RESEARCH THE RELATIONSHIP BETWEEN TRAFFIC NOISE, NOISE WALLS, NOISE REDUCTIONS, TRAFFIC, AIR QUALITY, AND ATMOSPHERIC CONDITIONS VIA 24/7 WEATHER, TRAFFIC, AND NOISE STATIONS.
Stormwater treatment of bridge deck runoff has always been a tough design challenge. Traditional methods of treating bridge deck runoff suggest piping stormwater off the bridge and treating it on…
State DOTs would benefit from guidance that goes beyond the norm on how to conduct modeling for project-level air quality analyses and addresses which modeling inputs are the most cost-effective…
The optimal slope of approaches to highway overpasses for wildlife does not appear to be well documented. Understanding slope constraints could inform the design of overpass structures along the nation’s…
I would like to see a study review the current relevance of Section 4(f) in terms of preservation of historic properties. Has it outlived its purpose, and now acts more as…
The efficacy of scuppers or cutouts in ‘Jersey’ or concrete median barriers on passing wildlife remains untested; yet DOTs utilize scuppers as mitigation for the impacts of constructing concrete median…
The purpose of this study is to demonstrate the use of smartphone sensors for automatically assessing the roughness of pavement and then efficiently managing the pavement network. By developing appropriate…
Transportation agencies generate and then pay to dispose of large quantities of lightly contaminated materials such as street sweepings, gravel shoulder cuttings, and other roadway materials. These lightly contaminated materials…
With rising concerns over climate change impacts and the resilience of urban infrastructures, cities are increasingly held accountable for their total carbon footprint and for their ability to identify and…
Invasive plant species can create nuisance maintenance issues and even dangerous conditions for the traveling public by affecting lines-of-sight, efficiency of roadside drainage, etc. The NCHRP Synthesis Report 341 on…
