Deer-vehicle collisions are a significant safety hazard on Minnesota roads. While MnDOT strives to employ safety measures on roads at high risk for these collisions, identifying these areas can be challenging. Numerous variables impact where deer are more likely to be present near roads, and many collisions go unreported. A new tool estimates the risk levels—based on road type, geographical features, deer population and other characteristics—for each road segment in the state. In addition, a new method of estimating reporting rates will help MnDOT understand the extent of deer-vehicle collisions in a specific area.
