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 volume deals with 17 major issues arising from traffic accident reconstruction. The product of numerous individuals experienced in accident reconstruction, the manual is geared toward data interpretation and directed toward engineers and people with technical backgrounds. The manual relies heavily on mathematics to interpret how an accident occurred, as is consistent with the progression from data collection to reconstruction. Real world accident cases are used to illustrate each topic whenever possible. Beginning with an overview of the process of traffic accident reconstruction, the manual discusses causes and contributing factors in traffic accidents; mathematics and physics used in traffic accident reconstruction, basic motion equations; understanding vehicle behavior in collisions; drag factor and coefficient of friction; perception and reaction in traffic accidents; speed estimates for vehicles that fall, flip, or vault; momentum applications; work, energy, and speed from damage in traffic accidents; steering overcorrection in traffic accidents; reconstruction of motorcycle traffic accidents; understanding occupant behavior in vehicle collisions; vehicle-pedestrian accident reconstruction; reconstruction of heavy truck accidents; derivations of equations; and the use of computers in traffic accident reconstruction.

In this third edition of Vehicle Accident Analysis & Reconstruction Methods, Raymond M. Brach and R. Matthew Brach have expanded and updated their essential work for professionals in the field of accident reconstruction. Most accidents can be reconstructed effectively using of calculations and investigative and experimental data: the authors present the latest scientific, engineering, and mathematical reconstruction methods, providing a firm scientific foundation for practitioners. Accidents that cannot be reconstructed using the methods in this book are rare. In recent decades, the field of crash reconstruction has been transformed through the use of technology. The advent of event data records (EDRs) on vehicles signaled the era of modern crash reconstruction, which utilizes the same physical evidence that was previously available as well as electronic data that are measured/captured before, during, and after the collision. There is increased demand for more professional and accurate reconstruction as more crash data is available from vehicle sensors. The third edition of this essential work includes a new chapter on the use of EDRs as well as examples using EDR data in accident reconstruction. Early chapters feature foundational material that is necessary for the understanding of vehicle collisions and vehicle motion; later chapters present applications of the methods and include example reconstructions. As a result, Vehicle Accident Analysis & Reconstruction Methods remains the definitive resource in accident reconstruction.

As a traffic accident investigator or reconstructionist, you probably have the common speed and sliding formulas memorized. However, there likely are formulas out there that you haven't committed to memory. And, while it's not practical to carry around a large textbook to every accident scene, having some type of reference would make your job easier. That is why the Pocket Traffic Accident Reconstruction Guide was created.Timothy Stabb, the author, created the Pocket Traffic Accident Reconstruction Guide to be an easy to use reference for anyone investigating a traffic accident. The guide is a pocket-sized booklet containing over eighty equations to compute vehicle velocity/speeds, distance, time acceleration rates and more. Designed to fit in a shirt pocket, day planner or briefcase, this handy guide also contains a glossary of traffic collision terms, a list of helpful websites, a table of roadway friction coefficient values and a conversion multiplier.It contains equations for:Converting speed from MPH to FPS, Converting velocity from FPS to MPH, Airborne projectile motion, Center of gravity mass, Pedestrian impact, And many more.

This handbook is prepared for the daily, practical needs of those who are involved in traffic accident analysis, investigation, and reconstruction, whether they be in the training, police, private, or legal professions. It also meets international requirements in that all formulae and explanations are provided in both the English (U.S.) and metric (S.I.) measurement systems. In all cases, the two systems are dealt with separately so as to avoid any unnecessary confusion. Provided also are many tables and constants relating one system to the other so that those who may normally work under one system but use reference materials in the other will have a readily accessible means of making any necessary conversions. After an introductory chapter describes the various symbols used in traffic accident investigation and reconstruction, subsequent chapters include very comprehensive formulae required in problem-solving involving acceleration and acceleration factors; center of mass; drag factor and coefficient of friction; slide-to-stop speed; yaw, sideslip, or critical curve speeds; acceleration, distance and time calculations; momentum speed; combined speeds, and distance and time calculations. Additionally, there are various other formulae and mathematical, velocity, and conversion tables presented. All 160 formulae and their various uses are set out in a uniform, easy-to-read, and understandable format. Whether in law, law enforcement, or private or insurance investigation, this book provides traffic accident investigators and reconstructionists with the data they need to perform their job accurately and efficiently.

This book is not an advanced engineering text. Rather, it is a practical presentation with traffic accident reconstruction principles presented in a simple, understandable manner so that the reader will easily retain these important concepts. The engineering principles involved are introduced at the elementary level, and in many cases equations used in freshman physics are derived. The authors believe that the derivations are presented in the simplest manner possible so that the reader will retain this material. The book is the result of an effort to compile over a period of years useful forensic engineering data, information, and analytical techniques over and above those taught to non-engineers. Many of the mathematical treatments are original. In general, the book reflects the authors' combined over forty years experience of forensic investigations involving thousands of cases. It offers something for everyone interested in forensic engineering. In the new second edition, Chapters 3 to 5 have been substantially modified, and the remainder of the text has been edited to bring its various parts up to date. The experienced investigator will find a wealth of new ideas and relationships to fill in gaps in his knowledge and reinforce his analytical approaches. Those starting new in this work will have an advantage on their competition after studying this material. For the non-technical reader, most of the book is eminently readable. To an investigator, attorney, or insurance adjuster with only a nodding acquaintance with freshman physics, the book should be totally comprehensible.
