Available in PDF, EPUB and Kindle. Book excerpt: Graphs. Most people identify this phrase with a statistical graph, such as a bar, line, circle or a graph of a function. But, the analysis of graphs is referred to as graph theory in mathematics. Graphs are a central topic in discrete mathematics. Graphs, which are comprised of vertices (nodes or actors) and edges (links), are used as models in graph theory. These mathematical models represent real-world problems and circumstances. The concept of graph theory is derived from a mathematical depiction of this type of situation. In mathematics, graph theory is an exciting and dynamic field. It is used to examine real-world challenges in various fields ranging from chemistry to linguistics, geography to sociology, transportation to infrastructure networks, social science to biological networks and so on. Graphs are mathematical constructions used to represent pair wise relationships between objects. They can be found on maps, in constellations and in the design and drafting process. Graphs highlight various computer applications that enable modem communication and technological processes. They serve to strengthen logical and abstract thinking. Graph theory emerged as an academic discipline in 1736, when Leonhard Euler solved the renowned Konigsberg bridge issue. Euler solved the Konigsberg bridge problem by expressing it as a graph theory problem, with the land areas represented as vertices and the bridges as edges. Euler introduced the concept of degree by stating that if a graph has no more than two odd vertices, then there exists some path that traverses each edge once. Complex network graphs differ greatly from ordinary graphs. Network science is the study of complex networks, which can represent any distinct system, from different interaction networks to social networks. Over the last two decades, network research has contributed to the identification of universal and surprising patterns in a wide range of domains, from ecological and social systems to technical and biological systems. From the research of last two decades in various domains, it will help to create innovative multidisciplinary tools for transforming many real world problems into models so that it can easily solvable.
Download or read book Centrality in Strategic Transportation Network Design written by Anne Lange and published by Springer. This book was released on 2019-03-01 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient and effective transportation networks are backbones to modern societies. Methodologically, their design has mainly been driven by optimization approaches oftentimes with a strong cost focus. Their strategic planning, however, should go beyond detailed cost analysis and identify other key decision drivers. Transportation network centrality describes the appearance of a network; hence is crucial for network design. Anne Paul develops a strategic approach to transportation network design by conceptualizing transportation network centrality and relating it to the performance and quality of transportation networks. Consequently, the concept of network centrality serves to support decisions in strategic network design. A practical implementation of this approach is provided, demonstrating its feasibility. Potential readers include scholars and practitioners from logistics, supply chain management, and operational research with an interest in strategic transportation network design.

Download or read book Transport Nodal System written by Adolf K.Y. Ng and published by Elsevier. This book was released on 2018-01-26 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport Nodal System provides a comprehensive introduction to the development of transport nodes and nodal systems, focusing on economic, operational, management, planning, policy, regulation and sustainability perspectives. Through a deep analysis on different types of transport nodes from diverse perspectives, this book shows the major issues and challenges that transport node planners, managers, and policymakers face, and how to address them. The book provides a clear framework for identifying the common attributes across all nodes that contribute to the efficient operations, planning, and management of transport facilities. Transport nodes such as seaports, inland terminals, airports, highways, and railroads are hubs in a multimodal transportation network that facilitate the smooth operation of passengers and freight. The book uniquely uses the transport node itself rather than a specific type of structure for a specific type of transport mode as the primary focus of analysis. While stressing the importance of transport nodes in developing efficient logistics and supply chains, the book also demonstrates that transport nodes are geographically embedded within a particular location, and that operations are inevitably affected by local factors, such as culture, the economy, the political and regulatory environment and other institutions. - Provides a unified look at multimodal transportation nodes to gain a better understanding of total system performance - Includes numerous case studies from developed and emerging economies - Uses an interdisciplinary approach where policy, regulations, economics, strategic management, operations, sustainability and technological innovation are considered together - Features chapters by scholars who specialize in different transport modes (land, sea and air) - Up-to-date outcomes utilizing author's original research provide a systematic investigation of the nodal system in both theory and practice

Download or read book Identifying the Critical Links in Road Transportation Networks written by and published by . This book was released on 2016 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface transportation road networks share structural properties similar to other complex networks (e.g., social networks, information networks, biological networks, and so on). This research investigates the structural properties of road networks for any possible correlation with the traffic characteristics such as link flows those determined independently. Additionally, we define a criticality index for the links of the road network that identifies the relative importance in the network. We tested our hypotheses with two sample road networks. Results show that, correlation exists between the link flows and centrality measures of a link of the road (dual graph approach is followed) and the criticality index is found to be effective for one test network to identify the vulnerable nodes.
Download or read book Optimal Transportation Networks written by Marc Bernot and published by Springer Science & Business Media. This book was released on 2009 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transportation problem can be formalized as the problem of finding the optimal way to transport a given measure into another with the same mass. In contrast to the Monge-Kantorovitch problem, recent approaches model the branched structure of such supply networks as minima of an energy functional whose essential feature is to favour wide roads. Such a branched structure is observable in ground transportation networks, in draining and irrigation systems, in electrical power supply systems and in natural counterparts such as blood vessels or the branches of trees. These lectures provide mathematical proof of several existence, structure and regularity properties empirically observed in transportation networks. The link with previous discrete physical models of irrigation and erosion models in geomorphology and with discrete telecommunication and transportation models is discussed. It will be mathematically proven that the majority fit in the simple model sketched in this volume.
Download or read book The Geography of Transport Systems written by Jean-Paul Rodrigue and published by Routledge. This book was released on 2013-07-18 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobility is fundamental to economic and social activities such as commuting, manufacturing, or supplying energy. Each movement has an origin, a potential set of intermediate locations, a destination, and a nature which is linked with geographical attributes. Transport systems composed of infrastructures, modes and terminals are so embedded in the socio-economic life of individuals, institutions and corporations that they are often invisible to the consumer. This is paradoxical as the perceived invisibility of transportation is derived from its efficiency. Understanding how mobility is linked with geography is main the purpose of this book. The third edition of The Geography of Transport Systems has been revised and updated to provide an overview of the spatial aspects of transportation. This text provides greater discussion of security, energy, green logistics, as well as new and updated case studies, a revised content structure, and new figures. Each chapter covers a specific conceptual dimension including networks, modes, terminals, freight transportation, urban transportation and environmental impacts. A final chapter contains core methodologies linked with transport geography such as accessibility, spatial interactions, graph theory and Geographic Information Systems for transportation (GIS-T). This book provides a comprehensive and accessible introduction to the field, with a broad overview of its concepts, methods, and areas of application. The accompanying website for this text contains a useful additional material, including digital maps, PowerPoint slides, databases, and links to further reading and websites. The website can be accessed at: http://people.hofstra.edu/geotrans This text is an essential resource for undergraduates studying transport geography, as well as those interest in economic and urban geography, transport planning and engineering.
