Key result
A method selecting individualized physiological indices from heart rate and respiration detected tension and non-tension states during simulated driving with an error rate of less than 15%.
Why the study?
The study was conducted to evaluate a method for detecting mental and physical states that may interfere with driving using physiological data.
Observational (n=26)
No
Physiological indices such as heart rate, respiration, and brain activity can be used to estimate the mental and physical states of drivers, showing a weak correlation with resilience.
Using physiological data from a basic experiment simulating railroad driving in general participants, we studied a method for detecting mental and physical states that may interfere with driving. As a result, characteristic changes in brain activity are observed in the group that experienced a psychological upset. In addition, we selected heart rate and respiration as physiological indices that can be easily measured during driving and proposed a method for selecting effective indices for estimating mental and physical states for each individual. We examine the relationship between brain activity associated with psychological agitation and a questionnaire score on resilience (ability to adapt well) and found a weak correlation between them.

NAKAGAWA et al. (2022) conducted an observational in Healthy drivers (simulated) (n=26). Psychological agitation (sound stimulus) and simulated driving tasks vs. Baseline or non-tension state was evaluated on Detection of tension and non-tension states using physiological indices (heart rate and respiration). A method selecting individualized physiological indices from heart rate and respiration detected tension and non-tension states during simulated driving with an error rate of less than 15%.
