Abstract: (2529 Views)
Background and Objective: The reduction in driver mental performance can lead to driving errors and accidents. Given the importance of mental performance in driving and the limited research background on the effects of physical environmental factors on drivers' cognitive performance, this study aimed to develop a method to analyze the short-term effects of exposure to noise, vibration, and unconventional temperature conditions on physiological and neurophysiological responses in driving using a simulator.
Materials and Methods: This research was conducted in a laboratory setting with the participation of 43 drivers. After meeting the entry criteria for the study and receiving preliminary training, the drivers were exposed to traffic noise, whole-body vibration, and temperature changes both individually and in combination. The effects of these factors were assessed using cognitive tests and physiological measurements. Subsequently, a statistical model was developed to predict the impact of these factors on cognitive performance and arousal.
Results: The results showed that the respiration rate increased with higher vibrations and noise, while systolic blood pressure rose in response to increased vibrations and decreased ambient temperature. The NN Mean, RMSSD, and SDNN indices were associated with vibration and temperature, while the LF/HF index was related to noise and temperature. In addition to environmental factors, age and body mass index were also significantly associated with changes in some of the studied indices.
Conclusion: Based on the results of the study, it was found that environmental factors had significant effects on physiological and neurophysiological responses. The simultaneous use of both physiological and neurophysiological responses provides a better explanation for the mechanism of environmental factors on drivers' performance. The results of this study may serve as a foundation for field research.
