City of Chicago, Illinois


Chicago wanted to build a technology platform to collect information about livability issues that could be applied to urban planning and design.


Through a National Science Foundation research grant, awarded to the University of Chicago and Argonne National Laboratory, launched a pilot program last year to build a platform called the Array of Things (AoT), a sort of “Fitbit” to track climate, air quality, and noise on a block-by-block basis.

Small boxes are mounted on streetlights, look like beehives, and have multiple sensors that can collect highly accurate micro-data on temperature, barometric pressure, light, and pollution. They can also capture vibration, sound intensity, and images that allow the users to see things like cloud cover, or the number of pedestrians on a sidewalk, bicycles on a street, or vehicles in an intersection.

The technology can be used for such purposes as providing citizens information useful in their daily lives, to address larger community concerns, or for academic research. As examples, a researcher may be interested in understanding walkability in a neighborhood; air-quality sensors can help residents with asthma by providing alerts; or the city may leverage data to automatically deploy services to deal with standing water instead of waiting for it to be reported.

An initial 40 locations have been decided, nodes are being installed, and the city has begun identifying the next 60 deployments.
