New technologies have made it possible to collect and characterize large amounts of data through remote sensing and other techniques. Sensors, drones, and powerful data analytics have the potential to…
Highway projects often impact historic buildings and archeological sites, that when funded with Federal-aid funds, triggers Section 106 of the National Historic Preservation Act (NHPA). But those projects develop within…
We wish to ascertain the impact of Japanese knotweed on the stability and lifespan of roads, bridges, and other infrastructure near waterways. Japanese knotweed is one of the world’s worst…
Transportation agencies across the nation are charged with operating and maintaining stormwater infrastructure associated with roadways to ensure runoff is efficiently removed from impervious surfaces and discharged to nearby waterbodies…
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 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…
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,…
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…
Background On January 18, 2017, the Federal Highway Administration (FHWA) published the final performance measure rule (PM3) under MAP-21. This rule, which took effect on May 20, 2017, established CMAQ…
A multi-disciplinary approach to building a national-level historic context for historic roads that will then be used to build state-level historic contexts. Using economy of scale, develop a historic context…
