EVIDENCE IN TRAFFIC CRASH INVESTIGATION AND RECONSTRUCTION begins with a detailed description of the entire investigation process. The material then graduates into the various phases and levels of investigations, showing the levels of training and education normally associated with the levels of investigations and consequently the duties and responsibilities of the investigator and reconstructionist. Using narrative, schematics, and photographs, the mechanical inspection process is described in detail by identifying various vehicle parts, explanations of their functions, and methods of identifying failures. Human-related factors in traffic crash investigations are discussed at length, including the traffic crash viewed as a systems failure. Looming vulnerability, a recently developed theoretical construct that helps to describe and understand social, cognitive, organizational, and psychological mechanism, is described. Discussed also is the role of vision in driver performance; perception as a four-way process; perceptions and reactions; driver's reaction to stress; and the roles of pathologists, medical examiners, and coroners in traffic crash reconstruction. Who is an expert and expert evidence are described in detail. Errors that can occur in the investigation process and the tolerances that should be considered or allowed are explained. The manual also discusses the importance of calling upon the skills and advice of occupational specialists, such as reconstructionists, lawyers, traffic engineers, pathologists, medical examiners and others, to assist in the investigation and reconstruction of a crash that will ensure that the objectives of a thorough and complete investigation will be satisfied. Considerable effort has been made in the manual to explain how to identify, interpret and analyze all forms of highway marks and damages that can be used in the reconstruction of a vehicle-related crash. As a guide for investigators, prosecutors and defense attorneys, checkboxes are provided with many of the major topics that can be used as prompters in evaluating the thoroughness of an investigation or for those areas that might or might not need additional coverage at trial or litigation proceedings. To meet international requirements, mathematical references are described in both English (U.S.) and SI (metric) measurement systems, accompanied by various appendices covering symbols and mathematical conversions. Finally, there is a comprehensive quick-find index that takes the reader directly to any topic, formulae, or subject matter - or any combination of these.

This fully updated edition presents practices and principles applicable for the reconstruction of automobile and commercial truck crashes. Like the First Edition, it starts at the very beginning with fundamental principles, information sources, and data gathering and inspection techniques for accident scenes and vehicles. It goes on to show how to analyze photographs and crash test data. The book presents tire fundamentals and shows how to use them in spreadsheet-based reverse trajectory analysis. Such methods are also applied to reconstructing rollover crashes. Impacts with narrow fixed objects are discussed. Impact mechanics, structural dynamics, and conservation-based reconstruction methods are presented. The book contains a comprehensive treatment of crush energy and how to develop structural stiffness properties from crash test data. Computer simulations are reviewed and discussed. Extensively revised, this edition contains new material on side pole impacts. It has entirely new chapters devoted to low-speed impacts, downloading electronic data from vehicles, deriving structural stiffness in side impacts, and incorporating electronic data into accident reconstructions

The science of crash reconstruction enables engineers to determine the most probable scenario for how and why traffic collisions occur. Over the past 20 years, ongoing research has continually enhanced crash reconstructionists' knowledge of the application of physical laws in this field. Crash Reconstruction Research: 20 Years of Progress (1988-2007) features 47 papers that have presented significant steps forward, focusing on the following areas within the field of crash reconstruction that have experienced major advances: Planar Impact Mechanics, Stiffness Modeling, Crash Pulse Analysis, Structural Restitution, Lateral Deformation and Override/Underride, BEV v. Delta-V, Rear and Side Impacts, Pole Impacts, Uncertainty Analysis, Pedestrian Crashes, Braking Performance.

Automotive Accident Reconstruction: Practices and Principles introduces techniques for gathering information and interpreting evidence, and presents computer-based tools for analyzing crashes. This book provides theory, information and data sources, techniques of investigation, an interpretation of physical evidence, and practical tips for beginners. It also works as an ongoing reference for experienced reconstructionists. The book emphasizes three things: the theoretical foundation, the presentation of data sources, and the computer programs and spread sheets used to apply both theory and collected data in the reconstruction of actual crashes. It discusses the specific requirements of reconstructing rollover crashes, offers background in structural mechanics, and describes how structural mechanics and impact mechanics are applied to automobiles that crash. The text explores the treatment of crush energy when vehicles collide with each other and with fixed objects. It delves into various classes of crashes, and simulation models. The framework of the book starts backward in time, beginning with the analysis of post-crash vehicle motions that occurred without driver control. Applies time-reverse methods, in a detailed and rigorous way, to vehicle run-out trajectories, utilizing the available physical evidence Walks the reader through a collection of digital crash test data from public sources, with detailed instructions on how to process and filter the information Shows the reader how to build spread sheets detailing calculations involving crush energy and vehicle post-crash trajectory characteristics Contains a comprehensive treatment of crush energy This text can also serve as a resource for industry professionals, particularly with regard to the underlying physics.

Over the past 25 years, Harold and Darren Franck have investigated hundreds of accidents involving vehicles of almost every shape, size, and type imaginable. In Mathematical Methods for Accident Reconstruction: A Forensic Engineering Perspective, these seasoned experts demonstrate the application of mathematics to modeling accident reconstructions involving a range of moving vehicles, including automobiles, small and large trucks, bicycles, motorcycles, all-terrain vehicles, and construction equipment such as hoists and cranes. The book is anchored on basic principles of physics that may be applied to any of the above-named vehicles or equipment. Topics covered include the foundations of measurement, the various energy methods used in reconstruction, momentum methods, vehicle specifications, failure analysis, geometrical characteristics of highways, and softer scientific issues such as visibility, perception, and reaction. The authors examine the fundamental characteristics of different vehicles, discuss the retrieval of data from crash data recorders, and review low speed impacts with an analysis of staged collisions. Finally, the book details standards and protocols for accident reconstruction. Exploring a broad range of accident scenarios and also acknowledging the limits of applicability of the various physical methods employed, the breadth and depth of the book’s coverage makes it a critical reference for engineers and scientists who perform vehicular accident reconstructions.
