Using Open Data to Analyze Urban Mobility from Social Networks


Paper by Caio Libânio Melo Jerônimo, Claudio E. C. Campelo, Cláudio de Souza Baptista: “The need to use online technologies that favor the understanding of city dynamics has grown, mainly due to the ease in obtaining the necessary data, which, in most cases, are gathered with no cost from social networks services. With such facility, the acquisition of georeferenced data has become easier, favoring the interest and feasibility in studying human mobility patterns, bringing new challenges for knowledge discovery in GIScience. This favorable scenario also encourages governments to make their data available for public access, increasing the possibilities for data scientist to analyze such data. This article presents an approach to extracting mobility metrics from Twitter messages and to analyzing their correlation with social, economic and demographic open data. The proposed model was evaluated using a dataset of georeferenced Twitter messages and a set of social indicators, both related to Greater London. The results revealed that social indicators related to employment conditions present higher correlation with the mobility metrics than any other social indicators investigated, suggesting that these social variables may be more relevant for studying mobility behaviors….(More)”.

Mobility Score


MobilityScore® helps you understand how easy it is to get around. It works at any location or address within the US and Canada and gives you a score ranging from 0 (no mobility choices) to 100 (excellent mobility choices).

What do we mean by mobility? Any transportation option that can help you move around your city. Transportation is changing massively as new choices emerge: ridesharing, bikesharing, carsharing. Private and on-demand mobility services have sprung up. However, tools for measuring transportation access have not kept up. That’s why we created MobilityScore as an easy-to-understand measure of transportation access.

Technical Details

MobilityScore includes all the transportation choices that can be found on TransitScreen displays, including the following services:

  • Public transit (subways, trains, buses, ferries, cable cars…)
  • Car sharing services (Zipcar, Enterprise, and one-way services like car2go)
  • Bike sharing services
  • Hailed ride sharing services (e.g. taxis, Uber, Lyft)

We have developed a common way of comparing how choices that might seem very different contribute to your mobility. For each mobility choice, we measure how long it will take you until you can start moving on it – for example, the time it takes you to leave your building, walk to a subway station, and wait for a train.

Because we’re measuring how easy it is for you to move around the city, we also consider what mobility choices look like at different times of the day and different days of the week. Mobility data is regularly collected for most services, while ridehailing (Uber/Lyft) data is based on a geographic model of arrival times.

MobilityScore’s framework is future-proof. Just like we do with TransitScreen, we will integrate future services into the calculation as they emerge (e.g. microtransit, autonomous vehicles, mobility-as-a-service)….(More)”

New program wants to improve cities with the power of tweets and Flickr uploads


Marissa Clifford at Curbed: “Want to watch street life unfold outside of New York’s Metropolitan Museum of Art, long after it’s closed for the day? Or uncover the hidden ways both tourists and locals alike use Manhattan’s most famous landmarks? Now you can, all thanks to the power of data.

Urban Pulse, open-source software developed at NYU’s Tandon School of Engineering, uses data to create a map that visualizes how people move through cities. From Urban Pulse’s interface, you can observe, for example, how tourists navigate Central Park.

Sociologists Robert Park and Ernest Burgess, who worked in the early years of the 20th century, developed a theory of urban environments that used the human body as an organizing analogy: They likened the mundane processes of everyday urban life (things like phone calls and taxi rides) to the heartbeat. Urban Pulse brings that analogy into the 21st century, replacing statistics about phone calls with social media and other digital data.

Essentially, Urban Pulse is a dynamic, comparative heat map. And the hot spots on the map are made up of what the research team dubbed “pulses” and “beats,” terminology that was inspired by Park and Burgess’s original analogy.

But Urban Pulse’s findings don’t simply reinforce what we already know about cities. By pinpointing how, when, and by whom city spaces are most often used, the data has the power to upend our preconceptions about civic space. This has potentially far-reaching implications for urban planners, architects, and city planners.

But what is a “pulse?” And where is that social media data coming from? Simply put, a pulse is a graphic representation of the kinds of open source data that serve as proxies for human activity, like tweets and Flickr uploads. Though Urban Pulse currently only uses data from Flickr and Twitter, it is free to download on GitHub, and its creators are hoping to see a wider variety of data types input by the open source community….(More)”.

