The Computable City: Histories, Technologies, Stories, Predictions

Curated on March 5, 2024March 7, 2024 by Stefaan Verhulst

Book by Michael Batty: “At every stage in the history of computers and communications, it is safe to say we have been unable to predict what happens next. When computers first appeared nearly seventy-five years ago, primitive computer models were used to help understand and plan cities, but as computers became faster, smaller, more powerful, and ever more ubiquitous, cities themselves began to embrace them. As a result, the smart city emerged. In The Computable City, Michael Batty investigates the circularity of this peculiar evolution: how computers and communications changed the very nature of our city models, which, in turn, are used to simulate systems composed of those same computers.

Batty first charts the origins of computers and examines how our computational urban models have developed and how they have been enriched by computer graphics. He then explores the sequence of digital revolutions and how they are converging, focusing on continual changes in new technologies, as well as the twenty-first-century surge in social media, platform economies, and the planning of the smart city. He concludes by revisiting the digital transformation as it continues to confound us, with the understanding that the city, now a high-frequency twenty-four-hour version of itself, changes our understanding of what is possible…(More)”.

How will AI shape our future cities?

Article by Ying Zhang: “For city planners, a bird’s-eye view of a map showing buildings and streets is no longer enough. They need to simulate changes to bus routes or traffic light timings before implementation to know how they might affect the population. Now, they can do so with digital twins – often referred to as a “mirror world” – which allows them to simulate scenarios more safely and cost-effectively through a three-dimensional virtual replica.

Cities such as New York, Shanghai and Helsinki are already using digital twins. In 2022, the city of Zurich launched its own version. Anyone can use it to measure the height of buildings, determine the shadows they cast and take a look into the future to see how Switzerland’s largest city might develop. Traffic congestion, a housing shortage and higher energy demands are becoming pressing issues in Switzerland, where 74% of the population already lives in urban areas.

But updating and managing digital twins will become more complex as population densities and the levels of detail increase, according to architect and urban designer Aurel von Richthofen of the consultancy Arup.

The world’s current urban planning models are like “individual silos” where “data cannot be shared, which makes urban planning not as efficient as we expect it to be”, said von Richthofen at a recent event hosted by the Swiss innovation network Swissnex. …

The underlying data is key to whether a digital twin city is effective. But getting access to quality data from different organisations is extremely difficult. Sensors, drones and mobile devices may collect data in real-time. But they tend to be organised around different knowledge domains – such as land use, building control, transport or ecology – each with its own data collection culture and physical models…(More)”

To Design Cities Right, We Need to Focus on People

Curated on February 19, 2024February 21, 2024 by Stefaan Verhulst

Article by Tim Keane: “Our work in the U.S. to make better neighborhoods, towns and cities is a hapless and obdurate mess. If you’ve attended a planning meeting anywhere, you have probably witnessed the miserable process in action—unrestrainedly selfish fighting about false choices and seemingly inane procedures. Rather than designing places for people, we see cities as a collection of mechanical problems with technical and legal solutions. We distract ourselves with the latest rebranded ideas about places—smart growth, resilient cities, complete streets, just cities, 15-minute cities, happy cities—rather than getting down to the actual work of designing the physical place. This lacks a fundamental vision. And it’s not succeeding.

Our flawed approach to city planning started a century ago. The first modern city plan was produced for Cincinnati in 1925 by the Technical Advisory Corporation, founded in 1913 by George Burdett Ford and E.P. Goodrich in New York City. New York adopted the country’s first comprehensive zoning ordinance in 1916, an effort Ford led. Not coincidentally, the advent of zoning, and then comprehensive planning, corresponded directly with the great migration of six million Black people from the South to Northern, Midwestern and Western cities. New city planning practices were a technical means to discriminate and exclude.

This first comprehensive plan also ushered in another type of dehumanization: city planning by formula. To justify widening downtown streets by cutting into sidewalks, engineers used a calculation that reflected the cost to operate an automobile in a congested area—including the cost of a human life, because crashes killed people. Engineers also calculated the value of a sidewalk through a formula based on how many people the elevators in adjoining buildings could deliver at peak times. In the end, Cincinnati’s planners recommended widening the streets for cars, which were becoming more common, by shrinking sidewalks. City planning became an engineering equation, and one focused on separating people and spreading the city out to the maximum extent possible…(More)”.

