Available in PDF, EPUB and Kindle. Book excerpt: The U.S. economy is expected to double in size over the next 30 years. Truck and rail freight traffic is expected to increase by approximately 45 percent. Air freight is expected to triple in response to demand for the rapid movement of high-value merchandise, while multimodal shipments will likely double. Texas with a gross state product (GSP) of $1.4 trillion dollars is the second largest economy in the U.S. Its size and population, central location, Gulf coastline, and energy resources require a reliable freight transportation system to facilitate further growth. This thesis focuses on the feasibility of Underground Freight Transportation (UFT) to determine the role of UFT in addressing the growing demand for freight transportation in Texas. Underground Freight Transportation (UFT) is a process in which freight is transported in large capsules moving through underground pipelines. As concluded in this thesis, UFT reduces congestion and traffic jams on highways and streets, and increases highway safety by reducing the number of accidents caused by freight trucks, and also reduces highways maintenance costs. To conduct this research, in addition to a comprehensive literature search, a survey on the feasibility of Underground Freight Transportation was performed. The survey was sent to the professionals involved in design, engineering, planning, contracting and regulating freight transportation in the state of Texas. The results of this investigation showed that, due to expected increase in freight transportation in the next couple of decades, UFT can be used as a complementary method of freight transportation to reduce the increased traffic load caused by freight trucks on the road structure.

This book was released on 2022 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A reliable, safe, and efficient freight transportation system is one of the most essential rudiments supporting the continuous economic growth of a nation. The United States (U.S.), as the world's largest economy relies heavily on its transportation and freight movement systems. Population growth and economic activity have created a critical need for freight transportation services. E-commerce and online retailing have effectively challenged conventional freight transportation services, increasing the demand for faster delivery. Underground freight transportation (UFT) systems are an innovative technology that can be a viable solution to satisfy the growing demand for freight transportation services. UFT systems are automated freight transportation systems that utilize space beneath congested roads and urban areas to transfer freight between intermodal terminals. UFT systems can potentially reduce truck volume on congested roads and increase freight movement system capacity, thereby improving security and safety as well as mitigating adverse environmental impacts. Successful implementation of large UFT systems require a detailed investment evaluation to explicitly show planners and decision-makers the economic feasibility of such systems. The main objectives of this study are (1) analysis of financial means and enabling legislations for implementing UFT systems; (2) deterministic investment analysis of implementing UFT systems; and (3) investment valuation of implementing UFT systems under uncertainty using a real options approach. A comprehensive Life-cycle benefit-cost analysis of the UFT systems for five different scenarios of implementing UFT systems in Texas showed that these systems are economically feasible. Results of sensitivity analysis highlighted the most uncertain parameters affecting the economic feasibility of UFT systems. This analysis showed that the economic feasibility of the large and medium size UFTs is more sensitive to construction cost and revenue from shipments. For the first time, a real options approach is used to capture the uncertainties and the available managerial flexibilities in investment valuation of UFT systems. The analysis of historical data showed that the freight rate follows a mean-reverting process. While the stochastic behavior of the construction cost is completely different (a GBM process). Yet, the extant real options methods adopted to transportation infrastructures have theoretical limitations to model UFT uncertainties with different attributes. Therefore, a novel bivariate real options model suitable for the investment valuation of UFT systems under uncertainty is developed. The proposed model estimates the market value of the project at each possible state of time and offers an optimal policy to invest in UFT systems. While the data used and the quantitative results showed in this research may be particular to Texas, the methodology presented in this research can be followed for determining the economic feasibility of UFT systems elsewhere. The findings of this research provide decision-makers with information to objectively appraise UFT projects.

This book was released on 2020 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the increases in freight transportation demand, the current infrastructure for freight transportation appears insufficient. Moreover, the future development of capacity for freight transportation infrastructure seems to be limited. Based on a U.S. DOT report, most of the U.S. freight transportation infrastructure's construction dates back to the 1960s. This puts a heavy burden on the national highway and railroad systems. The growing demand for freight will increase truck traffic on both urban and rural highways. The increase in truck traffic on highways will result in multiple challenges, including traffic congestion, security concerns, infrastructure deterioration, environmental pollution, energy consumption, increase in crash and fatality rates and loss of productivity. An Underground Freight Transportation (UFT) system can play a significant role in meeting some of the future capacity shortcomings in the above-ground freight transportation. UFT offers multiple benefits: decreasing truck traffic on highways, reducing rail traffic, reducing energy consumption, reducing noise and air pollution, promoting safety and security, and enhancing the reliability of freight delivery. A UFT system is an autonomous transportation system that carries freight in individual capsules or flat-bed gondolas within tunnels or pipelines. This research starts with the planning of a UFT system for multiple locations in Texas and then identifies UFT design components. Moreover, this research formulates UFT operational parameters and develops relations among those parameters. Additionally, different propulsion systems have been studied for UFT systems and the required power and energy consumption of the propulsion system is calculated.

