Next fatal and injury data for each jurisdiction were adjusted to reflect differences
between the number and allocation of fatalities and injuries between the revised and
adjusted data and the raw data for Ontario. As a result, the number of fatalities and
injuries increased and their distribution across collision severity categories changed based
on the observations in Ontario. This allowed us to reflect observations of misreporting
and under-reporting in the Ontario data and the final distribution of human consequences
among collision severities.
The number of collisions and involved vehicles was adjusted across collision
severity in keeping with the methods used in the Ontario sub-models. For example, injury
collisions were transferred to fatal collisions based on the number of extra fatalities that
would have been allocated to injury collisions based on the proportion of demolished
vehicles. The characteristics of fatal collisions and the number of fatalities estimated for
injury collisions were used to transfer an appropriate number of collisions and their
vehicle characteristics. The net result is that the number of fatal and injury collisions and
vehicles involved in them increased and the number of PDOs and vehicles involved in
them decreased.
The results of the adjustments are noted in Exhibit VI-3.
