Expert Witness Services INC.
Providing Scientific Evidence Evaluation and Event Reconstruction in matters involving personal injury, property damage, or product failure or malfunction.
Dedicated to Results
The staff at Expert Witness Services, Inc. specializes in evaluating physical evidence involved, or potentially involved, in litigation from the viewpoint of the Natural Sciences (mathematics, physics, chemistry, etc.) and Biological Sciences (biology, medicine, anthropology, etc.) and reporting what the evidence indicates with regards to a case.
Specializing in
- Event Reconstruction
- The analysis of a sequence of events which lead up to injury, loss of property, or loss of life. Includes Vehicle Accident Reconstruction
- Vehicle Accident Reconstruction
- Vehicle Type
- Cars, Pedestrians, Motorcycles, Bikes, Skateboards, Trucks, Buses, Semis, Fork-Lifts, Tractors, Cranes
- Accident Type
- Two-Vehicle, Multi-Vehicle, Solo Vehicle, Vehicle Bike, Vehicle Pedestrian
- Vehicle Type
- Traffic Signal Timing
- The analysis of traffic light signal timing relating to vehicle accident reconstruction in order to attempt to determine the process of a signalized intersection through its cycle and, ultimately, who most likely entered the intersection on a green indication.
- Biomechanics and Biodynamics
-
The application of energy and forces involved in the movement of a biological entity (living things) & the principles of levers, forces, time, and distance are applied to bones, muscle, and tissue, rather than boards, fenders, and tires.
-
- Human Factors
-
The evaluation of the Human part of an event. The consideration of the psychological and physiological aspects of the interactions of the human with “his” environment. Such aspects as visual perception vs. seeing, cognition, interpretation of sensory cues, and “normal” performance under a particular set of psychological, physiological, and environmental conditions are considered. Body movements, “goodness of fit” of person to the environment, perception of risk vs. safety vs. danger, and expectancy factors are also considered.
