Transportation costs constitute an important part of total logistics costs and have a dramatic impact on all kinds of decisions across the supply chain. Accurate estimation of transportation costs can help shippers make better decisions when planning transportation budgets and can help carriers estimate future cash flows. This study develops a forecasting model that predicts both contract and spot rates for truckload transportation on individual lanes for the next seven days. This study considers several input variables, including lagged values of spot and contract rates, rates on adjacent routes and volumes. The architectural approach to short-term forecasting is a neural network based on Nonlinear Autoregressive Models with eXogenous input (NARX) models. NARX models are powerful when modelling complex, nonlinear and dynamic systems, especially time series. Traditional time series models, including autoregressive integrated moving average (ARIMA), are also used and results from different models are compared. Results show that the NAR model provides better short-term forecasting performance for spot rates than the ARIMA model, while the ARIMA model performs slightly better for contract rates. However, for a longer-term forecast, the NARX model provides better results for contract rates. The results from this study can be applied to industrial players for their own transportation rate forecasting. These results provide guidelines for both shippers and carriers regarding what model to use, when to update the model with new information, and what forecasting error can be normally expected from the model.

Full textAbstract:
The United States trucking industry underwent deregulation starting in 1980. There was much opposition to the process in fears that trucking companies would be adversely affected by increased competition. There were also many proponents and researchers who proved that the increased competition due to regulatory reform only helped strengthen the industry by forcing firms to become more cost efficient. There has been similar opposition and support for the trucking provisions of NAFTA. Although the provisions have not been fully implemented, the trucking industry is well aware it will only be a matter of time. In early 2002 it was announced that the process to begin implementing the trucking provisions would begin in mid-2002. Many in the industry and other groups have opposed implementing the
provisions, concerned that U.S. trucking firms would be subject to competition from Mexican firms, just as they feared trucking firms would be adversely affected by deregulation more than 25 years ago. This thesis analyzes the effects the 2002 announcement of the process to begin implementing the trucking provisions has had on the cost structure of the industry. It uses a translog cost function to determine if firms have become more efficient in the years following the announcement in anticipation of increased competition from Mexican firms after the provisions are fully implemented. The translog cost function is used to determine what effects the NAFTA variable has had on costs and what specific operating characteristics have caused the costs to increase or decrease.

How an owner-operator chooses a specific load is a relatively unstudied field in transportation literature. Stakeholders in the decisions, such as freight brokers, stand to benefit from a better understanding of the selection process. Using load board data from a freight brokerage, we identified four parameters available to a carrier when a load is presented: length of haul, revenue per mile (RPM), the probability of finding an onward load from the destination, and the required mileage to reposition to the shipment origin. We also identified preferences of the owner-operators based on experience, literature, and the data, such as owner-operators' preference for long haul routes. We tested selection strategies that disintegrated the four load parameters and incorporated owner-operator preferences in a computerized simulation. We found that strategies combining two or more of the identified parameters provide better results in terms of revenue and utilization (% loaded) maximization. Furthermore, we found that including consideration of the empty repositioning distance was critical to success. Our simulated carriers outperformed peers in the dataset by up to 16%. Carriers can apply these insights to improve their operating strategies. Freight brokerages can apply the quantitative approach to advise their carrier clients and optimize the matching of freight with available carrier capacity.

On-time delivery is a key metric in the trucking segment of the transportation industry. If on-time delivery can be predicted, more effective resource allocation can be achieved. This research focuses on building a predictive analytics model, specifically logistic regression, given a historical dataset. The model, developed using six explanatory variables with statistical significance, results in a 76.4% resource reduction while incurring an impactful error of 2.4%. Interpretability and application of the logistic regression model can deliver value in predictive power across many industries. Resulting cost reductions lead to strategic competitive positioning among firms employing predictive analytics techniques.

