An Integrated Approach for Supporting the Evaluation of Transport Scenarios: The Area of Bellinzona (CH)

Multiple Criteria Decision Analysis (MCDA) is a widely-used tool to support decision processes when a choice between different options is needed. This approach is particularly useful in situation characterized by an inter-connected range of environmental, social and economic issues. Moreover the presence of many actors with different backgrounds and knowledge constitutes a further level of complexity due to the difficulty in interpreting and reading outputs. The present application is one response to tackle these difficulties.

The methodological framework is applied to a Swiss section of the transport corridor Genoa—Rotterdam, within the Interreg IVB NWE Project ‘‘Code24'' in order to demonstrate the potential of the 24 joint use of the two tools mentioned for the selection of a suitable strategy for transport improvement within territorial transformatio
