Research on the Effect of Alignments of Mountainous Highways on Driver Characteristics

Abstract:

Fatigue driving becomes a main hidden danger for traffic safety and endangers peoples life and property seriously.This paper is to obtain the effect of alignments of mountainous highways on driver characteristics. this paper combines with all kinds of theoretical methods and research means on physiology, medical psychology and engineering psychology, then this paper models regression equation on driver's growth rate of Heart Rate and alignments index of mountainous highways, and analyses driver's heart rate variability (HRV). The results show that: when the slope of long downhill is about 3.5%, drivers growth rate of HR exceeds 40%, which is the most nervous state. And during the downhill, the value of LF / HF appears to be rising, which indicates that the more active of the drivers sympathetic nerve, the more likely to be tired. The study has a certain realistic guiding significance on mountain highways slop design and fatigue driving alarm. This acquisition system is easy to operate with high accuracy which can meet the all-weather, dynamic monitoring and real-time processing requirements. Aim at the national highway 321 that from Guilin to Longsheng, the research on the design and revise of the highway slope has a certain realistic guiding significance.
