How to use mobile phone data for good without invading anyone’s privacy

Curated on Posted on by Stefaan Verhulst

Leo Mirani in Quartz: “In 2014, when the West African Ebola outbreak was at its peak, some academics argued that the epidemic could have been slowed by using mobile phone data.

Their premise was simple: call-data records show the true nature of social networks and human movement. Understanding social networks and how people really move—as seen from phone movements and calls—could give health officials the ability to predict how a disease will move and where a disease will strike next, and prepare accordingly.

The problem is that call-data records are very hard to get a hold of. The files themselves are huge, there are enormous privacy risks, and the process of making the records safe for distribution is long.
First, the technical basics

Every time you make a phone call from your mobile phone to another mobile phone, the network records the following information (note: this is not a complete list):

  • The number from which the call originated
  • The number at which the call terminated
  • Start time of the call
  • Duration of the call
  • The ID number of the phone making the call
  • The ID number of the SIM card used to make the call
  • The code for the antenna used to make the call

On their own, these records are not creepy. Indeed, without them, networks would be unable to connect calls or bill customers. But it is easy to see why operators aren’t rushing to share this information. Even though the data includes none of the actual content of a phone call in the data, simply knowing which number is calling which, and from where and when, is usually more than enough to identify people.
So how can network operators use this valuable data for good while also protecting their own interests and those of their customers? A good example can be found in Africa, where Orange, a French mobile phone network with interests across several African countries, has for the second year run its “Data for Development” (D4D) program, which offers researchers a chance to mine call data for clues on development problems.

Steps to safe sharing

After a successful first year in Ivory Coast, Orange this year ran the D4D program in Senegal. The aim of the program is to give researchers and scientists at universities and other research labs access to data in order to find novel ways to aid development in health, agriculture, transport or urban planning, energy, and national statistics….(More)”

India asks its citizens: please digitise our files

Curated on Posted on by Stefaan Verhulst

Joshua Chambers in FutureGov: “India has asked its citizens to help digitise records so that it can move away from paper processes.

Using its crowdsourcing web site MyGov, the government wrote that “we cannot talk of Digital India and transforming India into a knowledge society if most of the transactions continue to be physical.”

It is “essential” that paper records are converted into machine readable digital versions, the government added, but “the cost of such digitisation is very large and existing budgetary constraints of government and many other organisations do not allow such lavish digitisation effort.”

Consequently, the government is asking citizens for advice on how to build a cheap content management system and tools that will allow it to crowdsource records transcriptions. Citizens would be rewarded for every word that they transcribe through a points system, which can then be recouped into cash prizes.

“The proposed platform will create earning and income generation opportunities for our literate rural and urban citizens, develop digital literacy and IT skills and include them in the making of Digital India,” the government added.

The announcement also noted the importance of privacy, suggesting that documents are split so that no portion gives any clue regarded the overall content of the document.

Instead, two people will be given the same words to transcribe, and the software will compare their statements to ensure accuracy. Only successful transcription will be rewarded with points….(More)”

Governing the smart city: a review of the literature on smart urban governance

Curated on Posted on by Stefaan Verhulst

Review by Albert Meijer and Manuel Pedro Rodríguez Bolívar in International Review of Administrative Sciences: “Academic attention to smart cities and their governance is growing rapidly, but the fragmentation in approaches makes for a confusing debate. This article brings some structure to the debate by analyzing a corpus of 51 publications and mapping their variation. The analysis shows that publications differ in their emphasis on (1) smart technology, smart people or smart collaboration as the defining features of smart cities, (2) a transformative or incremental perspective on changes in urban governance, (3) better outcomes or a more open process as the legitimacy claim for smart city governance. We argue for a comprehensive perspective: smart city governance is about crafting new forms of human collaboration through the use of ICTs to obtain better outcomes and more open governance processes. Research into smart city governance could benefit from previous studies into success and failure factors for e-government and build upon sophisticated theories of socio-technical change. This article highlights that smart city governance is not a technological issue: we should study smart city governance as a complex process of institutional change and acknowledge the political nature of appealing visions of socio-technical governance….(More)”