Gamification, Participatory Democracy and Engaged Public(s)


Paper by Gianluca Sgueo: “The use of game-design elements – a phenomenon known as ‘gamification’ – features prominently within on-going processes of innovation of governance. According to the research and advisory firm Gartner, 2,000 of the top public organizations worldwide have at least one gamified application and/or process in place. Examples of gamification in public governance include “Run that town” (ideated by the Australian Bureau of Statistics to raise citizens’ awareness of the national census), the “Red Balloon Challenge” (initiated by the United States’ Defence Advanced Research Project Agency to test systems for improving cooperation among soldiers, experts and diplomatic officers overseas), and “Manor Labs” (a web platform that awarded “Innobucks”, a type of virtual commodity, to residents of the City of Manor, in Texas, for proposing ideas related with urban development).
The purpose of this paper is threefold: first, to determine who is actually participating in public policy processes via gamification; second, to weigh the impact that the public(s) engaged by gamification has on democratic governance; third, to assess the societal environment within which gamification might flourish or establish plausibly….(More)”.

Polish activists turn to digital democracy


 in the Financial Times: “Opponents of the Polish government have mounted a series of protests on issues ranging from reform of the judiciary to an attempt to ban abortion. In February, they staged yet another, less public but intensely emotive, battle — to save the country’s trees.

At the beginning of the year, a new law allowed property owners to cut trees on their land without official permission. As a result, hundreds of trees disappeared from the centres of Polish cities as more valuable treeless plots were sold off to developers. In parallel, the government authorised extensive logging of the ancient forest in Bialowieza, a Unesco world heritage site.

“People reacted very emotionally to these practices,” says Wojciech Sanko, a co-ordinator at Code for Poland, a programme run by ePanstwo (eState), the country’s biggest non-governmental organisation in this field.

The group aims to deploy new technology tools designed to explain local and national policies, and to make it easier for citizens to take part in public life. As no one controlled the tree-cutting, for example, Mr Sanko thought technology could at least help to monitor it. First, he wanted to set up a simple digital map of trees cut in Warsaw. But as the controversial liberalisation of tree-cutting was reversed, the NGO together with local activists decided to work on another project — to map trees still standing, along with data about species and their absorption of carbon dioxide associated with climate change.

The group has also started to create an app for activists in Bialowieza forest: an open-source map that will gather all documentation from civic patrols monitoring the site, and will indicate the exact places of logging.

A trend towards recruiting technology for civic projects has been slowly gathering pace in a country that is hard to describe as socially-engaged: only 59 per cent of Poles say they have done volunteer work for the community, according to a 2016 survey by the Centre of Public Opinion Research.

Election turnout barely surpasses 50 per cent. Yet since the election of the rightwing Law and Justice government in 2015, which has introduced rapid and controversial reforms across all domains of public life, citizens have started to take a closer look at politicians and their actions.

In addition to the tree map, Code for Poland has developed a website that aggregates public data, such as tax spending or air pollution.

Mr Sanko underlines, however, that Code for Poland is much more about local communities than national politics. Many of the group’s projects are small scale, ranging from a mobile app for an animal shelter in Gdansk and a tool that shows people where they can take their garbage.

Piotr Micula, board member of Miasto Jest Nasze (The City is Ours), an urban movement in Warsaw, says that increasing access to data is fuelling the development of civic tech. “Even as a small organisation, we try to use big data and visualise it,” he says….(More)”.

Advancing Urban Health and Wellbeing Through Collective and Artificial Intelligence: A Systems Approach 3.0


Policy brief by Franz Gatzweiler: “Many problems of urban health and wellbeing, such as pollution, obesity, ageing, mental health, cardiovascular diseases, infectious diseases, inequality and poverty (WHO 2016), are highly complex and beyond the reach of individual problem solving capabilities. Biodiversity loss, climate change, and urban health problems emerge at aggregate scales and are unpredictable. They are the consequence of complex interactions between many individual agents and their environments across urban sectors and scales. Another challenge of complex urban health problems is the knowledge approach we apply to understand and solve them. We are challenged to create a new, innovative knowledge approach to understand and solve the problems of urban health. The positivist approach of separating cause from effect, or observer from observed, is insufficient when human agents are both part of the problemand the solution.

