APPENDIX A: DETAIL ON CALCULATIONS OF THE ONTARIO<br />
MODEL<br />
This chapter describes the Ontario model.<br />
A. RAW DATA<br />
Raw data for the Ontario model comes from ORSAR. Exhibit A-1 presents the<br />
data for 2004 data.<br />
Exhibit A-1 Raw Data for Ontario Model—Number of Collisions,<br />
Fatalities, Injuries and Damaged Vehicles (2004)<br />
Collision Severity<br />
Fatal Injury PDO TOTAL<br />
Collisions 718 49,948 180,882 231,548<br />
Fatalities 799 799<br />
Injuries:<br />
Major 245 3,320 3,565<br />
Minor 330 29,589 29,919<br />
Minimal 189 39,338 39,527<br />
Vehicles damaged:<br />
Demolished 678 10,023 5,883 16,584<br />
Severe 188 21,021 32,110 53,319<br />
Moderate 147 24,698 99,313 124,158<br />
Light 125 24,486 137,512 162,123<br />
None 45 8,572 19,161 27,778<br />
Unknown 58 5,420 37,511 42,989<br />
This raw data is entered into spreadsheet O1 and forms the core data used in all<br />
subsequent adjustments. In future applications, users will enter ORSAR data for other<br />
years to replace the 2004 data. Adjustment factors (developed based on the 2004 data)<br />
are applied to other year’s data automatically. These adjustments are discussed in the next<br />
section.<br />
Note that these data do not include collisions that are not reported to police. A<br />
motor vehicle collision does not need to be reported if:<br />
• No personal injury or fatality occurs.<br />
• Damage to vehicles is less than $1,000.<br />