The City as a License: Design, Rights and Civics in a Blockchain Society

Curated on January 31, 2024February 1, 2024 by Stefaan Verhulst

Special Issue by Martijn de Waal et al: “Building upon critical work on smart cities, platform urbanism and algorithmic governance, this special issue proposes the ‘generative metaphor’ of the City as a License as a lens to analyze the digitally enhanced management of urban resources and infrastructures from a perspective of rights and agency. Such a perspective has become especially urgent with the rise of new data practices around the emergence of distributed ledger technologies, as they may introduce additional layers of complexity to the ‘algorithmic governance’ of cities. This is particularly due to their tokenization of resources, identities, and rights and automatic administration of access to urban resources. Contributions in this special issue investigate the affordances of distributed ledger technologies with regards to civic agency in the governance of collective urban resources. Could these newly emerging management systems for energy production and consumption or property rights contribute to pro-social and sustainable ways of governing and managing communities and their resources, according to the logic of the commons? The lens of the City as a License not only allows for such an analysis of potentialities, but also for a critical view on these techno-social systems, such as the way in which they may repeat the inequities and obfuscations of existing systems, produce unintended consequences through complex processes, and complicate accountability…(More)”.

The City of Today is a Dying Thing: In Search of the Cities of Tomorrow

Curated on January 27, 2024January 27, 2024 by Stefaan Verhulst

Book by Des Fitzgerald: “Cities are bad for us: polluted, noisy and fundamentally unnatural. We need green space, not concrete. Trees, not tower blocks. So goes the argument. But is it true? What would the city of the future look like if we tried to build a better life from the ground up? And would anyone want to live there?

Here, Des Fitzgerald takes us on an urgent, unforgettable journey into the future of urban life, from shimmering edifices in the Arizona desert to forest-bathing in deepest Wales, and from rats in mazes to neuroscientific studies of the effects of our surroundings. Along the way, he reveals the deep-lying and often controversial roots of today’s green city movement, and offers an argument for celebrating our cities as they are – in all their raucous, constructed and artificial glory…(More)”.

A tale of two cities: one real, one virtual

Curated on January 21, 2024January 21, 2024 by Stefaan Verhulst

Joy Lo Dico in the Financial Times: “In recent years, digital city-building has become a legitimate part of urban planning. Barcelona, Cambridge and Helsinki are among a number of European cities exploring how copies of themselves could prove useful in making their built environments sharper, faster, cleaner and greener.

What exists in real life is being rendered a second time in the digital space: creating a library of the past, an eagle’s-eye view of the present and, potentially, a vision of the future.

One of the most striking projects has been happening in Ukraine, where technology company Skeiron has, since 2022, been mapping the country’s monuments, under threat from bombing.

The project #SaveUkrainianHeritage has recorded 60 buildings, from the St Sofia Cathedral in Kyiv and the Chernivtsi National University — both Unesco world heritage sites — to wooden churches across the country, something Skeiron’s co-founder Yurii Prepodobnyi mentions with pride. There are thousands of them. “Some are only 20 or 30 square metres,” he says. “But Ukrainian churches keep Ukrainian identity.”

With laser measurements, drone photography and photogrammetry — the art of stitching photographs together — Prepodobnyi and his team can produce highly detailed 3D models.

They have even managed to recreate the exterior of the Mariupol drama theatre, destroyed in the early days of the Ukraine war, after calling for photographs and drone footage.

Another project, in Pompeii, has been using similar digital techniques to capture the evolution of excavations into a 3D model. The Pompeii I. 14 Project, led by Tulane University and Indiana State University, takes the process of excavating buildings within one block of Pompeii, Insula 14, and turns it into a digital representation. Using laser measurements, iPad Pros, a consumer drone and handheld cameras, a space can be measured to within a couple of millimetres. What is relayed back along the stream is a visual record of how a room changes over thousands of years, as the debris, volcanic eruption and layers of life that went before are revealed…(More)”.