Urban Data Games: creating smart citizens for smart cities

Curated on Posted on by Stefaan Verhulst

Paper by Wolff, Annika; Kortuem, Gerd and Cavero, Jose: “A bottom-up approach to smart cities places citizens in an active role of contributing, analysing and interpreting data in pursuit of tackling local urban challenges and building a more sustainable future city. This vision can only be realised if citizens have sufficient data literacy skills and experience of large, complex, messy, ever expanding data sets. Schools typically focus on teaching data handling skills using small, personally collected data sets obtained through scientific experimentation, leading to a gap between what is being taught and what will be needed as big data and analytics become more prevalent. This paper proposes an approach to teaching data literacy in the context of urban innovation tasks, using an idea of Urban Data Games. These are supported by a set of training data and resources that will be used in school trials for exploring the problems people have when dealing with large data and trialling novel approaches for teaching data literacy….(More)”

How Crowdsourcing And Machine Learning Will Change The Way We Design Cities

Curated on Posted on by Stefaan Verhulst

Shaunacy Ferro at FastCompany: “In 2011, researchers at the MIT Media Lab debuted Place Pulse, a website that served as a kind of “hot or not” for cities. Given two Google Street View images culled from a select few cities including New York City and Boston, the site asked users to click on the one that seemed safer, more affluent, or more unique. The result was an empirical way to measure urban aesthetics.

Now, that data is being used to predict what parts of cities feel the safest. StreetScore, a collaboration between the MIT Media Lab’s Macro Connections and Camera Culture groups, uses an algorithm to create a super high-resolution map of urban perceptions. The algorithmically generated data could one day be used to research the connection between urban perception and crime, as well as informing urban design decisions.

The algorithm, created by Nikhil Naik, a Ph.D. student in the Camera Culture lab, breaks an image down into its composite features—such as building texture, colors, and shapes. Based on how Place Pulse volunteers rated similar features, the algorithm assigns the streetscape a perceived safety score between 1 and 10. These scores are visualized as geographic points on a map, designed by MIT rising sophomore Jade Philipoom. Each image available from Google Maps in the two cities are represented by a colored dot: red for the locations that the algorithm tags as unsafe, and dark green for those that appear safest. The site, now limited to New York and Boston, will be expanded to feature Chicago and Detroit later this month, and eventually, with data collected from a new version of Place Pulse, will feature dozens of cities around the world….(More)”

Knight Cities Challenge Winners

Carol Coletta at Knight Foundation: “32 civic innovators receive $5 million in funding in first Knight Cities Challenge…

Several themes emerged among the winning applications, which all sought to accelerate talent, opportunity or engagement—the three primary drivers of city success—in some way. “Bringing life back to public and vacant space” was the theme of our largest category of winners, representing almost a third of the group. The second largest category was “changing the stories people tell about their cities” with almost 20 percent. Three more themes each represented 13 percent of the winning ideas: “reimagining the civic commons,” “retaining talent” and “promoting civic engagement.” A full list of the winners appears below….

Mission Control: A History of the Urban Dashboard

Curated on Posted on by Stefaan Verhulst

Shannon Mattern at Places: “We know what rocket science looks like in the movies: a windowless bunker filled with blinking consoles, swivel chairs, and shirt-sleeved men in headsets nonchalantly relaying updates from “Houston” to outer space. Lately, that vision of Mission Control has taken over City Hall. NASA meets Copacabana, proclaimed the New York Times, hailing Rio de Janeiro’s Operations Center as a “potentially lucrative experiment that could shape the future of cities around the world.” The Times photographed an IBM executive in front of a seemingly endless wall of screens integrating data from 30 city agencies, including transit video, rainfall patterns, crime statistics, car accidents, power failures, and more. 1

Futuristic control rooms have proliferated in dozens of global cities. Baltimore has its CitiStat Room, where department heads stand at a podium before a wall of screens and account for their units’ performance.  The Mayor’s office in London’s City Hall features a 4×3 array of iPads mounted in a wooden panel, which seems an almost parodic, Terry Gilliam-esque take on the Brazilian Ops Center. Meanwhile, British Prime Minister David Cameron commissioned an iPad app – the “No. 10 Dashboard” (a reference to his residence at 10 Downing Street) – which gives him access to financial, housing, employment, and public opinion data. As The Guardian reported, “the prime minister said that he could run government remotely from his smartphone.”

This is the age of Dashboard Governance, heralded by gurus like Stephen Few, founder of the “visual business intelligence” and “sensemaking” consultancy Perceptual Edge, who defines the dashboard as a “visual display of the most important information needed to achieve one or more objectives; consolidated and arranged on a single screen so the information can be monitored at a glance.” A well-designed dashboard, he says — one that makes proper use of bullet graphs, sparklines, and other visualization techniques informed by the “brain science” of aesthetics and cognition — can afford its users not only a perceptual edge, but a performance edge, too. The ideal display offers a big-picture view of what is happening in real time, along with information on historical trends, so that users can divine the how and why and redirect future action. As David Nettleton emphasizes, the dashboard’s utility extends beyond monitoring “the current situation”; it also “allows a manager to … make provisions, and take appropriate actions.”….

