Mayor Rahm Emanuel and the Department of Innovation and Technology announced Chicago won a Smart 50 Award from Smart Cities Connect for its innovative Array of Things program, the first of its kind to be implemented on a city-wide scale.  Smart 50 Awards honor the 50 most innovative and influential smart cities projects each year from around the globe. Array of Things (AoT) is a network of interactive, modular sensor boxes that measure real-time data on the city’s environment, infrastructure and activity for research and public use. The goal is to make city services more efficient and effective for Chicagoans by anticipating and proactively addressing challenges such as urban flooding and traffic safety. AoT will serves as a “fitness tracker” for the city, measuring factors that impact livability in Chicago such as climate, air quality and noise to help detect heavy vehicle traffic, identify standing water in real time to prevent property damage and illness and observe which areas of the city are heavily populated by pedestrians at different times of day to suggest safe and efficient routes for walking to improve pedestrian safety. The Array of Things program is managed by University of Chicago and Argonne National Laboratory, along with the City, and funded by a National Science Foundation grant.
