Analysis and Estimation of the Social Cost of Motor Vehicle Collisions in Ontario<br />

C. BASIC STRUCTURE OF THE MODEL<br />

The “model” to estimate the social cost of motor vehicle collisions comprises a<br />

series of models and sub-models, each made up of a series of linked spreadsheets. This<br />

basic structure is presented in Exhibit II-2. Major linkages between the spreadsheets are<br />

identified through arrows—the direction indicating the causal relationship between the<br />

spreadsheets.<br />
