The Array of Things (AoT) is an urban sensing project, a network of interactive, modular sensor boxes that will be installed around Chicago to collect real-time data on the city's environment, infrastructure, and activity for research and public use. AoT will essentially serve as a "fitness tracker" for the city, measuring factors that impact livability in Chicago such as climate, air quality and noise. Array of Things is an urban-scale "instrument" that will enable the City, urban planners, residents, and researchers to monitor and examine Chicago's environment, infrastructure and activity, including detecting trends and changes over time. Ultimately, the goal is to measure the city in sufficient detail to provide data to help engineers, scientists, policymakers and residents work together to make Chicago and other cities healthier, more livable and more efficient. AoT will provide real-time, location-based data about the city's environment, infrastructure and activity to researchers and the public. This initiative has the potential to allow researchers, policymakers, developers and residents to work together and take specific actions that will make Chicago and other cities healthier, more efficient and more livable. The data will help make Chicago a truly "smart city," allowing the City to operate more efficiency and realize cost savings by anticipating and proactively addressing potential problems like urban flooding.
