Urban Computing

Curated on Posted on by Stefaan Verhulst

Book by Yu Zheng:”…Urban computing brings powerful computational techniques to bear on such urban challenges as pollution, energy consumption, and traffic congestion. Using today’s large-scale computing infrastructure and data gathered from sensing technologies, urban computing combines computer science with urban planning, transportation, environmental science, sociology, and other areas of urban studies, tackling specific problems with concrete methodologies in a data-centric computing framework. This authoritative treatment of urban computing offers an overview of the field, fundamental techniques, advanced models, and novel applications.

Each chapter acts as a tutorial that introduces readers to an important aspect of urban computing, with references to relevant research. The book outlines key concepts, sources of data, and typical applications; describes four paradigms of urban sensing in sensor-centric and human-centric categories; introduces data management for spatial and spatio-temporal data, from basic indexing and retrieval algorithms to cloud computing platforms; and covers beginning and advanced topics in mining knowledge from urban big data, beginning with fundamental data mining algorithms and progressing to advanced machine learning techniques. Urban Computing provides students, researchers, and application developers with an essential handbook to an evolving interdisciplinary field….(More)”

The city as collective intelligence

Curated on Posted on by Stefaan Verhulst

Geoff Mulgan at Social Innovation Exchange: “As cities grow in size and significance, they can become sites of complex social problems – but also hubs for exploring possible solutions. While every city faces distinct problems, they all share a need for innovative approaches to tackle today’s challenges….

We all roughly know how our brains work. But what would a city look like that could truly think and act?  What if it could be fully aware of all of its citizens experiences; able to remember and create; and then to act and learn?

This might once have been a fantasy. But it is coming closer. Cities can see in new ways – with citizen generated data on everything from the prevalence of floods to the quality of food in restaurants. Cities can create in new ways, through open challenges that mobilise public creativity. And they can decide in new ways, as cities like Madrid and Barcelona have done with online platforms that let citizens propose policies and then deliberate. Some of this is helped by technology. Our mobile phones collect data on a vast scale, and that’s now matched by sensors and the smart chips in our cars, buildings and trains. But the best examples combine machine intelligence with human intelligence: this is the promise of collective intelligence, and it has obvious relevance to a city like Seoul with millions of smart citizens, fantastic infrastructures and very capable institutions, from government to universities, NGOs to business.

Over the last few years, many experiments have shown how thousands of people can collaborate online analysing data or solving problems, and there’s been an explosion of new technologies to sense, analyse and predict. We can see some of the results in things like Wikipedia; the spread of citizen science in which millions of people help to spot new stars in the galaxy. There are new business models like Duolingo which mobilises volunteers to improve its service providing language teaching, and collective intelligence examples in health, where patients band together to design new technologies or share data. 

I’m interested in how we can use these new kinds of collective intelligence to solve problems like climate change or disease, and am convinced that every organisation and every city can work more successfully if it taps into a bigger mind – mobilising more brains and computers to help it.  

Doing that requires careful design, curation and orchestration. It’s not enough just to mobilise the crowd. Crowds are all too capable of being foolish, prejudiced and malign. Nor it is enough just to hope that brilliant ideas will emerge naturally. Thought requires work – to observe, analyse, create, remember and judge and to avoid the many pitfalls of delusion and deliberate misinformation.

But the emerging field of collective intelligence now offers many ways for cities to organise themselves in new ways.

Take air quality as an example. A city using collective intelligence methods will bring together many different kinds of data to understand what’s happening to air, and the often complex patterns of particulates.  Some of this will come from its own sensors, and some data can be generated by citizens. Artificial intelligence tools can then be trained to predict how it may change, for example because of a shift in the weather. The next stage then is to mobilise citizens and experts to investigate the options to improve air quality looking in detail at which roads have the worst levels or which buildings are emitting the most, and what changes would have most impact. And finally cities can open up the process of learning, seeing what’s working and what’s not….(More)”.

This website can tell what kind of person you are based on where you live. See for yourself what your ZIP code says about you

Curated on Posted on by Stefaan Verhulst

Meira Geibel at Business Insider:

  • “Esri’s Tapestry technology includes a ZIP code look-up feature where you can see the top demographics, culture, and lifestyle choices in your area.
  • Each ZIP code shows a percentage breakdown of Esri’s 67 unique market-segment classifications with kitschy labels like “Trendsetters” and “Savvy Suburbanites.”
  • The data can be altered to show median age, population density, people with graduate and professional degrees, and the percentage of those who charge more than $1,000 to their credit cards monthly.

Where you live says a lot about you. While you’re not totally defined by where you go to sleep at night, you may have more in common with your neighbors than you think.

