This in-depth treatment explains the nature of traffic breakdown and the resulting congestion in vehicular traffic on the basis of three-phase traffic theory, in a manner consistent with real measured traffic data. The author also addresses freeway traffic control methods within the framework of the theory. He demonstrates and explains why the earlier theoretical basis of transportation engineering, research and teaching cannot adequately describe traffic breakdown as observed in measured traffic data. Links between three-phase traffic theory and earlier traffic flow theories are discussed. Last but not least, the book provides a new fundament for transportation engineering, in particular highway traffic management, as well as the background needed to research the complex system dynamics in traffic flow and transportation networks. It will appeal to students, engineers, and physicists interested in transportation systems and complex dynamical systems in general.

By Per Freiesleben Hansen
Publisher: Springer | 2009 | 400 Pages | ISBN: 3540708979 | PDF | 11.78 MB
The Science of Construction Materials is a study and work book for civil engineering students. Since the contents of the book are presented in a way that makes the reading an active process, the book is also suitable as self-study for the researcher and practising civil engineer. The publication is not a textbook on thermodynamics, but rather an incentive to use the calculation methods of physical chemistry to solve problems within the science of construction materials. The presentation of the theoretical subjects is supported by approximately 500 exercises with solutions as well as commented examples of calculations; throughout the book the relation to civil engineering practice is demonstrated. A detailed subject index and a comprehensive collection of tables of physical and chemical data for substances relevant for the science of construction materials are also found in the book. This makes the book suitable as a work of reference.

There are enlightened basic aspects of scientific concrete science. There is given summary of modern ideas about hardening and structure-forming of cement stone and concrete, rheological and technological properties of concrete mixtures, strength, strain and other properties, which determine concrete operate reliability and durability. There are considered basic types of normal weight cement concrete, lightweight and cellular concrete, non-cement mineral binders concrete, mortars.
