In the world the road traffic accidents are in the 3rd place at WHO cause-of-death statistics. One of the main causes of these accidents is driving fatigue as results of stress. The aim of this study is to monitoring the heart rate variability for identifying the grade of stress of the drivers.
Material and method: For this stage of the study we design and build an device that recording the ECG signal and the heart rate. We analysed of line the heart rate variability for determining one possible link between the grade of fatigue and heart rate variability. The device use only two electrodes placed on the steering wheel.
Results: We use three categories of subjects: beginner drivers, amateur drivers with more than 3 year experience, and expert drivers. The monitoring is made for 30 minutes in intensive traffic.
Conclusion: The preliminary results are satisfactory which determine us to continuing the research in this direction.
