<p>This data set illustrates the daily variation in hard-braking events for a 500-mile section of I-35 in Texas. The 197,000 hard-braking events used in this dataset are extracted from over 48 billion connected vehicle records in Texas in August 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 the connected vehicle. There are 4 files in this dataset:</p>
<p>Aggregated count of hard-braking events per mile per day&nbsp;for I-35 in northbound direction (i35E_NB_HB.csv)<br />
Aggregated count of hard-braking events per mile per day for I-35 in southbound direction (i35E_SB_HB.csv)<br />
