Appendix A—Detail on Calculations of the Ontario Model<br />
Exhibit A-4<br />
Allocation of Additional Injuries among Collision Severity Categories<br />
for 2004<br />
Collision Severity<br />
Fatal Injury PDO TOTAL<br />
Vehicles damaged:<br />
Demolished # 711 10,635 6,634 17,980<br />
Demolished % 4% 59% 37% 100%<br />
Allocated Additional Injuries:<br />
Major 68 1,022 637 1,728<br />
Minor 1,219 18,222 11,366 30,807<br />
Minimal 763 11,413 7,119 19,295<br />
Exhibit A-5 presents the initial allocation of additional injuries and fatalities<br />
among collision severity categories. Note that the allocation methods identify fatalities<br />
among injury collisions and injuries among PDOs. Next we move collisions between<br />
severity categories to restore the original definitions within the model.<br />
