Underground superimposed railways and motorways optimize energetic and technical supply while reducing soil consumption, noise and air pollution, in a relation of symbiosis and mutual valorisation with the natural and artificial landscape. Land art expressions or creative solution for environmental compensations and green energy production are foreseen along the network.
The HUB is planned to host different services: from parking to multi-modal transport interchange areas, from train station to warehouses, logistic services and offices. Travelling from a city to another, people and goods reach the corresponding HUB and commute to a more effective and suitable means of transport towards another HUB or city. Scale economy and a planned distribution chain save resources and benefit the environment. Moreover, the HUB constitutes a site specific centre valorising local specificities and products. Node on the national infrastructure, it offers a direct contact with the surrounding area.
