The U.S. Department of Energy (DOE) and the U.S. Department of Transportation (DOT) will collaborate to accelerate research, development, demonstration, and deployment of innovative smart transportation systems and alternative fuel technologies. The agencies formalized this collaborative relationship by signing a Memorandum of Understanding (MOU). The MOU will facilitate coordinated actions to leverage the two agencies’ expertise in transportation energy technology and safety systems to accelerate analysis, tools, and applications of those technologies.
