Quantifying the stormwater benefits of mode shift to transit
Most stormwater work focuses on how to manage stormwater generated off of impervious roadways. However, getting people to switch from driving alone to taking the bus takes cars off the…
Role of public transit in high education retention and degree attainment
Anecdotally, many lower-income households rely on public transit for transport. How does public transit access to community colleges and 2-year colleges impact a person’s ability to get to college, and…
Restoration of Construction Impacted Salt Marshes
The University of Georgia, in cooperation with Georgia DOT, has developed a PROPOSED construction standard for use by DOT contractors to better restore the geotechnical properties and ecological functionality of…
Reptile and Amphibian Responses to Directional Fencing
Directional fencing is an important component of wildlife crossing designs. When successful, fencing can guide animals to a safe crossing location and significantly reduce road mortality. Most current research is…
Vegetation Management for Reduced Wildlife-Vehicle Conflict
Wildlife-vehicle conflicts (WVC) are a major safety, mobility, and sustainability concern for transportation infrastructure. Cross-referencing WVC data across states with right-of-way (ROW) vegetation management may yield ROW maintenance recommendations that…
LiDAR, Fish Passage Barriers, and Riparian Mapping Feasibility Study
Fish passage barriers are a significant threat to the recovery of threatened and endangered fish and other aquatic species. There are often limitations to transportation funding that require the prioritization…
Culvert Designs for Terrestrial Wildlife Passage Hydraulic Function
Culvert and bridge design involve safely passing floods and debris while minimizing instability and maintenance requirements. Culverts and bridges also have the potential to reduce wildlife-vehicle conflicts (WVC) by facilitating…
Uncertainty in Project-level Emissions and Air Quality Analysis
When a transportation project is undertaken, an air quality analysis may be required to meet federal and/or state requirements related to U.S. EPA transportation conformity regulations, NEPA, associated FHWA guidance,…
Using Project Level Drive Cycles to Support Air Quality Analysis
The objective of this project is to develop guidance on how to apply microscopic traffic simulation models to project level emissions analysis, focusing specifically on vehicle trajectory information. This project…
