Territorial impacts of innovative transport solutions

In recent years interest in urban mobility has grown considerably, not only due to the local increase in negative externalities generated by transport, but even because recent technological innovations are offering effective solutions especially in urban context. In particular, the introduction of Connected and Automated Vehicles (CAVs) could radically change the mobility scenario allowing, on the one hand, a widespread diffusion of vehicles in shared mode that feed the stations of the mass rapid transit, improving the attractiveness of Public Transport (PT), and on the other, the implementation of Travel Demand Management (TDM) measures on large areas of the most densely urbanized (and congested) territory of a city, without take the risk of reducing accessibility and creating social exclusion. The present study aims at evaluating, through a system of Land-Use Transport Interaction (LUTI) models, the impacts on transport demand and on population and activities location, deriving from the implementation of policies oriented to both enhancing PT and restricting the individual use of the car. The case study analyzed is represented by the urban area of Rome. Several scenarios have been simulated and compared by means of (economic, environmental and social) sustainability indicators. Preliminary results show that the improvement of PT services, combined with the introduction of restricted traffic areas and pedestrian zones, induce not only a significant modal shift towards more sustainable transport modes, but also a limitation of the urban sprawl.
