Urban planning and development in Tehran

With a population of around 7 million in a metropolitan region of 12 million inhabitants, Tehran is one of the larger cities of the world. This paper charts its planning and development through the ages, particularly since the mid-20th century, a period in which the city has gained most of its phenomenal growth. Three phases are identified in this historical process, with different types of urban planning exercised through infrastructure design and development, land use regulation, and policy development.
