  3. Study Results • Crash Data • Impacts of Crashes • Cost of Crashes • Minimization Measures • What’s Next

  4. Crash Data

  5. Total WVCs and Total Crashes by Year (Data Source: GES)

  6. Annual WVCs Estimated by Insurance Industry

  13. Costs Of Crashes

  14. Estimated Costs of WVC (Deer, Elk, and Moose) Up to $8 billion annually. Injury, property damage, crash scene response and investigation.

  15. Severity of Injury Distribution for WVCs vs. All Crashes All Collisions WVCs Only 0.5% 0.5% 1.7% 4.3% 0.04% 2.3% 9.4% None None Possible Possible 17.6% Minor Minor Severe Severe Fatal Fatal 68.3% 95.4%

  16. Minimization Measures for Reducing WVCs

  17. Long Tunnels and Long Bridges 100% effective in WVC reductions, but very expensive

  18. Wildlife Fencing 80-99% reported reductions in WVCs Wildlife fencing along US Hwy. 93 on Flathead Indian Reservation, MT

  19. Wildlife Crossing with Fencing 87%average reduction in WVCs

  20. Promising Mitigation Measures to be Further Investigated 2 Most Promising Animal detection Systems Reduce speed by traffic calming or reducing the design speed

  21. Measures For Which Research or Construction Resources Should Not Be Used • Standard wildlife warning signs • Deer reflectors and mirrors • Audio signals in the right-of-way or deer whistles on vehicles • Olfactory repellants • Deer flagging models • Hazing • Intercept feeding • Wildlife relocation in order to reduce population size • Anti-fertility treatment in order to reduce population size • Seasonal road closures • Reflective collars placed on wildlife
