Urban form and Sustainability: The Case Study of Rome

Abstract

This paper investigates the relation between sustainability and urban form. To this aim a system of Land-Use and Transport Interactions (LUTI) models has been designed and applied to the metropolitan area of Rome, to understand the interdependence of key variables such as travel behavior, transport supply, property values, jobs and residential location. The models represent the behavior of both dwellers and transport users and how they react to changing conditions. A system of assessment indicators has been defined to systematically test and compare alternative scenarios of urban form and to evaluate to what extent different locations and density distributions of activities achieve sustainability in terms of transport performances, social and environmental impacts.