That’s according to Esri, a geographic-information firm based in California, which offers a “ZIP Lookup” feature. The tool breaks down the characteristics of the individuals in a given neighborhood by culture, lifestyle, and demographics based on data collected from the area.

The data is then sorted into 67 unique market-segment classifications that have rather kitschy titles like “Trendsetters” and “Savvy Suburbanites.”

You can try it for yourself: Just head to the website, type in your ZIP code, and you’ll be greeted with a breakdown of your ZIP code’s demographic characteristics….(More)”.

The Internet of Humans (IoH): Human Rights and Co-Governance to Achieve Tech Justice in the City

Curated on Posted on by Stefaan Verhulst

Paper by Christian Iaione, Elena de Nictolis and Anna Berti Suman: “Internet of Things, Internet of Everything and Internet of People are concepts suggesting that objects, devices and people will be increasingly interconnected through digital infrastructure that will generate a growing gathering of data. Parallel to this is the celebration of the smart city and sharing city as urban policy visions that by relying heavily on new technologies bear the promise of a efficient and thriving cities. Law and policy scholarship has either focused on questions related to privacy, discrimination, security or issues related to the production and use of big data, digital public services. Little or no attention in the literature has been paid to the disruptive impact of technological development on urban governance and city inhabitants’ rights of equal access, participation, management and even ownership, in order to understand whether and how technology can also enhance the protection of human rights and social justice in the city.

This article advances the proposal of complementing the technological and digital infrastructure with a legal and institutional infrastructure, the Internet of Humans, by construing and injecting in the legal and policy framework of the city the principle of Tech Justice. Building on the literature review on and from the analysis of selected case studies this article stresses the dichotomy existing between the market-based and the society-based applications of technology, the first likely to increase the digital divide and the challenges to human rights in the city, the latter bearing the promise to promote equal access to technology in the city. The main argument advanced by this paper is indeed that Tech Justice is an empirical dimension that can steer the developments of smart city and sharing city policies toward a more just and democratic city….(More)”.

Is Gamification Making Cities Smarter?

Curated on Posted on by Stefaan Verhulst

Gianluca Sgueo in Ius Publicum Network Review: Streets embedded with sensors to manage traffic congestion, public spaces monitored by high-tech command centres to detect suspicious activities, real-time and publicly accessible data on energy, transportation and waste management – in academia, there is still no generally agreed definition of ‘smart cities’. But in the collective imagination, the connotations are clear: smart cities are seen as efficient machines governed by algorithms. For decades, the combination of technology and data has been a key feature of smart urban management. Under this scheme, what branded a city as smart was the efficiency of (digital) public services. Over time, concerns have grown over this privatization of public services. Who owns the data processed by private companies? Who guarantees that data are treated ethically? How inclusive are the public services provided by increasingly privatised smart cities? 

In response to such criticism, urban management has progressively shifted the focus from the efficiency of public services to citizens’ concerns. This new approach puts inclusiveness at the centre of public services design. Citizens are actively engaged in all phases of urban management, from planning to service provision. However, the quest for inclusive urban management is confronted by four challenges. The first is dimensional, the second regulatory, the third financial, and the fourth relational.

The moment we combine these four challenges together, uncertainty arises: can a smart city be inclusive at the same time? It goes beyond the scope of this article to thoroughly delve into this question. My aim is to contribute to reflections on where the quest for inclusiveness is leading smart urban management. To this end, this article focuses on one specific form of innovative urban management: a combination of technology and fun design described as ‘gamification’.

The article reviews the use of gamification at the municipal level. After describing seven case studies of gamified urban governance, it analyses three shared traits of these initiatives, namely: the structure, the design, and the purposes. It then discusses the (potential) benefits and (actual) drawbacks of gamification in urban environments. The article concludes by assessing the contribution that gamification is making to the evolution of smart cities. It is argued that gamification offers a meaningful solution to more inclusive urban decision-making. But it is also warned about three common misconceptions in discourses on the future of smart cities. The first is the myth of inclusive technology; the second consists of the illusion of the democratic potential of games; finally, the third points at the downsides of regulatory experimentalism….(More)”.

New Urban Centres Database sets new standards for information on cities at global scale

Curated on Posted on by Stefaan Verhulst

EU Science Hub: “Data analysis highlights very diverse development patterns and inequalities across cities and world regions.

Building on the Global Human Settlement Layer (GHSL), the new database provides more detailed information on the cities’ location and size as well as characteristics such as greenness, night time light emission, population size, the built-up areas exposed to natural hazards, and travel time to the capital city.

For several of these attributes, the database contains information recorded over time, dating as far back as 1975. 