This thesis analyzed truckload shipment transactions from 2006 to 2008 in order to compare planned procurement activity to actual procurement activity. The research specifically focused on three costs: Primary, Actual and Market. Primary cost is the cost agreed to pay to the primary carrier and is usually contractually fixed in advance. The actual cost is the cost paid to the carrier that hauls the load and the market cost is the average cost for the lane that a shipper should pay. This market cost is a benchmarking cost available to the shippers. The comparison of planned and actual is important because it helps to develop a strategy that decreases transportation costs by identifying overpaid lanes and carriers and it helps to monitor and make corrective decisions. The research suggests that the matching of planning and execution occurred in less than 10% of the lanes and there are under and overpaid lanes. The execution rendered more than 50% of overpaid lanes and the planning showed a commitment to overpay in 45% or more of lanes. Finally this research proposes ideas to improve the truckload procurement strategy because shippers cannot afford to "plan to waste".

This thesis analyzes the impact on prices and capacity of trucking industry due to the introduction of ELD mandate. This mandate requires truck drivers to record their working hours in a specified electronic device instead of a pen and paper method. This thesis utilizes the change in average truck driver working hours, cost of ELD equipment and distance from origin to destination of truck loads to determine the potential impact on trucking market. The models used provide an estimation of the impact on capacity and cost and the likelihood of impact on the economics of trucking industry.

Full textAbstract:
This research focuses on the development of multi-criteria tools for measuring and analyzing the impacts of recurring and non-recurring congestion on freight corridors in the Portland Metropolitan Area. Unlike previous studies, this work employs several distinct data sources to analyze the impacts of congestion on Interstate 5 (I-5) in the Portland Metropolitan Area: global positioning system (GPS) data from commercial trucks and Oregon DOT corridor travel-time loop data and incident data. A new methodology and algorithms are developed to combine these data sources and to estimate the impacts of recurrent and non-recurrent congestion on freight movements' reliability and delays, costs, and emissions. The results suggest that traditional traffic sensor data tend to underestimate the impacts of congestion on commercial vehicles travel times and variability. This research also shows that congestion is not only detrimental for carriers and shippers costs but also for the planet due to major increases in GHG emissions and for the local community due to large increases in NOx, PM, and other harmful pollutants. The methodology developed throughout this work has the potential to provide useful freight operation and performance data for transportation decision makers to incorporate freight performance measures into the planning process.

Full textAbstract:
Volvo Trucks: A Trucker's Pride The North American trucking industry is in decline. By 2014, the United States is projected to be short 110,000 drivers (Wikipedia). The hardest hit segment is the long-haul sector, due to the difficult lifestyle of the long-haul trucker. Drivers experience long periods of time away from home, mediocre pay, and “miserable” working conditions. In order to revive the struggling industry and refresh the lifeblood of our civilization, the long-haul trucker lifestyle must be made more appealing. This project is a study into how to make the North American Long-Haul trucker lifestyle appealing to future trucker generations through both interior and exterior design. In-depth research found that emotional needs of American long-haul truckers are not being met. Emotional needs are directly linked to the concept of “quality of life”. Therefore, increasing the trucker’s quality of life would help truckers meet their emotional needs and thus help revive the North American trucking industry. Through interviews and questionnaires, pride was determined to be the key emotional need of the American Trucker. These interviews revealed that the best method to appeal to this key emotional need was to rethink the exterior form. It was decided that a design sculpture should be used to illustrate the concept of emotionally appealing transportation. For the interior design, research showed that a trucker’s fundamental human needs were not being met aboard the truck. Expanding the living space on-board and providing truckers access to their basic human needs allow people to truly live life on the road. The Volvo Vision Long-Haul (VLH) helps future truckers take pride in themselves and their lifestyles. Pride comes from the aesthetics of assertive strength and the confident stance of the vehicle. A higher seating position gives drivers a commanding view of the road and the use of noble materials helps drivers feel they live in a quality environment. Onboard, the Volvo VLH maximizes interior space, providing enough room for a trucker to live life on the road. To meet basic human needs, the truck has a shower and toilet onboard, along with a kitchen complete with stove and sink. The lofted bedroom offers feelings of exclusivity and expands upward when the vehicle is parked. This unique expanding space is accessed via a spiral staircase, which stores neatly away when not in use. The Volvo VLH meets the emotional needs of the American long-haul trucker, making the lifestyle appealing to future generations.

