An MIT team uses wireless data from cell phones and GPS devices to track real-time traffic flow (and congestion) in Rome. In 1748, Gianbattista Nolli redefined what modern mapmaking looked like: He offered the first iconographic view of Rome that detailed the dense, urban streets and public spaces, as well as the interiors of buildings. Now more than 250 years later, Carlo Ratti has set out to revolutionize cartography again—this time with the help of cell phones, taxis and buses, and Google maps. Called Real Time Rome, the project paints a new picture of the ancient city: On seven large flexible glass screens and in fiery, fluorescent colors, Ratti and his team are able to show traffic congestion, the routes of the city’s taxis and buses, and where city dwellers are congregating and moving—all with real-time wireless data. “This new type of data provides an understanding of the city that we couldn’t have had a few years ago,” says Ratti, director of MIT’s Senseable City Laboratory, which studies the impact of new technologies on cities. Wireless data, including that from GPS devices located on taxis and buses and aggregated, anonymous cell phone data from Telecom Italia, fuel databases that Ratti’s team uses to create the topographies. The stunning maps have been on display at the Venice Biennale art exhibition since September. During a Madonna concert this past summer, Ratti says he saw some of the “most beautiful patterns” on the screens. “You could see the city pulsating toward where the concert was,” he says, “and how the infrastructure is really being used.” The project has both simple and grand goals. Simple, because Ratti sees benefits for citizens who want to avoid traffic jams and for emergency responders who need to see the most efficient routes. Grand, because “we can change the way we design cities,” Ratti says. “It’s a way to streamline movement in the city.” To that end, Ratti is launching the Senseable City Consortium, an R&D initiative to bring together public administrators, network operators, and hardware and software companies to design smarter urban environments. “Cities, in the past, were built out of concrete,” he says. “Tomorrow, cities will be built out of silicon.” Related content Feature Industry clouds prove their business value Born of partnerships and ecosystem-centric by their nature, cloud solutions aimed at specific verticals are taking root, forming a complex, rapidly evolving market CIOs must be strategic about entering.
