Book excerpt: The impact on the Montana state highway system of adopting Canadian Interprovincial, Canamex, or Canamex Short limits on vehicle size and weight was determined. Canadian Interprovincial vehicle configurations were developed based on an investigation of vehicle safety, economy, and damage to the highway system. Canamex and Canamex Short limits are hybrid size and weight systems that retain existing Montana axle weight limits coupled with Canadian gross vehicle weights. All scenarios allow vehicles to operate at higher gross weights than are presently allowed in Montana. The impact of these vehicles on the highway system was determined by a) developing traffic streams that included these vehicles, b) determining the engineering impact these traffic streams would have on existing bridges and pavements and on the future designs required to support these vehicles, and c) assigning a cost to these impacts based on the current cost of equivalent work. These analyses found that 16 to 20% of the bridges system-wide are deficient to carry Canadian Interprovincial vehicles (above and beyond the bridges already deficient under HS20 loads). Incremental deficiencies under Canamex and Canamex Short vehicles are between 1 and 3% of the bridges system wide. The results were found to be sensitive to the assumed level of bridge capacity and the specific segment of the system being considered (i.e., interstate, primary, etc.). Long term pavement demands under all scenarios considered increase by less than 5% compared to demands under the existing traffic stream. Based on these impacts, an increase in equivalent uniform annual cost (EUAC) for bridges and pavements of 12 to 42 million dollars was calculated for Canadian Interprovincial limits. These costs represent a 11 to 36% increase in cost over that projected for the same activities under the existing traffic stream. An increase in EUAC of 4 to 7 million dollars was calculated for Canamex limits, which represents a 4 to 6% increase in cost over that projected for the same activities under the existing traffic stream. Similar but slightly higher costs were determined for the Canamex Short scenario relative to the Canamex scenario. These costs are for the interstate and primary systems. These costs represent an increased cost of 0.01 to 0.18, 0.02 to 0.08, and 0.02 to 0.15 dollars per mile driven on the interstate system by the new configurations for Canadian Interprovincial, Canamex, and Canamex Short limits, respectively. Similar costs per mile driven on the primary system were 1.3 to 10 times higher than these costs.

Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the impacts on the economy of changes in the allowable gross weights of the vehicles that operate on the state highway system in Montana. Four scenarios were considered with different maximum allowable gross vehicle weights (GVWs). Three scenarios, with maximum GVWs of 36,300; 39,900; and 47,900 kg (80,000; 88,000; and 105,500 lb), represented reductions in GVWs in Montana. The fourth scenario consisted of an increase in allowable GVW to 58,100 kg (128,000 lb). Work on the study began with the estimation of the vehicle fleets that would evolve under each scenario, as users and providers of transportation services adjusted to the new GVW limits. Based on these estimated changes in the vehicle fleet and traffic streams, attendant changes in the demands on, and the performance of, the highway infrastructure were determined. Attention was focused on pavements and bridges, as these elements of the infrastructure were believed to be most sensitive to load related changes in vehicle demands. Consideration was also given to possible effects that changes in allowable GVW would have on other aspects of system performance, including geometric and capacity requirements and fatalities and injuries. The investigation subsequently focused on the economic impacts that would be experienced above and beyond changes in direct infrastructure costs. These impacts were first investigated by studying specific industries in the state. A statewide economic model was used to obtain a broader indication than available from the case studies of both the direct and indirect economic impacts that would result from changes in maximum allowable GVW. It was found in the results from both the case studies and the statewide economic model that in many instances the total economic impacts of changes in GVW limits exceeded the associated changes in infrastructure costs by an order of magnitude. This result reinforced the need to consider more than just infrastructure impacts in evaluating truck size and weight issues.

