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.

The purpose of this book is to bring to the student an understanding of the basic physics involved not only in traffic crash investigation and reconstruction but also in crimes or other incidents where the movement of objects or persons is involved. The range of topics included are those considered to be fundamental and which best serve the purposes of illustrating the methods and procedures vital as an introduction to physics. Essentials of the subject as related to vehicle motion are stressed. The mathematics used is kept simple and in straightforward, easy-to-understand language. Comments and examples and a very comprehensive list of terms and definitions, supported by many illustrations and diagrams, are provided to give the reader a unified view of basic physics. All materials are prepared in both the English (U.S.) and metric (S.I.) systems. The text is intended to serve a need for investigators who possess a good knowledge and understanding of elementary algebra and trigonometry, and who have successfully completed at least an at-scene traffic crash investigation course and wish to further their knowledge towards competency in advanced traffic crash investigation and reconstruction.

This expanded and updated third edition continues to be an essential reference volume in regards to the principles and techniques of traffic crash investigation. One of the most important phases of any investigation into a traffic crash is that which is conducted at the scene. The traffic crash investigator must be aware of his or her responsibilities and know how to properly fulfill them from the time of being advised of a crash to the time the report is completed based on the on-scene investigation. This manual sets out in detail the requisites for a properly conducted crash investigation by delineating the types of evidence to look for and how to recognize, interpret, gather, and record evidence such as skid marks, yaw marks, roadway and vehicle marks and damages, and environmental, human, and mechanical factors. Only by understanding the principles presented in the text will the objectives of a traffic crash investigation be met: what happened, where the crash occurred, why the crash occurred, and who was involved. The manual covers in both written and illustrative form those situations that confront the investigator conducting a technical crash investigation. An important introduction to scientific speed analysis based on thorough at-scene investigation is provided. Mathematical equations and examples are completed in both the United States or Imperial and metric (S.I.) measurement systems. The book is generously illustrated and substantial appendices provide helpful mathematical tables. This invaluable resource will meet the needs of law enforcement officers, insurance adjusters and investigators, private investigators, lawyers, judges, legal investigators, and instructors and students involved in cadet or advanced traffic crash investigation programs. This new edition will be appreciated by all those charged with the responsibility for investigating traffic crashes, interpreting data, and presenting evidence based on sound analysis.

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

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.
