The impact of infrastructural networks on nebula city (1965 – present), is a study of the changes in the character and shape of infrastructural networks. One of the motors of the metamorphosis of the compact city in an urban nebula is the growth of the infrastructure for transport and communication, in which the hubs of the network count. Studying these networks is essential for the understanding of the nebula city as a process of flows, an assembly of networks that extend over ever-larger distances.

The construction of infrastructural networks fits in a general, international pattern, which governs urban and later regional dynamics. The infrastructure of regions increasingly serves as a vehicle of a globalised flow of humans (in various capacities: workers, migrants, refugees, tourists), energy, communication messages etc. Multinationals choose their locations with an eye on the highway network, connections with worldwide telecommunication and superior systems energy provision, water supply or surveillance.

Infrastructural networks are crucial for the efficiency of collective arrangements of nebula city, because they facilitate various forms of economical, social, geographic and cultural exchange, articulate a link between production and consumption and constitute a substantial part of the physical and economical tissue of cities and city regions.