Problems emerging from complexity can only be solved collectively by applying rules which govern complexity. For example, the law of requisite variety (Ashby 1960) tells us that we need as much variety in our problemsolving toolbox as there are different types of problemsto be solved, and we need to address these problems at the respective scale. No individual, hasthe intelligence to solve emergent problems of urban health alone….

  • Complex problems of urban health and wellbeing cause millions of premature deaths annually and are beyond the reach of individual problem-solving capabilities.
  • Collective and artificial intelligence (CI+AI) working together can address the complex challenges of urban health
  • The systems approach (SA) is an adaptive, intelligent and intelligence-creating, “data-metabolic” mechanism for solving such complex challenges
  • Design principles have been identified to successfully create CI and AI. Data metabolic costs are the limiting factor.
  • A call for collaborative action to build an “urban brain” by means of next generation systems approaches is required to save lives in the face of failure to tackle complex urban health challenges….(More)”.

Google Gets Serious About Mapping Wheelchair Accessibility


Linda Poon at CityLab: “If there’s one thing Google’s got at its disposal, it’s a global army of avid map users. Now the company is leveraging that power to make its Maps feature more useful for people with mobility challenges—a group that often gets overlooked in the world of transit and urban innovation.

Google Maps already indicates if a location is wheelchair accessible—a result of a personal project by one of its employees—but its latest campaign will crowdsource data from its 30 million Local Guides worldwide, who contribute tips and photos about neighborhood establishments in exchange for points and small prizes like extra digital storage space. The company is calling on them to answer five simple questions—like whether a building has accessible entrances or bathrooms—when they submit a review for a location. In the coming weeks, Google will host workshops and “geowalks” specifically focused on mobility across seven cities, from New York City and London to Tokyo and Surabaya, Indonesia.

“The [users] have multiple motivations, and one is wanting to help their own community get around.” says Laura Slabin, Google’s director of local content and community. “So we’re leveraging the fact that people are motivated by altruism.”

But as simple as the questions seem—Is there wheelchair-accessible seating? or Is there a wheelchair-accessible elevator?—answering them requires careful attention to detail. That’s why Google even sent out a  nifty tip sheet to help its physically abled members answer those questions….(More)”.

Saving the Soul of the Smart City


Joshua J. Yates at The Hedgehog Review: “…We, too, stand on the cusp of a revolutionary new urban form: “the smart city.” That form emerges from a new wave of intensive urbanization and the proliferating uses of information technology to “optimize” the city’s functioning. It takes shape not uniformly or seamlessly but in fits and starts—in a handful of places all at once, incrementally in others. As was the case with the commuter suburb before it, a potent combination of institutional interests, technological innovations, and cultural appetites fuels the smart city’s rise. But this fact only raises the stakes, demanding that we look as hard at the coming of the smart city as Whyte, Jacobs, and their colleagues looked at the suburban efflorescence….

We can begin taking a hard look at the smart city paradigm by examining its organizing concept: optimization. This term is ubiquitous in discussions about smart cities, and it provides a key to understanding the cultural reasoning behind this new urban form and what that reasoning might be committing us to, morally and civically, over the long run.

By definition, optimization simply means the act of making the most of a process, situation, or resource. It is maximizing potential in light of given circumstances. Facing situations of fiscal austerity, as many of them are, cities are drawn to optimization in their quest to economize. This much is easy to understand. But it is optimization in a more triumphant, maximizing register that underwrites the unquestioning optimism of boosters of the smart city and its potential. For instance, here is how Y Combinator, the Silicon Valley “accelerator” that created Airbnb, recently announced that it was getting into the smart city business: “We want to study building new, better cities. The world is full of people who aren’t realizing their potential in large part because their cities don’t provide the opportunities and living conditions necessary for success. A high leverage way to improve our world is to unleash this massive potential by making better cities….

Narrowing the horizon of living to one overriding register of value, a regime of optimization stamps out the broad, diverse array of conditions that make human life vital. It turns out that some of the things most necessary for human thriving cannot be optimized, and are greatly harmed to the extent that we try. Conviviality, family, friendship, serendipity, play, dependency, trust, calling, and yes, even happiness: These are just a few of the things that make life meaningful and which wither in the soil of optimization. Some of these qualities, as Jane Jacobs reminds us, are able to grow and blossom organically only from the self-organizing everyday forms of human contact that generate spontaneously from vibrant public places and street life. “The ballet of the good city sidewalk,” Jacobs famously wrote, “never repeats itself from place to place, and in any one place is always replete with new improvisations.” Such emergence, as Hannah Arendt reminds us, can come only “against the overwhelming odds of statistical laws and their probability, which for all practical, everyday purposes amounts to certainty; the new therefore always appears in the guise of a miracle.”