Full textAbstract:
This paper analyzes the impact on the productivity of the U. S. interstate trucking industry of changes in the regulatory climate in 1980. Two methods of analysis are used; Total Factor Productivity (TFP) and Neo-Classical Cost Function analysis. The industry's performance in 1978 is compared to the performance in 1982.
Results of the Total Factor Productivity analysis indicate the TFP of the industry in 1982, after deregulation, was lower than that of 1978. However drawing conclusions from this result would be unfounded. TFP analysis assumes constant returns to scale. Cost Function analyses find that the U. S. trucking industry exhibits significant economies of scale. As the trucking industry does not have constant returns to scale, TFP cannot be used to draw conclusions about its economic performance.
The results of the Cost Function analyses are dependent on which model is chosen. The variable measuring the effect of deregulation is either positive or negative depending on exactly what other variables are included in the model. In none of the initial models is this variable found to be significantly different from zero. After deleting six data points which produce extreme residuals and correspond to questionable observations, this variable is found to be positive and significant, indicating increased costs in 1982.Business, Sauder School of

In 1980 Congress passed the Motor Carrier Act, substantially liberating trucking carriers from a federal regulatory structure that had exercised broad economic control over the industry for over four decades. Changes in the industry were swift and extensive. This thesis returns to the transformational period encompassing the deregulatory and post-deregulatory years. Using the Motor Carrier Annual Reports (Form M) dataset, the thesis sets its focus as physical productivity at the firm level, and analyzes the truckload (TL) and less-than-truckload (LTL) sectors separatIy. The Form M dataset covers the years 1977-1992; the baseline for cumulative analysis is set as 1979, the eve of the Motor Carrier Act. The productivity analysis is contextualized within a wider account of industry changes, including substantial declines in unit costs. The thesis goes on to present a framework for understanding how deregulation engendered changes in competition and productivity. Physical multifactor productivity (MFP) growth in the years 1979-1992 is found to average 1.6% p.a. for TL and 1.0% p.a. for LTL. After initial productivity stagnation, MFP growth from 1983 on was 2.0% and 1.7% p.a. for TL and LTL, respectively. This is suggestive of steady improvement in efficiency, if not a productivity revolution. Although productivity growth was modest, it played a significant role in cutting unit costs. Between 1979-1992 real unit costs declined by 39% for the truckload sector; productivity factors were associated with a 17% reduction while input price factors were responsible for a 20% reduction. For the LTL sector, the decline in unit costs was 17%, with productivity responsible for a 7% drop and input price factors, an 11% drop. The unit cost savings enabled carriers to offer lower real output prices to shippers.

Multi-stop truckload has been gaining importance in recent years as part of a shift away from Less-than-truckload freight. In our research, we sought to understand how the price and carrier behavior vary as the number of stops increases. Rational economic theory says that these shipments will be more expensive, and experience shows that in practice they also tend to get rejected more often. This thesis tested these two likely results together with other factors known for affecting price and rejection rates, such as lead time, clustering of the stops, etc. We used logistics regression to predict the acceptance ratio and ordinary least squares regression to model the price based on historical data. We found that there is an inherent cost associated with multi-stops, which depends on the number of stops and whether the stop is a pick or a drop. The proximity of these stops as well as the stop-off charge can also impact the price. Carrier acceptance and routing guide depth depends on the price structure and load characteristics. As the number of stops increases, it takes longer for a tender to be accepted and the shipment performance also deteriorates with an increased likelihood of late delivery especially if the initial pickup is late. Therefore, companies need to be aware of the hidden costs associated with multi-stop truckloads as they plan their transportation network.

