Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to a congressional request, GAO reviewed the safety of longer combination vehicles (LCV), focusing on the: (1) current extent of LCV use; (2) results of LCV safety studies; and (3) major operational characteristics that affect LCV safety. GAO found that: (1) 20 states allow LCV operation, but they have different restrictions on the types of LCV allowed, the routes on which they can operate, their length, and their weight; (2) LCV safety studies have reached very different conclusions, with some studies finding that multiple-trailer trucks are less likely to be involved in accidents than single-trailer trucks, while other research indicates that multiple-trailer trucks are more likely to be involved in accidents; (3) a lack of adequate truck data and different study methodologies contributed to different research conclusions; (4) LCV safety tests indicate that multiple trailers are more apt to sway than single trailers, require a wider turn path, and are more likely to travel out of their lane; (5) LCV operational characteristics are affected by LCV type, the driver, load distribution, equipment used, and road conditions; and (6) projections of an increase in traffic density and a shortage of experienced truck drivers could impact future LCV safety.

Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to a legislative requirement, GAO reviewed the economic and safety impacts of expanding longer combination vehicles (LCV) operations, focusing on: (1) LCV effects on highway infrastructure; (2) the potential benefits from and industry's use of LCV; and (3) LCV safety concerns. GAO found that: (1) expanding LCV use could increase highway maintenance and construction costs by up to $18 billion; (2) infrastructure changes needed due to expanded LCV use include bridge replacements, interchange improvements, and staging areas for LCV assembly; (3) infrastructure costs could be reduced by limiting LCV expansion to carefully selected routes away from major population areas; (4) expanding LCV use would not divert significant amounts of freight from the railroads; (5) nationwide use of LCV on interstate highways would reduce trucking costs by about 3 percent, which would most benefit large companies that combine small shipments; (6) the use of some types of LCV is not likely to increase because of logistics problems and customer demand; (7) LCV have increased stability problems, slower acceleration when merging into traffic, and lower speeds on grades; and (8) LCV have not been a safety problem in low traffic density areas, but expanding LCV use into more congested areas will require careful analysis, stricter driver qualifications, and better monitoring of LCV operations by state authorities.

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 2011 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper shows the economic efficiency of allowing longer combination vehicles in Texas. First, an overview of the truck size and weight policies is explained, with an emphasis on those that affect Texas. Next, LCV operations in other countries are described. Then, an LCV scenario for Texas is chosen, with specific routes and vehicle types. Operational costs for these vehicles are calculated on a cost per mile and cost per ton (or cubic yard) mile. The LCV scenario and the current truck base case are analyzed to find the number of truck trips, the number of mile, and the cost per mile for the chosen routes. These are then compared to estimate the change if LCVs were allowed in Texas.

Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to a legislative requirement, GAO reviewed states' regulation of longer combination vehicles (LCV), focusing on: (1) the availability of state data to monitor the safety of current LCV operations; (2) state requirements for special inspections of LCV equipment; and (3) whether state controls effectively ensure safe LCV operation. GAO found that: (1) states do not have adequate information on LCV operations to identify existing or emerging highway safety problems because they do not compile sufficient data to monitor LCV safety and operation; (2) states do not collect sufficient LCV accident data to calculate accidents-per-mile, differentiate between LCV-trailer types, or monitor LCV-driver performance and compliance with permit requirements; (3) although three states perform special LCV equipment inspections before issuing permits, most states rely on trucking companies and drivers to ensure that LCV equipment meets state safety requirements; (4) although double and triple LCV are included in roadside inspections, these LCV are underrepresented and as likely to fail inspections as other types of combination trucks; (5) states that allow LCV operations have various controls and levels of enforcement; and (6) although eastern states have been able to achieve low accident rates by requiring LCV drivers to have good experience and safety records, western states have not taken sufficient actions to control LCV operations.