Some, Jacobs and Arendt would agree, can come only through the civic friction that physical proximity and cultural particularity generate, and which can lead to genuine dialogue with our neighbors. But some, the philosopher Charles Taylor would remind us, come ultimately through the cultivation of the skills and virtues that power our commitments to working for the good of one another, even possibly at the expense of our own convenience and comforts. If the smart city is to contribute to a thriving human ecology oriented toward truth, justice, and goodness as well as prosperity, beauty, and sustainability, we stand in urgent need of a deep ethical and political turn that will help us cultivate the unoptimizable things for the purposes of making the city not just smart, but wise….(More)”.

MIT map offers real-time, crowd-sourced flood reporting during Hurricane Irma


MIT News: “As Hurricane Irma bears down on the U.S., the MIT Urban Risk Lab has launched a free, open-source platform that will help residents and government officials track flooding in Broward County, Florida. The platform, RiskMap.us, is being piloted to enable both residents and emergency managers to obtain better information on flooding conditions in near-real time.

Residents affected by flooding can add information to the publicly available map via popular social media channels. Using Twitter, Facebook, and Telegram, users submit reports by sending a direct message to the Risk Map chatbot. The chatbot replies to users with a one-time link through which they can upload information including location, flood depth, a photo, and description.

Residents and government officials can view the map to see recent flood reports to understand changing flood conditions across the county. Tomas Holderness, a research scientist in the MIT Department of Architecture, led the design of the system. “This project shows the importance that citizen data has to play in emergencies,” he says. “By connecting residents and emergency managers via social messaging, our map helps keep people informed and improve response times.”…

The Urban Risk Lab also piloted the system in Indonesia — where the project is called PetaBencana.id, or “Map Disaster” — during a large flood event on Feb. 20, 2017.

During the flooding, over 300,000 users visited the public website in 24 hours, and the map was integrated into the Uber application to help drivers avoid flood waters. The project in Indonesia is supported by a grant from USAID and is working in collaboration with the Indonesian Federal Emergency Management Agency, the Pacific Disaster Centre, and the Humanitarian Open Street Map Team.

The Urban Risk Lab team is also working in India on RiskMap.in….(More)”.

The Mobility Space Report: What the Street!?


What the Street!? was derived out of the question “How do new and old mobility concepts change our cities?”. It was raised by Michael Szell and Stephan Bogner during their residency at moovel lab. With support of the lab team they set out to wrangle data of cities around the world to develop and design this unique Mobility Space Report.

What the Street!? was made out of open-source software and resources. Thanks to the OpenStreetMap contributors and many other pieces we put together the puzzle of urban mobility space seen above….

If you take a snapshot of Berlin from space on a typical time of the day, you see 60,000 cars on the streets and 1,200,000 cars parked. Why are so many cars parked? Because cars are used only 36 minutes per day, while 95% of the time they just stand around unused. In Berlin, these 1.2 million parking spots take up the area of 64,000 playgrounds, or the area of 4 Central Parks.

If you look around the world, wasted public space is not particular to Berlin – many cities have the same problem. But why is so much space wasted in the first place? How “fair” is the distribution of space towards other forms of mobility like bikes and trams? Is there an arrogance of space? If so, how could we raise awareness or even improve the situation?

Who “owns” the city?

Let us first look at how much space there is in a city for moving around, and how it is allocated between bikes, rails, and cars. With What the Street!? – The Mobility Space Report, we set out to provide a public tool for exploring this urban mobility space and to answer our questions systematically, interactively, and above all, in a fun way. Inspired by recently developed techniques in data visualization of unrollingpacking, and ordering irregular shapes, we packed and rolled all mobility spaces into rectangular bins to visualize the areas they take up.

How do you visualize the total area taken by parking spaces? – You pack them tightly.
How do you visualize the total area taken by streets and tracks? – You roll them up tightly.…(More)”.