Understanding policy impacts on freight is essential for planners who have overlooked this transport group in the past and must evaluate new congestion alleviation policies with respect to regional economic and social goals. Since urban areas are limited in infrastructure expansion and travel demand continues to rise, congestion pricing is a potentially compelling policy alternative. This thesis focuses on measuring the impacts of congestion pricing policies on urban freight. We differentiate from prior studies which measure the impacts of urban freight and present tools to measure the impacts on urban freight according to three stakeholder groups: shippers, carriers, and the public sector. We recognize that the impacts of urban freight may be the motivators for policy change or project implementation and the continued study of these impacts is critical to the public sector who aims to minimize externalities of increasing truck traffic (and is also an urban freight stakeholder); however, we suggest that the impacts that these projects or polices have on freight is particularly important given the economic value associated with goods movement. For each of these stakeholder groups, we evaluate their goals, enumerate the possible responses to the scheme, and provide tools to quantify the impacts. First, we summarize the experiences of urban freight in other congestion pricing schemes and review several implementation decisions from the perspective of freight stakeholders. Second, we characterize possible freight responses to transportation improvement policies. Third, we expand previous freight impact analyses by quantifying the first-order impacts of the scheme for each stakeholder group.
(cont.) Finally, we propose additional research extensions related to analyzing the higher-order impacts of freight and using the methods here as a means to introduce public- and private-sector collaboration.

Typically, small businesses have encountered issues with sustaining their enterprise for longer than 5 years after inception, which can adversely affect the prosperity of the communities in which the businesses operate. The purpose of this multiple case study was to identify and explore strategies some owners of small business trucking companies used to achieve profitability and longevity for longer than 5 years. The population of the study consisted of owners of 4 small business trucking companies located in Northern Virginia, who demonstrated profitability and longevity for longer than 5 years of operation. The conceptual framework for this study was systems theory. The data for the study came from semistructured interviews, and review of companies' documents. The data analysis process consisted of organizing the data, interpreting the data, and identifying the themes. After verifying the themes through methodological triangulation, 3 themes emerged: relationship building, passion and commitment, and access to capital. The findings, conclusions, and recommendations from this study could effect social change by providing profits to the small business trucking owners for sustaining and aiding employees, families, and their communities' economies.

Full textAbstract:
Leaders of small trucking businesses who fail to reduce operational cost and increase profitability can experience reduced profits and sustainability challenges. During the first 2 years of operation, 75% of small trucking businesses in the United States fail. The purpose of this single case study was to explore the strategies that successful leaders of small trucking businesses implemented to retain talented employees after downsizing. Transformational leadership was the conceptual framework for the study. The population for the study included 3 business leaders in a small trucking business in the southeastern region of the United States who had successfully reduced operational costs and increased profitability. Data was collected from semistructured interviews with leaders of the small trucking business and from reviewing artifacts such as the company's documents. Yin's 5 steps of data analysis, the tenets of transformational leadership, and member checking were used in identifying key themes. These 5 themes emerged from the analysis of data: applying transformational leadership, finding dependable drivers, establishing trust, rewarding and recognizing employees, and competing with trucking industries that seek to gain competitive advantage. The application of findings from this study might contribute to social change by enlightening leaders of small trucking companies about what strategies reduce operational costs and increase profitability in the small trucking industry.

Full textAbstract:
The raw forest products transportation sector is inherently unique when compared to other transportation industries. The loggers and contractors who transport raw forest products are at a competitive disadvantage. Older equipment is also commonly used by the raw forest products transportation industry in harsh working environments. The average log truck age is 9.7 years while all trucks average only 3.9 years. Nineteen percent of log trucks are 15 years old or older while only 5.9% of all trucks are older than 8 years. Log trucks are regulated by both the Federal Motor Carrier Safety Administration and the state that the truck operates in, thus making interstate transportation more difficult. In addition to these challenges, there is a lack of information concerning efficiency and productivity improvement opportunities related to transporting forest products. This study evaluated truck turn times at both the harvesting site and mill facilities in order to identify important trucking productivity factors and efficiency improvement opportunities. Regression equations were created to estimate truck turn times at harvesting sites and mill facilities. Gross level studies found that 1268 truck turns at the tract scale averaged 1.40 hours while 576 truck turns at the mill scale averaged 0.56 hours. Elemental time studies at four harvesting locations found that log trucks were idle 32% of the time. Trucks spent 29% of time being loaded and 26% of the time waiting. Elemental time studies at mill facilities found that trucks were idle 27% of the time. Trucks spent the greatest amount of time unloading while unbinding was the second greatest contributor to turn times. Reductions in loading and waiting times can have significant effects on the overall turn time.
Harvesting contractors could benefit from maintaining balanced harvesting crews. Estimates indicate that harvesting contractors could earn an additional profit of $106,500 over a period of five years by purchasing an additional skidder for those crews whose production is limited due to a lack of skidding capacity. It is estimated that if adding an additional trailer to harvesting crews would allow an additional 2 loads to be transported to the mill each day, harvesting crews could earn an additional $22,100 per year of profit. Road construction can also affect harvesting contractors profits. By minimizing road construction through the use of easements and improved pre-harvest planning, harvesting contractors could reduce road construction costs by as much as $14,000 per tract.
With tools available to estimate truck turn around times, harvesting contractors, fleet managers, and truck drivers will be able to make more informed decisions regarding fleet management. This will enable those owning and operating trucks to operate in more efficient and profitable manners. The models created during this study will allow managers to estimate tract and mill turn times so as to better allocate trucking resources.Master of Science

