Now, ‘cell phone map’ of cities!
NEW
DELHI, Oct. 11. — Enforcement authorities for long have been able to
track movements of people with the help of the cell phone used by them,
but now researchers at the Massachussets Institute of Technology have
electronically mapped a whole city with the help of just the cell phone
usage data, which in future could help authorities in responding to
issues like traffic congestion and disasters in a city.
Using anonymous cell phone data, the researchers at the premier US
institute created electronic maps of Graz, the second-largest city in
Austria.
“The real-time city is now real: a system that is able to continuously
sense its condition and can quickly react to its criticalities” says Mr
Carlo Ratti, architect and engineer and head of the project at the
SENSEable City Laboratory, MIT.
A cell phone network operating in the city of Graz sent anonymous
information about the density of cell phone calls made and the origin
and destination of calls.
Combined with this, the team used the data of voluntary participants
who agreed to get their mobiles “pinged” by the team, to map a whole
city in all its vibrancy.

traffic planners a new way to track congested areas in Graz. — PTI
