Human Factors

Our human factors analyses explain how perception, nighttime vision, comprehension, attention, and decision-making contribute to an incident. We assess what most people in that particular situation could or should have seen, when they could react, and how situational factors affected their response.

Services include:

  • Perception–reaction time analysis

  • Visibility and conspicuity assessments

  • Driver attention, workload, and expectancy evaluation

  • Driver behavior

  • Signs and warnings

  • Lighting and environmental condition analysis

  • Ergonomics and user-interface assessments

  • Waiver assessments
