Seasonal Aspects

There are a myriad of laws, regulations, and policies governing the operating weights and dimensions of trucks. In Canada and many northern states, these regulations form a continuum of basic limits, seasonal variations, and overweight/overdimension limits that are legally permitted. This paper deals with the seasonal aspects of weight limits (winter weight premiums and spring weight restrictions) governing trucking within and to and from the prairie region. This region encompasses Manitoba, Saskatchewan, and Alberta, and the northern tier states of Minnesota, North Dakota, and Montana. The paper presents results of research conducted for the transportation departments of the three prairie provinces and Public Works and Government Services Canada. It discusses existing winter weight premium and spring weight restriction regulations, as well as basic weight regulations in the region, and their technical rationale. It examines possibilities for using advanced technologies to help harmonize and rationalize seasonal truck size and weight regulations and enforcement practices, and identifies immediate opportunities for rationalization and harmonization of spring weight restrictions and winter weight premiums.Key words: trucking, weight regulations, spring restrictions, winter premiums, prairie region, harmonization, rationalization.

Indian Residential Schools

Significance The discovery of the bodies of hundreds of children at Canada’s former Indian Residential Schools has unleashed a wave of anger and mourning across Canada’s growing Indigenous population. More discoveries are expected, posing challenges for the country’s economic and social fabric. Impacts Public works projects may slow amid intensified disputes between the Canadian state and Indigenous peoples over lands and resources. There will be more pressure to share wealth from economic activity that directly affects Indigenous communities. Indigenous communities are likely to benefit from greater control over the design and delivery of government services. Cultural and academic institutions will increasingly prioritise and amplify Indigenous voices and perspectives. Canada’s reputation as an advocate for human rights will be affected by its handling of the residential schools issue.

Seasonal Aspects

Abstract An objective climatology of anticyclones over the greater Mediterranean region is presented based on the Interim ECMWF Re-Analysis (ERA-Interim) for a 34-yr period (1979–2012) and the Melbourne University automatic identification and tracking algorithm. The scheme’s robustness and reliability for the transient extratropical propagation of anticyclones, with the appropriate choices of parameter settings, has been established and the results obtained here present new research perspectives on anticyclonic activity affecting the Mediterranean. Properties of Mediterranean anticyclones, such as frequency, generation and dissipation, movement, scale, and depth are investigated. The highest frequency of anticyclones is found over continental areas, while the highest maritime frequency occurs over closed basins exhibiting also maxima of anticyclogenesis. There is a significant seasonality in system density and anticyclogenesis maxima, this being associated with the seasonal variations of the larger-scale atmospheric circulation that affect the greater Mediterranean region.

The Stability

Considering both self-evaluation and peer evaluation, the traditional data envelopment analysis (DEA) cross-efficiency method has been widely used to evaluate efficiency scores. However, it has several defects such as excessive weight flexibility, unstable evaluation, and aggregation irrationality. This paper proposes a novel comprehensive DEA cross-efficiency method where two novel weight restriction methods are used to enhance the stability and feasibility of evaluation. Then, final efficiency scores were calculated through the geometric mean aggregation method. Finally, an empirical example is used to demonstrate that the proposed methods are more reasonable and scientific.

Traditional Performance

Public works agencies are focusing increasingly on the concepts of quality and customer service in response to growing demands for accountability and improved performance. In an effort to gauge customers' satisfaction with the services they provide, state transportation departments are beginning to solicit feedback from their customers to complement more traditional performance measures. This article reports the findings of a large-scale survey of the principal customers of the Pennsylvania Department of Transportation's highway maintenance program. The sample size and the disproportionally stratified sampling strategy were aimed at providing reliable data for 67 individual county-level maintenance units. The results indicate widespread variation in motorists' ratings of road quality, which correlate moderately with more traditional engineering-oriented measures of road quality, but it is clear that they offer a different perspective on service quality, which transportation departments will have to learn more about if they are serious about improving customer satisfaction.

The emerging field of digital fabrication is a process where three-dimensional datasets can be directly transferred to fabrication equipment to create models or even 1:1 building elements. In this paper, we will discuss the results of a collaboration between the Carleton Immersive Media Studio (CIMS), the Dominion Sculptor of Canada, and the Heritage Conservation Directorate (HCD) of Public Works and Government Services Canada (PWGSC), that utilizes digital fabrication technologies in the development of a digitally-assisted stone carving process. <br><br> The collaboration couples the distinguished skill of the Dominion Sculptor with the latest digital acquisition and digital fabrication technologies for the reconstruction of a deteriorated stone bas-relief on the façade of the East Block building of the Parliament Buildings National Historic Site of Canada. The intention of the research is to establish a workflow of hybrid digital/analogue methodologies from acquisition through rehabilitation and ultimately to the fabrication of stone elements.

Intense Debate

Increasing legal limits on the size and weight of trucks allows companies to achieve a higher degree of load consolidation. This reduces the total number of vehicle-kilometres required to distribute a given quantity of goods, saving money and reducing environmental impacts. Proposals to legalise longer and heavier vehicles, (LHVs) have, nevertheless, generated intense debate, particularly in Europe where they are strongly resisted by railway and environmental organisations. This chapter reviews recent studies on this subject, presents an analytical framework and focuses on three critical issues: the extent to which loads can be consolidated in LHVs, their effect on the freight modal split and the possibility that the resulting reduction in road freight costs will stimulate additional traffic growth. Most of the recent studies support the development of LHVs, particularly those based on actual experience of their use in countries such as Australia, Sweden and the United States.

Heat Events

Abstract Temperature and airport elevation significantly influence the maximum allowable takeoff weight of an aircraft by changing the surface air density and thus the lift produced at a given speed. For a given runway length, airport elevation, and aircraft type, there is a temperature threshold above which the airplane cannot take off at its maximum weight and thus must be weight restricted. The number of summer days necessitating weight restriction has increased since 1980 along with the observed increase in surface temperature. Climate change is projected to increase mean temperatures at all airports and to significantly increase the frequency and severity of extreme heat events at some. These changes will negatively affect aircraft performance, leading to increased weight restrictions, especially at airports with short runways and little room to expand. For a Boeing 737-800 aircraft, it was found that the number of weight-restriction days between May and September will increase by 50%–200% at four major airports in the United States by 2050–70 under the RCP8.5 emissions scenario. These performance reductions may have a negative economic effect on the airline industry. Increased weight restrictions have previously been identified as potential impacts of climate change, but this study is the first to quantify the effect of higher temperatures on commercial aviation. Planning for changes in extreme heat events will help the aviation industry to reduce its vulnerability to this aspect of climate change.
