Poliedra led the coordination of AIUTO project, funded by the European Commission within the Fourth Framework Program. The project developed a set of models simulating different transport demand management policies (road-pricing, park-and-ride) and flexible transport systems (dial-a-ride, car-pooling). The effects of each measure have been simulated by using real-data taken from six European cities (Como, Salerno, Randstad, York, Salonicco, Geneve) and assessed with multi-criteria analysis methods.
