How Perceptual and Cognitive Factors
are Involved in a Car Accident:
A Case Study

By: Vanessa Dominguez & Marc Gentzler | Mentor: Dr. Andrew P. Daire


Several factors are considered in car accident analysis. Human factors research has shown that different perceptual and cognitive factors influence driving performance, leading to improvements in vehicle and road design. This case study provides a deeper understanding of the potential influence of major perceptual and cognitive variables on driving performance in general, including (a) driver expectancy effects, (b) glare, (c) general visibility such as lighting, (d) driver's dark adaptation, (e) road illusions, and (f) driver perception-reaction time. This analysis describes in detail how these certain perceptual and cognitive factors may have been involved in a particular car accident. Future research suggestions to improve driver safety and traffic regulations are provided.

KEY WORDS: car accident analysis, perception effects, glare, general visibility, dark adaptation, road illusions, perception-reaction time
