The choice is almost unavoidable: either you use the underground or you have to fly! The surface, especially in big cities, doesn’t allow for much manoeuvring anymore. The major factors driving change in large towns and their hinterlands – also in view of reducing the environmental impact of traffic on the surface – are: the great number of travellers moving to and fro every day, the poor growth of services and facilities – also due to the policies linked to expenditure reduction -, the rapid expansion of metropolitan areas and the boost of private transport.

That is why the issues concerning locai transportation, commuting and sustainable mobility are increasingly turning into the top items in the agenda of the new Administrations of large and medium cities. For all these reasons, metro authorities have no option but to exploit underground spaces, building metro line after metro line and excavating deeper and deeper.
