Analysis and Estimation of the Social Cost of Motor Vehicle Collisions in Ontario<br />
by 3 (from 30 to 33 collisions) and reduce injury collisions by 3 from (303 to 300). The<br />
characteristics of the collision would also be transferred resulting in the increase of 3<br />
fatalities, 9 injuries and 30 involved vehicles to fatal collisions and the corresponding<br />
reduction of these characteristics from the injury collisions.<br />

Transfer of injury collisions involving fatalities to fatal collisions<br />
based on characteristics of fatal collisions<br />

Similarly the model uses the characteristics of injury collisions to determine the<br />
number and characteristics of collisions to transfer from the revised PDO category to the<br />
injury collision category. However, the correct number of collisions to transfer will vary<br />
depending on which severity category of injury is selected to base the transfer. As a<br />
result, the decision on the maximum number of collisions needed to transfer all injuries is<br />
model determined based on the characteristics of the data. The model transfers injuries in<br />
the proportion they occur in these collisions up to the maximum number by severity<br />
category initially allocated to PDOs. It also transfers the expected number of vehicles<br />
