Examining internal and external factors contributing to accidents
Exponent's team investigates both human performance and circumstantial issues that are key considerations in investigations, including visual and auditory perceptions, reaction time, attention or distraction, and fatigue; environmental aspects such as weather, lighting, and background noise; and operator traits like age, strength, size, and experience.
Exponent's extensive investigations yield evidence-based insights into the ways humans interact with products, technology, and systems, as well as what internal and external factors may have been at play during an accident. Our human factors scientists and engineers are uniquely qualified to analyze the behavioral traits and capabilities of people in different roles, including operators, pedestrians, drivers, and eyewitnesses.
Services
For 50+ years, we’ve thrived on solving unstructured problems that require bespoke solutions. Some of our services include:
• Assess human performance as a contributor to accident causation
• Analyze the visibility and available lines of sight in a visual environment
• Create perceptually accurate reproductions of low-illumination scenes
• Evaluate the likely effectiveness of additional or alternative safety-related information, guarding, or design interventions in accident avoidance
• Determine the role of attention and distraction on human behavior and safety-related actions
• Characterize human memory, information processing, and the potential for inaccuracies in eyewitness testimony
• Evaluate hindsight bias — the effect that knowledge of an outcome has on the perception and interpretation of prior events
• Consider potential for accident avoidance given human perception-reaction times
• Assess the potential effects of age, drugs, and/or alcohol, and existing medical conditions on human performance
• Evaluate the ability of the visual system to process and identify a potential hazard to avoid an accident
• Document accident scenes or in a site-inspection/recreation environment
