Applications
1. Mitigation planning to reduce vehicle crashes with wildlife and motorists

  • where mitigation (e.g. wildlife signage or crossing structures) should be placed using collision hotspot map
  • when mitigation is needed using collision temporal map
  • type of mitigation, i.e. temporary measures (e.g. modified speed limits) at dynamic hotspot locations and permanent measures (e.g. overpass) at reoccurring spatiotemporal hotspots

2. Species-at-risk recovery efforts

3. Core and corridor validation for natural heritage planning

4. Predictive simulation of collision trends, injuries, fatalities, and property damage

5. Wildlife population trend analysis
