Research on the Impact of Divers' Heart Rate on Longitudinal Slope of Freeway Tunnel
Jianyou Zhao, He Cao, Yanni hi · 2009
This paper researched the longitudinal slope of a tunnel from the driver's psychological view, and analyzed the heart rate changes in different drivers. According to the measured data, we established the quantitative model between the driver's physiological and psychological response by an increased heart rate, and the longitudinal slope of the tunnel and running speed with a regression analysis. This model proved capable of describing the response of drivers driving through the contrast between field data and model calculated data. Finally, we calculated a safe slope of the tunnel and security pace value according to the model.
