How cities can flex their purchasing power to stimulate innovation


Article by Sam Markey and Andrew Watkins: “But the “power of the purse” can be a game-changer. City governments spend $6 trillion annually buying goods and services from private sector suppliers, amounting to 8% of world GDP in 2021. These delivery contracts represent a huge commercial opportunity for suppliers, but also a policy tool for local authorities to shape markets and steer private sector research and development…

In recent years, local and national leaders have been rediscovering the power of public procurement and dismantling the legislative and cultural barriers that have limited its potential. Analysis by the OECD endorsed public procurement as a strategic instrument that can be used by government to promote innovation, facilitate diversity of thought and address societal challenges

A growing number of city authorities are using these powers to drive not just delivery but transformation:

  • Faced with the challenge of waste collection from properties using narrow rear alleys as a dumping ground, Liverpool City Council (UK) used an innovation-friendly procurement approach to engage the market, and identify, evaluate and integrate a new solution. Installing communal waste collection points with below-surface storage restored the alleys to being community spaces, promoting a sense of belonging and neighbourliness. Clearly marked disposal points for recycling saw adoption rise by 270%, while new ways of working saw the cost of collection fall from £56 to £32 per property, and a carbon footprint reduction of 60%.
  • In Norway, where ferries provide vital transport infrastructure and are therefore largely operated as public services, regional governments require that all new ferry contracts must use low-emission technologies where possible. This market pull has seen electric-powered ferries replace diesel ferries, cutting emissions by 95% and costs by 80%.
  • As part of an ambitious Green New Deal that aims to electrify 6,000 properties in Ithaca, New York State, the city secured a 30% discount on the cost of heat pumps and other retrofit technologies by orchestrating demand into an advance bulk purchase.
  • Through the YES San Francisco Urban Sustainability Challenge, the City of San Francisco is partnering with the public-private sector to launch 14 new technologies to be deployed locally to support sustainability goals…(More)”.

DC launched an AI tool for navigating the city’s open data


Article by Kaela Roeder: “In a move echoing local governments’ increasing attention toward generative artificial intelligence across the country, the nation’s capital now aims to make navigating its open data easier through a new public beta pilot.

DC Compass, launched in March, uses generative AI to answer user questions and create maps from open data sets, ranging from the district’s population to what different trees are planted in the city. The Office of the Chief Technology Officer (OCTO) partnered with the geographic information system (GIS) technology company Esri, which has an office in Vienna, Virginia, to create the new tool.

This debut follows Mayor Muriel Bowser’s signing of DC’s AI Values and Strategic Plan in February. The order requires agencies to assess if using AI is in alignment with the values it sets forth, including that there’s a clear benefit to people; a plan for “meaningful accountability” for the tool; and transparency, sustainability, privacy and equity at the forefront of deployment.

These values are key when launching something like DC Compass, said Michael Rupert, the interim chief technology officer for digital services at the Office of the Chief Technology Officer.

“The way Mayor Bowser rolled out the mayor’s order and this value statement, I think gives residents and businesses a little more comfort that we aren’t just writing a check and seeing what happens,” Rupert said. “That we’re actually methodically going about it in a responsible way, both morally and fiscally.”..(More)”.

Designing Digital Voting Systems for Citizens


Paper by Joshua C. Yang et al: “Participatory Budgeting (PB) has evolved into a key democratic instrument for resource allocation in cities. Enabled by digital platforms, cities now have the opportunity to let citizens directly propose and vote on urban projects, using different voting input and aggregation rules. However, the choices cities make in terms of the rules of their PB have often not been informed by academic studies on voter behaviour and preferences. Therefore, this work presents the results of behavioural experiments where participants were asked to vote in a fictional PB setting. We identified approaches to designing PB voting that minimise cognitive load and enhance the perceived fairness and legitimacy of the digital process from the citizens’ perspective. In our study, participants preferred voting input formats that are more expressive (like rankings and distributing points) over simpler formats (like approval voting). Participants also indicated a desire for the budget to be fairly distributed across city districts and project categories. Participants found the Method of Equal Shares voting rule to be fairer than the conventional Greedy voting rule. These findings offer actionable insights for digital governance, contributing to the development of fairer and more transparent digital systems and collective decision-making processes for citizens…(More)”.

AI-Powered Urban Innovations Bring Promise, Risk to Future Cities


Article by Anthony Townsend and Hubert Beroche: “Red lights are obsolete. That seems to be the thinking behind Google’s latest fix for cities, which rolled out late last year in a dozen cities around the world, from Seattle to Jakarta. Most cities still collect the data to determine the timing of traffic signals by hand. But Project Green Light replaced clickers and clipboards with mountains of location data culled from smartphones. Artificial intelligence crunched the numbers, adjusting the signal pattern to smooth the flow of traffic. Motorists saw 30% fewer delays. There’s just one catch. Even as pedestrian deaths in the US reached a 40-year high in 2022, Google engineers omitted pedestrians and cyclists from their calculations.

Google’s oversight threatens to undo a decade of progress on safe streets and is a timely reminder of the risks in store when AI invades the city. Mayors across global cities have embraced Vision Zero pledges to eliminate pedestrian deaths. They are trying to slow traffic down, not speed it up. But Project Green Light’s website doesn’t even mention road safety. Still, the search giant’s experiment demonstrates AI’s potential to help cities. Tailpipe greenhouse gas emissions at intersections fell by 10%. Imagine what AI could do if we used it to empower people in cities rather than ignore them.

Take the technocratic task of urban planning and the many barriers to participation it creates. The same technology that powers chatbots and deepfakes is rapidly bringing down those barriers. Real estate developers have mastered the art of using glossy renderings to shape public opinion. But UrbanistAI, a tool developed by Helsinki-based startup SPIN Unit and the Milanese software company Toretei, puts that power in the hands of residents: It uses generative AI to transform text prompts into photorealistic images of alternative designs for controversial projects. Another startup, the Barcelona-based Aino, wraps a chatbot around a mapping tool. Using such computer aids, neighborhood activists no longer need to hire a data scientist to produce maps from census data to make their case…(More)”.

The Computable City: Histories, Technologies, Stories, Predictions


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


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


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


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


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)”.