This book was released on 2019 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the U.S. Department of Transportation (USDOT), by 2040, nearly 30,000 miles of our busiest highways will be clogged daily and it is important to increase the capacity of our transportation system. Construction of intermodal underground freight transportation (UFT) systems for freight movement through underground pipelines or tunnels, can increase the capacity of the existing shipping network. The intermodal terminal is a major component of the UFT's innovative infrastructure project. Increasing demand for container transportation systems in terminals will raise the risk of terminal congestion and delivery delay due to the increase in freight transportation system bottlenecks (traffic jams and extended terminal loading and unloading wait time) without an equivalent increase of stacking and handling capacity. Thus, it is essential to evaluate the current terminal capacity by studying the effect of different operational components on terminal performance. The objective of this dissertation is to develop a framework for optimizing the capacity of intermodal UFT terminals with discrete event simulation (DES) model. The terminal operations considered include speed, headway, number of gondolas (equipment used for carrying the freight) needed to carry containers, line capacity, number of handlers, stack-yard capacity, the conveyance system (tracks and power requirements), lifting equipment, and drayage performance. The expected annual shipped containers for the UFT system research case study is calculated mathematically and then the UFT system is simulated to build the base-model for this dissertation. For optimizing terminal operations, two different scenarios were simulated to test the variations of performance indicators. Scenario No. 1 considers a terminal with a stack-yard in the form of two small loops and the Scenario No. 2 is in the form of one large loop without a stack-yard. The outputs for all three models base model, scenario number one, and scenario number two are compared with the UFT annual expected shipped containers. The results show the number of shipped containers for Scenarios No. 1 and 2 are respectively 34% and 59% more than the annual expected shipped containers, which are 46% and 73% more than the base-model output. The findings confirmed percentages of base-model bottlenecks were reduced significantly in both scenarios. Additionally, compared with Scenario No. 1, Scenario No. 2, without a stack-yard, can handle 25% more containers per year.

This book was released on 2003 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planning for growth in freight transportation throughout Texas has become a significant challenge, particularly along the Interstate 35 corridor. Reasonably, the expected construction and maintenance expenses required to accommodate this growth led to a four-year research project to investigate the technical and economic feasibility of using a freight-conveying pipeline to reduce highway truck traffic on I-35. This report summarizes the findings of research performed in the first three years and discusses the advantages and disadvantages of employing such a system with regard to the participation of both public and private sectors. Recommendations are then made for an innovative system that integrates the favorable aspects of this concept into the Texas Department of Transportation's plans for new statewide freight corridors.

This book was released on 2019 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing freight transportation capacity is the most important factor to keep US economy viable. Trucks moved 11.5 billion tons of goods, or 63.8 percent of total freight shipments in 2015, which is projected to grow to 16.6 billion tons by 2045. It is predicted truck travel may increase from 282 million miles per day in 2012 to 488 million miles per day by 2045. The U.S. railroad system includes 138,000 rail miles, which 93,500 miles owned and operated by Class I railroad and the rest of them owned and operated by regional and local railroads. While the miles of railroad are decreasing due to the poor condition of railroad and lower structural capacity of bridges, it is projected the annual tonnage of freight transportation by railroad increase by 24%. Existing and anticipated increases in the number of freight vehicles and other conveyances on both public and private infrastructure are stressing the system as more segments of the network approach or reach the capacity. The purpose of this dissertation is to estimate social and environmental benefits of three different alternatives, which are (1) widening the highway,(2) increase railroad capacity, and (3) implementation of underground freight transportation, to increase freight transportation capacity by using conceptual case study route. Underground Freight Transportation (UFT) is a class of automated inland freight transportation system, which vehicles carry freight through tunnels and pipelines between intermodal terminals. For this study, two traffic models, which are (1) Traffic Volume Distribution Model (TVDM) and (2) Traffic Flow Speed Prediction (TFSP) are developed.For estimating social and environmental cost of heavy-duty trucks, railroad, and UFT,following items are considered: (1) Air pollution, (2) Noise pollution, (3) Traffic accidents,and (4) Traffic congestion. Since the amount of emitted air pollution is dependent on the vehicle speed, new equations to estimate the social costs of air pollution are developed.As a result, UFT was found to have the lowest environmental and social costs compared with truck and railroad. UFT reduces air pollution, noise pollution, and traffic accidents reduce approximately 10%, 30%, and 30% respectively.

This book was released on 2016-03-15 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CIA’s 2013 release of its book The Central Intelligence Agency and Overhead Reconnaissance 1954–1974 is a fascinating and important historical document. It contains a significant amount of newly declassified material with respect to the U-2 and Oxcart programs, including names of pilots; codenames and cryptonyms; locations, funding, and cover arrangements; electronic countermeasures equipment; cooperation with foreign governments; and overflights of the Soviet Union, Cuba, China, and other countries. Originally published with a Secret/No Foreign Dissemination classification, this detailed study describes not only the program’s technological and bureaucratic aspects, but also its political and international context, including the difficult choices faced by President Eisenhower in authorizing overflights of the Soviet Union and the controversy surrounding the shoot down there of U-2 pilot Francis Gary Powers in 1960. The authors discuss the origins of the U-2, its top-secret testing, its specially designed high-altitude cameras and complex life-support systems, and even the possible use of poison capsules by its pilots, if captured. They call attention to the crucial importance of the U-2 in the gathering of strategic and tactical intelligence, as well as the controversies that the program unleashed. Finally, they discuss the CIA’s development of a successor to the U-2, the Oxcart, which became the world’s most technologically advanced aircraft. For the first time, the more complete 2013 release of this historical text is available in a professionally typeset format, supplemented with higher quality photographs that will bring alive these incredible aircraft and the story of their development and use by the CIA. This edition also includes a new preface by author Gregory W. Pedlow and a foreword by Chris Pocock.