Full textAbstract:
This study is designed to gain a better understanding of the decision process of freight shippers who use commercial truckers. Pursuant to this study, it is possible to gather some insights into the phenomenon of the selection of a trucking company to transport goods. Planning is essential to the attainment of goals in any type of firm, and that is especially true in the volatile environment of commercial trucking. Development of the external environment of trucking is prerequisite to the planning process and essential to the attainment of goals. The external environment of a trucking firm is generally represented by economic, social, and political influences, which extend specifically to the nature and tendencies of its markets, i.e., the shippers.

Full textAbstract:
The recent expansion of air trucking operations in Europe has put a strain on the traditional concept of air carrier's liability.Short-haul pick-up and delivery services have gradually given way to a more complex pattern of hubbing and substitute transport by road, possibly undertaken without consent of the consignor of the goods.
In the absence of a set of international rules for multimodal transport, each segment is subject to a separate legal regime. An evolutive interpretation of the original Warsaw Convention, though, fits the newly developed bimodal operations prima facie into the sphere of air carrier's liability.
Problems of delay are dealt with using an elaborate model on the concept of time in the several branches of transport law. The spectrum is completed by a discussion on the plurality of the parties involved in the entire process.

This thesis focuses on the study of the carrier-shipper relationships in the US trucking market. It uses data provided by a leading third party logistics (3PL) company to explore and determine whether a relationship exists between the prices charged by the carriers and the performance that they provide to the shippers. The performance metrics defined in the thesis are measured in three dimensions: on time pick-up, on time delivery, and acceptance ratio. The research uses ordinary least square (OLS) regression to study the effect of the performance parameters on the cost per load of a shipment. The research demonstrates that there is a mild relationship between on time delivery performance and price. With increase in on-time delivery performance, the price increases till a threshold is reached, beyond which it stabilizes. We found that a relationship exists between on-time pick-up and delivery. Since carriers who pick up late are able to deliver on time 80% of the times, the research could not find a direct relationship between on-time pick-up and price. The research also found that increased lane loyalty from a shipper to a carrier can lead to lower rates.

Full textAbstract:
The material transport system in an open pit mine significantly affects the capital and operating costs. All truck haulage is the most common and is a reliable and flexible transport system. On the other hand, this system is very expensive and can cost up to 50% of total mining costs. Its cost is continuously increasing due to the inflation of the fuel, tire, and labour expenditures. In-pit crushing and conveying is an alternative transport system which requires a higher initial investment but gives substantial savings in operating costs.
An evaluation of the all truck system versus the in-pit crushing and conveying system has been performed by means of a simulation of both transport systems in the same mine model. Results of the simulation and the data obtained from the feasibility studies provided input for an economic comparison of the alternative transport systems. A cash flow analysis showed that the in-pit crushing and conveying system was competitive with the all truck system, giving a payback within four years and resulting in total costs over 30% lower than those of an all truck system.
Three computer programs, written by the author, have been used to analyse the mine model:
(1) Open Pit Simulation Program - to model a hypothetical mine and simulate its haulage operation over the mine life,
(2) Off-Highway Truck Simulation Program - to simulate the truck haulage on average annual routes in terms of the operating time and fuel consumption for the estimation of the truck fleet size and the fuel cost,
(3) Cash Flow Analysis Calculation Program - to compare costs of the alternative transport systems over the whole period of a mine life.Applied Science, Faculty of

