Chicago becomes first city to launch Array of Things, an innovative urban sensing project
“The Array of Things project is just one example of the advancements that are possible when the city, university and Argonne combine their diverse and complementary perspectives, experience and expertise,” said Argonne Director Peter B. Littlewood. “I’m excited to see the Array of Things fulfill its potential to help make Chicago cleaner, healthier and more livable, and I also look forward to future game-changing collaborations with our local partners.”
ANL notes that initial node locations and data applications were determined based on interactions with community organizations and research groups. Eight nodes in Pilsen will contain sensors for tracking air quality and its relationship with asthma and other diseases. Partnerships with the Chicago Loop Alliance and Vision Zero motivated studies of pedestrian and vehicle flow and traffic safety in The Loop neighborhood. And scientists at UChicago and Argonne chose locations along the lake and across the middle of Chicago that will allow for optimal measurements of features related to urban weather and climate change.
“The Array of Things is a community technology,” said Charlie Catlett, director of the Urban Center and Computation and Data at the University of Chicago and Argonne and the lead investigator of Array of Things. “It’s about creating new streams of data that help us understand and address the most critical urban challenges. Where we see an intersection of resident concerns, science interests and policymaker interest, that’s where we see opportunity for Array of Things deployment in Chicago.”
Array of Things will also support City of Chicago efforts to provide smarter and proactive services using predictive analytics and data-driven policy. For example, by tracking the weather conditions leading up to flooding at intersections, city crews can respond more quickly to floods or make infrastructural changes that prevent standing water from accumulating. City departments could also use data on heavy truck traffic and air quality to make decisions about commercial routing that preserves clean air and safe roads in residential neighborhoods.
“It’s truly doing science in the city and out in the communities. We’ll be able to engage with community groups to help them make the data their own and figure out to use it to address the questions they have,” said Brenna Berman, Chief Information Officer of the City of Chicago. “You’re going to see community groups use this data to understand their communities and neighborhoods better as we all try to build a better life here in Chicago.”
Data collected by Array of Things nodes will be open, free, and available to the public, researchers and developers. After a brief period of testing and calibration, the project will publish data through the City of Chicago Data Portal, open data platform Plenar.io, and via application programming interfaces. As specified by the Array of Things privacy and governance policies, no personally identifiable information will be stored or released by sensor nodes.
Array of Things is funded by a $3.1 million grant from the National Science Foundation, with additional investments from Argonne and the Chicago Innovation Exchange.
“We at the National Science Foundation are proud to support the Array of Things,” said Jim Kurose, head of Computer and Information Science and Engineering at NSF. “The launch of the first nodes will provide important information and data-driven insights about the health of cities and residents, and illustrate how fundamental research is vital to the transformation of our local communities envisioned by the National Smart Cities Initiative.”
