Summary

Supplement 30 to the ITU-T Y-series Recommendations presents the overview of infrastructure in cities. Generally, the city infrastructure can be classified as digital/ICT infrastructure and physical infrastructure.

The intelligent improvement of physical infrastructure can be achieved through the widely adoption of information and communication technologies (ICTs). In this sense, ICT acts as an enabler to construct smart sustainable cities (SSC). Consequently using ICTs in SSC results in cost and energy saving, increased economic growth, improved quality of life (QoL), and reduced environmental footprint.
