Cost Benefit Analyses of Mitigation Measure Aimed at Reducing Collisions with Large Ungulates in the United States and Canada: A Decision Support Tool
Wildlife-vehicle collisions seem to be increasing over the last few decades in both the United States and Canada. This set of studies looks at collisions with large ungulates: deer, elk, and moose. The overall cost of the average collision is calculated, and the cost of collision mitigation measures are reviewed to calculate the overall cost-benefit and where the break-even point is to start gaining benefits. The break-even point translate into the number of large animal collisions that need to occur per kilometer per year in order for the mitigation measures to geneerate benefit in excess of the cost. This was calculated and copmared over 10 sections of road throughout the United States and Canada. More in-depth analyses was completed on one road section to better illustrate the cost benefit relationship. All these were used to create a model for cost-benefit analyses that is a valuable decision support tool for determining mitigation measures to reduce wildlife-vahicle collisions with deer, elk, and moose.