Trucking replaced railroads as the primary link between rural producers and urban consumers in the mid-twentieth century. With this technological change came a fundamental transformation of the defining features of rural life after World War II. Trucking helped drive the shift from a New Deal-era political economy-based on centralized political authority, a highly regulated farm and food economy, and collective social values-to a postwar framework of anti-statism, minimal market regulation, and fierce individualism. Trucking and rural truck drivers were at the heart of what I call the "marketing machine," a new kind of food economy that arose after World War II, characterized by decentralized food processors and supermarkets seeking high volume, low prices, and consistent quality to eliminate uncertainties from the food distribution chain. This marketing machine developed as a reaction against the statist food and farm policies of the New Deal. Government agricultural experts-economists, engineers, and policymakers-encouraged the growth of highway transportation in an effort to redefine the "farm problem" as an industrial problem, an issue to be solved by rural food processors and non-unionized "independent" truck drivers rather than price supports or acreage controls.

(cont.) Many Class I railroads disappeared and severe competition bankrupted many small carriers in the trucking industry. Larger trucking carriers gained market dominance. Real wages in the trucking industry fell. The size of the railroad labour force decreased while railroad wages remained stagnant. Based on numerous pre-deregulation indicators provided by the government, industry, and academia, this essay shows that deregulation did not fulfill many of the promises made prior to the Staggers Act and the Motor Carrier Reform Act.
The Interstate Commerce Commission successfully implemented its 1887 mandate of reducing the monopolistic powers of the railroads. However, as freight transportation evolved into a competitive system with the emergence of trucking, the ICC effectively adapted its policies. ICC minimum rate regulations and track abandonment procedures kept many Class I railroads competitive. ICC ownership certificate requirements reduced destructive competition in the trucking industry. The blame assigned to the ICC for railroad problems was exaggerated. The Penn Central bankruptcy showed that the railroads had a variety of non-regulation related problems; including rigid management, poor attitudes towards passenger rail services, and inadequate merger planning. This exaggeration was part of a wider misrepresentation as indicated by the attempt to portray Northeast railroad problems as a system-wide problem. This essay shows that there were in fact, many profitable railroads prior to deregulation. Before the passage of the Staggers Act and Motor Carrier Reform Act in 1980, the ICC witnessed the survival of the railroads and truckers through significant economic and political changes, including increased competition, evolving industrial markets, high interest rates, inflation, urbanization, and two World Wars. This was all done while allowing the overall transportation network to evolve into a ubiquitous, competitive system. Deregulation did not achieve several of its stated goals. Freight rail profits were flat and trucking profits fell. The railroads remained unfavourably viewed by Wall Street investors as annual capital investment shortfalls mounted.

Full textAbstract:
An examination of land freight transport in Australia shows that a diverse range of influences
have shaped its development and structure over time. Parochial political interests have
constituted a potent input into the development of policy, made possible by the federal structure
of the Australian governmental structure. Australia is in no way unique in this sense, but the
structure and its constituent elements have, over time, resulted in the development of land
freight transport policy which has proven, in some respects, to be inefficient and ineffective.
Despite a perception that land freight transport policy has been inadequate in the past, attempts
to comprehensively reform the regulatory framework in which the land freight transport task is
undertaken have not proved successful. This has been partly due to constraints imposed by
institutional forces beyond the reach of policy makers. More recently, however, changes in
institutional constraints provided an opportunity for reform to be initiated. Coupled with a
commitment on the part of constituent governments to seek economically efficient national
solutions, changes have occurred in the regulatory environment for land freight transport in
Australia.
The nature of the economic relationships underlying the freight transport task are examined,
and a modelling framework developed for analysing the freight transport task within a spatial
equilibrium framework. Although not applied directly to the issue of concern in the present
study, the technique represents a useful tool to analyse freight transport relationships in the
future. In lieu of the direct application of the spatial transport equilibrium model developed,
previous Australian studies are reviewed and inter-state land freight transport demand
relationships estimated.
The economic implication of regulatory and competition reforms are assessed in the context of
a federal structure of government, and a scenario in which the freight transport task represents
a diverse set of activities. The study concludes that although the reforms offer opportunities to
enhance the regulatory environment for land freight transport, the results to date do not show
unambiguous gains from the changes which have occurred, or which are envisaged.
Moreover, considerations other than cost-benefit considerations may undermine the persuasive
arguments on which much of proposed reforms have been premised. This is likely to lead to
misguided policy which, in the long run, does not prove to be welfare enhancing, and which
may not correspond with the institutional framework underlying the Australian federal
structure.

