The reconstruction of a rollover accident is a complex and challenging problem. The analysis and reconstruction of these accidents requires one to investigate various phases of the accident. They include the pre-trip, trip and post-trip phases as well as the occupant kinematics. A good presentation of the reconstruction is essential and requires proper graphical aids, scale models and perhaps animation. It is the purpose of this paper to introduce reconstruction analysis techniques and presentation procedures that will address the various phases of a rollover accident and assist the analyst in his reconstruction and presentation.

Motor vehicle accident reconstruction has become a very recognized and essential part of the extensions and applications of engineering training. This is due to the increasing litigious trends of our society. This paper begins by defining a motor vehicle accident reconstruction and proceeds to discuss the qualifications and responsibilities of an accident reconstructionist. Additionally, considerable emphasis is placed upon defining procedures for performing the various tasks that are involved in a reconstruction. Also, the initial investigation, the litigation process and ultimately the rendering of expert witness testimony at the trial are discussed.

Personal injury litigation continues to increase at an alarming rate. Many of these law suits which involve vehicular accidents require not only a thorough knowledge of various engineering disciplines but also necessitate a clear and effective presentation for the jurors. For the presentation to be effective, the event should be depicted in a concise and lucid manner. This paper discusses various techniques which the authors have found to be effective in legal cases.

Accident reconstruction involves an explanation or re-enactment of how an accident occurred. This account must be based upon physical evidence and all available facts pertaining to the accident. Moreover, this explication must be lucid and appealing to the audience that is being addressed. The objective of this paper is to introduce a procedure for presenting an accident reconstruction in a clear and effective manner. The technique that is discussed herein consists of constructing three-dimensional models of an accident scenario for later filming with still and video cameras. The reconstruction is then presented by means of 35mm or medium format slides and real time video animation- Several reconstructions which illustrate the methodology end have been used in litigation are presented.
