A brief summary of these mechanisms includes the following: • Driver's Hours of Service per Federal Motor Carrier Safety Administration (FMCSA) requirements: At the end of 2015, FMCSA issued its proposed rule requiring the use of electronic logging devices.

The amount of fuel used to accelerate and stop commercial vehicles can be minimized by reducing the amount of congestion that a commercial vehicle encounters by minimizing overall congestion, rerouting, and driving at alternative times. • Accidents: The National Highway Traffic Safety Administration (NHTSA)

Recommendation 9-2: NHTSA should work with FMCSA to complete additional research on driver influence on fuel consumption, taking into account the newer regulations for electronic logging devices, speed limiters, anti-idling technologies, and the introduction of technologies to reduce the driver influence on fuel consumption. 9.4 COUNTERVAILING FORCES TO FUEL CONSUMPTION REDUCTION While the commercial vehicle freight market has a strong focus on improving costs and reducing fuel consumption, there is also a focus on customer satisfaction.

This has been a force keeping intermodal shipments low, though the size of the market has continued to expand slowly as technologies for managing the mode shifts have been improved. Given domestic intermodal transport replaces part of the freight's journey with rail in lieu of truck, the common decision-making aspect of this mode shift is the savings associated with moving part of the trip with more fuel efficient means -- rail -- with the increased cost of a mode shift, from truck on one end to another truck on the other and the risk of delay.

This is a system issue, though, and one that requires dedication to a long-term strategy with many stakeholders, many of whom consider each other competitors more than collaborators. 9.5.2 Truck-Truck Intermodal Transport A solution that has been considered for nearly half a century, but which is gaining popularity in the United States and abroad, is the development of inland ports (often called freight villages)

While an important component of the overall freight transportation system, the share of freight moving on rivers will continue to be very small. 9.5.4 Drayage Drayage is the movement of goods short distances to enable a mode shift in international or domestic intermodal transport.

. More than a dozen states have gross vehicle weight limits on state roads that exceed the limits on the Interstate and other national truck network routes, and many more states have commodity- or industry-specific exemptions that allow even higher truck weights on specific routes.

For tractor semitrailers, U.S. carriers are disadvantaged by 44 to 53 percent based on available cargo mass capacity, and for double trailer combinations, they are disadvantaged by a factor of 2.

used aggregated fuel use by vehicle class and applied carbon value analysis to estimate the savings that would accrue from an improvement in freight efficiency that results in reduced total truck travel distance. The study noted that the contributing strategies that influence truck transport efficiency include improved loading of the existing truck fleet; increased use of other modes, particularly rail transport, though increased intermodal capacity; and, most importantly, reforming truck size and weight policy with the intended goal of reducing total truck travel distance through consolidation of the freight task.
