Human cognitive reliability analysis on drivers using simulator experiments

To evaluate driver responses during the process of perception, the response time from the point when subjects detect stimuli presented in their field of view was investigated from the viewpoint of human cognitive reliability. The period of time required for a subject to stop the car when an obstacle appears on the road is obtained through conducting a driving simulation braking experiment. Using the human cognitive reliability model, we evaluated the effect of several performance shaping factors (PSFs), such as experience, stress level and quality of the interface device, on response time. We found that response times for perception, cognition and action of the driver corresponded to rule-based, knowledge-based and skill-based behaviors. It was shown that the effect of the PSFs yielded response times that can be predicted using the proposed human cognitive reliability analysis.
