The wisdom of crowds: The strange but extremely valuable science of how pedestrians behave

From The Economist

Imagine that you are French. You are walking along a busy pavement in Paris and another pedestrian is approaching from the opposite direction. A collision will occur unless you each move out of the other’s way. Which way do you step?

The answer is almost certainly to the right. Replay the same scene in many parts of Asia, however, and you would probably move to the left. It is not obvious why. There is no instruction to head in a specific direction (South Korea, where there is a campaign to get people to walk on the right, is an exception). There is no simple correlation with the side of the road on which people drive: Londoners funnel to the right on pavements, for example.

Instead, says Mehdi Moussaid of the Max Planck Institute in Berlin, this is a behaviour brought about by probabilities. If two opposing people guess each other’s intentions correctly, each moving to one side and allowing the other past, then they are likely to choose to move the same way the next time they need to avoid a collision. The probability of a successful manoeuvre increases as more and more people adopt a bias in one direction, until the tendency sticks. Whether it’s right or left does not matter; what does is that it is the unspoken will of the majority. More…

In One Slum, Misery, Work, Politics and Hope

From Jim Yardley at The New York Times

At the edge of India’s greatest slum, Shaikh Mobin’s decrepit shanty is cleaved like a wedding cake, four layers high and sliced down the middle. The missing half has been demolished. What remains appears ready for demolition, too, with temporary walls and a rickety corrugated roof.

Yet inside, carpenters are assembling furniture on the ground floor. One floor up, men are busily cutting and stitching blue jeans. Upstairs from them, workers are crouched over sewing machines, making blouses. And at the top, still more workers are fashioning men’s suits and wedding apparel. One crumbling shanty. Four businesses.

In the labyrinthine slum known as Dharavi are 60,000 structures, many of them shanties, and as many as one million people living and working on a triangle of land barely two-thirds the size of Central Park in Manhattan. Dharavi is one of the world’s most infamous slums, a cliché of Indian misery. It is also a churning hive of workshops with an annual economic output estimated to be $600 million to more than $1 billion. More…

The Case Against Economic Disaster Porn

From Noreen Malone at The New Republic

When I sat down to my keyboard recently to Google the city of Detroit, the fourth hit was a site titled “the fabulous ruins of Detroit.” The site—itself a bit of a relic, with a design seemingly untouched since the 1990s—showed up in the results above the airport, above the Red Wings or the Pistons, the newspapers, or any other sort of civic utility. Certainly above anything related to the car industry, for which the word Detroit was once practically a synonym. Pictures of ruins are now the city’s most eagerly received manufactured good.

We have begun to think of Detroit as a still-life. This became clear to me recently, when the latest set of “stunning” pictures of Detroit in ruins made the rounds, taken by Yves Marchand and Romain Meffre for a book, The Ruins of Detroit. They were much tweeted and blogged about (including by TNR’s own Jonathan Chait), as other such “ruin porn” photosets of blighted places have been, and were described variously as wonderful, as beautiful, as stunning, as shocking, as sad. They are all of those things, and so I suppose they are good art. But they are rotten photojournalism. More…

Arthur C Clarke Predicting the Future in 1964

The City as The Ultimate Bubble

From Misha Lepetic, 3 Quarks Daily

Purpose-built cities are nothing new, especially when an authoritarian government seeks to establish a new capital far from the distractions and chaos of the commercial capital. Recent and well-known examples include Abuja, Naypyidaw and Brasilia, but one can go further back into history to find others: St Petersburg and Washington, D.C. are principal examples from the 18th century, and Ayutthaya was established in 1350 by King U Thong and remained the capital of the Kingdom of Siam until it was razed by the Burmese Army in 1767. Nature has been equally adept at forcing the hand of governments, however: Belmopan, the current capital of Belize, was built following 1961’s Hurricane Hattie, which nearly leveled Belize City (then the capital of British Honduras, if we are to be perfectly accurate in these matters).

Unilaterally decreeing the establishment of a city is not without its risks, of course. The urban form acquires its robustness through a complex, dynamic and unpredictable confluence of people engaging in economic, military and cultural activity. Another crucial ingredient is any city’s contextual relationship to the rest of the world, usually represented by access to either resources or control of valuable trade routes. Thus it is not surprising to learn of the fate of Akhetaten, hardly outlived by its founder, the Pharaoh Akhenaten, father of Tutankhamen. Now known as Amarna, it was founded by Akhenaten’s vision of a society unified through the worship of a single cult, that of the Sun or the Aten. However, 1353 BC proved to be a bit early for the monotheistic worldview, and following Akhenaten’s death both the city and his theological innovation were abandoned within a few years.

