Ontario Model Step 3 Allocate additional injuries based on proportion of demolished vehicles Collision Severity Fatal Injury PDO Injuries: Major 50 100 Minor 70 150 Minimal 60 125 Additional injuries: Major 100 Minor 200 Minimal 50 Vehicles damaged: Demolished 10 50 40 Injuries: Major 50 + 10 100 + 50 0 + 40 Minor 70 + 20 150 + 100 0 + 80 Minimal 60 + 5 125 + 25 0 + 20 Injuries: Major 60 150 40 Minor 90 250 80 Minimal 65 150 20 We use the characteristics of fatal collisions 1 to move an appropriate number of collisions with the same characteristics from the injury collision severity group to the fatal severity group. This is illustrated in the hypothetical example provided below. In this example, the average fatal collision has the following characteristics–1 fatality, 3 injuries and 10 vehicles involved. There are 3 fatalities assigned to injury collisions after the adjustments noted earlier. Assuming the collisions, involving the 3 fatalities, but listed as injury collisions are like other fatal collisions, allows us to identify 3 collisions, with 3 fatalities, 9 injuries and 30 vehicles involved among injury collisions. Transferring these collisions from injury to fatal collisions would increase fatal collisions 1 Each fatal collision includes 1.11 fatality, 0.44 major injury, 2.16 minor injury, 1.33 minimal injury and involves the following vehicles by damage level: 0.99 demolished, 0.27 severe, 0.21 moderate, 0.18 light and 0.07 none.

Analysis and Estimation of the Social Cost of Motor Vehicle Collisions in Ontario by 3 (from 30 to 33 collisions) and reduce injury collisions by 3 from (303 to 300). The characteristics of the collision would also be transferred resulting in the increase of 3 fatalities, 9 injuries and 30 involved vehicles to fatal collisions and the corresponding reduction of these characteristics from the injury collisions. Step 4 Transfer of injury collisions involving fatalities to fatal collisions based on characteristics of fatal collisions Collision Severity Fatal Injury Collisions 30 303 Fatalities 30 3 Injuries 90 9 + 200 Vehicles damaged 300 30 500 Fatal Injury Collisions 30 3 300 Fatalities 30 3 Injuries 90 + 9 200 Vehicles damaged 300 30 500 Fatal Injury 33 300 Fatalities 33 Injuries 99 200 Vehicles damaged 330 500 Similarly the model uses the characteristics of injury collisions to determine the number and characteristics of collisions to transfer from the revised PDO category to the injury collision category. However, the correct number of collisions to transfer will vary depending on which severity category of injury is selected to base the transfer. As a result, the decision on the maximum number of collisions needed to transfer all injuries is model determined based on the characteristics of the data. The model transfers injuries in the proportion they occur in these collisions up to the maximum number by severity category initially allocated to PDOs. It also transfers the expected number of vehicles 22 TNS Canadian Facts, Social and Policy Research
