Problem Current surface transportation systems depend on century-old internal-combustion technology that produces millions of tons of GHG’s and other emissions annually. Highway vehicles produce emissions while idling in traffic and in…
Problem Statement A low carbon fuel standard (LCFS) sets a target to reduce the greenhouse gas (GHG) intensity of transportation fuels. Fuel providers must reduce the GHG intensity of their…
Problem Statement An ever-growing interest in the promise of high efficiency/low greenhouse gas-emittingvehicles has led to a variety of efforts to accelerate their commercial introduction. All the major original equipment…
Problem There are several steps in the freight processing system, from warehousing, manufacture, and distribution that generate trips, usually by truck, between these stages. Often import material is in a disaggregated…
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…
