A paper originating from our EU FP7 Insight project on extending land use transportation models to embrace better sub models of the retailing sector. Our paper entitled “Quantifying Retail Agglomeration using Diverse Spatial Data” by Duccio Piovani, Vassilis Zachariadis and myself has just been published in Scientific Reports – you can download it here. The model partitions the agglomerating effects of retailing into two scales: the typical zonal scale where consumers travel to shopping centres of different sizes and at different distances/travel times from the places where they generate their demand for such goods, and shopping centres themselves where shops of different and like sorts agglomerate, thus affecting the demand for particular retails goods within each shopping centre. The model is quite straightforward in that it has the structure of a nested logit model of discrete choice where the nests are the shopping centres within which the individual retailing facilities are located. We fit the model to data for the inner area of the Greater London region, and you can get the results from the paper.
Questioning what bigness means in terms of Big Data and the City is a key quest in understanding what the massive increase in data volumes means to understanding the urban challenges that lie ahead and our future planning of the city to alleviate the many problems that currently beset them. Kitchin, Lauriault, and McArdle’s book Data and the City is “…the first edited collection to provide an interdisciplinary analysis of how this new era of urban big data is reshaping how we come to know and govern cities, and the implications of such a transformation. This book looks at the creation of real-time cities and data-driven urbanism and considers the relationships at play. By taking a philosophical, political, practical and technical approach to urban data, the authors analyse the ways in which data is produced and framed within socio-technical systems. They then examine the constellation of existing and emerging urban data technologies. The volume concludes by considering the social and political ramifications of data-driven urbanism, questioning whom it serves and for what ends” (from the Routledge web site).
I have a paper in the book about big data: Batty, M. (2017) Data About Cities: Redefining Big, Recasting Small, in Kitchin, R., Lauriault, T. P., and MaArdle, G. (Editors) Data and the City, Routledge, London, 31-43, that you can download here in its original form.
In this paper (downloadable here), I argue that the smart cities movement is simply the latest stage in the massive dissemination of digital computation that began with its invention some 70 or more years ago. In fact, the key thesis in the paper is that digital automation is simply the outcome of dramatic transition from a world without machines to one with, that digital technologies are the natural end-state of a process of automation that marks the ascent of man in general. This became evident with the rapid super-exponential change in technologies marked by the first industrial revolution which lead to the invention of the steam engine, then proceeding at pace through electrical and then into the digital revolution. In this context, I argue that the smart cities movement is the essence of the sixth Kondratieff wave. In developing this, I relate these waves of technological innovation to the prospect of all waves speeding up and collapsing into a singularity while in parallel, continuing into a regime of permanent creativity at the individual level
This paper also reflects on how the smart city can be defined and the difficulties in providing a coherent framework for its understanding and analysis. To an extent, smart cities are simply one feature of the city and to generate any collective and comprehensive understanding, ideas and technologies defining it must be related to every other perspective on the city. In this paper, I allude to the notion that the world population will stabilise during this century – that the demographic transition will work itself out and when we look back from the distant future, we will see this period as one in which the world moved rapidly from a non-urban regime to an urban one. In an earlier paper, I elaborated this argument in a commentary entitled “When all the world’s a city” which you can download here and can be read alongside the new article (also accessible on Research Gate).
