It is well known that the European Noise Directive 2002/49/EC (END), proposes the incorpo-ration of quiet areas (QAs) as one of the objects of analysis. The data generated by this anal-ysis should define, among other things, if for the declaration of these QAs, the municipalities should take some measures, such as including noise mitigation measures in the action plans, or other urban planning measures to favor the use of them. However, the conditions neces-sary to carry out the best identification of QAs of the city are not specified nor harmonized, resulting in a collection of non-homogeneous data. In these circumstances, the EU Member States have the autonomy to establish their own criteria for the delimitation and planning of the QAs. The main objective of this study focuses on the possibility for developing a system of identification and ranking of QUA candidates inside agglomeration (or quiet urban areas) based on GIS. The criteria applied, seek a degree of flexibility that allows them to adapt to the specificities of medium-sized cities (between 50,000 and 250,000 inhabitants) located in Andalusia (a region situated in southern Spain). For this, three cities have been chosen as a case study, two of them have their strategic noise map. On-site surveys have been designed and carried out in a stratified way, describing the predilections of citizens for rest and leisure areas in the city. There have been more than 400 surveys per municipality from which a ranking of areas was drawn. To conclude, the results of the surveys are contrasted with the methods based on GIS applied in other European regions and extracted from the literature, with the idea of analyzing their suitability to be applied in Andalusia