Responding to a lack of consistent data, or data only limited to large cities, the Urban Centre Database now makes it possible to map, classify and count all human settlements in the world in a standardised way.

An analysis of the data reveals very different development patterns in the different parts of the world.

“The data shows that in the low-income countries, high population growth has resulted only into moderate increases in the built-up areas, while in the high-income countries, moderate population growth has resulted into very big increases in the built-up areas. In practice, cities have grown more in size in richer countries, with respect to poorer countries where the populations are growing faster”, said JRC researcher Thomas Kemper.

According to JRC scientists, around 75% of the global population now live in cities, towns or suburbs….

The City Centres Database provides new open data supporting the monitoring of UN Sustainable Development Goals, the UN’s New Urban Agenda and the Sendai Framework for Disaster Risk Reduction.

The main findings based on the Urban Centre Database are summarised in a new edition of the Atlas of the Human Planet, published together with the database….(More)”.

People-led innovation project to help tackle policy challenges

Curated on Posted on by Stefaan Verhulst

Natalie Leal at Global Government Forum: “A new initiative by two US think tanks aims to help public bodies explore innovative ways of consulting and engaging with communities, finding new answers to public policy challenges. 

The People-Led Innovation project was launched on Tuesday by GovLab and the Bertelsmann Foundation. Noting that citizens’ knowledge, insights and ideas often hold the key to the problems faced by governments, GovLab co-founder Stefaan Verhulst said the new tools will help officials consider “the most effective ways to engage the right people for the right task at the right time.”

Verhulst explained that the initiative, ‘People-Led Innovation: Toward a Methodology for Solving Urban Problems in the 21st Century’, is “built on the idea that, as governments increasingly experiment with new means for drawing on the public’s knowledge and skills to address common challenges, one-size-fits-all citizen engagement efforts are often too broad and unwieldy to surface useful insights.”

A fresh methodology

The new site aims to provide leaders with a toolkit and “a set of steps that enable them to tap into their potentially most important – but underutilized – asset: people.” While the project’s main audience is US city governments, the skills and methodology are transferable and the researchers have drawn on case studies from around the world.

The methodology breaks the process down into four distinct stages: defining the problem; curating possible solutions using people and data; experimenting and testing what works in practice; and reviewing and ‘expanding’ – incorporating feedback and transferring lessons learned to a wider audience. At each stage, leaders are encouraged to identify stakeholders to consult or co-create with. 

At the heart of the initiative is the idea that everyone – from local residents, small businesses and community bodies through to government agencies, corporate giants and international organisations – can contribute valuable ideas and help solve complex problems....

“People’s expertise comes in a range of flavours – from interests and experiences to skills and credentialed knowledge – yet all are equally valuable to engage when solving problems,” say the creators in a report on the website. 

Four types of engagement methods are suggested as ways to best “tap into the diverse expertise distributed among people outside of government. These are: commenting, for example a discussion platform to gather views, experiences and opinions; co-creating, e.g. a sector-specific hackathon to leverage datasets; reviewing, including online or offline engagements allowing people to vote on specific proposals or ideas; and reporting, e.g. a crowdsourcing platform for citizens to record incidents of problematic issues such as potholes or graffiti….(More)”.

This Startup Is Challenging Google Maps—and It Needs You

Curated on Posted on by Stefaan Verhulst

Aarian Marshall at Wired: “A whole lifetime in New York City, and Christiana Ting didn’t realize just how many urgent care facilities there were until the app told her to start looking for them. “They were giving extra points for medical offices, and I found them, I think, on every block,” she says. “I’m not sure what that says about the neighborhood where I work.”

Ting was one of 761 New Yorkers who downloaded, played with, and occasionally became obsessed with an app called MapNYC this fall, vying for their share of an 8-bitcoin prize (worth about $50,000 at the time). The month-long contest, run by a new mapping startup called StreetCred, was really an experiment. StreetCred’s main research question: How do you convince regular people to build and verify mappingdata?

It turns out that the maps that guide you to the nearest Arby’s, or help your Lyft driver find your house, don’t just materialize. “I took mapping for granted until I started the competition,” Ting says, even though she pulls up Google Maps at least twice a day. “But it’s such an inconvenience if the info on the map is wrong, especially in a place like New York, that’s changing all the time.”

For regular folk, detailed, reliable mapping info is helpful. For businesses, it can be crucial. Some want to be found when a map user searches for the nearest sandwich shop. Others use products that rely on base maps—think Uber, the Weather Channel, your car’s navigation system—and require up-to-date location data. “One of the huge challenges to any geographic database is its currency,” says Renee Sieber, a geographer who studies participatory mapping at McGill University. That is to say, yesterday’s map is no good to anybody doing business today.

