Analysis of driver's ECG signal based on the prairie road environment with limited speed driving

摘要

Research finding show: Basing on field survey and statistical analysis, long line is main alignment of the grassland road and the horizontal curve radius is large. Landscape of grassland road is single and traffic flow is less. And practical operation speed is higher than design speed. Basing on this finding, the relationship between grassland road environment and heart rate, HR growth rate of driver is further researched in following field experiment. Research finding show: with the increase of driving time, driver's heart growth rate has a declining trend. It has large scale of change in 26–30 minute period. Through subjective questionnaire survey, it shows that 80% of drivers have discomfort or fatigue at the same time.
