<p>This data set illustrates the daily variation in hard-braking events for five interstate routes (I-65, I-69, I-70, I-94 and I-465) in Indiana. 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>
