We use the characteristics of fatal collisions 1 to move an appropriate number of<br />
collisions with the same characteristics from the injury collision severity group to the<br />
fatal severity group. This is illustrated in the hypothetical example provided below.<br />
In this example, the average fatal collision has the following characteristics–1<br />
fatality, 3 injuries and 10 vehicles involved. There are 3 fatalities assigned to injury<br />
collisions after the adjustments noted earlier. Assuming the collisions, involving the 3<br />
fatalities, but listed as injury collisions are like other fatal collisions, allows us to identify<br />
3 collisions, with 3 fatalities, 9 injuries and 30 vehicles involved among injury collisions.<br />
Transferring these collisions from injury to fatal collisions would increase fatal collisions<br />
1 Each fatal collision includes 1.11 fatality, 0.44 major injury, 2.16 minor injury, 1.33 minimal injury and<br />
involves the following vehicles by damage level: 0.99 demolished, 0.27 severe, 0.21 moderate, 0.18 light<br />
and 0.07 none.<br />
