Book Description
"With international trade becoming a big part of the world's economic activity, the demand for good freight transportation systems has grown substantially. The appropriate use of transportation is an integral part of the supply chain's effectiveness. Therefore, the continuous economic globalization, the growing demand for speed-to-market product delivery, and the need to manage global supply chains more effectively, has led to the sustained increase in demand towards multimodal transportation systems (MTS). MTS play an essential role in corporations competing in global markets in the 21st century. In transportation, the effectiveness and efficiency of the whole system depends upon the interconnectivity of its elements. Because disruptions in the supply chain are costly, this research will look at improving the efficiency of MTS by looking at disruptions that have a negative impact on the elements that make up the system. Although past research classifies disruptions in MTS as: congestion, demand fluctuations, time delays, capacity limits, scheduling and, connectivity between the different modes, limited research address the relationship between these failures and the system. This research presents a Systems Dynamics (SD) approach to model MTS, which will let us iterate and mitigate a system to be able to forecast scenarios and meaningful hypothesis of a system's behavior over time. The SD model will aid to identify and understand those major elements and disruptions that altogether impact the efficiency of the MTS. The model will help determine how the disruptive factors of the supply chain are related to the efficiency of the system and will suggest decision-making strategies that will improve MTS performance over time being able to enhance customer satisfaction"--Abstract, page iii.

Book Description
The National Transportation System (NTS), an outgrowth of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), is proposed in this research as an analytical tool to guide national transportation policy making. The NTS must be based upon measures of transportation performance that are intermodal, user oriented, and suitable for tracking the environmental, social, and economic outcomes of transportation system use. A set of such performance measures is proposed, and implications of the measures for various modes are discussed. This proposal and discussion of performance measures is the critical component of this report. A major concern in the implementation of these performance measures is the data that supports them. A great deal of data is required to track the performance of the basic components of NTS analysis: major transportation facilities and regional transportation systems. Appropriate data sources for the NTS performance measures are identified, a sample of demonstration data is applied to the performance measures, and problems with data acquisition and application are discussed. A general framework for using the performance measures to achieve the NTS policy objective is proposed, and the implications of geographic information systems (GIS) and other technologies are discussed. Conclusions and recommendations from this research are presented.

Book Description
This report examines measures of effectiveness that can be used to compare the benefits and impacts of transportation improvements for a major investment study. A literature review was used to gather information about transportation performance measures and the social, economic and environmental effects of transportation. All metropolitan planning organizations within the state of Texas were surveyed to determine the state-of-the- practice for major investment studies within the state. A list of candidate measures of effectiveness for major investment studies was developed, and various judging criteria were used to qualitatively evaluate the measures. Preferred measures of effectiveness were identified that quantify the following benefits or impacts of transportation improvements: transportation performance, financial/economic performance, social impacts, land use/economic development impacts, and environmental impacts. Preferred transportation performance measures consisted mainly of person movement and travel time-based measures. Financial/economic performance measures centered around the cost effectiveness (benefit-to-cost ratio) and the financial feasibility, and considered the full costs (including externalities, or cost not borne by motorists) of transportation. Social, land use/economic development, and environmental impacts were identified, and coincided with those concerns most often expressed by citizen or community advocacy groups. Findings from the study illustrated the importance of matching the appropriate evaluation measures to the goals and objectives set forth early in the major investment study process.

Book Description
This primer provides a foundation for understanding the role of economic analysis in highway decision making. It is oriented toward state and local officials who have responsibility for assuring that limited resources get targeted to their best uses and who must publicly account for their decisions. Economic analysis is presented as an integral component of a comprehensive infrastructure management methodology that takes a long-term view of infrastructure performance and cost. The primer encompasses a full range of economic issues, including economic fundamentals, life-cycle cost analysis, benefit-cost analysis, forecasting traffic for benefit calculations, risk analysis and economic impact analysis.

Book Description
This progress report describes the development of the NTS initiative and proposed future activities to bring the NTS to its full potential. A set of preliminary national transportation performance indicators is proposed. These performance indicators should be seen as the beginning of a process rather than as the definitive set of national transportation system indicators. A second part of the NTS analytical process involves the development and application of a national transportation network analysis capability (NTNAC) that will provide the ability to evaluate the national network in a multi- modal manner. Using the NTNAC, problems with the Nation's transportation system can be identified and policy options to address these problems evaluated. The report concludes with a discussion of the use of the NTS within the Department. It is proposed that the results of the analyses carried out using the national transportation performance measures and the NTNAC in the assessment of the Nation's transportation system, the identification of issues, and the analysis of options be presented in biennial State of the National Transportation System reports.

Book Description
The objectives of this project were to review currently used methods of evaluating the economics of alternative transportation systems, develop a framework within which to evaluate the economics of alternative multimodal metropolitan transportation systems, and develop quantification methods for such factors as accessibility and capacity that relate them to all modes. The research was to include sensitivity analysis to identify those aspects of a modal investment policy that have major impacts on the output variables and therefore should be included in the results presented to transportation decision makers.

Book Description
This book is the result of a NATO Advanced Research Workshop which was held at Imperial College London in January 2009. It features contributions from a range of international experts covering topics related to the transport of hazardous materials, such as routeing and scheduling, risk assessment, security, and social and environmental exposure. There is also a broad look at the implications of climate change for transport. This unique resource offers a deep understanding of hazardous material transportation and concomitant security and environmental problems. The risks involved in the transport of dangerous goods are shown to arise mainly from the location of the sources and destinations as well as the timing of deliveries. Environmental concerns, including the implications of climate change for transport, provide a useful context for the more analytical material. The book is timely and topical as the subjects covered have become a focus for public concern in recent years, due in part to terrorist attacks on transport systems. This comprehensive reference provides examples from around the world, illustrating the diversity of regulations which apply to the handling and transport of dangerous goods. It also provides interesting insights into the global energy supply chain and describes on-going work on establishing network vulnerability.

Book Description
The performance of current transport systems is inadequate when viewed in terms of economic efficiency, sustainability and safety. Drawing together key an impressive list of contributors from the vast field of transportation economics including Kenneth Button, David Banister and Juan Carlos Martín, this book investigates transport systems, and covers a wide range of topics such as: airline markets congestion charging speed control. This informative book, ideal for undergraduate and postgraduate students of economics, business and industrial studies examines the tools that are necessary to effectively measure transport systems and those that are required to improve them. Utilizing advanced tools of network analysis, the contributors challenge various pieces of conventional wisdom, in particular the view that intermodal transport is more environmentally benign than road transport.
