Influence Of Radius Of Horizontal Curve On Driver'S Psychology And Physiology On The Two-Lane Mountain Highway

At the present time, the accident remains at a high level all over the world. It mostly happened on the two-lane mountain highway. Through analysis of the relationship between radius of horizontal curve and driving safety of the drivers on two-lane mountain highway, variations of heart rate was be introduced. The variations of heart rate will be changed with Radius of horizontal curve through qualitatively and quantitatively analysis. However, the maximum of drivers' heart rate does not occur on the limit radius of horizontal curve. It locates at the place slightly larger than the limit radius of horizontal curve. The model between heart rate variation and radius of horizontal curve square was established. Finally, some useful advises were suggested to strengthen the two-lane highway management.
