TRB Special Report 252 - Policy Options for Intermodal Freight Transportation recognizes that freight transportation is of critical importance to the United States and that intermodal freight transportation is one of the major technological and organizational trends affecting the performance of the sector.
During the last two decades, the importance of freight efficiency to the nation s economy has become more apparent to federal policy makers and has emerged as an increasingly important element of laws and regulations related to surface transportation. In the Intermodal Transport
How can the Bureau of Transportation Statistics (BTS), the nation's newest federal statistical agency, contribute to the work of the U.S. Department of Transportation (USDOT)? What is the appropriate role for such an agency as a part of a major department?
BTS was authorized in 1991 by the Intermodal Surface Transportation Efficiency Act (ISTEA) in recognition of the need for more and better data for transportation officials at local, state, and federal levels. While the USDOT has many long-standing data collection programs for particular transportation modes (highways, rail, air, etc.), it
TRB Special Report 246 - Paying Our Way: Estimating Marginal Social Costs of Freight Transportation is a preliminary examination of whether shippers of domestic surface freight pay the full social costs of the services that they use. This study is intended not to provide definitive answers as to whether shippers pay their full social costs but rather to determine the feasibility of making such estimates.
Freight carriers and shippers do not pay directly for all of the costs of providing freight service. Some costs are borne initially by government, such as the cost of roads and ports
TRB Special Report 236 - Intermodal Marine Container Transportation: Impediments and Opportunities examines where and how government action might assist in overcoming impediments and fostering efficiency in intermodal marine container transportation, especially through technological or institutional innovation.
The report analyzes 10 key issues on which government in the United States affects or can affect the intermodal marine container transportation industry. The issues are: ship procurement restrictions under the Operating Differential Subsidy (ODS) program; federally imposed sh
TRB Special Report 225 - Truck Weight Limits: Issues and Options examines various proposals for changes in truck weight regulations. Truck weight limits have always been controversial. They involve trade-offs between the cost to build and maintain highways and the cost to transport goods by truck, and they have implications for highway safety, traffic flow, and highway finance.
Improvements in highway design and vehicle performance have allowed truck weight limits to be revised periodically and generally adjusted upward, and proposals for further revisions appear inevitable. Beca
TRB Special Report 223 - Providing Access for Large Trucks covers appropriate highways for access, safety, vehicle handling characteristics, pavement service life, access to service facilities, local government access policies, the implementation of access policies, and the definition of terminal.
The Surface Transportation Assistance Act of 1982 attempted to strike a balance between improved efficiency of trucking operations and safety. Since the Act became law, the U.S. Department of Transportation has designated a National Network and all states have enacted access policies. Bec
TRB Special Report 211: Twin Trailer Trucks examines the potential safety effects of the new federal truck size rules (the Surface Transportation Act of 1982 requires states to permit twin 28-ft trailers on Interstate highways and on principal roads). The study also addressed other effects of the new rules on highway transportation including the trucking industry use of twins, safety consequences of twins, pavement wear and other highway features affected by twins, and safety and pavement wear affected by 48-ft long semitrailers and 102- in. wide trucks.
The use of twin trailer truck
