Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Report 671: Review of Canadian Experience with the Regulation of Large Commercial Motor Vehicles examines the process used in Canada to harmonize heavy truck size and weight regulations across the country. The report provides insights on how lessons learned from the Canadian experience might be applied in the United States.

Book Description

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).

Book Description

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.

Book Description

The movement of goods across Canada by road is restricted by different combinations of vehicle weight and dimension (VWD) regulations set by the various provincial and territorial governments. Uniform regulations to facilitate truck movement across the country are of prime concern for both federal and provincial levels of government as well as the trucking and railway industries. Proposed VWD regulation scenarios by the Roads and Transportation Association of Canada (RTAC) have been developed towards this purpose, and in February 1988 the national Council of Transportation Ministers adopted a set of uniform regulations to be implemented acroos Canada. In addition, the four western provinces have agreed to further changes in VWD regulations allowing greater weights and dimensions for road transportation in Western Canada. This study will develop and present a mathematical model using the most recent data available, to forecast the effects of changing trucking service characteristics as a result of these agreements on the market share of freight carried by trucking and railway modes in the commodity classification Fabricated materials, inedible. Model development will involve the use of origin/destination socio-economic indicators and modal service variables in combination with published freight tonnage statistics for interprovincial movement in the Statistics Canada classification Fabricated materials, inedible. The developed model will be used to determine the impact on the freight transportation market of the proposed VWD regulations approved by the Council of Transportation Ministers and those approved in the Western Agreement. This study is an attempt to identify the impact of these proposed regulations on the competing railway and trucking modes. Specifically, the impacts of the proposed regulations on the rail transportation industry and the necessary improvements in its service characteristics to retain rail's existing market share of freight will be determined.