StreetCred sees that as an opportunity. “There’s a lot of companies, none of whom I can name, who have location data, and that data needs improvement,” says Randy Meech, CEO of the small startup. (Meech’s last open-source mapping company, a Samsung subsidiary called Mapzen, shut down in January.) Maybe a client found a data set online or purchased one from another company. Either way, it’s static, and that means it’s only a matter of time before it fails to represent reality.

Google Maps, the giant in this space, has created its extensive database through years of web scraping, Streetview roaming, purchasing and collecting satellite data, and both paying and asking volunteers to verify that the businesses it identifies are still in the same place. But the company doesn’t provide all of its specific location or “point of interest” data to developers—where that Thai restaurant is, or where the hiking trail starts, or where the hospital parking lot is located. When it and other mapping services like HERE Technologies, TomTom, and Foursquare do offer that intel, it can be pricey. StreetCred wants to make that info free for customers who don’t need that much data and cheaper for those that do….(More)”.

The Urban Commons: How Data and Technology Can Rebuild Our Communities

Curated on Posted on by Stefaan Verhulst

Book by Daniel T. O’Brien: “The future of smart cities has arrived, courtesy of citizens and their phones. To prove it, Daniel T. O’Brien explains the transformative insights gleaned from years researching Boston’s 311 reporting system, a sophisticated city management tool that has revolutionized how ordinary Bostonians use and maintain public spaces. Through its phone service, mobile app, website, and Twitter account, 311 catalogues complaints about potholes, broken street lights, graffiti, litter, vandalism, and other issues that are no one citizen’s responsibility but affect everyone’s quality of life. The Urban Commons offers a pioneering model of what modern digital data and technology can do for cities like Boston that seek both prosperous growth and sustainability.

Analyzing a rich trove of data, O’Brien discovers why certain neighborhoods embrace the idea of custodianship and willingly invest their time to monitor the city’s common environments and infrastructure. On the government’s side of the equation, he identifies best practices for implementing civic technologies that engage citizens, for deploying public services in collaborative ways, and for utilizing the data generated by these efforts.

Boston’s 311 system has narrowed the gap between residents and their communities, and between constituents and local leaders. The result, O’Brien shows, has been the creation of more effective policy and practices that reinvigorate the way citizens and city governments approach their mutual interests. By unpacking when, why, and how the 311 system has worked for Boston, The Urban Commons reveals the power and potential of this innovative system, and the lessons learned that other cities can adapt…(More)”.

Smart cities could be lousy to live in if you have a disability

Curated on Posted on by Stefaan Verhulst

Elizabeth Woyke in MIT Technology Review: “People with disabilities affecting mobility, vision, hearing, and cognitive function often move to cities to take advantage of their comprehensive transit systems and social services. But US law doesn’t specify how municipalities should design and implement digital services for disabled people. As a result, cities sometimes adopt new technologies that can end up causing, rather than resolving, problems of accessibility.

Nowhere was this more evident than with New York City’s LinkNYC kiosks, which were installed on sidewalks in 2016 without including instructions in Braille or audible form. Shortly after they went in, the American Federation for the Blind sued the city. The suit was settled in 2017 and the kiosks have been updated, but Pineda says touch screens in general are still not fully accessible to people with disabilities.

Also problematic: the social-media-based apps that some municipal governments have started using to solicit feedback from residents. Blind and low-vision people typically can’t use the apps, and people over 65 are less likely to, says James Thurston, a vice president at the nonprofit G3ict, which promotes accessible information and communication technologies. “Cities may think they’re getting data from all their residents, but if those apps aren’t accessible, they’re leaving out the voices of large chunks of their population,” he says….

Even for city officials who have these issues on their minds, knowing where to begin can be difficult. Smart Cities for All, an initiative led by Thurston and Pineda, aims to help by providing free, downloadable tools that cities can use to analyze their technology and find more accessible options. One is a database of hundreds of pre-vetted products and services. Among the entries are Cyclomedia, which uses lidar data to determine when city sidewalks need maintenance, and ZenCity, a data analytics platform that uses AI to gauge what people are saying about a city’s level of accessibility. 

This month, the group will kick off a project working with officials in Chicago to grade the city on how well it supports people with disabilities. One key part of the project will be ensuring the accessibility of a new 311 phone system being introduced as a general portal to city services. The group has plans to expand to several other US cities this year, but its ultimate aim is to turn the work into a global movement. It’s met with governments in India and Brazil as well as Sidewalk Labs, the Alphabet subsidiary that is developing a smart neighborhood in Toronto….(More)”.
