The life of the city is often described as a “fast book”. A new study shows that this is more true.
Co-writer by MIT scholars, research suggests that the average running speed of pedestrians in three Northeast American cities increased by 15 percent from 1980 to 2010. The number of people living in public places declined by 14 percent at that time.
Researchers used machine-learning tools to assess video footage of the 1980s occupied by the famous urban William White in Boston, New York and Philadelphia. He compared the old content with new videos from equal places.
“Something has changed in the last 40 years,” says the professor of the practice of Carlo Ratti, co-writer of new studies. “How fast we move, how do people meet in public place – what we are seeing here is that public places are working in some different ways, more a well and low encounter location.”
Paper, “The discovery of social life of urban places through AI,” is published in this week Action of National Science AcademyCo-writer Ariana Salazar-Miranda MCP ’16, PhD ‘is an assistant professor in the School of the Environment of Yale University; Hong Kong University’s Zhuangan fan; Michael back; Keith n. Hampton, a professor at Michigan State University; Fabio Duterte, Associate Director of Sensational City Lab; Becky Pay Lu of Hong Kong University; Edward Glasar, Fred and Ellenor Glimp Professor of Economics at Harvard University; And Ratti, who is also the director of the Sensitive City Lab of MIT.
The results can help notify urban planning, as designers try to create new public sector or revise existing people.
“Public place is an important element of civil life, and today partially because it retaliates the polarization of digital space, called Salazar-Miranda. “The more we can improve public space, the more we can make our cities favorable for combination.”

White was a prominent social thinker, whose famous 1956 book, “The Organization Man”, became a touchstone of its decade, investigating the clear culture of corporate conformity in the US.
However, White focused the decades after his career on urbanism. The footage he filmed from 1978 to 1980 was stored by the Brooklyn-based non-profit non-profit organization, called the Project for Public Space and was later digitized by Hepton and his students.
White chose his recording at four places in all three cities: Boston’s downtown crossing area; Bryant Park in New York City; Metropolitan Museum of Art’s steps in New York, a famous gathering point and people viewing places; And Philadelphia’s Chestnut Street.
In 2010, a group led by Hampton shot new footage at those places, near White at the same time of the day, comparing and vice versa to compare the present day dynamics over the time of white. To conduct the study, co-writers used computer vision and AI models to brief and determine the activity in the video.
Researchers have found that some things have not changed much. The percentage of people running alone was barely gone, from 67 percent to 68 percent in 2010 in 1980. On the other hand, the percentage of individuals entering these public places which became part of a group decreased slightly. In 1980, 5.5 percent of the people arriving at these places met with a group; In 2010, it was below 2 percent.
“Perhaps today there is a more transaction for a public place,” says Ratti.
Low exterior group: anomi or Starbucks?
If people’s behavior patterns have changed since 1980, then it is natural to ask why. Certainly some visual changes seem to suit the broad use of cellphones; People now organize their social life by phone, and perhaps zip around faster than the resulting place.
“When you look at William White footage, people from public places were looking at each other more,” Ratti says. “This was a place you can start or run as a friend. You could not do online things then. Today, behavior is more dedicated to texting, to meet in public place.”
As scholars have noted, if groups of people move together slightly less together in public places, there may still be another reason for this: Starbucks and its competitors. As stated in the paper, “The dissemination of coffee shops and other indoor locations may be less common for outdoor groups. Instead of dull on the footpaths, people may have tolerate their social interactions to air conditioned, more comfortable private places.”
Certainly in 1980, coffeeshops were very rare in large cities, and large chain coffeesops were not present.
On the other hand, public-intercost behavior at this time, can develop starbucks and regardless regardless of such. Researchers say that the new study provides a proof-off-concept for its method and has encouraged them to do extra work. Other researchers at Ratti, Dute, and other researchers of MIT’s sensory City Lab have attracted their attention to a comprehensive survey of European public places in an attempt to throw more light on the interaction between people and public forms.
“We are collecting footage from 40 squares in Europe,” says Duterte. “The question is: How can we learn on a large scale? It is in the part we are doing.”
