Objective: Develop methods to characterize and mitigate harmful effects of non-exhaust (tire wear, brake wear, re-entrained road dust) motor vehicle pollutant emissions to water quality, air pollution, and environmental and…
An increasing number of DOTs and MPOs are considering greenhouse gas (GHG) emissions as part of the planning process, particularly in response to new federal programs addressing on-road GHG emissions.…
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…
Spurred by information on the increasing urgency of mitigating climate change, as well as an injection of federal funding into carbon emissions reduction strategies, transportation agencies are increasingly developing and…
Comparisons of alternative build and no-build scenarios in project-level air quality analyses for NEPA and conformity typically focus on comparisons of emissions and/or ambient concentrations of specific pollutants, including greenhouse…
FHWA regulations for highway traffic noise (23 CFR 772) outline procedures for traffic noise analysis and noise abatement requirements for State DOT highway projects. The regulations stipulate that noise abatement…
The draft findings of NCHRP Project: 20-05/Topic 54-01 Practices to Identify and Mitigate PFAS Impacts on Highway Construction Projects and Maintenance Operations included recommendations to 1) develop a comprehensive guidance…
This research effort will provide a compendium of DOTs Alternative Project Delivery processes as they relate to noise abatement. Several approaches will be undertaken to compile the compendium: • A…
State Departments of Transportation (DOTs) conduct project-level air quality analyses for the National Environmental Protection Act (NEPA) and to meet the requirements of the Environmental Protection Agency’s (EPA) transportation conformity…
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…
