It's called “the nursery.” A half-dozen white-domed machines lie on racks in a high-ceilinged room at Argonne National Laboratory, about half an hour west of the city. With the low, winter afternoon sun hitting them just right, it’s not a stretch to imagine them as eggs warming in an incubator.
These little plastic nodes are packed with sensors and backed by millions in federal funding. Eventually, the microwave-sized devices will make their way out to lampposts in Chicago or Detroit or Denver or beyond to quietly measure the world around them. They’ll look for traffic patterns, and they’ll measure sound. They’ll count particles in the air and note the amount of carbon monoxide, sulfur dioxide, and other pollutants present. They’ll measure vibration, magnetic fields, and light. And if all goes according to plan, they’ll send this information back to a database where scientists, city officials, hacktivists, and residents will be able to access and analyze the streams of hyperlocal data.
This is the vision of the Array of Things (AoT), a joint initiative between Argonne, a U.S. Department of Energy laboratory operated by a subsidiary of the University of Chicago, the University of Chicago, the City of Chicago, and various technology firms. The project expects to start publishing data from its preliminary nodes to the city’s open-data portal earlier this year, at which point they hope to have a hundred of them up around the city quietly quantifying the traffic, noise, and emissions that make city living unpleasant at least, and environmentally unjust at worst.
ATLANTA — As cities have begun to collect and release unprecedented amounts of data, questions about citizen privacy have become increasingly relevant. Local governments, for their part, often lack specific privacy policies and rely on checks such as community outcry, industry best practices and guidance from law professors to dictate the limits of their work. This was an overarching topic at many panels during the recent MetroLab Annual Summit.
Perception is also important, as Chicago and its collaborators learned upon launching the Array of Things project, an influential smart cities initiative made up of thousands of nodes. Array of Things, which is in the process of being spread to other cities, was born of a collaboration between the city and researchers at the University of Chicago, like Charlie Catlett, the director of the Urban Center for Computation and Data.
Catlett said that when they were first setting up the nodes that collect data for the Array of Things project, the community was skeptical of any government effort to collect info, so technologists had to learn to become very deliberate when they explained what they were doing and why.
