“Streetfight” by Janette Sadik-Khan

Curated on March 23, 2016August 3, 2018 by Stefaan Verhulst

Review by Amrita Gupta in Policy Innovations of the book Streetfight: “Janette Sadik-Khan was New York City’s transportation commissioner from 2007-2013. Under her watch, the city’s streets were reimagined and redesigned to include more than 60 plazas and 400 miles of bike lanes—radical changes designed to improve traffic and make spaces safer for everybody. Over seven years, New York City underwent a transportation transformation, played out avenue by avenue, block by block. Times Square went from being the city’s worst traffic nightmare to a two-and-a-half acre outdoor sitting area in 2009. Citi Bike, arguably her biggest success, is the nation’s largest bike share system, and the city’s first new transit system in over half a century. In Streetfight, Sadik-Khan breaks down her achievements into replicable ideas for urban planners and traffic engineers everywhere, and she also reminds us that the fight isn’t over. As part of Bloomberg Associates, she now takes the lessons from New York City’s streets to metropolises around the world.

The old order vs the new order

The crux of the problem, she explains, is that until recently, cities of the future were thought to be cities built for cars, not cities that encouraged human activity on the street.

Understanding what city-building used to mean is key to understanding how our cities are failing us today. Sadik-Khan offers a quick recap of New York City through recent decades. The historical lesson holds; in many ways, cities in every continent grew along a similar trajectory. Streets were designed to keep traffic moving, but not to support the life alongside it. The old order—which Sadik-Khan writes is typified by Robert Moses—took the auto-centric view that pedestrians, public transit, and bike riders were all hindrances in the path of cars.

Sadik-Khan calls for a more equitable and relevant city, one that prioritizes accessibility and convenience for everybody. Her generation of planners aims to transform roads, tunnels, and rail tracks—the legacy hardware of their predecessors—and repurpose them into public spaces to walk, bike, and play.

The strength of the book lies in just how effectively it dispels the misconceptions that most citizens, and indeed, urban planners, have held onto for decades. There are plenty of surprises in Streetfight.

Sadik-Khan shows that people’s ideas about safety can be obsolete. For instance, bike lanes don’t make accidents more likely, they make the streets safer. The statistics show that bike riders actually protect pedestrians by altering the behavior of drivers. Sadik-Khan states that bike ridership in New York City quadrupled from 2000-2012; and as the number of riders increases, so too does the safety of the street.

The assumption, for instance, that reducing lanes or closing them entirely creates gridlock, is entirely wrong. Sadik-Khan’s interventions in New York City —providing pedestrian space and creating fewer but more orderly lanes for vehicles—actually improved traffic. And she uses taxi GPS data to prove it….

In fact, Sadik-Khan makes the claim that the economic power of sustainable streets is probably one of the strongest arguments for implementing dramatic change. Cities need data—think retail rents, shop sales, travel speeds, vehicle counts—to defend their interventions, and then to measure their effectiveness. Yet, she writes, unfortunately there are few cities anywhere that have access to reliable numbers of this kind….

Sadik-Khan emphasizes time and again that change can happen quickly and affordably. She didn’t have to bulldoze neighborhoods, or build new bridges and highways to transform the transportation network of New York City. Planners can reorder a street without destroying a single building.

Streetfight is a handbook that prioritizes paint, planters, signs, and signals over mega-infrastructure projects. We are told that small-scale interventions can have transformative large-scale impacts. Sadik-Khan’s pocket parks, plazas, pedestrian-friendly road redesigns, and parking-protected bike lanes are all the proof we need. For planners in developing countries, this should serve as both guide and encouragement.

Innovation doesn’t need big dollars behind it to be effective, and most ideas are scalable for cities big and small. What it does need, however, is street smarts. Sadik-Khan makes it clear that the key to getting projects to move ahead is support on the ground, and enough political capital to pave the way. Planners everywhere need to encourage participation, invite ideas, and be more transparent about proposals, she writes. But they also need to be willing to put up a fight….(More)”

Pigeon patrol takes flight to tackle London’s air pollution crisis

Curated on March 18, 2016August 3, 2018 by Stefaan Verhulst

Adam Vaughan at The Guardian: They’ve been driven from Trafalgar square for being a nuisance, derided as rats with wings and maligned as a risk to public health.

