The curled metal fixtures set to go up on a handful of Michigan Avenue light poles later this summer may look like delicate pieces of sculpture, but researchers say they’ll provide a big step forward in the way Chicago understands itself by observing the city’s people and surroundings.

The sensors will also count people by measuring wireless signals on mobile devices.
