During the last decade physicists, engineers and computer scientists have joined in an enormously fruitful dialogue about traffic and granular flow. Cars and sand grains have in common, that they interact irreversibly, which is the reason for similar jamming phenomena. The main difference is that car drivers choose their destination and route individually, while grains follow external driving forces. This book gives an overview about the progress in modelling, computer simulation, experiments and field observations, which was reached within the last two years. The contributions are based on the International Workshop Traffic and Granular Flow '01, which took place in Nagoya, 15 - 17 October 2001. Topics include a critical classification of models for highway traffic, new technological applications, friction and arching phenomena in pedestrian traffic, scale free networks and internet traffic, instabilities and fluctuations in avalanches and granular pipe flow.

The Conference on Traffic and Granular Flow brings together international researchers from different fields ranging from physics to computer science and engineering to discuss the latest developments in traffic-related systems. Originally conceived to facilitate new ideas by considering the similarities of traffic and granular flow, TGF'15, organised by Delft University of Technology, now covers a broad range of topics related to driven particle and transport systems. Besides the classical topics of granular flow and highway traffic, its scope includes data transport (Internet traffic), pedestrian and evacuation dynamics, intercellular transport, swarm behaviour and the collective dynamics of other biological systems. Recent advances in modelling, computer simulation and phenomenology are presented, and prospects for applications, for example to traffic control, are discussed. The conference explores the interrelations between the above-mentioned fields and offers the opportunity to stimulate interdisciplinary research, exchange ideas, and meet many experts in these areas of research.

Verkehrsdynamik präsentiert die neuesten Entwicklungen im Bereich Modellierung und Simulation des Fußgänger- und Autobahnverkehrs, basierend auf einer Synthese physikalischer und sozialwissenschaftlicher Konzepte. Im Zentrum des Interesses steht der Vergleich der Modelle mit empirischen Daten sowie das Verständnis von "Staus aus dem Nichts" und anderen faszinierenden kollektiven Bewegungsmustern, die durch Selbstorganisation entstehen. Verkehrsdynamik diskutiert neuartige Methoden, wie Selbstorganisationsphänomene zur Optimierung des Verkehrsflusses ausgenutzt werden können und wendet sich an Wissenschaftler, Städte- und Verkehrsplaner. Die behandelte Thematik genießt wegen ihrer aktuellen gesellschaftlichen und politischen Relevanz in jüngster Vergangenheit eine außerordentlich große Aufmerksamkeit in den Medien.

Can one obtain new insights by comparing the motion of bacteria or plankton striving for food & light with that of pedestrians in a crowded street? Do complex transport networks behave similarly under high load, be it the internet or downtown city traffic? These & related questions were topics of the international workshop on Traffic & Granular Flow '97, which took place in Duisburg, 6-8 October, 1997 (as part of the 25th anniversary of the Gerhard-Mercator-Universitat, Duisburg). The contributions contained in the book reflect the enormous research activities in this interdisciplinary field which attracts increasing public attention.

Doktorarbeit / Dissertation aus dem Jahr 2003 im Fachbereich Verkehrswissenschaft, Universität Duisburg-Essen, Sprache: Deutsch, Abstract: The movement of crowds is a field of research that attracts increasing interest. This is due to three major reasons: pattern formation and selforganization processes that occur in crowd dynamics, the advancement of simulation techniques and hardware that enable fast and realistic simulations, and finally the growing area of potential applications (planning of pedestrian facilities, crowd management, or evacuation analysis). The field is spanning the borders of various disciplines: physiology, psychology, sociology, civil engineering, mathematics, physics, etc. It depends on the point of view which aspects are given the main focus. One approach is to reduce complexity to fundamental principles that make a mathematical (quantitative) formulation possible and at the same time are sufficiently complex to reproduce the major phenomena that can be observed in reality. The major aim of this dissertation is to define and validate a model for the simulation of evacuation processes and their analysis. To this end the analogy between non-equilibrium many particle systems and crowds is used. However, it will also become clear that this analogy is not sufficient for complex scenarios and realistic egress simulations and additional, ‘non-physical’, parameters and principles must be introduced. Even though the investigation is motivated by the applications, the dynamics of crowd movement and model properties are scrutinized. This also includes a thorough review of the data available in the literature, the calibration of the model parameters and the comparison of simulated and empirical flow-density relations. The core of any evacuation simulation is a set of rules or equations for the movement of people. This is connected to the representation of space, population, and behavior. These topics will be investigated generally (micro- vs. macroscopic, discrete vs. continuous) and especially with regard to a specific two-dimensional cellular automaton model, where the movement dynamics is based on discrete space and time. This allows an efficient implementation and therefore large scale simulations. The route-choice is done via the orientation along a discrete vector field which can in principal be derived from a discrete potential. It is therefore not explicitly simulated but taken into account in a pre-determined way, i.e., the coupling to the vector field is static (constant coupling parameter).

Dry granular materials, such as sand, sugar and powders, can be poured into a container like a liquid and can also form a pile, resisting gravity like a solid, which is why they can be regarded as a fourth state of matter, neither solid nor liquid. This book focuses on defining the physics of dry granular media in a systematic way, providing a collection of articles written by recognised experts. The physics of this field is new and full of challenges, but many questions (such as kinetic theories, plasticity, continuum and discrete modelling) also require the strong participation of mechanical and chemical engineers, soil mechanists, geologists and astrophysicists. The book gathers into a single volume the relevant concepts from all these disciplines, enabling the reader to gain a rapid understanding of the foundations, as well as the open questions, of the physics of granular materials. The contributors have been chosen particularly for their ability to explain new concepts, making the book attractive to students or researchers contemplating a foray into the field. The breadth of the treatment, on the other hand, makes the book a useful reference for scientists who are already experienced in the subject.

Die Ausspähprogramme Prism und Tempora, die durch den Whistleblower Edward Snowden bekannt wurden, sind nur die Spitze des Datenbergs. Auskunfteien, Internetunternehmen und Einzelhandelsketten sammeln schon seit Jahren Informationen über die Bürger. Möglich wird all das durch Big Data, also die Möglichkeit, ungeahnte Mengen an Daten zu erheben, zu speichern und zu analysieren. Big Data, darin sind sich Analysten und Wissenschaftler einig, könnte die Art und Weise, wie wir Entscheidungen treffen, konsumieren, forschen und leben dramatisch verändern. Manche fühlen sich dabei an George Orwells 1984 erinnert, anderen sehen darin eine digitale Glaskugel, die gigantische Wachstumschancen bietet und neue Forschungswelten eröffnet. Der Band bietet einen Überblick über die vielfältigen Anwendungsbereiche und Akteure, renommierte Praktiker, Soziologen und Technikexperten beleuchten das Thema Big Data aus unterschiedlichen Perspektiven. Mit Beiträgen von Chris Anderson (The Long Tail), Dirk Baecker, Peter Glaser, Michael Hagner und Dirk Helbing, Bruno Latour, Frank Schirrmacher und vielen anderen.