But now pigeons could play a small part in helping Londoners overcome one of the capital’s biggest health problems – its illegal levels of air pollution blamed for thousands of deaths a year.

On Monday, a flock of half a dozen racing pigeons were set loose from a rooftop in Brick Lane by pigeon fancier, Brian Woodhouse, with one strapped with a pollution sensor to its back and one with a GPS tracker.

But while the 25g sensor records the nitrogen dioxide produced by the city’s diesel cars, buses, and trucks and tweets it at anyone who asks for a reading, its real purpose – and the use of the pigeons – is to raise awareness.

“It is a scandal. It is a health and environmental scandal for humans – and pigeons. We’re making the invisible visible,” said Pierre Duquesnoy, who won a London Design Festival award for the idea last year.

“Most of the time when we talk about pollution people think about Beijing or other places, but there are some days in the year when pollution was higher and more toxic in London than Beijing, that’s the reality.”

He said he was inspired by the use of pigeons in the first and second world wars to deliver information and save lives, but they were also a practical way of taking mobile air quality readings and beating London’s congested roads. They fly relatively low, at 100-150ft, and fast, at speeds up to 80mph.

“There’s something about taking what is seen as a flying rat and reversing that into something quite positive,” said Duquesnoy, who is creative director at marketing agency DigitasLBI.

Gary Fuller, an air quality expert at King’s College London, said it was the first time he had heard of urban animals being put to such use.

“It’s great that unemployed pigeons from Trafalgar Square are being put to work. Around 15 years ago tests were done on around 150 stray dogs in Mexico City, showing the ways in which air pollution was affecting lungs and heart health. But this is the first time that I’ve heard of urban wild animals being used to carry sensors to give us a picture of the air pollution over our heads.”

The release of the pigeons for three days this week, dubbed the Pigeon Air Patrol, came as moderate to high pollution affected much of the city, with Battersea recording ‘very high’, the top of the scale.

Elsewhere in the UK, Stockton-on-tees and Middlesbrough recorded high pollution readings and the forecast is for moderate and possibly high pollution in urban areas in northern England and Scotland on Tuesday. Other areas will have low pollution levels….(More).

Crowdsourcing On-street Parking Space Detection

Curated on March 13, 2016August 3, 2018 by Stefaan Verhulst

Paper by Ruizhi Liao et al in: “As the number of vehicles continues to grow, parking spaces are at a premium in city streets. Additionally, due to the lack of knowledge about street parking spaces, heuristic circling the blocks not only costs drivers’ time and fuel, but also increases city congestion. In the wake of recent trend to build convenient, green and energy-efficient smart cities, we rethink common techniques adopted by high-profile smart parking systems, and present a user-engaged (crowdsourcing) and sonar-based prototype to identify urban on-street parking spaces. The prototype includes an ultrasonic sensor, a GPS receiver and associated Arduino micro-controllers. It is mounted on the passenger side of a car to measure the distance from the vehicle to the nearest roadside obstacle. Multiple road tests are conducted around Wheatley, Oxford to gather results and emulate the crowdsourcing approach. By extracting parked vehicles’ features from the collected trace, a supervised learning algorithm is developed to estimate roadside parking occupancy and spot illegal parking vehicles. A quantity estimation model is derived to calculate the required number of sensing units to cover urban streets. The estimation is quantitatively compared to a fixed sensing solution. The results show that the crowdsourcing way would need substantially fewer sensors compared to the fixed sensing system…(More)”

Ideas Help No One on a Shelf. Take Them to the World

Curated on March 2, 2016August 3, 2018 by Stefaan Verhulst

Tina Rosenberg at The New York Times: “Have you thought of a clever product to mitigate climate change? Did you invent an ingenious gadget to light African villages at night? Have you come up with a new kind of school, or new ideas for lowering the rate of urban shootings?

Thanks, but we have lots of those.

