Last week, Chicago debuted the first two of 500 “fitness trackers for the city” — modular sensor boxes mounted on light poles that will collect data on air quality, weather, noise levels, vehicular and pedestrian traffic and other vitals. According to USA Today, the data they collect will go live and public by October. By the end of the year, 50 of the beehive-shaped nodes will be installed. Once all 500 planned nodes are live by 2018, they will provide the city and public with access to block-by-block data that could inform everything from Vision Zero planning to routes to school for asthmatic children.
