The Federal Highway Administration (FHWA) Exploratory Advanced Research (EAR) Program bridges basic and applied research. The EAR Program does not fund projects through commercialization or deployment, and in fact, stops well short. For the EAR Program to be successful, the results must be taken up by the research community, with the support of other government, industry, or nongovernmental funding. Accordingly, the EAR Program is committed to supporting a transition process.
The results of EAR Program-funded projects may include:

Sarnoff Corporation, in an EAR Program funded project, developed a real-time, in-vehicle, stereo vision–based system that detects, recognizes, and tracks pedestrians in the field of view. The layered object recognition system for pedestrian collision sensing can detect and track pedestrians in its field of vision at vehicle speeds of up to 30 mi/h (miles per hour) and up to 35 m (meters) away under good visibility conditions and up to 25 m away under reduced visibility with a 90 percent overall positive detection rate. To perform to the required level for real-life pedestrian detection, system performance must be improved such that detection is possible at vehicle speeds up to 45 mi/h, at distances up to 60 m, under day and evening visibility conditions, in urban and rural settings, and at intersection and nonintersection locations. Commercial implementation would require a market price of not more than a few thousand dollars, which is feasible with the components used in the prototype with sales in the tens of thousands.

Cracks were very shallow when CNF is used, and beams did not fracture through the shallow cracks during the bending test.
Texas A&M University’s Texas Transportation Institute, in an EAR Program-funded project, performed a comprehensive study of past efforts to incorporate carbon nanofibers (CNFs) and carbon nanotubes (CNTs) into cementitious materials to improve the mechanical properties and behaviors of these materials. The tasks performed in the study were important steps toward achieving the ultimate goal of this project: the development of an advanced hardened cement paste that is strong and resists shrinkage cracking under certain levels of restraint.