Full textAbstract:
Air pollution is a threat to the environment and human health. Freight trucking in particular is the main source of freight transportation emissions. Heavy-duty trucks emit large amounts of toxic air pollutants that cause serious diseases and harm public health. In addition, heavy-duty trucks emit great amounts of greenhouse gas (GHG), which is the leading cause of global warming. Despite increased environmental restrictions on air pollution and rising trucking greenhouse gas emissions in the past decades, no economic study has examined the potential GHG and air pollution reductions in the trucking sector and the associated private abatement costs to the industry. This study accounts for GHG emissions and toxic air pollutants in measuring and evaluating efficiency and productivity for the trucking industry in the 48 contiguous states. Moreover, the private costs of abatement to the industry were also estimated. When only GHG was incorporated in the production model, the results showed that each state could expand desirable output and reduce GHG by an average of 11 percent per year between 2000 and 2007. The Malmquist-Luenberger productivity indexes showed that omitting or ignoring GHG in trucking service production yielded biased estimates. On the other hand, due to increased environmental regulations, most of the toxic air pollutants decreased dramatically between 2002 and 2005. The analytical results showed that inefficiency decreased during this period. The private costs of abatement averaged $73 million per state in 2005. When GHG and six toxic air pollutants were incorporated in the production model, the estimated private abatement cost was $76 million per state, which was equivalent to 0.7 percent of the industry output in 2005.

Full textAbstract:
Many changes have occurred in the United States trucking industry over the last thirty years. This study examines the effects of these changes by looking at three related themes: life on the road and life at home, body image and bodily health, and the experiences of women and sexual minorities in the industry. This research is based on a discourse analysis of interviews conducted with truck drivers and trucking industry leaders.
Most truck drivers say that they value the independent nature of their workplace. Yet the independence that is a part of the trucker mystique is challenged by increased surveillance and the availability of more invasive surveillance technologies to motor carriers and the United States government. At the same time drivers face long periods of time away from home and they experience disconnection from their families. Families must learn to adapt to the absence of their trucking loved ones which is a difficult task. However, sometimes these adaptations can result in positive changes for partners at home, such as increased independence and more authority in the home.
The bodies of truck drivers are also examined. Many drivers believe that their image as workers has taken a turn for the worst and the bodily presentation plays an important role in image. Drivers seek to set themselves apart from drivers who they think perpetuate negative images of their industry through sloppy dress and a lack of professionalism. At the same time, there is increasing evidence that the working conditions of this industry lead to unhealthy bodies that are diseased and worn out.
Finally, very little has been written about women or gays and lesbians in this workplace. Women represent only five percent of this industry and they face significant barriers to surviving in this occupation because many male workers seek to marginalize them through exclusionary practices like sexual harassment. Members of the LGBT community are represented in the industry and find both comfort and exclusion in trucking. This work also examines the sexual subcultures in trucking such as sex workers and truck chasers.

