By Michael Batty

In The New technological know-how of Cities, Michael Batty means that to appreciate towns we needs to view them no longer easily as locations in house yet as structures of networks and flows. to appreciate area, he argues, we needs to comprehend flows, and to appreciate flows, we needs to comprehend networks -- the family among items that contain the process of town. Drawing at the complexity sciences, social physics, city economics, transportation conception, neighborhood technological know-how, and concrete geography, and construction on his personal earlier paintings, Batty introduces theories and techniques that demonstrate the deep constitution of the way towns function.

Batty provides the rules of a brand new technology of towns, defining flows and their networks and introducing instruments that may be utilized to figuring out varied points of urban constitution. He examines the dimensions of towns, their inner order, the shipping routes that outline them, and the destinations that repair those networks. He introduces tools of simulation that variety from basic stochastic types to bottom-up evolutionary types to mixture land-use transportation types. Then, utilizing mostly an analogous instruments, he provides layout and decision-making versions that expect interactions and flows in destiny towns. those networks emphasize a idea with relevance for destiny learn and making plans: that layout of towns is collective motion.

Example text

We illustrate key notions in terms of road and rail networks, and we conclude by showing how scaling relates to these forms. These are foundations. The tools we introduce are supported by other theories and models of how cities organize themselves that we will take for granted in this book. We do not say much about dynamics here, even though the temporal dimension is crucial to complexity theory as it is applied to cities. We have explored dynamics elsewhere (Batty, 2005) and there are enough references to these ideas that the reader can explore these further.

In fact, this change is likely to be so great that we have no idea as to what the city of the medium-term future will look like, for we are only now acquiring the concepts and tools to think of the world in terms of interactions and networks rather than locations. Laying out these tools and demonstrating how we can use them effectively is one of the central missions of this book. In arguing for what is, in effect, a new paradigm—that we think of cities as sets of interactions rather than locations—we face the inevitable charge that we abandon the familiar in favor of the new.

But it is easy to see that the number of people T who can communicate face to face is much less than this; therefore T << P2, even if they are clustered together. Thus to achieve these economies of agglomeration, new forms of communication are required. In essence, the larger the city, the more likely it is for the city to have mechanisms in place that enable more and more people to communicate with one another efficiently. Moreover, these agglomeration economies that are achieved as cities grow bigger imply increasing returns to scale, which in turn imply falling transaction costs.
