Analysis and Estimation of the Social Cost of Motor Vehicle Collisions in Ontario
Exhibit III-3 (a section from spreadsheet O2 in the model) illustrates the results of
these transfers among collision severity categories to adjust for fatalities occurring in
injury collisions and injuries occurring in PDOs. The result of these transfers is to
increase the number of fatal collisions by 12 (with a corresponding reduction in injury
collisions) and to increase the number of injury collisions by 11,878 (with a
corresponding reduction in PDO collisions). The total number of collisions is not affected
nor is the number of vehicles involved. However there is a redistribution of collisions and
motor vehicles damaged by collision severity, as well as an increase in fatalities and
injuries to reflect the better data available from the Coroner’s Office (fatalities),
MOH&LTC (major and minor injuries) and Chipman re-analysis (minimal injuries).
Exhibit III-3 Adjusted Data for Ontario Model—Number of Collisions,
Fatalities, Injuries and Damaged Vehicles (2004)
Collision Severity
Fatal Injury PDO TOTAL
Collisions 730 61,814 169,004 231,548
Fatalities 813 813
Injuries:
Major 317 4,961 5,279
Minor 1,574 59,152 60,726
Minimal 968 57,855 58,822
Vehicles damaged:
Demolished 723 13,150 4,107 17,980
Severe 200 27,605 30,903 58,708
Moderate 157 32,436 105,753 138,345
Light 133 32,158 148,879 181,170
None 48 11,258 19,443 30,748
In 2004 and subsequent years these transfers are conducted automatically based
on decision rules influenced by the data.
