Theories of City Structure-The Multiple Nuclei Theory -         C.D. Harris & Ullman, 1945 Introduction: In, 1945 a less rigid model capable of application to a variety of urban patterns was proposed by C.D. Harris & E.L. Ullman. They suggested that landuse patterns of a city do not develop around a single centre. But on the contrary they develop around several discrete locations. This concentration of landuse patterns arouns various nuclei gives the city a cellular structure. This concept is particularly helpful in explaining the structure of Indian cities which are marked by definite periods of growth & often combine both new & old sections of the city for development. Main Goals:        i.           Move away from the concentric zone model.       ii.           To better reflect...

Theories of City Structure-Concentric Zone Theory Introduction: The Concentric or Zonal Theory of urban landuse was first proposed in 1923 by E.W. Burgess. He was a sociologist. The idea behind the concentric model is that the development of a city takes place outwards from its central area in a series of concentric circles to form zones.  Assumption:        i.           Cultural & social heterogeneity of the population.       ii.           Commercial-industrial base to the economy of the city.     iii.           Private ownership of property & economic competition for space.     iv.           Expanding area & population of the city.       v.    ...

Transport Problems in Urban areas The Linkage of urban centres is possible due to the development of road, rail, waterways & airways. Transportation lines act as the life for urban development without which the concentration of population & economic progress of the urban areas are not possible. Transport is necessary to satisfy the function & utility of a place. Now a days, the existence of cities depend on the costs of transport because we need the close link with transportation lines in terms of living space, location of shops, industries, educational institutions & accommodate large-scale activities of modern civilization.  The Function of Urban Transport:        i.           Transport is not only serving the city but it is part of the city. It occupies nearly 30 to 40 per cent land near the city centre & about 20 per cent land near the suburb. Cities are made up of buildin...
