"Smart" benches are spreading—recently a series of them, manufactured by Soofa, was installed in a tiny neighborhood park next to I-77 on the north end of Charlotte, North Carolina with the intent of the neighborhood's analysis and redevelopment.

Soofa, founded in 2014 by three graduates of MIT Media Lab, is one of a handful of companies designing data-collecting street furniture.

While the sensors can't access personal information from your phone, they pick up and remember your devices' MAC address. The technology allows cities and urban planners to count users of various public spaces, identifying when and for how long they're visited, and potentially optimizing their design.
