Accident Reconstruction Expert Witness

Specialties & Experience of this Expert Witness

Additional Information

Christopher is an accident reconstructionist who holds ACTAR accreditation, an Engineer‑in‑Training (EIT) designation, and certification as an Associate Ergonomics Professional  (AEP) through the Board of Certification in Professional Ergonomics (BCPE). He brings both law enforcement experience and private consulting expertise to the analysis and reconstruction of traffic collisions and related events. His firm, Rule 62 Consulting LLC, provides technical analysis, site documentation, and human factors evaluation for criminal, civil, and administrative matters. Christopher's background includes service with a state police accident reconstruction unit followed by several years in private practice. He combines investigative field experience with data‑driven modeling techniques to address questions of speed, timing, visibility, and driver perception objectively and reproducibly. Mr. Kennedy is licensed as an FAA Part 107 Remote Pilot and incorporates UAV‑based aerial imagery into scene documentation and photogrammetric modeling. He documents scenes using aerial and terrestrial photography, photogrammetry, and UAV‑based mapping to produce scaled three‑dimensional models of collision environments. Kennedy downloads and analyzes electronic data from Event Data Recorders (EDR) to evaluate pre‑impact speeds, braking, steering inputs, airbag timing, restraint performance, and the resultant delta-V from impact forces and crash orientation. These data are integrated to build reconstructions that are physically consistent and supported by measurable evidence. As an AEP‑certified human‑factors specialist, Christopher conducts perceptual and ergonomic analyses to address visibility, perception‑response time, and driver expectation. His work includes nighttime visibility and line‑of‑sight studies, as well as quantifying reasonable perception‑response times using human‑factors analysis software. His focus is on presenting findings in clear, practical language that decision‑makers and juries can understand. Christopher employs simulation and analytical tools to model vehicle motion, timing, and collision mechanics. Sensitivity analysis and physical validation techniques are applied to evaluate alternate scenarios and assess uncertainty. The goal in each case is to identify the range of physically reasonable outcomes and communicate them transparently.
