Life in the City Is Essentially One Giant Math Problem


Smithsonian Magazine : “A new science—so new it doesn’t have its own journal, or even an agreed-upon name—is exploring these laws. We will call it “quantitative urbanism.” It’s an effort to reduce to mathematical formulas the chaotic, exuberant, extravagant nature of one of humanity’s oldest and most important inventions, the city.
The systematic study of cities dates back at least to the Greek historian Herodotus. In the early 20th century, scientific disciplines emerged around specific aspects of urban development: zoning theory, public health and sanitation, transit and traffic engineering. By the 1960s, the urban-planning writers Jane Jacobs and William H. Whyte used New York as their laboratory to study the street life of neighborhoods, the walking patterns of Midtown pedestrians, the way people gathered and sat in open spaces. But their judgments were generally aesthetic and intuitive…
Only in the past decade has the ability to collect and analyze information about the movement of people begun to catch up to the size and complexity of the modern metropolis itself…
Deep mathematical principles underlie even such seemingly random and historically contingent facts as the distribution of the sizes of cities within a country. There is, typically, one largest city, whose population is twice that of the second-largest, and three times the third-largest, and increasing numbers of smaller cities whose sizes also fall into a predictable pattern. This principle is known as Zipf’s law, which applies across a wide range of phenomena…”

Guide to Social Innovation


Social InnovationForeword of European Commission Guide on Social Innovation: “Social innovation is in the mouths of many today, at policy level and on the ground. It is not new as such: people have always tried to find new solutions for pressing social needs. But a number of factors have spurred its development recently.
There is, of course, a link with the current crisis and the severe employment and social consequences it has for many of Europe’s citizens. On top of that, the ageing of Europe’s population, fierce global competition and climate change became burning societal challenges. The sustainability and adequacy of Europe’s health and social security systems as well as social policies in general is at stake. This means we need to have a fresh look at social, health and employment policies, but also at education, training and skills development, business support, industrial policy, urban development, etc., to ensure socially and environmentally sustainable growth, jobs and quality of life in Europe.”

Two-Way Citizen Engagement


StuffGovernment Technology: “A couple of years ago, a conversation was brewing among city leaders in the Sacramento, Calif., suburb of Elk Grove — the city realized it could no longer afford to limit interactions with an increasingly smartphone-equipped population to between the hours of 8 a.m. and 5 p.m… The city considered several options, including a vendor-built mobile app tailor-made to meet its specific needs. And during this process, the city discovered civic engagement startup PublicStuff. Founded by Forbes’ 30 Under 30 honoree Lily Liu, the company offers a service request platform that lets users report issues of concern to the city.

Liu, who previously held positions with both New York City and Long Beach, Calif., realized that many cities couldn’t afford a full-blown 311 call center system to handle citizen requests. Many need a less expensive way of providing responsive customer service to the community. PublicStuff now fills that need for more than 200 cities across the country.”

Data-Driven Public Transport Planning


CaptureDavid Talbot in MIT Technology Review: “Researchers at IBM, using movement data collected from millions of cell-phone users in Ivory Coast in West Africa, have developed a new model for optimizing an urban transportation system….
While the results were preliminary, they point to the new ways that urban planners can use cell-phone data to design infrastructure, says Francesco Calabrese, a researcher at IBM’s research lab in Dublin, and a coauthor of a paper on the work. “This represents a new front with a potentially large impact on improving urban transportation systems,” he says. “People with cell phones can serve as sensors and be the building blocks of development efforts.”
The IBM work was done as part of a research challenge dubbed Data for Development, in which the telecom giant Orange released 2.5 billion call records from five million cell-phone users in Ivory Coast. The records were gathered between December 2011 and April 2012. The data release is the largest of its kind ever done. The records were cleaned to prevent anyone identifying the users, but they still include useful information about these users’ movements. The IBM paper is one of scores being aired later this week at a conference at MIT.”
