Road traffic noise is one of the main environmental impacts of road infrastructures, so that efficient solutions are required for reducing noise exposure. Analyzing the noise action plans published in Spain it is observed a widespread lack of methodologies and criteria for the decision-making process on prioritizing road stretches in noise action plans. In this paper the main decision-making criteria are defined. Also, an objective and reasoned methodology, called PATRON, is developed, and these criteria are weighted for the construction of a normalized numerical index, the Road Stretch Priority Index. The weight of each decision-making criterion is determined by applying the Fuzzy Analytic Hierarchy Process to the results obtained from an expert panel. The developed methodology is implemented in a case study in order to test the validity of the weights assigned to the criteria in the decision-making problem under study. Priority Tranche Index. To do this, it is used successfully Fuzzy Analytic Hierarchy Process the results of an expert panel. The application of this methodology to a case study allowed the validation of assigning weights to these criteria studied the problem decision.
