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.

The last ten years have seen explosive growth in the technology available to the collision analyst, changing the way reconstruction is practiced in fundamental ways. The greatest technological advances for the crash reconstruction community have come in the realms of photogrammetry and digital media analysis. The widespread use of scanning technology has facilitated the implementation of powerful new tools to digitize forensic data, create 3D models and visualize and analyze crash vehicles and environments. The introduction of unmanned aerial systems and standardization of crash data recorders to the crash reconstruction community have enhanced the ability of a crash analyst to visualize and model the components of a crash reconstruction. Because of the technological changes occurring in the industry, many SAE papers have been written to address the validation and use of new tools for collision reconstruction. Collision Reconstruction Methodologies Volumes 1-12 bring together seminal SAE technical papers surrounding advancements in the crash reconstruction field. Topics featured in the series include: • Night Vision Study and Photogrammetry • Vehicle Event Data Recorders • Motorcycle, Heavy Vehicle, Bicycle and Pedestrian Accident Reconstruction The goal is to provide the latest technologies and methodologies being introduced into collision reconstruction - appealing to crash analysts, consultants and safety engineers alike.

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.

The analysis of a traffic accident requires additional knowledge that is not normally taught during the university education. Therefore, the analysis of road accidents usually is performed by specialized experts. The knowledge required for this was published in the early 80s in a previous German edition of this book. Now a team of authors created the long overdue update. The authors are experts in their field and make their knowledge available in a contemporary representation. In this computer-aided methods of work are taken into accountas as well. Content Accident survey - instrumentation - data for the calculation - kinematics - driving operation - kinetics - dynamics - information perception - speed calculation - collision mechanics - pedestrian - bicycle - cars - commercial vehicles - rollovers - rail based vehicles - biomechanics - occupant motion - simulation - animation Target groups Experts in accident reconstruction and damage assessment Traffic judges, prosecutors, lawyers Vehicle engineers Traffic police in training Insurance professionals in the claims settlement Insurance adjusters

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.

A journalist recounts the surprising history of accidents and reveals how they’ve come to define all that’s wrong with America. We hear it all the time: “Sorry, it was just an accident.” And we’ve been deeply conditioned to just accept that explanation and move on. But as Jessie Singer argues convincingly: There are no such things as accidents. The vast majority of mishaps are not random but predictable and preventable. Singer uncovers just how the term “accident” itself protects those in power and leaves the most vulnerable in harm’s way, preventing investigations, pushing off debts, blaming the victims, diluting anger, and even sparking empathy for the perpetrators. As the rate of accidental death skyrockets in America, the poor and people of color end up bearing the brunt of the violence and blame, while the powerful use the excuse of the “accident” to avoid consequences for their actions. Born of the death of her best friend, and the killer who insisted it was an accident, this book is a moving investigation of the sort of tragedies that are all too common, and all too commonly ignored. In this revelatory book, Singer tracks accidental death in America from turn of the century factories and coal mines to today’s urban highways, rural hospitals, and Superfund sites. Drawing connections between traffic accidents, accidental opioid overdoses, and accidental oil spills, Singer proves that what we call accidents are hardly random. Rather, who lives and dies by an accident in America is defined by money and power. She also presents a variety of actions we can take as individuals and as a society to stem the tide of “accidents”—saving lives and holding the guilty to account.
