Incorporating Wildlife Crossings into TxDOT's Project Development, Design and Operations Processes

As Texas human population increases, vehicles and wildlife increasingly intersect, with detrimental economic, ecological, and safety-related consequences. TxDOT has not assessed the magnitude of the animal-vehicle collision (AVC) problem in Texas nor created policy to reduce these collisions. Situated across thirteen distinct ecoregions, Texas has a wide diversity of wildlife that also pose a potential driving danger. For example, the state’s estimated 3.6 million white-tailed deer provide hunting, recreation, and income opportunities while also being involved in many of Texas’ reported AVCs. From 2007 through 2016, the 73,597 AVCs resulted in 177 human fatalities. This project will examine AVCs in Texas, conduct a benefit-cost analysis of the related costs, and provide a methodology TxDOT staff can use to determine when, how, or why a wildlife crossing and other potential treatments are warranted. The project will review TxDOT manuals and planning processes, and develop recommendations for amendment to its manuals, including specific instructions for addressing wildlife concerns in the planning, construction, maintenance, and daily operations of the agency. These recommendations will be based on the state of the science and practice of transportation ecology across the nation, as synthesized from literature, interviews, and FHWA and AASHTO recommendations and guidelines.
