Determine the severity number for a section of highway that had 2 fatal crash, 48 personal injury crashes, and 105 property damage only crashes during a particular time period. Use a weighting scheme of 50 for fatal crashes, 25 for personal injury crashes, and 1 for crashes with only property damage. Determine the severity index by dividing the severity number by the total number of crashes, thereby normalizing the severity number by the number of crashes.
