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 book's title has two parts, "Roadway Human Factors" and "From Science To Application." The first describes its major goal: to analyze driver behavior, especially the causes and avoidance of collisions. In most general terms, the goal is largely to answer a single question: "Why didn't the driver respond sooner?" The cause of most collisions lies in the answer. The book's perspective is psychological. It views roadway events through the eyes of the driver. This contrasts with the third-party god's eye view that appears in accident reconstruction diagrams and other analyses which are primarily based in physics and cookbook science. Physics cannot be ignored, but roadway events can only be explained by examining driver psychology. Drivers act based on their perceived reality which differs from the physical reality of the accident reconstruction diagram. The second part announces its method: the application of scientific research. Specifically, the science in question is experimental psychology. Much of this book reads like an introductory text on experimental psychology, albeit with a distinctly applied slant. This is necessary. There are frequent misunderstandings about the definition of human factors. It is best described as a branch of experimental psychology. Human factors applies experimental psychology data to guide the design of objects and environments so that they that fit human abilities and are easy and safe to use. This book's underlying thesis is that knowledge of the science is a necessary but not sufficient condition for understanding roadway human factors. The key word in the title is "From" because there is a catch-22. Controlled research has inherent characteristics which differ from real-world conditions. Scientific research is generally conducted in highly simplified and artificial situations with unrepresentative subjects and drivers. Scientific research data cannot then be directly applied to the real-world. The step from science to application is far greater than many imagine, probably because there are so few who are well versed in both. The book also introduces areas of science that are unfamiliar to most who investigate collisions. "Ecological optics" is a discipline of perceptual psychology that is key in understanding vehicle guidance and collision avoidance. "Visual psychophysics" is the psychological science that underlies visibility and all other sensory judgments. "Operant learning" is the psychological science of adaptability and behavior change based on the consequences of action. The book also introduces more specific concepts that are important but seldom figured into collision analysis. These include notions such as affordances and action boundaries, system tolerances, crowding, and response conflicts"--
Over 200 must-have accident reconstruction formulas at your fingertips in this revised Third Edition. This unique resource is designed to provide, in an easy to use format, the majority of the equations needed for accident reconstruction and investigation. Designed for flexibility and ease of use, each equation is expressed in three formats: algebraic; modified long form; and spreadsheet format. Formulas and constants for converting between metric and imperial units are provided for worldwide use.
This is a guide to recommended practices for crime scene investigation. The guide is presented in five major sections, with sub-sections as noted: (1) Arriving at the Scene: Initial Response/Prioritization of Efforts (receipt of information, safety procedures, emergency care, secure and control persons at the scene, boundaries, turn over control of the scene and brief investigator/s in charge, document actions and observations); (2) Preliminary Documentation and Evaluation of the Scene (scene assessment, "walk-through" and initial documentation); (3) Processing the Scene (team composition, contamination control, documentation and prioritize, collect, preserve, inventory, package, transport, and submit evidence); (4) Completing and Recording the Crime Scene Investigation (establish debriefing team, perform final survey, document the scene); and (5) Crime Scene Equipment (initial responding officers, investigator/evidence technician, evidence collection kits).
Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
This Guide is intended to provide state departments of transportation (DOT) and LTAP/TTAP centers with an easy-to-use resource for implementing or enhancing a Safety Circuit Rider (SCR) program. The Guide includes common characteristics of existing SCR programs and the safety circuit riders. The Guide also includes information on the typical duties and services provided by SCR programs, lessons learned by existing programs, and evidence of the effectiveness of existing SCR programs.
