Nearly 700,000 hard-braking events used in this dataset were extracted from over 600 million hard-braking events that occurred in Indiana between May and October 2020. A hard-braking event is defined as a deceleration of more than 8.76 ft/s<sup>s</sup> (2.67m/s<sup>2</sup>), as measured by an accelerometer on-board a connected vehicle. The dataset (hb_IN_interstates.csv) consists of following attributes:</p> <ol> <li>route - Route name with direction. For example, I-65 N refers to interstate I-65 in northbound direction. I-465 IL and I-465 OL refers to Inner Loop and Outer Loop on I-465, respectively.</li> <li>date - Date on which the event took place</li> <li>mile_marker - Nearest mile-marker where the event took place</li> <li>hb_count - Number of of hard-braking events</li> </ol> <p>Supporting documents include a presentation and video highlighting the daily variation in hard-braking events across these interstates.</p>
