CASE-001 // Rear-End · OR Highway · Defense
High-Speed Rear-End Collision — State Highway Intersection
A vehicle traveling at high speed struck a turning vehicle at a rural highway
intersection. EDR data was extracted from both vehicles and analyzed alongside
momentum-based speed estimates. Human factors analysis addressed looming theory
and gap acceptance. Aerial scene documentation was completed by drone.
Expert report and deposition testimony provided for defense counsel.

Intersection T-Bone — Signal Timing & Perception-Reaction
A broadside collision at a signalized intersection involved disputed claims about
signal phase and driver perception-reaction time. Speed at impact was calculated
using energy methods and corroborated by EDR data. Signal timing records were
obtained and analyzed. 3D laser scan of the intersection produced a measurable
scene model for trial exhibit preparation.

CASE-003 // CMV · Highway · Plaintiff
Commercial Truck Rear-End — ELD Data & FMCSR Compliance
A semi-truck rear-ended a passenger vehicle on an interstate. ELD records were
obtained and analyzed for hours of service compliance. ECM data was extracted and
provided pre-crash speed, braking, and cruise control engagement. FMCSR inspection
records were reviewed. Federal CMV Inspector certification supported a full
mechanical compliance evaluation.

CASE-004 // Pedestrian · Urban · Defense
Pedestrian Fatality — Visibility & Speed Analysis
A pedestrian was struck at night on a non-intersection roadway. Reconstruction
addressed headlamp illumination distance, pedestrian conspicuity, and driver
available perception-reaction distance. Speed was estimated from tire mark
analysis and compared against EDR data. Human factors research on nighttime
pedestrian detection informed the report and testimony.

CASE-005 // Rollover · Rural · Defense
Single-Vehicle Rollover — Speed & Critical Curve Speed
A single-vehicle rollover on a rural curve involved disputed claims about road
design and vehicle speed. Critical curve speed was calculated using surveyed
roadway geometry. EDR data confirmed pre-crash speed and steering input. Drone
aerial photography documented the scene geometry and evidence distribution.

CASE-006 // Motorcycle · Intersection · Plaintiff
Motorcycle Collision — Gap Acceptance & Perception Analysis
A motorcycle was struck by a left-turning vehicle at an unsignalized intersection.
Speed of the motorcycle at the point of perception was a central issue. Gap
acceptance research and closing speed analysis addressed what the turning driver
could and should have perceived. Reconstruction incorporated skid mark analysis
and EDR data from the subject vehicle.
