This creative project documents the effects of deregulation on the trucking industry. Through the use of DVD, the viewer learns all about the culture of trucking and the way it has changed in the past 30 years since deregulation. In August of 2006, I logged over 4,000 miles speaking with four different drivers. The result is a DVD consisting of a documentary, video short stories, photo journals, audio recordings and a flash card game, teaching the viewer about the trucking culture. / Department of Telecommunications

Container freight is an important component of the transportation system yet there is little understanding about this issue. This research develops an information system to assist transportation engineers and planners understand container freight transportation in the Canadian Prairie Region. The research conducts a transportation systems analysis to provide information about regional transportation, demand, and flow characteristics of container freight. It also designs, develops, and applies a container truck model to provide information about urban container truck traffic activity. The analysis and model reveal issues that should be considered in defining, evaluating, and choosing among alternative options to improve urban container freight transportation. The transportation systems analysis reveals the following issues affecting regional container freight. The Panama Canal expansion has the capability of altering container freight using the mini land bridge between West and East coast ports although the Port of Prince Rupert is emerging as a legitimate option to the Panama Canal. Railroads are developing integrated logistics centres which often involve relocating intermodal terminals and introducing major container generators to a city. Railroads are operating longer container trains and making fewer stops at prairie cities; however, these cities are developing inland ports to attract international freight. This research produces the first urban container truck traffic model to help overcome insufficient data and information in this area. It comprises defining a container truck network, acquiring container truck traffic data, and estimating container truck traffic volumes. The model is applied to the City of Winnipeg although the following issues are expected to be similar in other prairie cities. The research reveals issues regarding the temporal, spatial distribution, and physical characteristics of container trucks. Overall, about 13 percent of articulated trucks carry containers; however, corridors with high articulated truck volumes do not necessarily have high container truck volumes. Weekend articulated truck traffic volumes are nearly one-quarter of weekday volumes whereas Sunday container truck volumes are similar to weekday volumes. Container truck volumes peak during the midday while articulated truck volumes exhibit an a.m. and p.m. peak. The split between tridem and tandem axle semitrailers is 80/20 for container trucks.

Overloading truck traffic is an untenable problem around the world. The occurrence of overloaded truck traffic can be evidence of rapid development of an economy. Most of the developing countries emphasize the development of economy, thus supporting reform of infrastructure is limited. This research investigates the relationship between truck overloading and the condition of road damage. The objective of this research is to determine the amount of economic loss due to overloaded truck traffic is. Axle load will be used to calculate the total ESAL to pavement. This study intends to provide perspective on the relationship between change in axle load due to overloading and the resultant service life of pavement. It can then be used in the estimation of pavement damage in other developing countries facing the problem of truck overloading. In conclusion, economical loss was found, which include reduction of pavement life and increase in maintenance and rehabilitation (M&R) cost. As a result, net present value (NPV) of pavement investment with overloading truck traffic is higher than normal truck traffic.

The road transport industry is facing a strong need for fuel consumption reduction, driven by the necessity of decreasing polluting emissions, such as CO2 and NOX, as well as coping with strict regulations and increasing fuel costs. For road vehicles the aerodynamic drag constitutes a major source of energy consumption, and for this reason improving the aerodynamic performance of the vehicle is an established approach for reducing fuel consumption and greenhouse gases emissions. In this Thesis work, Computational Fluid Dynamics (CFD) investigations have been carried out in order to investigate and improve the aerodynamic performance of an unloaded timber truck. The work has been divided in two parts. In a first phase, a preliminary study was carried out on a simplified tractor-trailer model in order to establish a suitable computational grid and turbulence model. The hexcore-mesh showed a better performance over the tet- and poly-mesh types. Among the selected RANS turbulence models, the Realizable k − ε with Enhanced Wall Treatment (EWT) and y+ > 30 showed the highest reliability of results in comparison with experimental data and existing CFD investigations. In a second phase, the flow field around the baseline unloaded timber truck was analysed in order to highlight potential regions for drag reduction. The truck cabin-bulkhead gap, bunks, the exposed wheels and the stakes were found make key contribution to the drag build-up. The analysis confirmed the 5◦-yaw case to be the most representative for the wind-averaged drag coefficient. Geometry modifications were implemented in order to improve the aerodynamic performance in the selected areas, and subsequently combined into aero-kits in order to enhance the performance, analysed for the 5◦-yaw case. The combination of extended side skirts, bulkhead shield and collapsed stakes yielded a remarkable result of more than 30% decrease in the wind-averaged drag coefficient, achieved by reducing the flow separation on the cabin leeward A-pillar, and by shielding areas of high stagnation pressure from the side wind. Furthermore, a parallel study was conducted on the development of a procedure for the automatic post-processing of results. The outcome was a set of Python scripts to be used with Kitaware Paraview in order to automatically obtain figures of surface variables distributions, iso-surfaces, velocity profiles, drag build-up and total pressure contours. The procedure was finally extended to include the case comparison. / ETTaero2

Essa profissão tem uma histórica trajetória de desvalorização e pouco reconhecimento, além de condições de trabalho precárias. Até o ano de 2012 a profissão de motorista de caminhão não era regulamentada, ocasionando extenuantes jornadas laborais, sem limite de tempo ou deveres e direitos assegurados. A partir da organização do trabalho peculiar a profissão e das demandas sociais acerca do excessivo tempo de trabalho desses profissionais, em 2015 entrou em vigor a Lei Nº 13.103 com a finalidade de resguardar os caminhoneiros e produzir bem-estar físico, social e econômico. Em vista disso, foram investigadas nesta dissertação as condições de trabalho dos caminhoneiros e as suas relações com a temporalidade laboral. A metodologia utilizada segue o modelo de pesquisa qualitativa e descritiva. O grupo de trabalho é composto por 5 caminhoneiros selecionados através de amostragem por conveniência em espaços públicos da cidade de Parnaíba-PI, até o alcance do ponto de saturação. O procedimento de coleta dos dados se deu através de uma entrevista semiestruturada versando os apontamentos constituintes do fenômeno estudado. A análise dos dados foi feita através da Análise de Conteúdo proposta por Bardin (2011). Nos resultados foram identificadas categorias finais, tais categorias dizem respeito a: organização do trabalho, condições de trabalho, jornada laboral e sobre a regulamentação da profissão e suas implicações na atuação profissional. Em meio às discussões surgidas percebeu-se que as condições de trabalho dos caminhoneiros estabelecem estreitas relações com a organização do trabalho e assumem aspectos como representações negativas, precárias e incompatíveis. No tocante as conexões entre as condições de trabalho e a questão temporal, identificou-se uma disparidade entre a prescrição legal da profissão e o real da atividade. Dessa forma, a atuação dos motoristas de caminhão é marcada por uma organização do trabalho cansativa e estressante; por condições de trabalho precárias na realidade brasileira e pelo predomínio do tempo de trabalho sobre os demais tempos sociais, considerado como origem de adoecimento físico e mental. Nesse sentido, foi pontuada a relação entre a deficiência nos estudos acerca do tema implicado na realidade do Brasil, tendo em vista as especificidades desta realidade e importância da categoria para o funcionamento da economia do país.