Detroit: City of stunning contradictions

photo by Andrew Moore, from the article

From Emma Mustich in Salon.com:

Even if you’ve never visited Detroit, the city’s name might call up an image in your head — perhaps one of the chilling, almost apocalyptic photographs of urban decay that are frequently passed around the Internet.

But that’s hardly the whole picture, as Nancy Barr, curator of “Detroit Revealed: Photographs, 2000-2010″ (which opens next month at the Detroit Institute of Arts), told me this week. In Barr’s eyes — and the eyes of the photographers whose work her show features — Detroit is a city of contradictions, populated by autoworkers and immigrants, optimistic high schoolers and up-all-night-DJs, urban adventurers and sheep.

The 2012 Spaces and Flows Conference will take place in Detroit.

At Vacant Homes, Foraging for Fruit

From Kim Severson at The New York Times

As she does every evening, Kelly Callahan walked her dogs through her East Atlanta neighborhood. As in many communities in a city with the 16th-highest foreclosure rate in the nation, there were plenty of empty, bank-owned properties for sale.

She noticed something else. Those forlorn yards were peppered with overgrown gardens and big fruit trees, all bulging with the kind of bounty that comes from the high heat and afternoon thunderstorms that have defined Atlanta’s summer.

So she began picking. First, there was a load of figs, which she intends to make into jam for a cafe that feeds homeless people. Then, for herself, she got five pounds of tomatoes, two kinds of squash and — the real prize — a Sugar Baby watermelon.

“I don’t think of it as stealing,” she said. “These things were planted by a person who was going to harvest them. That person no longer has the ability to. It’s not like the bank people who sit in their offices are going to come out here and pick figs.” More…

Open Source Urbanism

An op-ed from Saskia Sassen at Domus, image taken from The Pop-Up City

The author proposes that urbanizing technology can can allow people to better “talk back” to cities and implement user-driven change

Where change is perceptible, rapid change makes change itself even more visible. Velocity becomes a concrete condition, not just a measure of speed. Rapid change in cities has highly legible moments—the material reality of buildings, transport systems, re-placements of modest shops with luxury shops and of modes middle-classes with the rich professional class, a bike-path where there was none—and they can be both good and not so good. Further, when rapid transformation happens simultaneously in several cities with at least some comparable conditions, it also makes visible how diverse the spatial outcomes can be even when the underlying dynamics might be quite similar.

All of this brings to the fore the differing degrees of openness of cities. I prefer thinking of this as the incompleteness of cities, which means that they can constantly be remade, for better or for worse. It is this incompleteness that has allowed some of the world’s great old cities to outlast kingdoms, empires, nation-states and powerful firms. More…

Detroit Pushes Back With Young Muscles

From Jennifer Conlin,

The rooftop party was in full swing when midnight approached on a warm Friday evening. Kerry Doman, 29, founder of an event planning business; Justin Jacobs, 28, head of a citywide recreational sports league, and Ara Howrani, 29, a photographer who runs a commercial studio, knocked back beers, while a group of office friends from a nearby dot-com chatted about the scratch-and-sniff wallpaper in their colorful new headquarters.

In another circle, a group of real estate brokers excitedly discussed the renovation of a 1920s office tower called the Broderick into a 127-unit apartment building with a restaurant, lounge and retail stores.

“I want the penthouse,” Jeffrey Hillman, 37, said jokingly as he pointed to the building’s ornate Baroque-style top in the distance. “I’ll fight you for it,” retorted Hank Winchester, 37, a local TV reporter.

The scene might have been run of the mill in Seattle or Williamsburg, Brooklyn, or other urban enclaves that draw the young, the entrepreneurial and the hip. But this was downtown Detroit, far better known in recent years for crime, blight and economic decline.

Recent census figures show that Detroit’s overall population shrank by 25 percent in the last 10 years. But another figure tells a different and more intriguing story: During the same time period, downtown Detroit experienced a 59 percent increase in the number of college-educated residents under the age of 35, nearly 30 percent more than two-thirds of the nation’s 51 largest cities.

Europe Stifles Drivers in Favor of Alternatives

From Elizabeth Rosenthal in the New York Times:

While American cities are synchronizing green lights to improve traffic flow and offering apps to help drivers find parking, many European cities are doing the opposite: creating environments openly hostile to cars. The methods vary, but the mission is clear — to make car use expensive and just plain miserable enough to tilt drivers toward more environmentally friendly modes of transportation. More…