Whatever problem possesses you, we already have plenty of ways to solve it. Many have been rigorously tested and have a lot of evidence behind them — and yet they’re sitting on a shelf.

So don’t invent something new. If you want to make a contribution, choose one of those ideas — and spread it.

Spreading an idea can mean two different things. One is to take something that’s working in one place and introduce it somewhere else. If you want to reduce infant mortality in Cleveland, why not try what’s working in Baltimore?

Well, you might not know about what’s working because there’s no quick system for finding it.

Even when a few people do search out the answer, innovative ideas don’t spread by themselves. To become well known, they require effort from their originators. For example, a Bogotá, Colombia, maternity hospital invented Kangaroo Care — a method of keeping premature babies warm by strapping them 24/7 to Mom’s chest. It saved a lot of lives in Bogotá. But what allowed it to save lives around the world was a campaign to spread it to other countries.

The Colombians established Fundación Canguro and got grants from wealthy countries to bring groups of doctors and nurses from all over to visit Bogotá for two or three weeks. Once the visitors had gone back and set up a program in their hospital, the foundation loaned them a doctor and nurse to help get them started. Save the Children now leads a global partnership to spread Kangaroo Care, with the goal of reaching half the world.

In short, this work requires dedicated organizations, a smart program and lots of money.

The other meaning of spreading an idea is creating ways to get new inventions out to people who need them.

“When I talk to college students or anyone who’s thinking about entrepreneurship or targeting global poverty, the gadget is where 99 percent of people start thinking,” said Nicholas Fusso, the director of D-Prize (its slogan: “Distribution is development”). “That’s important — but the biggest problems in the poverty world aren’t a lack of gadgets or new products. It’s figuring out how people can have access to them.” So D-Prize gives seed money, in chunks of $10,000 to $20,000, to tiny new organizations that have good ideas for how to distribute useful things.

This analysis may be familiar to regular readers of Fixes. Indeed, the first Fixes column, more than five years ago, focused on distribution: getting health care to people in rural Africa by putting health care workers on motorcycles and keeping the bikes running….

Philanthropists and government aid agencies are only starting to get interested in the challenges of distribution — one new philanthropy that does have this focus is Good Ventures. As for academia, it still rewards invention almost exclusively. “There’s a lot of attention and award-giving and prize-giving and credit to people who come up with fancy new ideas instead of reaching people and having impact,” said Brodbar. “The incentives aren’t aligned. The culture of social entrepreneurship needs to change.”

Recognizing the true value of spreading an idea would also allow people who aren’t inventors (which is most of us) to get involved in social change. “The notion that if you want to engage in [social entrepreneurship] you have to have the big idea does a disservice to this space and people who want to play a role in it,” said Brodbar. “It’s a much wider front door.”…(More)

The 4 Types of Cities and How to Prepare Them for the Future

Curated on March 1, 2016August 3, 2018 by Stefaan Verhulst

John D. Macomber at Harvard Business Review: “The prospect of urban innovation excites the imagination. But dreaming up what a “smart city” will look like in some gleaming future is, by its nature, a utopian exercise. The messy truth is that cities are not the same, and even the most innovative approach can never achieve universal impact. What’s appealing for intellectuals in Copenhagen or Amsterdam is unlikely to help millions of workers in Jakarta or Lagos. To really make a difference, private entrepreneurs and civic entrepreneurs need to match projects to specific circumstances. An effective starting point is to break cities into four segments across two distinctions: legacy vs. new cities, and developed vs. emerging economies. The opportunities to innovate will differ greatly by segment.

Segment 1: Developed Economy, Legacy City
Examples: London, Detroit, Tokyo, Singapore

Characteristics: Any intervention in a legacy city has to dismantle something that existed before — a road or building, or even a regulatory authority or an entrenched service business. Slow demographic growth in developed economies creates a zero-sum situation (which is part of why the licensed cabs vs Uber/Lyft contest is so heated). Elites live in these cities, so solutions arise that primarily help users spend their excess cash. Yelp, Zillow, and Trip Advisor are examples of innovations in this context.
Implications for city leaders: Leaders should try to establish a setting where entrepreneurs can create solutions that improve quality of life — without added government expense. …

Implications for entrepreneurs: Denizens of developed legacy cities have discretionary income. …

Segment 2: Emerging Economy, Legacy City
Examples: Mumbai, São Paolo, Jakarta

Characteristics: Most physical and institutional structures are already in place in these megacities, but with fast-growing populations and severe congestion, there is an opportunity to create value by improving efficiency and livability, and there is a market of customers with cash to pay for these benefits.

