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…
Nationally we have raised awareness and action to address ecological impacts of roads upon wildlife, particularly means to avoid and reduce wildlife-vehicular collisions. This is done by identifying and protecting/avoiding intact…
Plug-in and Hybrid Electric Vehicles (EVs) reduce oil imports. However, the current transportation infrastructure is not optimized for EVs. Without new technology and infrastructure, capital and operational barriers will harm the “Plug-In”…
Currently, to implement Eco-Logical, it is critical to either implement or adopt a Regional Ecosystem Framework (REF) or a Watershed Plan for the transportation/conservation planning area. Currently there are many…
Generalizations have been made as to (re) using shingles in HMA and WMA pavements. The engineering opimization of RAS has only been touched upon as to setting limits of RAS replacement. Grade…