Full textAbstract:
A computer simulation model was developed to represent a logging contractorâ s harvesting and trucking system of wood delivery from the contractorâ s in-woods landing to the receiving mill. The Log Trucking System Simulation model (LTSS) focuses on the impacts to logging contractors as changes in truck turn times cause an imbalance between harvesting and trucking systems. The model was designed to serve as a practical tool that can illustrate the magnitude of cost and productivity changes as the delivery capacity of the contractorâ s trucking system changes.
The model was used to perform incremental analyses using an example contractorâ s costs and production rates to illustrate the nature of impacts associated with changes in the contractorâ s trucking system. These analyses indicated that the primary impact of increased turn times occurs when increased delivery time decreases the number of loads per day the contractorâ s trucking system can deliver. When increased delivery times cause the trucking system to limit harvesting production, total costs per delivered ton increase. In cases where trucking significantly limits system production, total costs per delivered ton would decrease if additional trucks were added.
The model allows the user to simulate a harvest with up to eight products trucked to different receiving mills. The LTSS model can be utilized without extensive data input requirements and serves as a user friendly tool for predicting cost and productivity changes in a logging contractorâ s harvesting and trucking system based on changes in truck delivery times.Master of Science

This study was a concurrent validation of a paper and pencil test battery used at a national trucking company. Forty-eight driver managers were rated by their immediate supervisors with the performance appraisal covering 12 dimensions of job behavior that was developed by the experimenter. The driver managers were also administered the Wesman Personnel Classification Test, the Watson-Glaser Critical Thinking Appraisal, and the California Psychological Inventory (CPI). A biographical information blank was also developed and validated. Most validity correlations were nonsignificant, with the exception of the Dominance scale r = .25 (p < .05), the Self-control scale r = -.25 (p < .05), the Communanlity scale r = .29 (p < .05), and the Flexibility scale r = -.39 (p < .05), with overall performance.

Full textAbstract:
With an increasing number of transport operators seeking permits to operate nonstandard
or purpose-built vehicle types, information is required to assist road authorities
to determine which vehicle types could operate on the road network without
compromising the safety of other road users.
A project was created by ARRB TR to develop guidelines for determining route access
for heavy vehicles. This project was developed in conjunction with the state road
authorities, the National Road Transport Commission and the transport industry to
obtain an understanding of the road space requirements for a range of common vehicle
types. This project is the subject of this thesis.
Two series of field experiments were conducted with six common heavy vehicle types
on public roads west of Parkes NSW. Information collected during these full-scale
experiments was used to increase the knowledge of the dynamic behaviour of these
vehicles and to develop model route access guidelines. Data obtained from these field
experiments also provided information to validate computer models and simulation
outputs.
This thesis showed that:
1) There was experimental evidence to demonstrate that vehicle lateral movement is
excited by differences in vehicle wheelpath profiles (point-by-point pavement
crossfall), which make a contribution to trailing fidelity (swept width), offtracking
and swept path;
2) Vehicle type and speed are prime influences on the lateral movement of the rear
trailer and therefore an important input into the model route access guidelines.
Notwithstanding the practical and safety implications of applying different speed
limits for various vehicle types, speed is a prime contributor to vehicle lateral
movement and should be considered when determining route access;
3) Limited lateral position information suggested that one driver of two vehicle types
position the vehicles so that the tyres on the rear trailer track on the sealed
pavement and not on the pavement shoulder;
4) Based on a statistical analysis of the data obtained from the small sample which
only considered the average crossfall of each test section the relative importance of
the key parameters was (highest to lowest), IRI, vehicle speed and vehicle type.
It was shown that good estimates of lateral movement can be obtained using a double
integration technique of the measured lateral acceleration, without applying
compensation for the trailer roll or the pavement crossfall.
It is recommended that route access guidelines be developed using the lateral
performance of a larger sample of vehicles in each class of heavy vehicles operating
over a larger range of road types. The route access guidelines should contain a matrix
of information on vehicle type/length, pavement condition roughness/profile and lane
width. This would provide operators and regulators with a desk-top assessment tool for
determining route access.

Full textAbstract:
My thesis provides evidence supporting a theory asserting that the high level of competition that exists between motor carriers operating within long-haul trucking is the most significant factor contributing to the continuously high driver turnover rates affecting the entire logistics industry. I explore how long-haul truck drivers internalize the conflict between their identity and the aggressively competitive environment within which they work. Social science authors, industry reports, and truck driver feedback from my own ethnographic study are analyzed for contexts in order to explore the current operating definition of success for motor carriers in both monetary and human terms.
