Book Description
Dans la présente thèse, nous modélisons l'évolution des trafics nationaux de voyageurs à longue distance, ferroviaires, aériens et autoroutiers, à l'aide de modèles macro-économiques calés sur séries temporelles. Les modèles calés sur séries temporelles offrent l'avantage de s'appuyer sur de l'information dynamique et permettent de mettre en évidence des relations de long terme entre les fluctuations de certaines variables et celles des trafics. Toutefois, ces modèles ne sont pas sans présenter des inconvénients. Ces modèles sont généralement des modèles de demande directe et perdent la logique de génération – partage modal. Par ailleurs, les variables explicatives sont généralement en nombre restreint et fortement agrégées, ce qui n'est pas sans soulever des problèmes de pertinence. Ainsi une même vitesse ferroviaire moyenne peut correspondre à des structures de temps de parcours différentes et donc à des impacts différents sur les trafics. Dans la présente thèse nous proposons un indicateur de vitesse ferroviaire qui permet d'intégrer des effets de structure et de seuils de concurrence air/fer. Nous testons par ailleurs différentes architectures, demande directe ou génération - partage modal. La thèse est divisée en 4 chapitres. Après avoir présenté les bases de données disponibles et décrit l'évolution des trafics, nous explicitons les principaux déterminants de la mobilité à longue distance puis effectuons une analyse bibliographique des différentes méthodes de modélisation existantes. Dans un dernier temps, nous construisons, et analysons sous l'angle de l'opérationnalité, différents modèles.

Book Description
Le problème de la modélisation de l'arbitrage du choix modal entre voiture particulière et transport collectif en milieu urbain peut paraître banal, mais il est toujours d'actualité et reste très délicat. L'existence des conditions objectives de l'augmentation du taux de motorisation de la population est indiscutable. La conséquence en est l'augmentation de la part de la population se trouvant devant le choix "voiture particulière - transports collectifs". La seule prise en considération des facteurs coût et temps de déplacement ne suffit pas à expliquer le comportement des individus dans certaines situations. C'est notamment vrai lorsqu'une bonne partie des usagers utilise l'automobile quand le temps de déplacement en voiture est égal ou supérieur au temps de déplacement en transports collectifs. Ce choix, surtout en milieu urbain, comprend une composante plus subjective que la valeur du temps : la composante psychologique. Une tentative de calculer l'influence de cette composante, ainsi que l'influence de la valeur du temps sur l'arbitrage "voiture particulière - transports en commun" est l'objectif principal de cette recherche. Le modèle est appliqué à la ville de Kharkov, Ukraine

Book Description
This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Book Description
This valuable volume offers a systematic approach to flight vehicle system identification and exhaustively covers the time domain methodology. It addresses in detail the theoretical and practical aspects of various parameter estimation methods, including those in the stochastic framework and focusing on nonlinear models, cost functions, optimization methods, and residual analysis. A pragmatic and balanced account of pros and cons in each case is provided. The book also presents data gathering and model validation, and covers both large-scale systems and high-fidelity modeling. Real world problems dealing with a variety of flight vehicle applications are addressed and solutions are provided. Examples encompass such problems as estimation of aerodynamics, stability, and control derivatives from flight data, flight path reconstruction, nonlinearities in control surface effectiveness, stall hysteresis, unstable aircraft, and other critical considerations.

Book Description
Acclaimed, when it first appeared, as a seminal work – a groundbreaking book that was both informative and highly readable – Translators through History is being released in a new edition, substantially revised and expanded by Judith Woodsworth. Translators have played a key role in intellectual exchange through the ages and across borders. This account of how they have contributed to the development of languages, the emergence of literatures, the dissemination of knowledge and the spread of values tells the story of world culture itself. Content has been updated, new elements introduced and recent directions in translation scholarship incorporated, providing fresh insights and a more nuanced view of past events. The bibliography contains over 100 new titles and illustrations have been refreshed and enhanced. An invaluable tool for students, scholars and professionals in the field of translation, the latest version of Translators through History remains a vital resource for researchers in other disciplines and a fascinating read for the wider public.

Book Description
This new edition of the seminal textbook The Economics of Urban Transportation incorporates the latest research affecting the design, implementation, pricing, and control of transport systems in towns and cities. The book offers an economic framework for understanding the societal impacts and policy implications of many factors including congestion, traffic safety, climate change, air quality, COVID-19, and newly important developments such as ride-hailing services, electric vehicles, and autonomous vehicles. Rigorous in approach and making use of real-world data and econometric techniques, the third edition features a new chapter on the special challenges of managing the energy that powers transportation systems. It provides fully updated coverage of well-known topics and a rigorous treatment of new ones. All of the basic topics needed to apply economics to urban transportation are included: Forecasting demand for transportation services under various conditions Measuring costs, including those incurred by users and incorporating two new tools to describe congestion in dense urban areas Setting prices under practical constraints Evaluating infrastructure investments Understanding how private and public sectors interact to provide services Written by three of the field’s leading researchers, The Economics of Urban Transportation is essential reading for students, researchers, and practicing professionals in transportation economics, planning, engineering, or related disciplines. With a focus on workable models that can be adapted to future needs, it provides tools for a rapidly changing world.
