Wildlife crossings such as overpasses, underpasses, or culverts designed to help animals avoid vehicle traffic can reduce wildlife-vehicle collisions, protect animals, and help maintain their habitat connectivity. While the benefits…
Is there a negative perception of DOTs if the mowing schedule leaves taller vegetation throughout more of the year and later into the growing season? Does education about the reasoning…
Interseeding (also known as overseeding) can increase flowering plant diversity in grass-dominated stands of vegetation but has rarely been used on roadsides. Research is needed to better understand how to…
Computer Vision is a subfield of Artificial Intelligence (AI)/Machine Learning (ML) that uses image recognition to identify wildlife species. The technology has multiple applications for transportation projects including protected species…
Assess the use of eDNA for detecting the presence/absence of protected species on transportation projects. If the application shows potential for accurate results that would be acceptable to natural resource…
Transportation-related infrastructure affects wildlife in a variety of ways by altering the physical environment. These alterations often negatively impact wildlife through displacement, barriers to movement, and increased mortality. They can…
Background Roadway lighting has been shown to measurably reduce nighttime fatal and other crashes. However, roadway lighting can negatively impact insects and animals through attraction and disorientation or by disrupting…
Background Currently, there is minimal guidance from federal agencies on how to conduct noise and vibration analyses specific to wildlife, which results in differing approaches to noise analyses that may…
This research project will build on research grounded in environmental science to identify and evaluate approaches for improving water quality and watershed performance and to reduce habitat fragmentation and its…
Identify and analyze methods for retrofitting highways with measures to reduce impacts to wildlife. TERI Administrator Note (June 2007): Research Completed (See Below) NCHRP – Evaluation of the Use and…
