Title:

Collisions, Casualties, and Costs: Weathering the Elements on Canadian Roads

Abstract:

Inclement weather is one of a number of risk factors that affect the frequency and severity of road collisions. Weather reduces road friction, impairs visibility and makes vehicle handling more difficult, all of which translate into elevated risk levels. Using aggregate risk and cost data, a first estimate of weather-related collision costs for Canada was calculated at approximately $1.1 billion per year (Andrey et al. 2001). In the current study, we develop a more detailed methodology for estimating costs, using the national accident database (TRAID3) and cost estimates for injuries of different severities from the literature. We then apply this methodology to four Canadian cities?Winnipeg, Regina, Saskatoon, and Edmonton. Further analysis will extend this to urban areas throughout Canada. Finally, as a complementary analysis, we examine the costs of weather-related road collisions in Winnipeg, using claim information obtained from Manitoba Public Insurance.