Implications for city leaders: Leaders should loosen restrictions so that private finance can invest in improvements to physical infrastructure, to better use what already exists. …

Implications for entrepreneurs: Focus on public-private partnerships (PPP). …

Segment 3: Emerging Economy, New City
Examples: Phu My Hung, Vietnam; Suzhou, China; Astana, Kazakhstan; Singapore (historically)

Characteristics: These cities tend to have high population growth and high growth rates in GDP per capita, demographic and economic tailwinds that help to boost returns. The urban areas have few existing physical or social structures to dismantle as they grow, hence fewer entrenched obstacles to new offerings. There is also immediate ROI for investments in basic services as population moves in, because they capture new revenues from new users. Finally, in these cities there is an important chance to build it right the first time, notably with respect to the roads, bridges, water, and power that will determine both economic competitiveness and quality of life for decades. The downside? If this chance is missed, new urban agglomerations will be characterized by informal sprawl and new settlements will be hard to reach after the fact with power, roads, and sanitation.
Implications for city leaders: Leaders should first focus on building hard infrastructure that will support services such as schools, hospitals, and parks. …

Implications for entrepreneurs: In these cities, it’s too soon to think about optimizing existing infrastructure or establishing amusing ways for wealthy people to spend their disposable income. …

Segment 4: Developed Economy, New City
Examples and characteristics: Such cities are very rare. All the moment, almost all self-proclaimed “new cities” in the developed world are in fact large, integrated real-estate developments with an urban theme, usually in close proximity to a true municipality. Examples of these initiatives include New Songdo City in South Korea, Masdar City in Abu Dhabi, and Hafen City Hamburg in Germany.

Implications for city leaders: These satellites of existing metropolises compete for jobs and to attract talented participants in the creative economy. ….

Implications for entrepreneurs: Align with city leaders on services that are important to knowledge workers, and help build the cities’ brand. ….

Cities are different. So are solutions….(More)

Cities in the 21st Century

Curated on February 28, 2016August 3, 2018 by Stefaan Verhulst

Book edited by Oriol Nel-lo and Renata Mele: “Cities in the 21^st Century provides an overview of contemporary urban development. Written by more than thirty major academic specialists from different countries, it provides information on and analysis of the global network of cities, changes in urban form, environmental problems, the role of technologies and knowledge, socioeconomic developments, and finally, the challenge of urban governance.

In the mid-20th century, architect and planner Josep Lluís Sert wondered if cities could survive; in the early 21st century, we see that cities have not only survived but have grown as never before. Cities today are engines of production and trade, forges of scientific and technological innovation, and crucibles of social change. Urbanization is a major driver of change in contemporary societies; it is a process that involves acute social inequalities and serious environmental problems, but also offers opportunities to move towards a future of greater prosperity, environmental sustainability, and social justice.

With case studies on thirty cities in five continents and a selection of infographics illustrating these dynamic cities, this edited volume is an essential resource for planners and students of urbanization and urban change….(More)”

Data Collaboratives: Matching Demand with Supply of (Corporate) Data to solve Public Problems

Curated on February 24, 2016August 3, 2018 by Stefaan Verhulst

Blog by Stefaan G. Verhulst, IrynaSusha and Alexander Kostura: “Data Collaboratives refer to a new form of collaboration, beyond the public-private partnership model, in which participants from different sectors (private companies, research institutions, and government agencies) share data to help solve public problems. Several of society’s greatest challenges — from climate change to poverty — require greater access to big (but not always open) data sets, more cross-sector collaboration, and increased capacity for data analysis. Participants at the workshop and breakout session explored the various ways in which data collaborative can help meet these needs.

