Sustainable urban land use and transportation planning: a decision support system for the Naples metropolitan area

Increasing needs for higher mobility are often met by design and implementation of new infrastructure provisions. The challenging question is whether this choice increases the general political objective of sustainable development. In this context, also the land-use and transportation interfaces have to be envisaged. The paper aims to offer a methodological/operational contribution to sustainable mobility policy in the Naples metropolitan area (in the Campania Region , Italy). Scenario analysis is used to design combined land-use/transportation plans to be assessed from a sustainability perspective. Long-range choice options are evaluated using inter alia a sophisticated multicriteria analysis (i.e., hierarchical Regime method). Sensitivity analyses will test the robustness of policy rank order solutions found by the above multicriteria analysis.
