Economic Cost of Crashes in Idaho

The Idaho Transportation Department (ITD) Office of Highway Safety contracted with Cambridge Systematics (CS) for an assessment of the feasibility of calculating the Idaho-specific economic and comprehensive costs associated with vehicle crashes. Researchers produced two technical memoranda as part of the study. Technical Memorandum 1 reviews methods used to estimate crash costs nationally. The researchers describe “bottom-up” and “top-down” approaches that could potentially be used to estimate Idaho-specific costs. However, because a “bottom-up” approach would require extensive data collection, cleaning, and analysis, researchers recommend that ITD employ a “top-down” approach that relies on US Department of Transportation Value of Statistical Life (VSL) figures. Technical Memorandum 2 provides updated crash cost estimates for Idaho using the recommended “top-down” approach. The researchers also examined how Idaho bears these crash costs from an economic perspective. This process involved estimating how costs split between monetary versus non-monetary outlays and between those involved in crashes versus Idahoans at large. Finally, the researchers characterized potential cost savings that might be achieved by safety investments and resulting crash reductions.
