The largest dataset the city of Chicago has ever released through its online open data portal went live Tuesday, offering up a vast amount of information about the city’s Divvy bike-sharing program. Included in the dataset is bicycle and docking spot availability at city bike-sharing stations, recorded in 10 minute intervals, from 2013 up until the present. Also released was every record for Divvy trips in the past two years, according to the city’s chief data officer, Tom Schenk Jr. Tuesday’s release is the first time bike-sharing data has been published on Chicago’s open data portal, a website that acts as a clearinghouse where city datasets are made publicly available.