This book was released on 1987 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the completion of the vehicle weights and dimensions research program in 1986, the implementation planning committee was charged with the responsibility of developing a plan to implement regulatory reform that would result in uniformity in interprovincial truck size and weights in canada. this report lays out the recommended principles and limits which were developed in the context of the following objectives: 1) to encourage the use of the most stable heavy vehicle configurations through the implementation of practical, enforceable weight and dimensions limits, 2) to balance the available capacities of the national highway transportation system by encouraging the use of the most productive vehicle configurations relative to their impact on the infrastructure, and 3) to provide the motor transport industry with the ability to serve markets across canada using safe, productive, nationally acceptable equipment. the recommendations cover all aspects of tractor/trailer size and weight limits, including wheelbase, axle spacing, fifth wheel offset, rear overhang, track width, drawbar length, tire and suspension type, and overall height, width, length and weight. this report is a revised edition of the original draft report issued in june 1986 (irrd 291089).

Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the Vehicle Weights and Dimensions Study was to improve uniformity in size and weight regulations in interprovincial trucking in Canada. Once this was achieved, it became evident that there remained a range of related issues which were in need of investigation but which were not directly addressed by this research program. The interaction of trucks with other elements of the traffic stream is such an issue. In 1989, under the sponsorship of TAC's Research and Development Council, work was carried out by a Project Advisory Committee to develop a plan for research which would address the effect of vehicle length on traffic on two-lane, two-way roads in Canada. In January, 1990, a workshop was held to review the state of research and understanding of the preceeding issues, and to identify those which remained as relevant, viable areas for investigation. Consequently, in the spring of 1990 TAC initiated Phase I of this study under the sponsorship of the Research and Development Council and the Council of Deputy Ministers Responsible for Transportation and Highway Safety with the overall goal to : Evaluate the safety and level of service effects of vehicle length on traffic on two-lane, two-way roads in Canada. In January, 1991, the Research and Development Council agreed to sponsor a working session with the project's advisory committee and selected experts in the field. The objective of this session was to decide if the project should continue with a Phase II and if so, prepare the workplan and proposal for this additional work. The following report presents : (i) a summary of the findings contained in the Technical Report; (ii) the results of the working session in light of the objectives outlined above; (iii) implications of the work performed for this project to other TAC committees; and (iv) recommendations from this project's advisory committee to TAC's Research and Development Council. As such, it should be viewed as a supplement to the 1991 Technical Report and read in conjunction with the Technical Report.

This book was released on 1990 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: To help assess proposals for further changes in federal truck weight limits, Congress requested this study through Section 158 of the Surface Transportation and Uniform Relocation Assistance Act of 1987. To conduct the study, the National Research Council convened a special Transportation Research Board committee with experts in pavements, bridges, highway safety, freight transportation economics, motor vehicle design, highway administration, motor carrier operations, and enforcement of motor vehicle regulations. The study focused on four issues identified in the study request that involve potential changes to federal weight limits for Interstate highways: (1) Elimination of existing grandfather provisions; (2) Alternative methods for determining gross vehicle weight and axle loadings; (3) Adequacy of the current federal bridge formula; and (4) Treatment of specialized hauling vehicles--garbage trucks, dump trucks, and other trucks with short wheel bases that have difficulty complying with the current federal bridge formula. For each of these issues, the study committee estimated the nationwide effects of changes in federal limits proposed by the trucking industry, highway agencies, and other groups. Projections of heavy-truck miles by type of truck, region of the country, highway functional class, and operating weight were developed for a base case and alternative truck weight regulatory scenarios. These projections were then used to estimate impacts on truck costs, pavements, bridges, and safety.

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 1989 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: In February 1988, the Canadian Council of Ministers of Transportation and Highway Safety endorsed a Memorandum of Understanding designed to improve the uniformity of regulations covering weights and dimensions of commercial vehicles operating between provinces and territories on a nationwide highway system. Under the terms of this M.O.U., each of the provinces and territories will permit vehicles which comply with the appropriate weights and dimensions specifications documented in section 1 of this report to travel on a designated system of highways in their jurisdiction. It should be recognized that each jurisdiction continues to retain the authority to allow more liberal weights and dimensions or different types of vehicles configurations for trucking operations within their jurisdiction. This document details the size and weight limits contained in the M.O.U., and indicates each case where a more liberal specification is permitted by a particular province or territory.
