A new way of looking at cities that has emerged during the last 20 years that could revolutionize planning and ultimately benefit city dwellers. ‘The Size, Scale and Shape of Cities’ advocates an integrated approach to the theory of how cities evolve by linking urban economics and transportation behavior with developments in network science, allometric growth and fractal geometry. Professor Batty argues that planning’s reliance on the imposition of idealized geometric plans upon cities is rooted in the nineteenth century attitude which viewed cities as chaotic, sprawling and dirty. Instead, he reports research that suggests beneath the apparent chaos, there is a strong order.
