Mobility and service networks and infrastructure

The transport of people, goods, materials, waste, energy and water is vital for the smooth operation of cities. Each type responds to very different criteria and needs and accordingly they must be considered as a whole, from planning through to their construction and subsequent management.

Mobility and service networks and infrastructure
High-capacity mobility infrastructure, which transports major flows of people and goods and is generally separated from urban fabrics, and the various service networks, which are related to the metropolitan water, energy, material and waste cycles, is necessary to guarantee the smooth operation of cities.

It is based on very different approaches and can therefore generate problems and dysfunctions when superimposed over other elements of the city. These networks must be integrated with minimal impact (such as that generated by railway lines crossing a neighbourhood, for example) and be open to the changes predicted to take place in the near future (energy model improvements, new means of transport, etc.).


Cities contain a series of networks that are linked to the metropolitan cycles and form part of the urban metabolism, such as those for water, energy, materials and waste. Their growth forecasts and the dimensions of their new infrastructure must be established in coordination with the competent bodies and institutions in accordance with the availability of land and the growth model. In this sense, special attention must be paid to their planning and current and future land needs with a view to correcting or rectifying the impacts they generate and, especially, the integration of those surrounded by new urban developments. Moreover, the PDU proposes a network model that will be able to address the processes of global change and energy transition, favouring decentralisation and closer links to the channels of the biophysical matrix and showing more resilience to the impacts of climate change.


In terms of planning, the road and rail network and the major intermodal nodes are key to the achievement of the future city model sought by the PDU. Fundamentally, their contribution is based on: strengthening the metropolitan area's ability to operate as a network; promoting a road system that connects the various parts of the metropolis; and maximising sustainable mobility in accordance with the existing space and resource constraints.
