Summaries of these course descriptions for each elective appear below. A lock ( A mark made by a bouncing braked wheel. After an accident has occurred, there are a minimal number of low speed crash tests to assist the accident reconstructionist/engineer in determining the speed of a vehicle from little or no visible vehicle damage. Drag Factor is the deceleration coefficient for an entire vehicle. Vehicle-vs.-pedestrian and vehicle-vs.-bicycle crashes often result in severe injuries to the pedestrian or rider, escalating the importance of investigating and reconstructing these crashes. The speed differential between two vehicles traveling on the same line. A permanent landmark used to measure and locate the position of important spots in a crash scene. Usually related to a missing or under-inflated tire. Collision Reconstruction with CDR Application, Adv. Relatively little effort has been devoted to quantitatively comparing vehicle and occupant responses under different braking and awareness. Various scientific instruments (for example, the VC-3000) determines the drag factor of a roadway surface. Eight volunteers were used in a series of twenty-five staged side impact collisions with impact speeds ranging from approximately 2 km/h to 10 km/h and impact configurations to the front, middle and rear side portions of the vehicle. Acceleration can be either positive or negative (deceleration). To help the accident reconstructionist in this effort, a series of crash tests were conducted to relate the impact velocity of the striking vehicle to the throw distance for the cyclist. The main reason for this is that the drag factor is dependent on the roughness of the surface Building upon the Traffic Crash Reconstruction 1 & 2 curriculum, this advanced reconstruction course focuses on understanding and assessing the human role in the crash sequence. %PDF-1.5 Scuff marks are relatively volatile and can disappear very quickly if the roadway is exposed to traffic.
