ABSTRACT
Urban infrastructure networks-transportation, gas, electricity, water and telecommunications-provide the basic infrastructural foundations to the operation of modern economic and social systems. They provide access to energy, water and communications services through extensive physical networks of pipes, ducts, pylons, cables, radio, roads, rail and airline links. Such infrastructures are the conduits or ‘technological systems’ (Hughes, 1983; Preston, 1990) which link firms, organisations, and households into wider economic and social structures.
