Need for the Research Stormwater runoff from transportation Rights-of-Way (ROW) may contain nutrients (particularly phosphorus and nitrogen) and may contain pathogens (though it is unclear if DOTs are a source that would…
Problem The climate change literature projects that weather conditions and weather patterns could change significantly enough to trigger shifts in land use, economic activity and trade, which would lead to…
This project would look at the use of permeable pavements along shoulders. It would primarily look at the suitability of such pavements from a design, constructability, maintenance, and longevity standpoint. However, it would…
Problem Supply chains are designed for the processing, staging, and carriage of goods to market. Design choices are determined by sourcing decisions, production and competitive requirements, logistical economies, product characteristics, land…
New construction and replaced impervious surfaces will trigger the new LID standard in the future. In implementing the new LID standard, DOTs need a factual basis to assess the feasibility of applying…
Problem An increase in allowable freight tonnage on U.S. highways has been proposed. Such an increase in truck weight could affect greenhouse gases (GHG’s) and other emissions, and the mix of…
Need for the Research Highways can contribute to hydrologic changes with subsequent degradation of streams. Permits and regulations are beginning to require management of stormwater to minimize adverse hydromodification. Traditional methods of stormwater…
Problem Freight movement accounts for approximately 20% of greenhouse gas (GHG) emissions from transportation and is expected to increase in its share. The logistical challenges of freight transportation which involves multiple…
Need for the Research Highways can contribute to hydrologic changes with subsequent degradation of streams. Permits and regulations are beginning to require management of stormwater to minimize adverse hydromodification, but there are no…
TERI Administrator Note: Selected as FY12 NCHRP Project 25-40; estimated completion is April 2014 Background As the surface transportation systems of the nation expand and transportation agencies continue to meet the…
