TRB's Commercial Truck and Bus Safety Synthesis Program (CTBSSP) Synthesis 13: Effectiveness of Commercial Motor Vehicle Driver Training Curricula and Delivery Methods explores the state of commercial motor vehicle (CMV) operator training in the trucking and motorcoach industries. The report examines the experiences of training programs that are using some combination of simulators and computer-based instruction and identifies measures of training effectiveness being used in the CMV community.

Design innovation for electrically powered and hybrid-electric aircraft is accelerating rapidly. While there are many potential benefits of electric aircraft and hydrogen technologies, not all air service can be replaced by electrically powered aircraft in the near term. The TRB Airport Cooperative Research Program's ACRP Research Report 236: Preparing Your Airport for Electric Aircraft and Hydrogen Technologies offers an introduction to the emerging electric aircraft industry, gives estimates of potential market growth, and provides guidance to help airports estimate the potential impacts of electric aircraft on their facilities and to be prepared to accommodate them. A series of appendices provides details on the assumptions and methods used in the research as well as helpful references for airport planning. A toolkit includes a database of more than 100 electric aircraft and may be used by airports to estimate future electric power requirements at their airport based on local characteristics (such as climate, aviation activity levels, existing electrical demand).
