TOPIC: Computer Technology in Forensic Collision Analysis

Forensic analysis of motor vehicle collisions has become a valuable tool in the handling of motor vehicle collisions, both serious and minor, in the civil or criminal arena.

Collision analysis techniques have traditionally been limited to relatively simple calculations based on the conservation of momentum in two dimensions, supplemented by estimation of collision energy from crush. Limitations to this method of analysis are particularly significant in scenarios involving curved trajectories, co-linear (or nearly so) impact headings, and complex post-impact behaviour over multiple surfaces.

Increased computing power has permitted more sophisticated analysis of post-impact trajectories on the basis of tire models. Considerations such as asymmetric braking, steering inputs, suspension effects, and surface topography can be incorporated into such an analysis.

The results of such simulations permit close matching of observed evidence such as tire marks or gouges, resulting in a high degree of confidence in the accuracy of the resultant analyses. Near-photorealistic animations can also be produced to illustrate the results of the analysis in a format readily accessible to a court proceeding or to the lay person.

Recent advances in in-vehicle diagnostics have permitted the development of supplemental "black box" technology that can provide additional data to the investigator.
