A study was carried out in the behalf of a two-years research project, which had the following general objectives: formalization of an urban Land-Use Transport Interaction (LUTI) model and description of all components and connections; model specification and application in an urban area, definition of land use and transport policies; and simulation and assessment oftheir long-term effects. The paper presents the results of different urban policies simulation and assessment in the town of Reggio Calabria (Italy): land use, transport infrastructure and service, transport regulation and pricing policies. Long-term interactions between transport and activity systems simulation is performed through an urban LUTI model, while policy assessment is performed through a set of key indicators able to provide disaggregate measures related to the three dimensions of sustainability (environmental, social and economic). The study area includes the municipalityof Reggio Calabria, where the activity system is segmented in sectors to match available census residential and employment location data. Inter-dependencies between activity sectors are simulated through a Social Accounting Matrix (SAM), where some coefficients are fixed (e.g. those connected to employment of economic sectors) and others are price elastic (e.g. thoseconnected to available floorspace consumption). From inter-zones activityflows, transport demand is estimated through a three-step system of demand models that simulate emission, mode and path choices. Transport supply has two available transport modes: private and transit. The supply model for private modes is a congested network model, while transit services are represented through a line-based not-congested network model. Several land use and transport policies are simulated and compared with a reference scenario and their long-term effects are assessed through the estimation of aset of sustainability indicators.
