OVERVIEW

The teaching unit introduces students to the complex interactions that globally regulate the relationships between economic growth, mobility and sustainable development.

From a technological point of view, the problems related to the different uses of electrical systems in public and private mobility are summarized, highlighting in particular the aspects relating to performance, energy consumption, pollution.

Some peculiarities of the railway systems are treated and particular prominence is given to planning and economic problems in local public transport.
