Statistical analysis on ante-operam data collected in the Quiet Urban Areas selected by the LIFE+2010 QUADMAP project

QUADMAP (QUiet Areas Definition and Management in Action Plans) is a LIFE+2010 Pro-ject on Quiet Urban Areas which aims to deliver a method regarding identification, delinea-tion, characterization, improvement and managing of Quiet Urban Areas (QUAs) as meant in the Environmental Noise Directive 2002/49/EC. The project will also help to understand the definition of a QUA, the meaning and the added value for the city and their citizens in terms of health, social safety and lowering stress levels. At the beginning of 2013 the first version of a methodology to select, analyze and manage QUAs has been produced and subsequently applied in ten pilot areas chosen in Firenze, Bilbao and Rotterdam. During the analysis phase, quantitative (noise maps and acoustic measurements) and qualitative (end-users question-naires, general and non-acoustic information) data have been collected and examined. Once the ante-operam phase of analysis has been completed, the interventions’ realization in the pilot areas started and was followed by post-operam surveys. In this paper, results of the carried out statistical analysis based both on quantitative and qual-itative data acquired in the city of Florence during the ante-operam phase are presented. In particular, the use of logistic regression and ordinal logistic models is investigated. The use of multidimensional techniques aims to evaluate the net effect of single variables.
