Sydney

Question 1

Ullman and Harris city model (1945)

Answer 1

• Modern cities are more structured than Burgess and Hoyt.
• Cities do not grow from a single CBD center, but from many smaller centers (nucleus)
• Each of the smaller centers has the function of a growth point, but has a specific function - a financial centre, an administrative centre, a retail centre, an industrial centre)
• Over time, growth will be generated by each of the smaller centers, until each of the centers (nucleus) merges into one large urban center.
• When the city becomes too big and crowded parts of the functions are moved to smaller
  centers (nuclei)
• The model of Ullman and Harris assumes maximum communication accessibility to the city center, separation of various functions of the urban tissue from each other, diversification in land prices.
