Evaluation of Right-of-Way Fence Tags to Reduce Wildlife-Vehicle Collisions

Wildlife-vehicle collisions seriously threaten wildlife populations and contribute to human injuries, deaths, and property loss. Wildlife crossing structures (WCS) in Arizona have been shown to reduce such collisions (Gagnon et al. 2011). However, highway reconstruction budgets are limited and result in time constraints that may delay building additional crossing structures. Fence tags may provide a viable alternative to preventing vehicle collisions with elk and deer. Such tags cost less than permanent crossing structures and even rival the costs for the more complex alternatives listed above. The research objectives of this project: Since fence tags have not been rigorously tested to determine their degree of effectiveness with elk and deer, ADOT needs to thoroughly evaluate their potential safety impact on the rate of vehicle collisions with large wildlife. (1) Install fence tags along selected stretches of interstate highway (such as Interstates 17 and 40) where elk-vehicle collisions are prevalent and analyze relevant crash data over the testing period. (2) Evaluate maintenance needs of fence tags through monthly inspection and replacement. (3) Identify locations along ADOT roads for further testing or future implementation based on prevalence of elk-vehicle collisions.
