Traffic and Granular Flow '99 : Social, Traffic, and Granular Dynamics

"e;Are there common phenomena and laws in the dynamic behavior of granular materials, traffic, and socio-economic systems?"e; The answers given at the international workshop "e;Traffic and Granular Flow '99"e; are presented in this volume. From a physical standpoint, all these systems can be treated as (self)-driven many-particle systems with strong fluctuations, showing multistability, phase transitions, non-linear waves, etc. The great interest in these systems is due to several unexpected new discoveries and their practical relevance for solving some fundamental problems of today's societies. This includes intelligent measures for traffic flow optimization and methods from "e;econophysics"e; for stabilizing (stock) markets.
