Psychological Characteristics of Elderly Drivers in Risk Scenarios Based on Heart Rate Variability
Publication: CICTP 2021
ABSTRACT
To study the differences in psychological characteristics between elderly drivers and young and middle-aged drivers in risk situations, and to determine the decline of psychological characteristics of elderly drivers, five experimental scenarios with different risk levels were designed. Drivers’ heart rate variability frequency and time domain data were extracted by physiological instruments, and the two groups’ HRV indicators were compared and analyzed. Results show that the frequency domain index LF and LF/HF of the two groups both increase with the rise of risk grade, while the time domain index SDNN of HRV decreases with the rise of risk grade. In addition, the SDNN index of elderly drivers declined by 29.14%, indicating that the operating load of elderly drivers is relatively higher in risk scenarios. Compared with young and middle-aged drivers, elderly drivers require greater mental effort to deal with risks, which increases the probability of accidents among elderly drivers.
