Traffic collision reconstruction : ウィキペディア英語版 | Traffic collision reconstruction
Vehicular accident reconstruction is the scientific process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. Reconstructionists are employed to conduct in-depth collision analysis and reconstruction to identify the collision causation and contributing factors in different types of collisions, including the role of the driver(s), vehicle(s), roadway and the environment. The laws of physics and engineering principles such as the conservation of linear momentum, work-energy methods, and kinematics are the basis for these analysis and may make use of software to calculate useful quantities. The accident reconstruction provides rigorous analysis that an expert witnesses can present at trial. Accident reconstructions are done in cases involving fatalities, and often when personal injury is involved. Results from accident reconstructions are also useful in developing recommendations for making roads and highways safer, as well as improving safety aspects of motor vehicle designs. These reconstructions are often conducted by forensic engineers, specialized units in law enforcement agencies, or private consultants. == History ==
The National Highway Traffic Safety Administration funded the first national guidelines for the standardization training in the field of traffic accident reconstruction in 1985. This led to the establishment of Accreditation Commission for Traffic Accident Reconstruction (ACTAR), an industry accreditation group.〔(The History of ACTAR ), Retrieved on Feb. 22, 2010.〕 This field of motorcycle accident research was pioneered by Hugh H. Hurt Jr. His meticulous accident reconstructions of motorcycle accidents helped to explain that proper helmets reduced head injuries, most motorcyclists needed more driver training to control skids, and a large percentage of motorcycle accidents involved left-turning automobiles turning in front of the oncoming motorcycle.〔(Hugh Hurt Jr., Engineer Who Studied Motorcycle Accidents, Dies at 81 ), Martin, Douglas, ''The New York Times'', 2009-12-03. Retrieved on Feb. 23, 2010.〕