Matching supply and demand of data emerged as one of the most important and overarching issues facing the big and open data communities. Participants agreed that more experimentation is needed so that new, innovative and more successful models of data sharing can be identified.

How to discover and enable such models? When asked how the international community might foster greater experimentation, participants indicated the need to develop the following:

· A responsible data framework that serves to build trust in sharing data would be based upon existing frameworks but also accommodates emerging technologies and practices. It would also need to be sensitive to public opinion and perception.

· Increased insight into different business models that may facilitate the sharing of data. As experimentation continues, the data community should map emerging practices and models of sharing so that successful cases can be replicated.

· Capacity to tap into the potential value of data. On the demand side,capacity refers to the ability to pose good questions, understand current data limitations, and seek new data sets responsibly. On the supply side, this means seeking shared value in collaboration, thinking creatively about public use of private data, and establishing norms of responsibility around security, privacy, and anonymity.

· Transparent stock of available data supply, including an inventory of what corporate data exist that can match multiple demands and that is shared through established networks and new collaborative institutional structures.

· Mapping emerging practices and models of sharing. Corporate data offers value not only for humanitarian action (which was a particular focus at the conference) but also for a variety of other domains, including science,agriculture, health care, urban development, environment, media and arts,and others. Gaining insight in the practices that emerge across sectors could broaden the spectrum of what is feasible and how.

In general, it was felt that understanding the business models underlying data collaboratives is of utmost importance in order to achieve win-win outcomes for both private and public sector players. Moreover, issues of public perception and trust were raised as important concerns of government organizations participating in data collaboratives….(More)”

Technology and the Future of Cities

Curated on February 24, 2016August 3, 2018 by Stefaan Verhulst

Mark Gorenberg, Craig Mundie, Eric Schmidt and Marjory Blumenthal at PCAST: “Growing urbanization presents the United States with an opportunity to showcase its innovation strength, grow its exports, and help to improve citizens’ lives – all at once. Seizing this triple opportunity will involve a concerted effort to develop and apply new technologies to enhance the way cities work for the people who live there.

A new report released today by the President’s Council of Advisors on Science and Technology (PCAST), Technology and the Future of Cities, lays out why now is a good time to promote technologies for cities: more (and more diverse) people are living in cities; people are increasingly open to different ways of using space, living, working, and traveling across town; physical infrastructures for transportation, energy, and water are aging; and a wide range of innovations are in reach that can yield better infrastructures and help in the design and operation of city services.

There are also new ways to collect and use information to design and operate systems and services. Better use of information can help make the most of limited resources – whether city budgets or citizens’ time – and help make sure that the neediest as well as the affluent benefit from new technology.

Although the vision of technology’s promise applies city-wide, PCAST suggests that a practical way for cities to adopt infrastructural and other innovation is by starting in a discrete area – a district, the dimensions of which depend on the innovation in question. Experiences in districts can help inform decisions elsewhere in a given city – and in other cities. PCAST urges broader sharing of information about, and tools for, innovation in cities.

Such sharing is already happening in isolated pockets focused on either specific kinds of information or recipients of specific kinds of funding. A more comprehensive City Web, achieved through broader interconnection, could inform and impel urban innovation. A systematic approach to developing open-data resources for cities is recommended, too.

PCAST recommends a variety of steps to make the most of the Federal Government’s engagement with cities. To begin, it calls for more – and more effective – coordination among Federal agencies that are key to infrastructural investments in cities. Coordination across agencies, of course, is the key to place-based policy. Building on the White House Smart Cities Initiative, which promotes not only R&D but also deployment of IT-based approaches to help cities solve challenges, PCAST also calls for expanding research and development coordination to include the physical, infrastructural technologies that are so fundamental to city services.

A new era of city design and city life is emerging. If the United States steers Federal investments in cities in ways that foster innovation, the impacts can be substantial. The rest of the world has also seen the potential, with numerous cities showcasing different approaches to innovation. The time to aim for leadership in urban technologies and urban science is now….(More)”
