There may be a solution to asthma perched high above a handful of Chicago intersections.
Last week, the city began installing sophisticated computers on traffic poles to track air quality, weather and road data at a block-by-block level.
The project's leaders liken the project to giving an entire city its own Fitbit (FIT), which should help it better track and address everything from public health risks to congestion on roads.
"Better data means better outcomes," said Brenna Berman, Chicago's chief information officer.
The city is installing 100 of the computers -- called nodes -- this year. The project's leaders plan to have 500 nodes in place by the end of 2018. The devices cost between $1,200 and $1,600 each, and the research is funded by the National Science Foundation.
