Abstract
The reconstruction of a traffic accident depends in the accuracy of data collected on the scene and subsequent to the accident. The objective of traffic accident reconstruction is to describe the events of the accident, including the position of the road, facing or heading direction, speed, direction of travel, acceleration or deceleration and rotation of each vehicle or pedestrian involved. The calculations required for each stage of an accident reconstruction are fully described and charts of various speed, acceleration, and deceleration forces involved in an accident are provided.
