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

Wildlife crossings are areas of concentrated animal movement intercepted by roadways. Animal-vehicle collisions lead to mortality of animals and safety concerns to the motoring public. These collisions can be costly in terms of damage to vehicles, loss of life of people and wildlife, and improving or retrofitting facilities to avoid these adverse interactions needs to be evaluated for efficiency. The Transportation Research Board (TRB) and the Federal Highway Administration (FHWA) have published national guidelines for crossing structures, data collection, and fencing. This research project will allow Texas Department of Transportation (TxDOT) to update its manuals and specifications to make them current with successful practices used nationwide and around the world. To assist TxDOT in addressing these goals, the researchers will incorporate updates and additions for implementing national recommendations for incorporating wildlife crossings related information into TxDOT’s manuals and specifications. They will synthesize TxDOT’s institutional knowledge and undertake reviews to compare TxDOT’s efforts to other state DOTs and FHWA recommendations, to determine practices for design and retrofitting to work best in the context of Texas’ unique natural wildlife diversity and transportation infrastructure. The researchers will then identify appropriate techniques for different species in different Texas biogeographic contexts, provide the costs and benefits, and update TxDOT manuals and documents accordingly.
