Propuesta de una nueva metodología para la ubicación de infraestructuras viarias ambientalmente sostenibles. Aplicación en el tramo viario de la pedemontana Fabriano- Muccia

Abstract

This study deals with the creation of a model to define the best allocation within the area of new projects for road infrastructures, and to evaluate the effectiveness of a road which is part of a wide-ranging project currently under construction, known as the Marches-Umbria Quadrilateral Project. The aim of the work is to develop a speedy, versatile instrument which will be able not only to calculate but also to interpret and correlate the various environmental, social, economic, technical and operational aspects of the construction of road works. Special attention is paid to the dynamics of the use and consumption of the natural habitats and the problems linked to the phenomena of ecological fragmentation caused by the road network and by settlements. The methodology which has been developed includes the collection and implementation within a dedicated territorial informative system of a wide range of information capable of defining the special characteristics of the area under study, which will then be interpreted and summarised by means of the application of a series of specific indicators. The defined indicators are subsequently integrated by applying techniques of multi-criterial analysis to define an index of concise evaluation capable of assessing and supporting the sensitivity of the territory to the integration of new road infrastructures. In order to validate the methodology, the proposed indices were applied to a study area in which a road infrastructure of considerable importance is currently being built to link central Italy from one side of the country to the other.
