The problem of accessibility in sustainable mobility: a conceptual framework and its applications

This paper will focus on accessibility and its relationship with sustainability, with particular attention to peri-urban and rural areas. The paper will be divided into four main sections. In the first part, we will give a basic knowledge on the accessibility concept throughout an accurate review of the literature available, studying the continuous evolution of the concept during the past decades with a particular focus on its heterogeneity. Second, using statistical data available on Internet, we will run a meta-analysis, studying the sensitivity of each measure in relation to the problems deriving from a lack of accessibility. In the third part we will present an application of the results obtained in a GIS environment, using graphical representations to better explain the concept. Finally, we will present the results of our study and the conclusions following to the paper, with suggestions for further researches.
