Appendix D of this report includes a map showing census tracts with different levels of SVI scores overlaid with the overall HIN. Crash Causation Collision Manner Over 41% of crashes happened between vehicles traveling the same direction, followed by crashes involving only one vehicle, and angle crashes 9 . More than half of the most severe crashes resulted from the action of one motor vehicle Figure 5 and Table 8 .
7, 6 The total and KSI crashes analyzed differ from 68,936 and 2,589, respectively, because some crashes occurred in tracts without an assigned Social Vulnerability Index (SVI).
9 An angle collision occurs when one vehicle strikes another vehicle at an angle somewhere between 90 degrees (referred to as a side- impact collision) and 180 degrees (known as a rear-end collision).
