Efficiency analysis for sustainable mobility. The design of a mechanical vector in Amalfi Coast (Italy)

Efficient urban infrastructure interventions make it possible to pursue goals of sustainable mobility, that nowadays are extremely important in light of the need to reduce the negative impact produced by human activities on the environment. In addition and to a no lesser extent, the implementation of the investment requires the monetary resources to realise the works. In relation to this aspect, the scarcity of public funds in the current economic contingency makes the involvement of private capital and entrepreneurial skills indispensable in the execution and performance of these works. This work shows how the use of a suitable economic evaluation model is indispensable in order to encourage public-private partnerships aimed at the execution and correct management of an intervention in the field of sustainable mobility. The proposed evaluation model implements the instrument of inter-sectorial matrices, which allow to determine the impacts (output) generated by a change in aggregate demand (input, such as the investment costs in an industry) on the economy of the territory where the matrix is associated. The analysis and calculations are carried out in relation to the project for the construction of a mechanical vector in the town of Vietri sul Mare in the province of Salerno (Italy), which is useful in ensuring the decongestion of road traffic and the consequent reduction in travel times along the Amalfi Coast.
