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.

Essay from the year 2017 in the subject Law - Miscellaneous, grade: 0,0, Trinity College Dublin, course: International Aviation Law, language: English, abstract: When Paul Fauchille presented his dictum “[a]irspace should be free as the High Seas [...] States should only have the territorial powers up to an altitude of 300 metres." to the public in 1901, it did not take long until the international community disagreed strongly. The fear of espionage, attacks and other abuse was too great to give up sovereignty over the own territories’ airspace. This essay presents Fauchille’s idea of the freedom of the air (Chapter 2) and compares it with a concept of airspace sovereignty (Chapter 3), focussing on origin, arguments, logical consistency as well as international and national state practice. Further, it will be analysed whether current trends towards a liberalised market in scheduled international civil aviation could influence the legal status of the air (Chapter 4). Finally, remaining fields of strict sovereignty on the international political stage will be identified (Chapter 5), before a conclusion is drawn (Chapter 6). The legal status of the air was not questioned for a long time. The states’ inability to control the airspace and the circumstance that manned flights were not operated on a regular basis yet seems to have deterred states from any claims of sovereignty. However, the technological progress and the first short balloon flights in the late 18th century attracted the public’s attention. Among others, the French lawyer and pioneer of air law Paul Auguste Fauchille developed his own concept for the legal status of the air, which will be outlined in the next chapter.
