Measuring Road Safety Using Surrogate Events provides researchers and practitioners with the tools they need to quickly and effectively measure traffic safety. As traditional crash-based safety analyses are being undermined by today's growing use of intelligent vehicular and road safety technologies, crash surrogates--or near misses--can be more effectively used to measure the future risk of crashes. This book advances the idea of using these near-crash techniques to deliver quicker and more adequate measurements of safety. It explores the relationships between traffic conflicts and crashes using an extrapolation of observed events rather than post-crash data, which is significantly slower to obtain. Readers will find sound estimation methods based on rigorous scientific principles, offering compelling new tools to better equip researchers to understand road safety and its factors.
This collection is dedicated to the 70th jubilee of Yu. N.
Savchenko, and presents experimental, theoretical, and numerical
investigations written by an international group of well-known
authors. The contributions solve very important problems of the
high-speed hydrodynamics, such as supersonic motion in water, drag
diminishing, dynamics and stability of supercavitating vehicles,
water entry and hydrodynamic performances of hydrofoils, ventilated
cavities after a disc and under the ship bottom.
The book covers the various approaches to modeling the in-cylinder processes such as mixture formation, combustion and formation of exhaust emissions in diesel and gasoline engines. Due to their complexity, emphasis is put on multi-dimensional spray, combustion and emission formation models. However, phenomenological as well as zero-dimensional thermodynamic models, which are still widely used in engine development because of their computational efficiency, are addressed as well. Example calculations of each model type are compared with corresponding experimental data – represented in diagrams as well as in images resulting from modern optical measuring techniques – in order to discuss the capabilities of today's simulation models and the shortcomings that still exist either because of oversimplifying assumptions or insufficient knowledge. Readers achieve an overview of the most important simulation models describing the in-cylinder processes of internal combustion engines and gain insights into which modeling approach is appropriate for a specific problem.

This book elaborates the science and engineering basis for energy-efficient driving in conventional and autonomous cars. After covering the physics of energy-efficient motion in conventional, hybrid, and electric powertrains, the book chiefly focuses on the energy-saving potential of connected and automated vehicles. It reveals how being connected to other vehicles and the infrastructure enables the anticipation of upcoming driving-relevant factors, e.g. hills, curves, slow traffic, state of traffic signals, and movements of nearby vehicles. In turn, automation allows vehicles to adjust their motion more precisely in anticipation of upcoming events, and to save energy. Lastly, the energy-efficient motion of connected and automated vehicles could have a harmonizing effect on mixed traffic, leading to additional energy savings for neighboring vehicles. Building on classical methods of powertrain modeling, optimization, and optimal control, the book further develops the theory of energy-efficient driving. In addition, it presents numerous theoretical and applied case studies that highlight the real-world implications of the theory developed. The book is chiefly intended for undergraduate and graduate engineering students and industry practitioners with a background in mechanical, electrical, or automotive engineering, computer science or robotics.

