National Transport Models: Recent Developments and Prospects (Advances in Spatial Science)

National Transport Models: Recent Developments and Prospects (Advances in Spatial Science) Review



National and European transport models become increasingly important. The broadening of national transport policy from strategic infrastructure investments to infrastructure management strengthens the need for advanced and more policy sensitive tools of analysis. The increase of interregional and international mobility requires forecasting tools that go beyond the urban or regional level. The competition for national infrastructure investments among regions and for Trans-European investments among nations has to be resolved by decisions and decision support systems at the appropriate spatial level. Environmental impacts transcend regional and national boundaries and transport policies affecting these environmental impacts involve all spatial levels. This volume presents the state of the art and prospects of a sample of the most advanced national and European transport models within a comparative framework.

Freight Forwarder's Intermediary Role in Multimodal Transport Chains: A Social Network Approach (Contributions to Management Science)

Freight Forwarder's Intermediary Role in Multimodal Transport Chains: A Social Network Approach (Contributions to Management Science) Review



In this book, the business of international freight forwarding is examined from both a theoretical and empirical point of view with a special emphasis on multimodal transport chains, including sea or air transport operations. In such contexts, the freight forwarder is always considered "The Architect of Transport", but this intermediary role seems to be largely neglected in research to date. Therefore, relevant concepts from economic theory and economic sociology are employed to produce both an intermediary and a network perspective of freight forwarding in order to provide a better understanding of this kind of transportation business. Furthermore, its intermediary role in such inherent network structures is explored by mapping relationship patterns in a stylized model framework applied to a questionnaire-based sample collected among freight forwarders engaged in such multimodal transport chains in Germany (especially from Hamburg, Bremen and Bremerhaven) as well as in Austria in 2003.

Transport cost analysis: a case study of the total costs of private and public transport in Auckland [An article from: Environmental Science and Policy]

Transport cost analysis: a case study of the total costs of private and public transport in Auckland [An article from: Environmental Science and Policy] Review



This digital document is a journal article from Environmental Science and Policy, published by Elsevier in . The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
The current level of motorised transportation worldwide is increasingly a social, environmental and economic problem. Transport benefits come alongside injuries and death, unproductive travel time, energy dependence, and environmental damage. One reason for the increasing problem results from externalising various impacts on society. Many of these external - or 'unpaid' - costs have only gradually been recognised and most have either been under-valued or are considered impossible to estimate since they have no value in a market. This research assesses the external (unpaid) and internal (user paid) cost of transport. It focuses on estimating the total cost of both private and public transport, using a case study for Auckland, New Zealand's largest city. The external costs are significant -2.23% of the GDP produced by the 1.2million Auckland region residents in 2001. Of this private transport generated 28 times more external cost than public transport. The internal cost assessment showed that total revenues collected did not even cover 50% of total transport cost. The research has shown that not only are the external costs of vehicle transport high, but that contrary to popular belief the total costs of private transport are subsidised by public transport users. This has implications for successful transport policy options.

Ionic Transport Processes: In Electrochemistry and Membrane Science

Ionic Transport Processes: In Electrochemistry and Membrane Science Review



Modelling of heterogeneous processes, such as electrochemical reactions, extraction or ion-exchange, usually requires solving the transport problem associated to the process. Since the processes at the phase boundary are described by scalar quantities and transport quantities are vectors or tensors, coupling of them can take place only via conservation of mass, charge or momentum. In this book, transport of ionic species is addressed in a versatile manner, emphasizing the mutual coupling of fluxes in particular. Treatment is based on the formalism of irreversible thermodynamics, i.e. on linear (ionic) phenomenological equations, from which the most frequently used Nernst-Planck equation is derived. Limitations and assumptions made are thoroughly discussed.

The Nernst-Planck equation is applied to selected problems at the electrodes and in membranes. Mathematical derivations are presented in detail so that the reader can learn the methodology of solving transport problems. Each chapter contains a large number of exercises, some of them more demanding than others.

Automotive Production Systems and Standardisation: From Ford to the Case of Mercedes-Benz (Contributions to Management Science)

Automotive Production Systems and Standardisation: From Ford to the Case of Mercedes-Benz (Contributions to Management Science) Review



The introduction of the Mercedes-Benz Production System (MPS) is exemplary of a trend within the automotive industry: the creation and introduction of company-specific standardised production systems. This book contributes to the debate about production systems by examining the social and economic implications of the role of standardisation in production systems. In this context it addresses three core issues: First, the driving forces behind the changing forms and functions of standardisation and the role of institutions therein. Second, the impact of standardisation on the evolution of automotive production systems. Third, based on the author's own empirical research conducted over a three year period at the Mercedes-Benz plant Stuttgart-Untertürkheim/Germany, the book examines the influence of standardisation on the work of actors on the shop floor in terms of organisational learning processes and the regulation of work.

Consumer-Oriented Business Design: The Case of Airport Management (Contributions to Management Science)

Consumer-Oriented Business Design: The Case of Airport Management (Contributions to Management Science) Review



Driven by rapidly changing business environments and more demanding consumers, many organizations are searching for new ways to achieve and retain a competitive advantage. In this context, new strategic frameworks and market research designs are needed that allow managers to synchronize the evolution of new offerings with changes in motivational patterns of consumers. This book presents a new strategic framework and the corresponding market research design which have already been tested successfully by a large empirical study at Munich airport. The framework has provided considerable input for new offering design and, therefore, the business redesign of organizations meeting future requirements of consumers.
