A proposal for a new way to understand cities and their design not as artifacts but as systems composed of flows and networks. In The New Science of Cities, Michael Batty suggests that to understand cities we must view them not simply as places in space but as systems of networks and flows. To understand space, he argues, we must understand flows, and to understand flows, we must understand networks—the relations between objects that compose the system of the city. Drawing on the complexity sciences, social physics, urban economics, transportation theory, regional science, and urban geography, and building on his own previous work, Batty introduces theories and methods that reveal the deep structure of how cities function. Batty presents the foundations of a new science of cities, defining flows and their networks and introducing tools that can be applied to understanding different aspects of city structure. He examines the size of cities, their internal order, the transport routes that define them, and the locations that fix these networks. He introduces methods of simulation that range from simple stochastic models to bottom-up evolutionary models to aggregate land-use transportation models. Then, using largely the same tools, he presents design and decision-making models that predict interactions and flows in future cities. These networks emphasize a notion with relevance for future research and planning: that design of cities is collective action.

A novel, integrative approach to cities as complex adaptive systems, applicable to issues ranging from innovation to economic prosperity to settlement patterns. Human beings around the world increasingly live in urban environments. In Introduction to Urban Science, Luis Bettencourt takes a novel, integrative approach to understanding cities as complex adaptive systems, claiming that they require us to frame the field of urban science in a way that goes beyond existing theory in such traditional disciplines as sociology, geography, and economics. He explores the processes facilitated by and, in many cases, unleashed for the first time by urban life through the lenses of social heterogeneity, complex networks, scaling, circular causality, and information. Though the idea that cities are complex adaptive systems has become mainstream, until now those who study cities have lacked a comprehensive theoretical framework for understanding cities and urbanization, for generating useful and falsifiable predictions, and for constructing a solid body of empirical evidence so that the discipline of urban science can continue to develop. Bettencourt applies his framework to such issues as innovation and development across scales, human reasoning and strategic decision-making, patterns of settlement and mobility and their influence on socioeconomic life and resource use, inequality and inequity, biodiversity, and the challenges of sustainable development in both high- and low-income nations. It is crucial, says Bettencourt, to realize that cities are not "zero-sum games" and that knowledge, human cooperation, and collective action can build a better future.

Cities are a big deal. More people now live in them than don't, and with a growing world population, the urban jungle is only going to get busier in the coming decades. But how often do we stop to think about what makes our cities work? Cities are built using some of the most creative and revolutionary science and engineering ideas – from steel structures that scrape the sky to glass cables that help us communicate at the speed of light – but most of us are too busy to notice. Science and the City is your guidebook to that hidden world, helping you to uncover some of the remarkable technologies that keep the world's great metropolises moving. Laurie Winkless takes us around cities in six continents to find out how they're dealing with the challenges of feeding, housing, powering and connecting more people than ever before. In this book, you'll meet urban pioneers from history, along with today's experts in everything from roads to time, and you will uncover the vital role science has played in shaping the city around you. But more than that, by exploring cutting-edge research from labs across the world, you'll build your own vision of the megacity of tomorrow, based on science fact rather than science fiction. Science and the City is the perfect read for anyone curious about the world they live in.

How we can invent—but not predict—the future of cities. We cannot predict future cities, but we can invent them. Cities are largely unpredictable because they are complex systems that are more like organisms than machines. Neither the laws of economics nor the laws of mechanics apply; cities are the product of countless individual and collective decisions that do not conform to any grand plan. They are the product of our inventions; they evolve. In Inventing Future Cities, Michael Batty explores what we need to understand about cities in order to invent their future. Batty outlines certain themes—principles—that apply to all cities. He investigates not the invention of artifacts but inventive processes. Today form is becoming ever more divorced from function; information networks now shape the traditional functions of cities as places of exchange and innovation. By the end of this century, most of the world's population will live in cities, large or small, sometimes contiguous, and always connected; in an urbanized world, it will be increasingly difficult to define a city by its physical boundaries. Batty discusses the coming great transition from a world with few cities to a world of all cities; argues that future cities will be defined as clusters in a hierarchy; describes the future “high-frequency,” real-time streaming city; considers urban sprawl and urban renewal; and maps the waves of technological change, which grow ever more intense and lead to continuous innovation—an unending process of creative destruction out of which future cities will emerge.

Nearly 4,000 cities on our planet today have populations of 100,000 people or more. We know their names, locations, and approximate populations from maps and other data sources, but there is little comparable knowledge about all these cities, and none that can be described as rigorously scientific. The Planet of Cities together with its companion volume, the Atlas of Urban Expansion, contributes to developing a science of cities based on studying all these cities together—not in the abstract, but with a view to preparing them for their coming expansion. The book puts into question the main tenets of the familiar Containment Paradigm, also known as smart growth, urban growth management, or compact city, that is designed to contain boundless urban expansion, typically decried as sprawl. It examines this paradigm in a broader global perspective and shows it to be deficient and practically useless in addressing the central questions now facing expanding cities outside the United States and Europe. In its place Shlomo Angel proposes to revive an alternative Making Room Paradigm that seeks to come to terms with the expected expansion of cities, particularly in the rapidly urbanizing countries in Asia and Africa, and to make the minimally necessary preparations for such expansion instead of seeking to contain it. This paradigm is predicated on four propositions:1. The expansion of cities that urban population growth entails cannot be contained. Instead we must make adequate room to accommodate it.2. City densities must remain within a sustainable range. If density is too low, it must be allowed to increase, and if it is too high, it must be allowed to decline.3. Strict containment of urban expansion destroys the homes of the poor and puts new housing out of reach for most people. Decent housing for all can be ensured only if urban land is in ample supply.4. As cities expand, the necessary land for public streets, public infrastructure networks, and public open spaces must be secured in advance of development.The first part of the book explores planetary urbanization in a historical and geographical perspective, to establish a global perspective for the study of cities. It confirms that we are in the midst of an urbanization project that started in earnest at the beginning of the nineteenth century, has now reached its peak with half the world population residing in urban areas, and will come to a close, possibly by the end of this century, when most people who want to live in cities will have moved there. This realization lends urgency to the call for preparing for urban expansion now, when the urbanization project is still in full swing, rather than later, when it would be too late to make a difference.The second part of the book seeks to deepen our understanding and thus lessen our fear of urban expansion by providing detailed quantitative answers to seven sets of questions regarding the dimensions and attributes of urban expansion:1. What are the extents of urban areas everywhere and how fast are they expanding over time?2. How dense are these urban areas and how are urban densities changing over time?3. How centralized are the residences and workplaces in cities and do they tend to disperse to the periphery over time? 4. How fragmented are the built-up areas of cities and how are levels of fragmentation changing over time?5. How compact are the shapes of urban footprints and how are their levels of compactness changing over time?6. How much land would urban areas require in future decades?7. How much cultivated land will be consumed by expanding urban areas?By answering these questions and exploring their implications for action, this book provides the conceptual framework, basic empirical data, and practical agenda necessary for the minimal yet meaningful management of the urban expansion process.The companion volume, Atlas of Urban Expansion, was also authored by Lincoln Institute visiting fellow Shlomo “