Rycroft, CAESAR Consultancy, 35 Millington Road, Cambridge CB3 9HW, UK e-mail: Michael. J. Rycroft (R)ukgateway. net As Symposium Committee Chair for the 2003 International Space University (ISU) Symposium, and Editor of this Proceedings volume, respectively, we write this introduction. The success of previous ISU symposia suggests that the ISU has developed a unique and winning formula for a novel type of symposium. The characteristics of ISU symposia are that they: * Adopt a broad, and interdisciplinary, perspective * Address all aspects of the subject, ranging from policy, business, organisational, and legal issues to technical and scientific topics * Foster a constructive dialogue among very different sectors of the space community, and * Allow ample time for interactive discussions. The present Symposium is no exception. It considers the very timely topic of space-based systems for global positioning and navigation, ranging from the GPS system developed by the US military to the Russian GLONASS system, and on to the future European Galileo system. Other nations are planning regional augmentation systems.
The history of gears with asymmetric teeth is not sufficiently recorded in modern gear literature, with some gear researchers concluding that asymmetric tooth gears were discovered just several decades ago. This book sheds light upon the origins and state of asymmetric gearing, referencing technical articles from the 19th, 20th, and 21st centuries. As a practicing gear engineer with over 40 years' experience, author Alexander L. Kapelevich has successfully implemented asymmetric gears in a variety of custom gear transmissions. This book addresses all aspects of asymmetric gear development, including theoretical fundamentals; tooth geometry optimization; stress analysis and rating; design and production specifics; analytical and experimental comparison to the best symmetric gears; and application examples. Readers are encouraged to look beyond the status quo established by traditional gear design, and to apply principles of asymmetric gearing to actual gear design. Optimal solutions are presented for gear drives that will maximize technical performance and marketability. Features Presents a state-of the-art, comprehensive historical overview of asymmetric gearing Explains the Direct Gear Design (R) approach to asymmetric gear design Describes asymmetric tooth gear geometry optimization, areas of existence, and parameter selection limits Considers practical aspects of asymmetric gear fabrication and measurement Presents analytical and experimental comparison of asymmetric gears to advanced symmetric gears, showing the advantages of asymmetric designs Provides numerous real-world examples of asymmetric gear application
The IFAC Workshop on Intelligent Components for Vehicles (ICV'98) was held in Seville (Spain), on March 23-24 1998. The event follows the Workshop on Intelligent Components for Autonomous and Semiautonomous Vehicles (ICASAV'95) held in Toulouse (France, October 1995). The main objective of ICV'98 was to bring together specialists on components and instruments for automotive systems, mobile robots and vehicles in general to enhance the value of their experience in both hardware and software intelligent components. Future vehicles will deal more and more with autonomous functions to improve safety and traffic management and to reduce consumption and pollution. Numerous on-board decision systems will replace the driver in critical running phases. The problems and solutions experienced, by adopting this new technology, will bring out many common points with other transportation systems and mobile robots. Research and Developments on Mobile Robotics have produced many components for perception, control and planning that can be used in vehicles for collision detection and avoidance, position estimation, guidance and manoeuvering aids for drivers, advanced teleoperation, and other applications. The topics of the Workshop are in an emerging field in which the research is quickly being converted into industrial products. Several applications in the automotive domain, marine vehicles, agricultural and others were included in the program. In addition to the presentation of the papers, ICV also included
a plenary talk and a round table about intelligent components for
future vehicles with the participation of several industrial
companies.
Humans and space When faced with the issue of space exploration, one generally has an idea of the ?elds of study and disciplines that are involved: technology, physics and chemistry, robotics, astronomy and planetary science, space biology and medicine, disciplines which are usually referred to as the ?sciences?. In recent discussions, the human element of space exploration has attracted more and more the interest of the space sciences. As a consequence, adjacent disciplines have gained in relevance in space exploration and space research, in times when human space ?ights are almost part of everyday life. These disciplines include psychology and sociology, but also history, philosophy, anthropology, cultural studies, political sciences and law. The cont- bution of knowledge in these ?elds plays an important role in achieving the next generation of space exploration, where humans will resume exploring the Moon and, eventually, Mars, and wherespacetourism isbeginningtobedeveloped. With regard to technology, one might soon be prepared for this. Much less is this the case with space exploration by humans, rather than by robots. Robotic explorations to other planets across the solar system have developed in the past 50 years, since the beginning of the ?space age? with the presence of humans in nearby space and the landing on the Moon. Space exploration is now not only focused on technological achievements, asitsdevelopmentalsohassocial, culturalandeconomicimpacts. This makes human space exploration a topic to address in a cross-disciplinary mann

This book provides an introduction to the Human Centred Design of autonomous vehicles for professionals and students. While rapid progress is being made in the field of autonomous road vehicles the majority of actions and the research address the technical challenges, with little attention to the physical, perceptual, cognitive and emotional needs of humans. This book fills a gap in the knowledge by providing an easily understandable introduction to the needs and desires of people in relation to autonomous vehicles. The book is "human centred design" led, adding an important human perspective to the primarily technology-driven debates about autonomous vehicles. It combines knowledge from fields ranging from linguistics to electrical engineering to provide a holistic, multidisciplinary overview of the issues affecting the interactions between autonomous vehicles and people. It emphasises the constraints and requirements that a human centred perspective necessitates, giving balanced information about the potential conflicts between technical and human factors. The book provides a helpful introduction to the field of design ethics, to enhance the reader's awareness and understanding of the multiple ethical issues involved in autonomous vehicle design. Written as an accessible guide for design practitioners and students, this will be a key read for those interested in the psychological, sociological and ethical factors involved in automotive design, human centred design, industrial design and technology.
