are discussed.
