Ontario Model
to the losses through collisions. Exhibit II-4 illustrates the format of the output of the
social cost model.
2. Ontario sub-models
There are four separate sub-models for Ontario, each one formed by sub-sets of
HTA reportable collisions:
• Drinking and driving collisions defined as collisions associated with alcohol
consumption by one or more involved drivers—not necessarily where alcohol was
the cause.
• Collisions involving pedestrians where one or more of individuals involved was
a pedestrian.
• Large truck collisions defined as involving one or more vehicles qualifying as
large truck.
• Motor vehicle collisions on freeways (or 400 series highways).
Each is structured like the Ontario model. However, the raw data of the Ontario
model are replaced with a sub-set of collisions (in OS1—Raw data) meeting the
particular collision characteristics (the number of collisions, fatalities, injuries by
severity, and vehicles damaged by severity by collision severity) of the sub-model
presented above.
The same spreadsheet structure (as illustrated in Exhibits II-3 and II-4) is used.
The only exception is to include an additional spreadsheet (like Exhibit II-4) reflecting a
sub-set of government-only costs (hospital/health care, police, courts, fire and
ambulance) related to motor vehicles collisions on freeways.
