This book continues the biannual series of conference proceedings, which has become a classical reference resource in traffic and granular research alike. It addresses new developments at the interface between physics, engineering and computational science. Complex systems, where many simple agents, be they vehicles or particles, give rise to surprising and fascinating phenomena. The contributions collected in these proceedings cover several research fields, all of which deal with transport. Topics include highway, pedestrian and internet traffic, granular matter, biological transport, transport networks, data acquisition, data analysis and technological applications. Different perspectives, i.e. modeling, simulations, experiments and phenomenological observations, are considered.

This book continues the biannual series of conference proceedings, which has become a classical reference resource in traffic and granular research alike.

Complex systems, where many simple agents, be they vehicles or particles, give rise to surprising and fascinating phenomena.

Anyone who reflects on the future of society cannot do so without at the same time thinking about the future of our transportation systems. The dilemma is obvious. On the one hand, mobility must be maintained as it is crucial to economic development and because people are eager for individual mobility. On the other hand, traffic imposes heavy burdens on people and on the environment, on cities and communities and on our national economies. Finding a solution to that dilemma seems to be difficult, in fact we have not even developed a rough idea of how it could look like. This is why the North Rhine-Westphalia Science and Research Ministry came up with the plan to work out a well-founded scientific basis on which to solve the problems inherent in our transport system. A research network has been established and sponsored with government funds for a period of three years with a view to realising that objective. The "Traffic Simulation and Environmental Impact" research network is composed of researchers who have an excellent reputation as North Rhine-Westphalia traffic experts. Cutting across various disciplines of knowledge, the network aims to integrate transportation and natural sciences, particularly physics and mathematics, in a move to profit by the synergy between technical know-how and innovative methodology. The present volume is intended as a progress report and a prologue to the forthcoming international colloquium which represents the highlight and at the same time the end of the three-year project funding period.

Is the behaviour of a crowd in an emergency situation predictable? Are the different patterns occurring in pedestrian flow based on common rules? How does panic change human reactions? These and other questions have been the scope of the international conference on Pedestrian and Evacuation Dynamics. This book contains elaborate manuscripts written by scientists as well as practitioners from various disciplines: architecture, civil, naval and fire safety engineering, physics, computer science and mathematics. There has been considerable progress over the last decade and the central topic of human motion and behaviour has come more and more into the centre of interest, mainly due to increasing computer power and the development of new simulation models. This is the first conference dealing with modelling and simulation of pedestrian and crowd movement as well as the dynamical aspects of evacuation processes.

How do people behave in different traffic situations? Are there general laws for mathematical modelling of decision dynamics? The answers, given at the first international workshop on "Human Behaviour in Traffic Networks," are presented in this volume. In 13 articles, well-known experts report about their current work on experiments and modelling in this area. The topics range from psychological behaviour in traffic situations, traffic simulations of various aspects and market analysis to experiments with human participants used in experimental economics. The articles filled with many illustrations are aimed at interested students as well as experts in this field.

These proceedings are the fifth in the series Traffic and Granular Flow, and we hope they will be as useful a reference as their predecessors. Both the realistic modelling of granular media and traffic flow present important challenges at the borderline between physics and engineering, and enormous progress has been made since 1995, when this series started. Still the research on these topics is thriving, so that this book again contains many new results. Some highlights addressed at this conference were the influence of long range electric and magnetic forces and ambient fluids on granular media, new precise traffic measurements, and experiments on the complex decision making of drivers. No doubt the "hot topics" addressed in granular matter research have diverged from those in traffic since the days when the obvious analogies between traffic jams on highways and dissipative clustering in granular flow intrigued both c- munities alike. However, now just this diversity became a stimulating feature of the conference. Many of us feel that our joint interest in complex systems, where many simple agents, be it vehicles or particles, give rise to surprising and fascin- ing phenomena, is ample justification for bringing these communities together: Traffic and Granular Flow has fostered cooperation and friendship across the scientific disciplines.

Proper management of evacuation processes is one of the basic requirements within life safety concepts, and it helps to prevent critical situations from getting out of control. Super high-rise buildings, deep underground stations or shopping areas, airplanes for the mass transportation, sport stadiums or meeting places with tens of thousands of visitors-they all call for new dim- sionsinsafeevacuationplanning. Researchresultsinevacuationdynamicsgive answers to these challenges. PED-conferences are the prime address for all research in this ?eld. The increasing number of participants from di?erent ?elds of research re?ect theirimportance. AfterPED-conferencesinGermany(Duisburg,2001),Great Britain (Greenwich, 2003) and Austria (Vienna, 2005), the PED 2008 C- ference in Wuppertal/Germany reached new heights with more than 120 p- ticipants from 20 countries and nearly 100 presentations. The wide ?eld of topics discussed in presentations also re?ects deeper understanding of fun- mental e?ects as well as the stronger interactions between di?erent research areas. New test designs o?er new important basic data, new analysis pro- dures open a better understanding of complex interactions, new model - signs allow more realistic simulations, and the input from architectural - sign and the medical references on physical limitations help to realize a safe evacuation design. On the one hand all these data give an outlook of future possibilities and sometimes they open an astonishing new understanding of seemingly well-known data. On the other hand, they make clear the limi- tions of our current knowledge.

An overview of the recent progress of research in computational physics and materials science. Particular topics are modelling of traffic flow and complex multi-scale solidification phenomena. The sections introduce novel research results of experts from a considerable diversity of disciplines such as physics, mathematical and computational modelling, nonlinear dynamics, materials sciences, statistical mechanics and foundry technique. The book intends to create a comprehensive and coherent image of the current research status and illustrates new simulation results of transport and interface dynamics by high resolution graphics. Various possible perspectives are formulated for future activities. Special emphasis is laid on exchanging experiences concerning numerical tools and on the bridging of the scales as is necessary in a variety of scientific and engineering applications. An interesting possibility along this line was the coupling of different computational approaches leading to hybrid simulations.

The "Tra?c and Granular Flow '07" conference was the seventh of a series of international conferences that started in 1995 in Julic .. h (Germany). Since then, the conference took place in Duisburg (1997), Stuttgart (1999), Nagoya (2001), Delft (2003) and Berlin (2005). The aim of TGF conferences is to facilitate the exchanges between various ?elds dealing with transport. When the conference was created, the ?elds that were represented were road tra?c and granular ?ow - hence the name of the series. Since then, the scope of the conference has been enlarged to include in particular collective motion in biology (molecular motors), a subject which turns out to have many connections with the two original ones. Transversal themes have emerged. For TGF07, a session was speci?cally devoted to the subject of networks. An important theme is also the one of self-propelled particles. It ranges from granular ?ows with anisotropic grains, to collective motion of animals, and to pedestrian tra?c. We were very happy to organize the 2007 occurrence of TGF in Orsay (France), at the University Paris-Sud. The conference was organized mainly by the Laboratory of Theoretical Physics (LPT), with the help of the Labo- tory FAST (Fluides, Automatique et Syst' emes Thermiques) - these two la- ratories are both associated to the CNRS (Centre National pour la Recherche Scienti?que) - and of the GARIG Group at INRETS.
