Motorcycle Accident Reconstruction


Book Description

Accident reconstruction utilizes principles of physics and empirical data to analyze the physical, electronic, video, audio, and testimonial evidence from a crash, to determine how and why the crash occurred, how the crash could have been avoided, or to determine whose description of the crash is most accurate. This process draws together aspects of mathematics, physics, engineering, materials science, human factors, and psychology, and combines analytical models with empirical test data. Different types of crashes produce different types of evidence and call for different analysis methods. Still, the basic philosophical approach of the reconstructionist is the same from crash type to crash type, as are the physical principles that are brought to bear on the analysis. This book covers a basic approach to accident reconstruction, including the underlying physical principles that are used, then details how this approach and the principles are applied when reconstructing motorcycle crashes. This second edition of Motorcycle Accident Reconstruction presents a thorough, systematic, and scientific overview of the available methods for reconstructing motorcycle crashes. This new edition contains: Additional theoretical models, examples, case studies, and test data. An updated bibliography incorporating the newest studies in the field. Expanded coverage of the braking capabilities of motorcyclists. Updated, refined, and expanded discussion of the decelerations of motorcycles sliding on the ground. A thoroughly rewritten and expanded discussion of motorcycle impacts with passenger vehicles. Updated coefficients of restitution for collisions between motorcycles and cars. A new and expanded discussion of using passenger car EDR data in motorcycle accident reconstruction. A new section covering recently published research on post-collision frozen speedometer readings on motorcycles. A new section on motorcycle interactions with potholes, roadway deterioration, and debris and expanded coverage of motorcycle falls. This second edition of Motorcycle Accident Reconstruction is a must-have title for accident reconstructionists, forensic engineers, and all interested in understanding why and how motorcycle crashes occur.




Bicycle Accident Reconstruction for the Forensic Engineer


Book Description

Bicycle Accident Reconstruction for the Forensic Engineer describes the methodology for reconstructing bicycle and pedestrian accidents. Of particular interest is analysis of light, signation and conspicuity on the reconstruction of all types of accidents.




Vehicular Accident Investigation and Reconstruction


Book Description

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.







Automotive Accident Reconstruction


Book Description

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.




Mathematical Methods for Accident Reconstruction


Book Description

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




The Accident of Color: A Story of Race in Reconstruction


Book Description

A technicolor history of the first civil rights movement and its collapse into black and white. Brutal slavery existed all over the New World, but only America followed emancipation with a twisted system of segregation. The Accident of Color asks why. Searching for answers, Daniel Brook journeys to the places that resisted Jim Crow the longest. In the cosmopolitan port cities of New Orleans and Charleston, integrated streetcars plied avenues patrolled by integrated police forces for decades after the Civil War. This progress was ushered in during Reconstruction when long-free, openly biracial communities joined in coalition with the formerly enslaved and allies at the fringes of whiteness. Tragically, their victories—including integrated schools—and their alliance itself were violently uprooted by segregation along a stark, new black-white color line. By revisiting a turning point in the construction of America’s uniquely restrictive racial system, The Accident of Color brings to life a moment from our past that illuminates the origins of the racial lies we live by.







FORENSIC ENGINEERING RECONSTRUCTION OF ACCIDENTS


Book Description

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.
