The Practical Application of Finite Difference Analysis in Accident Reconstruction

The effective application of a Finite Difference Analysis routine in accident reconstruction is demonstrated. Such analysis finds not only the central value but the reliability side-bands; not only the mean but the probable extremes of the analysis, given the probable investigative reliability.

Furthermore, because the controlling transfer functions depend only on the physics of the event, the side-band spans found by one means of reconstruction apply also to the central values found by some other means. Such ubiquity allows the practitioner to add to pre-existing central results the probable bounds of those results due to the practical limitations of investigative accuracy.
