This book was released on 2005-07-14 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB Special Report 267 - Regulation of Weights, Lengths, and Widths of Commercial Motor Vehicles recommends the creation of an independent public organization to evaluate the effects of truck traffic, pilot studies of new truck designs, and a change in federal law authorizing states to issue permits for operation of larger trucks on the Interstates. In 1991, Congress placed a freeze on maximum truck weights and dimensions. Some safety groups were protesting against the safety implications of increased truck size and weight, and the railroads were objecting to the introduction of vehicles they deemed to have an unfair advantage. Railroads, unlike trucking firms, must pay for the capital costs of their infrastructure. The railroads contend that large trucks do not pay sufficient taxes to compensate for the highway damage they cause and the environmental costs they generate. Although Congress apparently hoped it had placed a cap on maximum truck dimensions in 1991, such has not proven to be the case. Carriers operating under specific conditions have been able to seek and obtain special exceptions from the federal freeze by appealing directly to Congress (without any formal review of the possible consequences), thereby encouraging additional firms to seek similar exceptions. In the Transportation Equity Act for the 21st Century, Congress requested a TRB study to review federal policies on commercial vehicle dimensions. The committee that undertook the study that resulted in Special Report 267 found that regulatory analyses of the benefits and costs of changes in truck dimensions are hampered by a lack of information. Regulatory decisions on such matters will always entail a degree of risk and uncertainty, but the degree of uncertainty surrounding truck issues is uunusually high and unnecessary. The committee concluded that the uncertainty could be alleviated if procedures were established for carrying out a program oof basic and applied research, and if evaluation and monitoring were permanent components of the administration of trucking regulations. The committee recommended immediate changes in federal regulations that would allow for a federally supervised permit program. The program would permit the operation of vehicles heavier than would normally be allowed, provided that the changes applied only to vehicles with a maximum weight of 90,000 pounds, double trailer configurations with each trailer up to 33 feet, and an overall weight limit governed by the federal bridge formula. Moreover, enforcement of trucks operating under such a program should be strengthened, and the permits should require that users pay the costs they occasion. States should be free to choose whether to participate in the permit program. Those that elected to do so would be required to have in place a program of bridge management, safety monitoring, enforcement, and cost recovery, overseen by the federal government. The fundamental problem involved in evaluating proposals for changes in truck dimensions is that their effects can often only be estimated or modeled. The data available for estimating safety consequences in particular are inadequate and probably always will be. Thus, the committee that conducted this study concluded that the resulting analyses usually involve a high degree of uncertainty. What is needed is some way to evaluate potential changes through limited and carefully controlled trials, much as proposed new drugs are tested before being allowed in widespread use. The committee recommended that a new independent entity be created to work with private industry in evaluating new concepts and recommending changes to regulatory agencies. Limited pilot tests would be required, which would need to be carefully designed to avoid undue risks and ensure proper evaluation. Special vehicles could be allowed to operate under carefully controlled circumstances, just as oversize and overweight vehicles are allowed to operate under special permits in many states. Changes in federal laws and regulations would be required to allow states to issue such permits on an expanded network of highways, under the condition that a rigorous program of monitoring and evaluation be instituted.Special Report 269 Summary

This book was released on 2008-07-16 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Transportation Research Board (TRB) and the Division on Earth and Life Studies (DELS) have released the pre-publication version of TRB Special Report 290, The Potential Impacts of Climate Change on U.S. Transportation, which explores the consequences of climate change for U.S. transportation infrastructure and operations. The report provides an overview of the scientific consensus on the current and future climate changes of particular relevance to U.S. transportation, including the limits of present scientific understanding as to their precise timing, magnitude, and geographic location; identifies potential impacts on U.S. transportation and adaptation options; and offers recommendations for both research and actions that can be taken to prepare for climate change. The book also summarizes previous work on strategies for reducing transportation-related emissions of carbon dioxide--the primary greenhouse gas--that contribute to climate change. Five commissioned papers used by the committee to help develop the report, a summary of the report, and a National Academies press release associated with the report are available online. DELS, like TRB, is a division of the National Academies, which include the National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council.

Download or read book A Synthesis of Safety Implications of Oversize overweight Commercial Vehicles written by and published by AASHTO. This book was released on 2009 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this report is to identify known relationships between commercial vehicle safety and crash causation factors and to prepare a synthesis of safety implications of oversize/overweight (OS/OW) commercial vehicles. This information can be used to support commercial vehicle enforcement and permitting practices and justify expenditures and investments on size and weight enforcement to enhance safety. In producing this report, insight was gained into the impacts of truck size and weight (TSW) regulations through three case studies. The state of practice in estimating large truck crash rates is complicated because of the many configurations and the wide range of possible weights for any particular configuration. This report highlights four primary findings regarding the contributions of OS/OW to commercial vehicle crashes found by its researchers.

As the book is largely kept at an executive and policy level, it is also appealing to practitioners and policy makers. . . the book is a valuable contribution to the study of intermodal freight transport as a new transportation research application field. It is an essential reading for all stakeholders in the field of intermodal freight transportation, providing them with insight and tools to address the mounting academic and practical challenges in this segment of the transport and logistics market. Theo Notteboom, Journal of Transport Geography This book explores the great challenge of increasing the scope of intermodal freight transport. In view of the current dominant role of road transport and the increasing difficulties in coping with a growing number of vehicles in an efficient and sustainable way, intermodal freight transport could be considered a viable alternative. However, the book makes recognition of the fact that there is still a need to improve the performance of the intermodal transport system. The expert contributors provide an overview of the present role of intermodal freight transport, address opportunities to significantly improve current performance, and demonstrate design and modelling tools used to analyse and support this performance. Requirements for the implementation of intermodal innovations are also prescribed, and policies needed to improve competitiveness are outlined. Many factors contributing to the performance and competitiveness of intermodal freight transport are explored, from technological and organisational innovations through to institutional settings and policy frameworks. This comprehensive range of topics will attract a broad audience including academics, researchers, policymakers and practitioners involved in the design and development of freight transport systems. It will also strongly appeal to those with an interest in the future of freight transport.
