Accident investigation/reconstruction is more than just a job or even a profession; it is more art than science and requires a dedication greater than a commitment of time. It takes constant reading, study, and analysis of accident information and case reconstructions to keep improving your performance, both in the field and in the courtroom. Vehicular Accident Investigation and Reconstruction concentrates on the development of the skills, education, and information needed for an accident investigation and reconstruction, including the necessary tools, some of the pitfalls facing the investigator/reconstructionist and the latest advances and techniques in the field. The book is divided into four sections: Section 1 -- Describes the need for proper accident investigation, the specialized tools, education, and the necessary mindset Section 2 -- Deals with reconstruction, which requires deductive reasoning, logic, physics, engineering, and a general knowledge of the accident subject Section 3 -- Discusses occupant kinematics or body movement and reaction to external forces, including human anatomy, physiology, human tolerance to impact, and occupant reactions to various types of impacts Section 4 -- Discusses latest techniques for investigation and reconstruction, citing examples such as electronic scene mapping, computer animation, computer accident simulation, and the use of the computer in the courtroom.

Is it safe to drive with these large trucks? What happens when the small car in front of the commercial vehicle slams on its brakes? Reconstructing commercial vehicle accidents is a complex task that is often misunderstood or misinterpreted. Frequently, mistakes are made in determining the vehicle's ability to brake efficiently, the engine speeds and the loading condition. This reference book identifies the proper techniques you should use in order to correctly assess a commercial vehicle accident scene.The authors of this text discuss in great detail the unique aspects of commercial vehicle operation, performance and regulations. Chapters are dedicated to the various operating systems of these vehicles such as the electrical systems, tires, steering, suspension and much more. You will also learn about the human factors in commercial vehicle operations and accidents. The drivers of these trucks must drive at 100 percent of their ability in all situations and must meet certain requirements before they are allowed behind the wheel. Even so, accidents do occur and are sometimes caused by the driver's response.New to this expanded second edition are chapters on vehicle headlamps, terminology, Automatic On-Board Recording Devices (AOBRD), wireless communications equipment, collision warning systems and smart cruise, vehicle speed sensor, and testimony questions, among others.If you are interested in reconstructing or investigating commercial vehicle accidents, or if you are already involved in this but would like a better understanding of the issues, this book will prove to be valuable tool.

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.

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.

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.

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.
