But in the streets of Singapore, this amounting of "big data" will soon be used to improve urban life through LIVE Singapore! -- a project that uses real-time data to track and affect the activity of a city.
"We can analyze the pulse of the city, moment to moment," says Carlo Ratti, Director of the MIT Senseable city lab, which runs the project as part of the Singapore-MIT alliance for Research and Technology (SMART).
"Over
the past decade, digital technologies have begun to blanket our cities,
forming the backbone of a large, intelligent infrastructure," says
Ratti, who believes cities have become open-air computers storing
information that should be harnessed and tapped into.
The team are exploring the use of data in Singapore due to its unique existence as a city, nation and island.
"It becomes an ideal lab to study the link between technology and city planning," says Ratti.

Traffic, crowds and rainfall
By
tapping in to real-time information about their city, Singaporeans
could make day-to-day decisions based on their environment -- creating a
feedback loop between people, their actions and their city -- whilst
simultaneously contributing to the data they are collecting.
Such
feedback can impact factors influencing daily life, ranging from
overcrowding and traffic jams to temperature control and taxi
availability. The more data available, the more impact it can have.
"The power increases exponentially," says Ratti.
One example is the monitoring of mobile
phone use throughout the city-state to track the movements of people and
provide information about crowding.
According
to the MIT Senseable city lab, mobile phone penetration in Singapore is
more than 140%, as people own more than one mobile phone.
By
using data from cell phone networks in Singapore, maps can be created
to visualize where usage is highest -- and therefore where the number of
people is highest.
The use of urban space can be revealed in real-time.
A
more environmental example is the tracking of people and vehicles
during rainfall. Singapore's tropical climate means rainfall is frequent
and torrential.
"The local weather has
a major impact on the behaviour of a population," says Gerhart Schmitt,
Professor of Information Architecture and Founding Director of the Singapore-ETH Centre in Singapore. "[It is] at the same time influenced by and influencing the population," he says.
Schmitt's
center are developing a range of visualization technologies to inform
users about factors such as air quality -- when planning a route to walk
-- or traffic jam prediction.
Tailored Taxis
According
to Schmitt, taxis make up almost 1/5 of the car transportation load in
Singapore and numbers are expected to be similar in other high-density
cities worldwide.
"It's important...to visualize the availability of taxis," says Schmitt.
For LIVE Singapore, Ratti's team have
combined this demand for taxis with the city's climate. Their sample
visualization blends taxi locations and rainfall data to enable the
development of apps helping locals hail taxis during a downpour.
The
use of this form of data is somewhat limitless with potential and has
also been used to visualize temperature hotspots based on the 'heat
island' effect where buildings, cars and the use of cooling units causes
temperatures to rise, as well as broader scale information such as the
global reach of Singapore's ports and airports.
Schmitt's
teams are exploring the uses of public transport data generated from
smart-card based ticketing systems now common across the world and
further researching the urban heat island effects in Singapore, which
they believe will eventually reduce liveability. "[It] has become quite
serious," he says
Is there an app for that?
For
now, Ratti is mainly showing the potential uses of big data generated
within a city like Singapore but his goal is to make the data more
readily available, and accessible, to create a platform on which others
access the data and create new apps tailored to the city's needs.
"The
way it will change people's lives is through different types of apps,"
says Ratti. "LIVE Singapore! can start ideas for combining data, which
can become apps," he says.
This is the goal of Ratti's follow-up data project -- data collider -- due to launch publicly in 6 months as a broader platform to spark new ideas.
"Anybody can use it to visualize and explore the data and learn more about their city," he says.