Privacy and the City: How Data Shapes City Identities

Curated on January 13, 2024January 11, 2024 by Stefaan Verhulst

Article by Bilyana Petkova: “This article bridges comparative constitutional law to research inspired by city leadership and the opportunities that technology brings to the urban environment. It looks first to some of the causes of rapid urbanization and finds them in the pitfalls of antidiscrimination law in federations and quasi-federations such as the United States and the European Union. Short of achieving antidiscrimination based on nationality, the EU has experimented with data privacy as an identity clause that could bring social cohesion the same way purportedly freedom of speech has done in the US. In the City however, diversity replaces antidiscrimination, making cities attractive to migrants across various walks of life. The consequence for federalism is the obvious decline of top-down or vertical, state-based federalism and the rise of legal urbanism whereby cities establish loose networks of cooperation between themselves. These types of arrangements are not yet a threat to the State or the EU but might become such if cities are increasingly isolated from the political process (e.g. at the EU level) and lack legal means to assert themselves in court. City diversity and openness to different cultures in turn invites a connection to new technologies since unlike antidiscrimination that is usually strictly examined on a case-by-case level, diversity can be more readily computed. Finally, the article focuses on NYC and London initiatives to suggest a futuristic vision of city networks that instead of using social credit score like in China, deploy data trusts to populate their urban environments, shape city identities and exchange ideas for urban development…(More)”.

Artificial Intelligence and the City

Curated on December 9, 2023December 14, 2023 by Stefaan Verhulst

Book edited by Federico Cugurullo, Federico Caprotti, Matthew Cook, Andrew Karvonen, Pauline McGuirk, and Simon Marvin: “This book explores in theory and practice how artificial intelligence (AI) intersects with and alters the city. Drawing upon a range of urban disciplines and case studies, the chapters reveal the multitude of repercussions that AI is having on urban society, urban infrastructure, urban governance, urban planning and urban sustainability.

Contributors also examine how the city, far from being a passive recipient of new technologies, is influencing and reframing AI through subtle processes of co-constitution. The book advances three main contributions and arguments:

First, it provides empirical evidence of the emergence of a post-smart trajectory for cities in which new material and decision-making capabilities are being assembled through multiple AIs.
Second, it stresses the importance of understanding the mutually constitutive relations between the new experiences enabled by AI technology and the urban context.
Third, it engages with the concepts required to clarify the opaque relations that exist between AI and the city, as well as how to make sense of these relations from a theoretical perspective…(More)”.

Open data ecosystems: what models to co-create service innovations in smart cities?

Curated on December 5, 2023December 5, 2023 by Stefaan Verhulst

Paper by Arthur Sarazin: “While smart cities are recently providing open data, how to organise the collective creation of data, knowledge and related products and services produced from this collective resource, still remains to be thought. This paper aims at gathering the literature review on open data ecosystems to tackle the following research question: what models can be imagined to stimulate the collective co-creation of services between smart cities’ stakeholders acting as providers and users of open data? Such issue is currently at stake in many municipalities such as Lisbon which decided to position itself as a platform (O’Reilly, 2010) in the local digital ecosystem. With the implementation of its City Operation Center (COI), Lisbon’s municipality provides an Information Infrastructure (Bowker et al., 2009) to many different types of actors such as telecom companies, municipalities, energy utilities or transport companies. Through this infrastructure, Lisbon encourages such actors to gather, integrate and release heterogeneous datasets and tries to orchestrate synergies among them so data-driven solution to urban problems can emerge (Carvalho and Vale, 2018). The remaining question being: what models for the municipalities such as Lisbon to lean on so as to drive this cutting-edge type of service innovation?…(More)”.

Urban Artificial Intelligence: From Real-world Observations to a Paradigm-Shifting Concept

Curated on December 4, 2023December 6, 2023 by Stefaan Verhulst

Blog by Hubert Beroche: “Cities are facing unprecedented challenges. The figures are well known: while occupying only 2% of the earth’s surface, urban settlements host more than 50% of the global population and are responsible for 70% of greenhouse emissions. While concentrating most capital and human wealth, they are also places of systemic inequalities (Nelson, 2023), exacerbating and materializing social imbalances. In the meantime, cities have fewer and fewer resources to face those tensions. Increasing environmental constraints, combined with shrinking public budgets, are putting pressure on cities’ capacities. More than ever, urban stakeholders have to do more with less.

In this context, Artificial Intelligence has usually been seen as a much-welcomed technology. This technology can be defined as machines’ ability to perform cognitive functions, mainly through learning algorithms since 2012. First embedded in heavy top-down Smart City projects, AI applications in cities have gradually proliferated under the impetus of various stakeholders. Today’s cities are home to numerous AIs, owned and used by multiple stakeholders to serve different, sometimes divergent, interests.