The dashboard market now extends far beyond the corporate world. In 1994, New York City police commissioner William Bratton adapted former officer Jack Maple’s analog crime maps to create the CompStat model of aggregating and mapping crime statistics. Around the same time, the administrators of Charlotte, North Carolina, borrowed a business idea — Robert Kaplan’s and David Norton’s “total quality management” strategy known as the “Balanced Scorecard” — and began tracking performance in five “focus areas” defined by the City Council: housing and neighborhood development, community safety, transportation, economic development, and the environment. Atlanta followed Charlotte’s example in creating its own city dashboard.

In 1999, Baltimore mayor Martin O’Malley, confronting a crippling crime rate and high taxes, designed CitiStat, “an internal process of using metrics to create accountability within his government.” (This rhetoric of data-tested internal “accountability” is prevalent in early dashboard development efforts.) The project turned to face the public in 2003, when Baltimore launched a website of city operational statistics, which inspired DCStat (2005), Maryland’s StateStat (2007), and NYCStat (2008). Since then, myriad other states and metro areas — driven by a “new managerialist” approach to urban governance, committed to “benchmarking” their performance against other regions, and obligated to demonstrate compliance with sustainability agendas — have developed their own dashboards.

The Open Michigan Mi Dashboard is typical of these efforts. The state website presents data on education, health and wellness, infrastructure, “talent” (employment, innovation), public safety, energy and environment, financial health, and seniors. You (or “Mi”) can monitor the state’s performance through a side-by-side comparison of “prior” and “current” data, punctuated with a thumbs-up or thumbs-down icon indicating the state’s “progress” on each metric. Another click reveals a graph of annual trends and a citation for the data source, but little detail about how the data are actually derived. How the public is supposed to use this information is an open question….(More)”

Citizens Connect

Curated on Posted on by Stefaan Verhulst

Harvard Business School Case Study by Mitchell Weiss: “Funding to scale Citizens Connect, Boston’s 311 app, is both a blessing and a burden and tests two public entrepreneurs. In 2012, the Commonwealth of Massachusetts provides Boston’s Mayor’s Office of New Urban Mechanics with a grant to scale Citizens Connect across the state. The money gives two co-creators of Citizens Connect, Chris Osgood and Nigel Jacob, a chance to grow their vision for citizen-engaged governance and civic innovation, but it also requires that the two City of Boston leaders sit on a formal selection committee that pits their original partner, Connected Bits, against another player that might meet the specific requirements for delivering a statewide version. The selection and scaling process raise questions beyond just which partner to choose. What would happen to the Citizens Connect brand as Osgood and Jacob’s product spreads across the state? Who could help scale their work best then nationally? Which business models were best positioned to drive that growth? What intellectual property arrangements would best enable it? And what role should the two city employees have, anyway, in scaling Citizens Connect outside of Boston in the first place? These questions hung in the air as they pondered the one big one about passing over Connected Bits for another partner: should they?…(More)”

Action-Packed Signs Could Mean Fewer Pedestrian Accidents

Curated on Posted on by Stefaan Verhulst

Marielle Mondon at Next City: “Action-packed road signs could mean less unfortunate action for pedestrians. More than a year after New York and San Francisco implemented Vision Zero campaigns to increase pedestrian safety, new research shows that warning signs depicting greater movement — think running stick figures, not walking ones — cause fewer pedestrian accidents.
“A sign that evokes more perceived movement increases the observer’s perception of risk, which in turn brings about earlier attention and earlier stopping,” said Ryan Elder, co-author of the new Journal of Consumer Research report. “If you want to grab attention, you need signs that are more dynamic.”

The real U.S. pedestrian sign on the left represents what almost seems to be a casual stroll, while the example on the far right amps up the speed of the walkers.

The study argues that drivers react faster to signs showing greater movement because the threat of a last-minute accident seems more real — and often, a quicker reaction, even by a few seconds, can make a major difference….
Another important point in a world where pedestrians can play games with walk signals: Elder’s suggestions seem more noteworthy than whimsical — and not necessarily a contribution to urban cutesification that annoys some city-dwellers….(More)”
