Analysis and Estimation of the Social Cost of Motor Vehicle Collisions in Ontario<br />
of delay time would be 6,000*1.5*3 or 27,000 hours. Each hour is valued at<br />
$20.60 for a cost of $556,200.<br />
• Fuel Cost: In this incident, we have two hours of stop time during which we<br />
assume that heating/ air conditioning means that the vehicles idle for two hours<br />
followed by one hour of additional driving time. This means that each of 6,000<br />
vehicles uses 2.25 litres per idling hour plus 5.5 litres per hour for additional<br />
driving time. For two hours stopped and one hour of delayed driving, this is 4.5<br />
idling litres and 5.5 driving for a total of 10 litres times 6,000 vehicles. The total<br />
of 60,000 litres is valued at $0.766 per litre (the 2004 price) for a total of<br />
$45,960.<br />
• Emission Costs: Emissions are calculated from idling time and incremental<br />
driving time for the 6,000 vehicles. Idling emissions are 6,000*490*2 hours,<br />
where 490 is 245 kg doubled and extra driving emissions are 6,000*245*1 hour.<br />
Total emissions are 7,350 tonnes and each tonne is costed at $70. Total emission<br />
costs are $514,500.<br />
• Total Costs: This is the sum of the three costs above for a total of $1,116,660.<br />
This describes how costs are calculated for each COMPASS-reported incident<br />
from the Toronto data.<br />
e) Cost Estimates due to Traffic Delays<br />
The individual cost estimates related to extra time, extra fuel and additional<br />
pollution for each incident in the COMPASS sample were extrapolated to All Toronto<br />
COMPASS (a proxy for Toronto) and to all of Ontario using the factors described earlier.<br />
These costs due to traffic delays are identified in Exhibit III-7. For Ontario, for 2004,<br />
traffic delays due to collisions are estimated to be $251 million due to extra time, $21<br />
million due to extra fuel and $230 million due to additional pollution.<br />
