My research project starts with the concept that road intersections are no longer considered and evaluated as isolated means, but as part of a system. In the first phase i will implement the studies concerning roundabout corridors both as regards the phenomena related to equilibrium (in particular the braess paradox), and as regards the analysis of safety and efficiency, through dynamic simulations and geographical and safety investigations carried out with various software including: aimsun, ssam, gis, etc. In detail, the braess paradox is a problem that makes it difficult to estimate flows on evolving road corridors and it will be approached in a theoretical and practical way, using statistical methods and robust mathematics applied to the geography of transport. Instead, the second phase regards the study and application of new mobility and transport technologies, through modeling and subsequent experimentation, always to roundabout corridors, focusing on its and mobility with automated vehicles and on their interaction with the functionality and the geometry of the system of intersections in terms of emissions, efficiency and traffic safety. Of course, my research will be conducted through experimental applications in Pisa (Italy) and in Avignon (France).
