Wildlife Vehicle Collision Reduction and Habitat Connectivity

The objectives of this project are the following: (1) Explore the effectiveness of new mitigation measures intended to increase driver awareness and decrease collisions with large mammals such as deer, elk, and moose. There are an estimated 1-2 million collisions with large mammals each year in the U.S., and the direct costs to society can be as high as $6-12 billion per year. There have been many developments in animal detection-driver warning systems. These are ideal at-grade solutions and are most often deployed on 2-lane rural highways. Other technologies that could be evaluated are on-board animal detection and vehicle-to-vehicle (V2V) systems. Another emerging technology is radar speed guns linked to variable message signs. There are many other emerging technologies that states and their partners may find of interest. (2) Evaluate improvements to traditional mitigation measures and quantify the effectiveness of those improvements in reducing wildlife-vehicle collisions (WVCs). Signage and messaging, reflectors, noise makers, educational campaigns, citizen involvement, structural solutions such as under- and overpasses and associated fencing and escape ramps (a.k.a. jump-outs), and other mitigation measures that may have received modernization or improvements in recent years should be re-evaluated. For example, the Illumination of roadways has been a traditional measure to increase driver visibility, but has not necessarily been aimed at reducing WVCs. With new lighting techniques available, lighting systems may be evaluated for effectiveness at reducing WVCs. Similarly, new innovations in overpass technologies, such as the use of geosynthetically reinforced soil technologies and alternative fill materials like geofoam, may result in increased effectiveness because of improved sound attenuation. The Wildlife Vehicle Collision Reduction and Habitat Connectivity pooled fund study will select mitigation measures from this category to evaluate. (3) Assess the mitigation needs and measures for particular species of conservation interest. Often there is little known about species of conservation concern and their interaction with roads and when and how to create safe passage for these species. This project will select those species of conservation concern for which information is most urgently needed by transportation agencies and its partners, particularly for species of regional or national importance.
